Thank you.

Hello, everyone. I would like to thank you all for attending our Q3 2023 Financial Results Conference call. I'm here with Robert Lugens, our Head of Discovery Biology, and Michael Kachef, our Head of Translational Sciences. I draw your attention to the press release and the financial statements issued earlier today, which are available on our website. I also draw your attention to our disclaimer. We will be making certain forward-looking statements that are based on the knowledge we have today. I will start this conference call by giving a quick overview of our recent achievements before handing over to Robert and Michele, who will review our clinical and preclinical pipeline. I will then review our Q3 preliminary financial results. Following that, we will open the call for Q&A. Starting with the highlights, our partner, Janssen, completed recruitment of the ADX 71149 Phase II Epilepsy Study earlier this month, and we confirmed that data is expected in Q2 2024. I'd like to remind you that an independent interim review committee established by Janssen to review the unblinded data from part one of cohort one made its recommendation to continue the study. This recommendation and the decision of Janssen to continue the study is very encouraging and suggests that 149 is safe and well tolerated and may be having a positive impact on this patient population. We have made substantial progress in our collaboration with our partner, Indivior, and advancing several novel GABA-B compounds through candidate selection. As a reminder, Indivior's primary interest is in substance use disorder, and under the agreement, we have retained the right to select drug candidates for development in certain exclusive reserved indications. We are focusing our independent program on COFF, During Q3, we have continued to advance compounds through clinical candidate selection, multiple compounds showing excellent efficacy in multiple preclinical . In Q3, we announced the extension of our collaboration through June 2024, with 2.7 million Swiss francs of additional research funding committed by Indivior. We expect Indivior and ourselves to select compounds to advance into ING-enabling studies in 2024. We lead a consortium which has secured 4 million Euro grant to advance our mGluR2 negative modulator cognition program through lead optimization to clinical candidate selection phase. We also continue to believe there is value in diproglurant, our phase two ready compound, and have substantially completed our evaluation of the future development Post-stroke recovery is an interesting area for future development and are currently profiling preclinical models of post-stroke recovery. Furthermore, preclinical data was recently published in the journal Brain, which strongly supports the rationale for the inhibition of F5 receptors as a treatment for post-stroke recovery and the development of diprocloron in this important unmet medical need. We are in parallel pursuing discussions with potential partners to advance future development of Diplorant. And last but not least, our M4 PAM program for schizophrenia, which is now a priority program for us, continues to make rapid progress through clinical candidate selection based and is on track to start IND enabling studies in the second half of next year. From a financial perspective, we continue to pursue discussions with potential partners across the portfolio and tightly control costs. As of today, we estimate that our cash reserve provides us with a runway through Q1 2024. Now I will hand over to Robert, who will give you some more details about our existing pipeline.

