Pfizer Says Elrexfio Reduced Progression Risk in Myeloma Trial

The FDA approved the combination of Pfizer's talazoparib (Talzenna) and Astellas Pharma/Pfizer's enzalutamide (Xtandi) for earlier treatment of metastatic prostate cancer with HRR gene mutations. The approval, based on the TALAPRO-3 trial, expands the use of the combination to include patients who have not yet undergone androgen pathway modulation. The trial showed a 52% reduction in risk for radiographic PFS or death compared to placebo plus enzalutamide.

Regeneron presented Phase III data for Libtayo (cemiplimab) in skin cancer, showing a 37% reduction in death risk. Pfizer's STARBOARD trial showed Keytruda triplet therapy improved outcomes in melanoma. Both studies were discussed at ESMO 2026.

Pfizer's elranatamab (Elrexfio) met the primary endpoint of progression-free survival in a phase 3 trial for relapsed/refractory multiple myeloma, showing a 68% 18-month PFS rate. The study compared elranatamab to standard regimens, with safety data consistent with prior findings. Pfizer plans to submit the data to global health authorities. Elranatamab was previously approved for a different patient population in 2023.

Pfizer (PFE) reported positive Phase 3 trial results for ELREXFIO in relapsed or refractory multiple myeloma, meeting its primary endpoint of progression-free survival. The study showed significant risk reduction compared to existing treatments. Pfizer also announced FDA approval for Talzenna in combination with Xtandi for metastatic hormone-sensitive prostate cancer with HRR gene mutations. PFE stock is down slightly in pre-market trading.

Pfizer's ELREXFIO met primary endpoint in Phase 3 trial for multiple myeloma, showing 68% 18-month PFS. The study involved 523 patients. No new safety concerns were found. Pfizer plans regulatory submissions and future data presentations. PFE shares were down 0.34% in pre-market trading.

Pfizer reported positive Phase 3 trial results for ELREXFIO in multiple myeloma, showing 68% of patients alive without disease progression at 18 months. The trial compared ELREXFIO to standard regimens, with Pfizer planning global regulatory submissions. ELREXFIO is already approved in the U.S. for certain patients, and Pfizer is exploring earlier treatment uses.
