Q & A Highlights

Q: Is R&D spending expected to remain stable, or are there anticipated changes in the coming quarters? A: (W. Matthew Zuga, CFO and Chief Business Officer) R&D spending is expected to increase over the next few quarters, then plateau, and eventually decrease. This quarter's R&D spending was the highest ever for the company and is projected to follow this trend.


Q: What are the plans for the subcutaneous formulation of sabirnetug? A: (Daniel O'Connell, CEO) The immediate focus is on conducting a healthy volunteer study to evaluate the pharmacokinetics (PK) of the subcutaneous formulation. The company is considering various options for future clinical and regulatory paths based on upcoming Phase 1 results.

Q: How does the company view the potential impact of existing Alzheimer's treatments like lecanemab and donanemab on the enrollment for the ALTITUDE study? A: (Daniel O'Connell, CEO) The company is encouraged by the initial phase of the ALTITUDE study and believes that their Phase 1 data will continue to attract interest and drive enrollment, despite the availability of other treatments.

Q: Can the subcutaneous formulation of sabirnetug be integrated into the ongoing ALTITUDE study if the initial human studies are successful? A: (Eric Siemers, Chief Medical Officer) While theoretically possible, logistically integrating the subcutaneous formulation into the ALTITUDE study would be challenging. The plan is to move to patient studies after the healthy volunteer study, potentially replicating some aspects of the ALTITUDE study.

Q: What are the implications of the upcoming FDA Advisory Committee meeting for donanemab for the broader Alzheimer's treatment landscape? A: (Daniel O'Connell, CEO) The meeting will focus on treatment duration and patient stratification, which are significant for future labeling and market development. Approval of donanemab is anticipated to positively influence the Alzheimer's treatment market, supporting infrastructure development and patient access.

Q: What insights have been gained regarding the lack of ARIA-E observed in APOE4 homozygotes and its occurrence only in females from the Phase 1b study? A: (Eric Siemers, Chief Medical Officer) The absence of ARIA-E in APOE4 homozygotes and its occurrence only in females are intriguing findings that are currently not fully understood. These observations will be closely monitored in the Phase 2 study to better understand potential sex differences and antibody efficacy.