Thanks, Tim. Hello, everyone. I will start by speaking about our Phase 2 Epilepsy Study with ADX 71149, which is being executed by Janssen. Janssen is making excellent progress and has recently completed recruitment of 110 patients across two cohorts. Epilepsy is a large, multibillion-dollar market opportunity where, despite several available treatments, many patients are still in need of improved therapies to treat the disease. As a reminder, ADX71149 is a metabotopic glutamate receptor subtype 2, or Mglu2, positive allosteric modulator discovered in partnership with Janssen using ADX's proprietary allosteric modulation platform. ADX71149 has demonstrated both thermal amnificancy and a strong synergistic effect in combination with inhibitors of SV2A, such as Capra and Breviact. ADX149 has also been thoroughly profiled in preclinical and clinical studies by Janssen, demonstrating its good safety and tolerability profile in healthy volunteers and patients. Janssen is responsible for development and are currently operationally executing both the phase two study and an open label extension study in epilepsy patients. We have significant economics in our deal with Janssen with pre-launch milestones of 109 million euros, low double-digit royalties on net sales, and Janssen is responsible for all development costs. To illustrate the synergistic effect seen with the combination of 149-Anevistiatam, the active molecule in Keppra, here is the data obtained in the 6-hertz psychomotor seizure model, widely recognized as having high translational value to characterize the efficacy of anti-epileptic drugs. As a reminder, ADX7149 given alone in this model produces a robust protection against 6-hertz with an ED50 determined to be approximately 20 milligrams per kilo. In combination studies with varying doses of levetiracetam, a fixed dose of 149 increased the potency of levetiracetam, leading to an approximate 35-fold shift in ED50. Conversely, using a fixed dose of levetiracetam with varying doses of ADX71149, Levitiracetam increased the potency of 149, leading to an approximate 14-fold shift in its ED50, suggesting a positive pharmacodynamic relationship or strong synergistic effects for the two molecules when given in combination. This extraordinary effect of a combination of an mGlu2-PAM with an SV2A antagonist has been patented, offering a strong protection for this program until 2021. 2035 without additional extensions. This is the Phase II study design. The study is a double-blind, placebo-controlled proof-of-concept study enrolling patients with focal onset diseases who have suboptimal response to treatment with CAPRA or Breviac. As mentioned, the study has completed recruitment of 110 patients across two cohorts evaluating two doses. In this phase two study design, patients establish a 28-day seizure count over a 56-day baseline period prior to being randomized to receive either or matching placebo. The primary endpoint is the time taken to return to their monthly baseline seizure count. The study has two parts, part one being the four-week acute efficacy phase and the part two being an eight-week maintenance of efficacy phase. Part two includes patients who did not reach their baseline seizure count during part one of study and continue on their randomized drug or placebo. An open-label extension study is ongoing in parallel, offering all patients the opportunity to get treated with 71149 in combination with Levitiracetam or Brivaracetam. As previously announced in May, an independent interim review committee convened by our collaboration partner recommended to continue the study following review of unblinded data from Part 1, Patient Court 1. This was encouraging news, suggesting 149 is safe and well-tolerated and potentially offering benefits to epilepsy patients. We look forward to sharing the top line with these data, of course, 1 and 2, in Q2 of 2024. I now pass it over to Misha. will update you on the depregulant and GABA-BPAM programs.

