Key Q&A
Q:What learnings have been gained from the execution of the clinical trial so far, specifically regarding the recruitment and run-in period?
A:The inclusion criteria and study design were informed by prior Phase II trials, which showed statistically significant and clinically meaningful reductions in hypoglycemic events. Recruitment has been successful, and the study underscores the unmet medical need for PBH treatment. PBH is a large orphan condition with no approved treatments, and the mainstay of care is medical nutrition therapy, which is insufficient to prevent events.
Q:Why is the placebo rate assumption in the Phase III study unusually low, and how does it compare to Phase II?
A:The Phase III study is designed with conservative assumptions to ensure adequate power. Based on prior data, including Phase II trials and work from Zealand Pharma, there is little expectation of a placebo response. The design aims to account for all variables to ensure robust results.
Q:What are the learnings from LUCIDITY in the context of commercial preparation, and how many patients are enrolled in the OLE?
A:LUCIDITY highlights the unmet need and opportunity in PBH treatment. Market research estimates a prevalence of 160,000 PBH patients, with numbers expected to grow. The study has corroborated claims data and identified key treatment centers. Regarding the OLE, recruitment is complete, and participants are rolling over, but specific enrollment numbers are not disclosed.
Q:How has claims data been validated, and what does it reveal about patient distribution across treatment centers?
A:Claims data has been pressure-tested across various types of centers to validate epidemiology and patient distribution. The data suggests a mix of centers with concentrated pools of patients and others with fewer cases, consistent with orphan disease patterns. This informs commercial strategies and deployment plans.
Q:Were there nonresponders or suboptimal responders in the avexitide Phase IIb trial, and how did this impact results?
A:The Phase IIb trial showed a strong effect with a 66% reduction in hypoglycemic events and a median event rate of 0. While there was variability in responses, the effect was consistent across the cohort, as evidenced by the strong p-value (<0.001).
Q:What is the significance of the 30,000 critical PBH patients identified in market research, and how does this influence commercial strategy?
A:Physicians view all PBH events as medical emergencies, not just those leading to ER visits. While critical patients are a priority, the broader PBH population also represents a significant unmet need. This informs a comprehensive go-to-market strategy.
Q:What magnitude of reduction in hypoglycemic episodes is considered meaningful by physicians and payers?
A:Physicians and patients consider any reduction in hypoglycemic events meaningful, as each event is a medical emergency. Statistical significance in the LUCIDITY trial will be important for regulatory and commercial success.
Q:Will baseline characteristics from LUCIDITY be shared before the Q3 readout?
A:The decision is still under consideration, but the study's quick 16-week turnaround may limit the sharing of baseline characteristics before the Q3 readout.
Q:What is the timeline and potential for the 0318 compound in lifecycle management and other endocrine indications?
A:The 0318 compound is being advanced quickly, with potential applications in other endocrine conditions beyond PBH. These include hypoglycemic events following various gastrointestinal surgeries, with opportunities in the U.S., Europe, and Asia.
Q:How does the current use of acarbose in PBH treatment compare to the potential of avexitide?
A:Acarbose is not FDA-approved for PBH and is poorly tolerated, with limited efficacy in addressing the root cause of PBH. Avexitide targets the hyper-reactive GLP-1 response, offering a more effective solution.
Q:What is the significance of an ICD-10 code for PBH, and how does it impact avexitide?
A:An ICD-10 code would increase awareness and facilitate identification of PBH patients in claims databases. While not necessary for reimbursement, it underscores the growing recognition of PBH as a significant medical condition.
Q:What are the expectations for event levels (Level 2 vs. Level 3) in the LUCIDITY trial?
A:Level 2 events are symptomatic and risky, often leading to Level 3 events, which are incapacitating. Previous studies showed slightly more Level 2 events, but both levels are critical for assessing treatment efficacy.
Q:How were dietary factors addressed in the design of the LUCIDITY trial?
A:Participants receive detailed training and guidelines to maintain dietary consistency, a key factor replicated from successful Phase II studies. Participants are highly motivated to adhere to these guidelines.
Q:Does GLP-1 receptor blockade remain effective with increased carbohydrate intake?
A:Yes, avexitide has shown robust effects even with significant carbohydrate loads, as demonstrated in Phase I studies where it prevented hypoglycemia after large glucose boluses.
Q:What is the tolerability profile of avexitide, and what are the key considerations for the Gubra asset?
A:Avexitide has an excellent tolerability profile with mild injection site reactions and rare antidrug antibodies. The Gubra asset aims to maintain these attributes while optimizing manufacturability and efficacy.
Q:Review of Unclear Management Responses
A:Management avoided providing specific details on the number of patients enrolled in the OLE, baseline characteristics from LUCIDITY before the Q3 readout, and the exact number of treatment centers validated through claims data. Additionally, they deferred detailed discussions on commercial strategies and lifecycle management timelines for the 0318 compound.
