Key Q&A

Q:What is the market opportunity for Avexitide and the baseline population for rapid uptake?

A:The market opportunity for Avexitide includes approximately 160,000 patients with medically important PBH, with 30,000 of those being critical PBH patients who require ER or hospital visits. The management is still working on identifying the first segment of the market to target.

Q:What is the pace of enrollment in the Phase III trial and the expected timeline for data?

A:Enrollment is expected to be completed by the end of the year, with data anticipated in the first half of 2026. Progress towards this goal is on track.

Q:What measures are in place in the Phase III LUCIDITY trial to prevent patients from liberalizing their diet?

A:Participants receive dietary training and are asked to maintain their dietary habits from the run-in period throughout the trial. Compliance is reinforced through site visits and questionnaires. This approach is consistent with prior Phase II and Phase IIb trials.

Q:What are the key determinants for moving the PSP program forward?

A:The decision will be based on clinical endpoints like the PSPRS progression rate, biomarker and imaging data, and a high bar for meaningful improvement.

Q:What is the potential for payers to enforce step edits for non-approved therapies in the PBH market?

A:Management does not anticipate payers enforcing step edits for non-approved therapies like diazoxide and octreotide due to lack of clinical evidence for their effectiveness and low patient satisfaction.

Q:How will variation in treatment duration across patients in the PSP trial impact the analysis?

A:The primary analysis will focus on the 24-week treatment duration for all participants, but data from longer durations will also be considered to understand the impact of extended treatment.

Q:How does the lack of an ICD-10 code affect the PBH market opportunity?

A:Efforts are underway to establish an ICD-10 code. Despite the lack of a code, claims analysis and literature reviews provide consistent prevalence estimates, aligning with Dr. Craig's analysis.

Q:What is the awareness and support level in the PSP patient community?

A:The PSP patient community is highly supportive and enthusiastic about potential treatments, given the lack of approved therapies and the devastating nature of the disease.

Q:What is the impact of Roux-en-Y surgery on the PBH market and the Phase III trial design?

A:Roux-en-Y surgery is a significant contributor to PBH prevalence. The Phase III trial focuses on this population due to robust data, but the drug is expected to work across all bariatric surgery types.

Q:Where are PBH patients typically treated, and what infrastructure is needed to reach them?

A:PBH patients are primarily treated by adult endocrinologists, with some having large patient pools. Early launch efforts will focus on major academic centers, with plans to expand outreach over time.

Q:What are the powering assumptions for the Phase III LUCIDITY trial?

A:The trial is powered to detect a 35% reduction in hypoglycemic events with 90% power, and has even higher power for larger reductions observed in prior trials.

Q:What is the significance of educating PCPs and KOLs about PBH?

A:Educating PCPs and KOLs is crucial for early diagnosis and market development. Endocrinologists are the primary focus for targeted launch efforts.

Q:What is the clinical significance of reducing hypoglycemic events in PBH?

A:Even a single hypoglycemic event is considered clinically significant due to its potential to cause severe, life-altering consequences.

Q:What are the risks of delays in the LUCIDITY trial due to lack of events?

A:Management does not anticipate delays due to lack of events, as the trial design and past data support the expected event rates.

Q:What is the compliance rate for Avexitide, and how does it impact patient adoption?

A:Compliance in past trials was nearly 100%, and patients are motivated to adhere due to the drug's efficacy in reducing traumatic hypoglycemic events.

Q:What feedback has been received from the physician community about PBH and Avexitide?

A:Feedback has been positive, with increased awareness and interest from physicians and patients, as well as strong support from the Endo conference.

Q:What is the impact of new PBH diagnosis guidelines on awareness and diagnosis rates?

A:New guidelines and increased awareness, including PBH's inclusion in endocrinology boards and textbooks, are improving diagnosis rates and understanding among physicians.

Q:What gives confidence in the durability of Avexitide's effect beyond 28 days?

A:While the study is ongoing, past trials and the mechanism of action suggest no tachyphylaxis, supporting confidence in the drug's durability.

Q:Review of Unclear Management Responses

A:Management avoided directly answering questions about the exact first segment of the PBH market to target and the specific path forward for ICD-10 code establishment. Additionally, they provided limited details on the assumptions underlying the first half 2026 timeline for LUCIDITY trial data.