Thank you, Robert. Following termination of the development program in PD-LID, we embarked on the detailed evaluation of a number of potential indications of interest for future development, including substance use disorder, migraine, and other forms of pain. We have completed this at the time and have identified post-stroke recovery as an interesting indication for the future development of depremnurant. We believe the differentiated profile of depremnurant makes it particularly useful for post-stroke recovery. There is a large unmet medical need in post-stroke recovery and rehabilitation. Stroke is among leading causes of chronic, often lifelong disability. as it leads to motor, sensory, cognitive impairments, and multiple comorbidities. There are over 100 million stroke survivors worldwide, and the number is growing at the annual rate of 12 million. A variety of rehabilitation therapies are used with post-stroke patients, but the recovery is slow and inadequate. there is an urgent need for pharmacological agents that can facilitate the recovery stimulated by rehabilitation therapies. mGluR5 receptor is a suitable target to address post-stroke recovery as it is densely expressed in the brain, involved in neuroplasticity, and modulates excitatory-inhibitory equilibrium. In fact, activation of mGluR5 receptor has been observed in a range of neurological disorders, including stroke, where it plays a role in maladaptive rewiring of the brain following stroke. Inhibition of MWR5, on the other hand, can facilitate adaptive rewiring of the brain, promoting neuroplasticity and creating of new functional pathways moving the neural network towards a pre-lesion state. Exciting new evidence recently published in the journal Brain, suggests that negative ulcerative modulator of MGOR5 receptor, MTEP, at least daily in rats following stroke, results in a sustained and growing improvement in sensory motor function in comparison to vehicle treatment. Similar improvement in sensory motor function was observed in animals treated with our mGUR5-NAM depragurant. MRI imaging of the resting state functional connectivity in post-stroke rodents shows that daily administration of MTAP also stimulates intra- and inter-hemispheric connectivity in the brain disrupted by stroke. It is important to note that improvement in brain connectivity after stroke is known to correlate with functional recovery and is observed across species. Dipragluron is ideally suited to be used in tandem with rehabilitation therapies in post-stroke patients and as it has a fast onset of action and short half-life. It has shown good tolerability in healthy subjects and in Parkinsonian patients showing only mild to moderate CNS-related adverse effects. We have drug product ready, patent position, and believe Dipranglion can become a first-in-class drug to facilitate post-stroke recovery. Let me now switch to our preclinical programs, starting with our GABA-B positive allosteric modulator program, which is partnered with Indivior. The aim of this collaboration is to deliver a new treatment for substance abuse disorders. INDIVIOR is supporting the research at ADEX and has recently committed an additional 2.7 million Swiss Francs funding for us to complete clinical candidate selection activities, in addition to 13.8 Swiss Francs total funding so far. As a reminder, GABA-B receptor activation has been clinically validated in a number of disease areas using Buclofen, a GABA-B autosteric agonist. Buclofen is an FDA-approved drug for treatment of spasticity and is widely used off-label to treat numerous diseases, including substance use disorder. However, Buclofen has a short half-life and comes with significant side effects hampering its wider use. Thus, there is a strong need for a better Baclofen. We believe that we can achieve this positive modulator approach and their differentiated pharmacology having the efficacy of Baclofen but longer half-life and improved side effect profile. We are well on our way to meeting with multiple novel drug candidates rapidly advancing through clinical candidate selection phase. with the aim to nominate drug candidates to enter IND-enabling studies in 2024. As part of our agreement with INDIVIOR, we have the right to select drug candidates from the funded research activities for our own independent GABA-B-PAM program. We have selected to focus our independent program on COF, And therefore, I will present this exciting opportunity. There is a strong rationale for developing GABA-B PAMs for chronic cough. Chronic cough is a persistent cough that lasts for more than eight weeks and can be caused by a variety of factors, including respiratory infections, asthma, allergies, and acid reflux, but also possibly by an overactive cough reflex. There is a large unmet medical need in novel anti-juice drugs as current standards of care are ineffective in 30% of patients and only moderately effective in up to 60% of patients. In addition, the current treatments carry risks of serious side effects. Support for using GABA-B PAMs in treatment of chronic cough comes from the clinical evidence GABA-B agonist is used off-label in COV patients and from the anatomical evidence that GABA-B receptors are strongly expressed in airways and in the neural pathway regulating COV. Therefore, we believe that GABA-B PAMs could offer superior efficacy in COV patients. On the next slide, we show that GABA-BPAMs are likely to have a superior vulnerability profile in comparison to the current standards of care, and show no taste-related side effects, as seen with the newly approved P2X3 inhibitor, gefabixant. Therefore, we believe that GABA-BPAMs could be an innovative new treatment of chronic cough administered once daily via oral dosing and offering improved efficacy and tolerability with fewer non-responder patients suitable for chronic dosing, therefore significantly improving patient quality of life. We are working with multiple compounds progressing in late clinical candidate selection phase and we expect to move into IND-enabling studies in 2024 in parallel to delivering compounds to our partner in DVR. I will now pass it back to Robert for an update on our other preclinical programs.

