Question · Q4 2025
Geoff Meacham questioned the feasibility of extending the dosing interval for 3944 beyond monthly, based on its PK/PD profile, and asked about Pfizer's phase III plans, specifically whether they would be standard metabolic studies or include inflammation/neuropsych indications, or GLP-1 active comparator studies for differentiation.
Answer
Chief Scientific Officer Chris Boshoff confirmed that 3944 is aimed at monthly maintenance, but mentioned another phase I peptide with potential for three-monthly administration. He outlined initial phase III programs (VESPER-4, -5, -6) for patients with and without type 2 diabetes, and monthly dosing, and indicated that beyond cardiovascular and metabolic, Pfizer is exploring other opportunities for differentiation, including combinations with amylin or the GLP antagonist.