Thanks, Misha. Let me start with an update on our M4 PAM program as a potential novel treatment of schizophrenia and other psychosis. Schizophrenia affects approximately 1% of the world population, and patients have been using the same mechanism of action for the last 50 years with limited efficacy and significant tolerability issues, often leading to treatment discontinuation and relapse. This space is seeing a major breakthrough with the advent of a completely novel approach based on activation of muscarinic M4 acetylcholine receptors. The recent filing of an NDA and acceptance by FDA today of xenomyelin, a non-selective M1, M4 agonist, and a peripherally restricted panmuscarinic antagonist strongly validates the M4 receptor activation approach. In addition, a phase 1B testing of emraclidine, an M4 positive allostatic modulator developed by Cerevel in schizophrenia patients showed an antipsychotic effect, paving the way for our M4 positive allostatic modulator program. of action of muscarinic M4 acetylcholine receptors allows to reduce striatal dopamine tone without directly blocking the dopamine receptors, the strategy used by current antipsychotic agents. This allows to retain a therapeutic effect without the effect of typical and atypical antipsychotics. Standard-of-care antipsychotics, as well as non-selective muscarinic agents, suffer from significant side effects, leading to high treatment discontinuation rates. CAR-XT represents a significant step in providing a new treatment of schizophrenia patients, but poor selectivity of CAR-XT may result in suboptimal tolerability. Our all-state modulation approach is providing many advantages over an agonist approach. in particular with absolute receptor subtype selectivity, and without the potential side effects linked to constant receptor activation, such as receptor desensitization and reduced efficacy due to tolerance. The aim of our M4 positive modulation program is to identify highly selective and brain-penetrant molecules, offering potential best-in-class efficacy and tolerability. We are currently working on highly differentiated and novel chemical series identified from our proprietary chemical library with our specific allosteric modulation biological assays. We have made great progress in optimizing compounds, identifying highly M4 selective compounds, demonstrating an effect in preclinical models of schizophrenia for several lead compounds, and have now entered into clinical candidate selection phase aiming to identify drug candidates to enter IND enabling studies in 2024. Onto our M group 2 negative allostatic modulator program for mild neurocognitive disorders associated with Alzheimer's disease, Parkinson's disease, and depression. The program has been awarded a 4 million euros grant to allow identification of one or more drug candidates to advance into IND . Mild neurocognitive disorder, or MNCD, is the stage between expected cognitive decline of normal aging and the more serious decline of dementia. Besides being potentially the early signs of Alzheimer's disease, MNCD is also often experienced by patients suffering from depression. The prevalence is approximately 15% and augments significantly with age, affecting up to 25% of people aged 80 or more. Interestingly, MNCD is currently viewed as an intervention window for delaying the onset of dementia. Mild neurocognitive disorders, some drugs such as acetylcholinesterase inhibitors are being prescribed but show limited efficacy and come with significant side effects. There is therefore a strong unmet medical need for better treatment options. With the details by inhibiting pre-synaptic Mglu2 receptors, our negative allostatic modulators will counteract the synaptic deficits observed in MNCD by increasing the excitability of neural circuits involved in cognition. This objective was also followed with positive allostatic modulators of AMPA or ampakines, which pharmaceutical companies tried to develop without success. Ampoquines seem to induce class-related side effects, and we strongly believe our mGlu2-Nam approach will successfully address MNCD without having these side effects. Besides being potentially the early sign of Alzheimer's disease, MNCD is also often experienced by patients suffering from depression. Developing mGlu2-Nam offers the exciting opportunity to treat cognitive impairment while also addressing symptoms of depression. Both pro-cognitive and antidepressant effects have been demonstrated in relevant preclinical models with our mGlu2-Nam candidate compound. Our project has been awarded a €4 million grant to identify one or more drug candidates to enter IND-enabling studies. Eurostars funds highly innovative projects to address unmet needs. Therefore, we see this as a significant validation of our project while providing us with funds for three years. HADx will lead a consortium of highly experienced teams with complementary expertise through the series clinical candidate selection phase before identifying clinical drug candidates to enter IND enabling studies by end of 2025. In summary, our drug discovery engine has made great progress with multiple drug candidates advancing towards IND enabling studies. The renewed commitment of our partner Indivio and the recent award of a €4 million grant are further validation of the quality and productivity of our hysteric modulation platform. This concludes our prepared remarks on the progress of our R&D programs and now handed back to Tim.

Thanks Robert. I'll now switch to an overview of the financials. Starting with the income statement, we recognized 0.3 million of income in Q3 compared to 0.4 million in Q3 of 2022. The primary source of revenue is research funding from our collaboration with Indivio. In terms of expenses, R&D expenses were 1.8 million in Q3 2023 compared to 2.8 million in Q3 2022. The decrease of 1 million is primarily due to the termination of development in PDLID in June of 2022. G&A expenses were 1.2 million in Q3 compared to 1.8 million in the same period as 2022. The decrease of 0.6 million is primarily due to reduced share-based service costs and decreased D&O insurance. The finance result is primarily related to foreign exchange gains on US dollar cash deposits and to a lesser extent to interest income. Out of the balance sheet, Our assets are primarily held in cash, and we completed Q3 with 4.8 million Swiss francs of cash held in Swiss francs and U.S. dollars. Other current assets amount to 1 million and primarily relate to prepaid D&O insurance and retirement benefits. Relate to our agreement with Indivior. Current liabilities, 1.9 million. decreased by 1.4 million compared to December 31, 2022 and primarily relate to our R&D payables and accruals. Non-current liabilities of 0.3 million decreased by 2 million compared to December 31, 2022 and primarily relate to retirement benefit obligations. Now, to summarize, So ADX 71149 Phase II Epilepsy Clinical Study completed recruitment of patients and top-line results are expected in Q2 of next year. We believe the recommendation of the Independent Review Committee to continue the study is very encouraging and suggests that 149 could be having positive impact on patients. We continue to believe in the value of DIPRA grant and are completing preclinical profiling in post-stroke recovery. In parallel, we are pursuing collaborative arrangements to advance development and look forward to sharing more information in the future. Our preclinical programs continue to make solid progress towards delivering drug candidates for future clinical development and important therapeutic areas in stress-related disorders, chronic cough, cognition, schizophrenia. As a reminder, our portfolio was discovered in-house from our pioneering Alistair modulator drug discovery platform. Currently, we have significant intellectual property on all programs. We have a track record of securing partnerships at the preclinical stage and supported top-tier investors. We recognize the 2023 stock performance and current market capitalization is very disappointing. However, we are having multiple business discussions across our portfolio and strongly believe that if we are successful in executing our our near-term partnering strategy, then our stock price should move to recognize the value of our portfolio. This concludes the presentation and we will now open the call for questions.

Thank you, dear participants. As a reminder, if you wish to ask a question over the phone, please press star 11 on your telephone keypad and wait for your name to be announced. To withdraw a question, please press star 11 again. Alternatively, you can submit your questions via the webcast. Please stand by.

We'll compile the Q&A roster. This will take a few moments.

Now we're going to take our first question over the phone. And it comes from the line of Leonel Delgado from Baader Haver. Your line is open. Please ask your question.

All right. Thanks for taking the question. So the question is, what can we expect if the epilepsy readout into Q24 is positive? So the question is basically, what is the immediate implication for ADEX in 2024? Thank you.

Yeah, so thanks for the question. Well, the immediate implications for ADEX, well, as you know, Janssen is operationally executing the D. They're responsible for financing the study. So ADDx has very little, well, no control over the future development. And we have very limited visibility. However, we believe that the data that's been generated, because they've looked at two doses. So should the study be positive, then we would expect the program to be moved forward into a PITL study. But again, we don't have visibility on exactly what the plans of Janssen are with respect to future developments.

Thank you. Thank you.

Dear participants, as a reminder, if you wish to ask a question over the phone, please press star 1 1 on your telephone keypad.

Just give us a moment.

At this moment there are no further questions over audio lines and we will proceed to any written questions. And the first question comes from the land of Peter Alec. And the question is, 4 million euros, Eurostars grant, when will the money be paid?

Yeah, so yes, some of that money comes to ADEX and some of that money goes to consortium partners. And we are expecting that money to be or a significant part of money that's allocated to addicts to be received by addicts you know quite soon but we are not providing the details of how that money is split at the current time thank you the next question comes from the land of Jesse Brodkin

In the IRB review of unblinded data from 149, were efficacy measures unblinded? Also, were any changes in dosage made between cohort one and cohort two?

Yeah, so thanks for the question.

Yeah, so the independent interim review committee had some very clear guidance from Janssen. And they were given clear guidance that they should recommend to stop the study if they didn't see a certain level of split between active dose and placebo. And also, of course, if they saw any significant safety issues, then they had to recommend stop. Now, the recommendation to continue means that they must have seen at least a signal of efficacy and no significant safety concerns. And that was cohort one. Now, what we know is that cohort two is a higher dose than cohort one. And this is why we are very encouraged by the combination of the recommendation to continue and the fact that cohort two is a higher dose. And now that they have completed recruitment, we are guaranteed of data.

I hope that answers your question.

Thank you. Dear participants, just a quick reminder, if you wish to ask a question over the phone, please press star 11 on your telephone keypad. Alternatively, you're more welcome to submit any questions via the webcast.

The speakers will just give a moment for the last entries.

Thank you, ladies and gentlemen. This brings the main part of our conference for a close. And I would now like to hand it back to Tim Dyer for any closing remarks.

Well, thank you, everyone, for attending the Q3 conference call and the corporate update. We look forward to speaking to you again soon and just wish you a nice end of your day. Thank you. Bye-bye.

That does conclude our conference for today. Thank you for participating. You may now all disconnect. Have a nice day. Thank you. you Thank you. Thank you. Thank you. Thank you. you

Thank you. Hello, everyone. I would like to thank you all for attending our Q3 2023 Financial Results Conference call.

Indivior is supporting the research at ADEX and has recently committed an additional 2.7 million Swiss francs funding for us to complete clinical candidate selection activities. in addition to 13 points, including Chris Frank's total funding so far. As a reminder, GABA-B receptor activation has been clinically validated in a number of disease areas using Baclofen, a GABA-B autosteric agonist. Baclofen is an FDA-approved drug for treatment of spasticity and is widely used off-label to treat numerous diseases, including substance use disorder. However, Baclofen has a short half-life and comes with significant side effects hampering its wider use. Thus, there is a strong need for a better Baclofen. We believe that we can achieve this positive modulator approach and their differentiated pharmacology having the efficacy of Baclofen but longer half-life and improved side effect profile. We are well on our way to meeting with multiple novel drug candidates rapidly advancing through clinical candidate selection phase with the aim to nominate drug candidates to enter IND-enabling studies in 2024. As part of our agreement with Indivior, we have the right to select drug candidates from the funded research activities for our own independent GABA-B PAM program. We have selected to focus our independent program on cough. Therefore, I will present this exciting opportunity. There is a strong rationale for developing GABA-B PAMs for chronic cough. Chronic cough is a persistent cough that lasts for more than eight weeks and can be caused by a variety of factors, including respiratory infections, asthma, allergies, and acid reflux, but also possibly by an overactive cough reflex. There is a large unmet medical need in novel antitrusive drugs, as current standards of care are ineffective in 30% of patients and only moderately effective in up to 60% of patients. In addition, the current treatments carry risks of serious side effects. Support for using GABA-B PAMs in treatment of chronic cough comes from the clinical evidence of a GABA-B agonist is used off-label in cough patients and from the anatomical evidence that GABA-B receptors are strongly expressed in airways and in the neural pathway regulating cough. Therefore, we believe that GABA-B PAMs could offer superior efficacy in coffee patients. On the next slide, we show that GABA-B PAMs are likely to have a superior vulnerability profile in comparison to the current standards of care and show no taste-related side effects as seen with a newly approved P2X3 inhibitor, Gifamixant. Therefore, it would be an innovative new treatment of chronic cough administered once daily via oral dosing and offering improved efficacy and tolerability with fewer non-responder patients suitable for chronic dosing, therefore significantly improving patient quality of life. We are working with multiple compounds progressing in late clinical candidate selection phase, and we expect to move into IND-enabling studies in 2024 in parallel to delivering compounds to our partner in DVR. I will now pass it back to Robert for an update on our other preclinical programs.

Thanks, Misha. Let me start with an update on our M4-PAM program as a potential novel treatment of schizophrenia and other psychosis. Schizophrenia affects approximately 1% of the world population, and patients have been using the same mechanism of action for the last 50 years with limited efficacy and significant tolerability issues, often leading to treatment discontinuation and relapse. This space is seeing a major breakthrough with the advent of a completely novel approach based on activation of muscarinic M4 acetylcholine receptors. The recent filing of an NDA and acceptance by FDA of xenomyelin, a non-selective M1, M4 agonist, and a peripherally restricted pan-muscarinic antagonist strongly validates the M4 receptor activation approach. In addition, a phase 1B testing of emaraclidine, an M4 positive allostatic modulator developed by Cerevel in schizophrenia patients, showed an antipsychotic effect, paving the way for our M4 positive allostatic modulator program. The mechanism of action of muscarinic M4 acetylcholine receptors allows to reduce striatal dopamine tone without directly blocking the dopamine receptors. the strategy used by current antipsychotic agents. This allows to retain a therapeutic effect without the side effects of typical and atypical antipsychotics. Standard-of-care antipsychotics, as well as non-selective muscarinic agents, suffer from significant side effects, leading to high treatment discontinuation rates. CAR-XT represents a significant step in providing a new treatment of schizophrenia patients but poor selectivity of the pregnancy may result in suboptimal tolerability. Our out-of-state modulation approach is providing many advantages over an agonist approach, in particular with absolute receptor subtype selectivity and without the potential side effects linked to constant receptor activation, such as receptor desensitization and reduced efficacy due to tolerance. The aim of our program is to identify highly selective and brain-penetrant molecules offering potential best-in-class efficacy and tolerability. We are currently working on highly differentiated and novel chemical series identified from our proprietary chemical with our specific allosteric modulation biological assays. We have made great progress in optimizing compounds identifying highly M4 selective compounds, demonstrating an effect in preclinical models of schizophrenia for several lead compounds, and have now entered into clinical candidate selection phase, aiming to identify to enter IND enabling studies in 2024. Onto our M group 2 negative allostatic modulator program for mild neurocognitive disorders associated with Alzheimer's disease, Parkinson's disease, and depression. The program has been awarded a 4 million euros grant to allow identification of one or more drug candidates to advance into IND. Mild neurocognitive disorder, or MNCD, is the stage between expected cognitive decline of normal aging and the more serious decline of dementia. Besides being potentially the early signs of Alzheimer's disease, MNCD is also often experienced by patients suffering from depression. is approximately 15% and augments significantly with age, affecting up to 25% of people aged 80 or more. Interestingly, MNCD is currently viewed as an intervention window for delaying the onset of dementia. mild neurocognitive disorders, Some drugs, such as acetylcholinesterase inhibitors, are being prescribed, but show limited efficacy and come with significant side effects. There is, therefore, a strong unmet medical need for better treatment options. Details by inhibiting presynaptic MGlu2 receptors are negative. Our state modulators will counteract the synaptic deficits observed in MNCD by increasing the excitability of neural circuits involved in cognition. This objective was also followed with positive elastic modulators of AMPA, or ampakines, which pharmaceutical companies tried to develop, but without success. Ampakines seem to induce class-related side effects, and we strongly believe our mGlu2Nam approach will successfully address MNCD without having these side effects. Besides being potentially the early sign of Alzheimer's disease, MNCD is also experienced by patients suffering from depression. Developing mGlu2-Nam offers the exciting opportunity to treat cognitive impairment while also addressing symptoms of depression. Both pro-cognitive and antidepressant effects have been demonstrated in relevant preclinical models with our mGlu2-Nam candidate compound. Our project has been awarded a 4 million Eurograms with one or more drug candidates to enter IND-enabling studies. Eurostars funds highly innovative projects to address unmet needs. Therefore, we see this as a significant validation of our project while providing us with funds for three years. HADx will lead a consortium of highly experienced teams with complementary expertise through a series clinical candidate selection phase before identifying clinical drug candidates to enter IND-enabling studies by end of 2025. In summary, our drug discovery engine has made great progress with multiple drug candidates advancing towards IND-enabling studies. The renewed commitment of our partner DIVIO and the recent award of a €4 million grant are further validation of the quality and productivity of our steric modulation platform. This concludes our prepared remarks on the progress of our R&D programs. I now hand it back to Tim.

Thanks, Robert. I'll now switch to an overview of the financials. Starting with the income statement, we recognized 0.3 million of income in Q3 compared to 0.4 million in Q3 of 2022. The primary source of revenue is research funding from our collaboration with Indivio. In terms of expenses, R&D expenses were $1.8 million in Q3 2023 compared to $2.8 million in Q3 2022. The decrease of $1 million is primarily due to the termination of development in PD-LID in June of 2022. G&A expenses were $1.2 million in Q3 compared to $1.8 million in the same period as 2022. The decrease of 0.6 million is primarily due to reduced share-based service costs and decreased DNO insurance. The finance result is primarily related to foreign exchange gains on US dollar cash deposits and to a lesser extent to interest income. Out of the balance sheet, our assets are primarily held in cash and we completed Q3 with 4.8 million Swiss francs of cash held in Swiss francs and U.S. dollars. Other current assets amount to $1 million and primarily relate to prepaid D&O insurance and retirement benefits, as well as related to our agreement with Indivior. Current liabilities of $1.9 million decreased by $1.4 million compared to December 31, 2022. and primarily relate to our R&D payables and accruals. Non-current liabilities of 0.3 million increased by 2 million compared to December 31st, 2022, and primarily relate to retirement benefit obligations. Now, to summarize, so ADX 71149, Phase II Epilepsy Clinical Study completed recruitment of patients, and top-line results are expected in Q2 of next year. We believe the recommendation of the Independent Review Committee to continue the study is very encouraging and suggests that 149 could be having positive impact on patients. We continue to believe in the value of DIPRA grant and are completing preclinical profiling in post-stroke recovery. In parallel, we are pursuing collaborative arrangements to advance development and look forward to sharing more information in the future. Our preclinical programs continue to make solid progress towards delivering drug candidates for future clinical development and important therapeutic areas in stress-related disorders, chronic cough, cognition, schizophrenia. As a reminder, our portfolio was discovered in-house from our pioneering allostatic modulator drug discovery platform. Consequently, we have significant intellectual property on all programs. We have a track record of securing partnerships at the preclinical stage and supported top-tier investors. We recognize the 2023 stock performance and current market capitalization is very disappointing. However, we are having multiple business discussions across our portfolio and strongly believe that if we are successful in executing our near-term partnering strategy, then our stock price should move to recognize the value of our portfolio. This concludes the presentation. and we will now open the call for questions.

Thank you, dear participants. As a reminder, if you wish to ask a question over the phone, please press star 11 on your telephone keypad and wait for your name to be announced. To withdraw a question, please press star 11 again. Alternatively, you can submit your questions via the webcast.

Please stand by, we will compile the Q&A roster. This will take a few moments.

Now we're going to take our first question over the phone. And it comes from the line of Leonel Delgado from Baader Havel. Your line is open. Please ask your question.

Hi. Thanks for taking my question. So the question is, what can we expect if the epilepsy readout in 2Q24 is positive? So the question is basically, what is the immediate implication for ADEX in 2024? Thank you.

Yes, so thanks for the question. Well, the immediate implications for ADDx. Well, as you know, Janssen is operationally executing the D. They're responsible for financing the study. So ADDx has very little, well, no control over the future development. and we have very limited visibility. However, we believe that the data that's been generated because they've looked at two doses. So should the study be positive, then we would expect the program to be moved forward into a PITL study. But again, we don't have visibility on exactly what the plans of Janssen are with respect to future development.

Thank you. Thank you.

Dear participants, as a reminder, if you wish to ask a question over the phone, please press star 1 1 on your telephone keypad.

Just give us a moment.

At this moment there are no further questions over audio lines and we will proceed to any written questions. And the first question comes from the land of Peter Alec. And the question is, 4 million euros, Eurostars grant, when will the money be paid?

Yeah, so yes, some of that money comes to ADEX and some of that money goes to consortium partners. And we are expecting that money to be or a significant part of money that's allocated to ADHECs to be received by ADHECs quite soon. But we are not providing the details of how that money is split at the current time.

Thank you. The next question comes from the line of Jesse Brodkin. In the IRB review of unblinded data from 149, were efficacy measures unblinded? Also, were any changes in dosage made between cohort one and cohort two?

Yes, so thanks for the question.

Yes, so the independent interim review committee had some very clear guidance from Janssen. And they were given clear guidance that they should recommend to stop the study if they didn't see a certain level of split between active dose and placebo. And also, of course, if they saw any significant safety issues, then they had to recommend stop. Now, the recommendation to continue means that they must have seen at least a signal of efficacy and no significant safety concerns. And that was cohort one. Now, what we know is that cohort two is a higher dose than cohort one. And this is why we are very encouraged by the combination of the recommendation to continue and the fact that cohort two is a higher dose. And now that they have completed recruitment, we are guaranteed of data.

I hope that answers your question.

Thank you. Dear participants, just a quick reminder, if you wish to ask a question over the phone, please press star 11 on your telephone keypad. Alternatively, you're more welcome to submit any questions via the webcast.

The speakers will just give a moment for the last entries.

Thank you, ladies and gentlemen. This brings the main part of our conference for a close. And I would now like to hand it back to Tim Dyer for any closing remarks.

Well, thank you, everyone, for attending the Q3 conference call and the corporate update. We look forward to speaking to you again soon and just wish you a nice end of your day. Thank you. Bye-bye.
