Pfizer PFE announced that the FDA has accepted the supplemental new drug application (sNDA) for Talzenna (talazoparib), an oral PARP inhibitor, in combination with Xtandi (enzalutamide), an androgen receptor pathway inhibitor (ARPI), for an expanded use in prostate cancer.
The sNDA is seeking approval of Talzenna in combination with Xtandi for treating men with homologous recombination repair (HRR) gene-mutated metastatic castration-sensitive prostate cancer (mCSPC), also known as metastatic hormone-sensitive prostate cancer (mHSPC).
With the FDA granting a priority review to the sNDA, a decision from the regulatory body is expected in the last quarter of 2026.
If approved, the sNDA would expand the use of Talzenna plus Xtandi to mCSPC, an earlier stage of the disease. Prostate cancer remains the second most common cancer among men globally.
Talzenna was initially approved in the United States, the EU and several other regions as a monotherapy for adults with deleterious or suspected deleterious gBRCAm HER2-negative locally advanced or metastatic breast cancer. Later, Talzenna, in combination with Xtandi, received FDA approval for treating men with HRR gene-mutated metastatic castration-resistant prostate cancer (mCRPC). The regimen is also approved in the EU for adults with mCRPC in whom chemotherapy is not clinically indicated. The combo is currently authorized in around 60 countries, with indications varying by region.

PFE’s sNDA Based on Phase III TALAPRO-3 Study
The sNDA for the Talzenna plus Xtandi combo in mCSPC was based on data from the phase III TALAPRO-3 study.
Data from the same showed that treatment with Talzenna plus Xtandi reduced the risk of radiographic progression or death by 52% versus placebo plus Xtandi, with consistent benefit seen across patients with BRCA and non-BRCA HRR gene alterations.
The safety profile was similar to the known profiles of each agent, while no new safety signals were reported either.
The phase III TALAPRO-3 study enrolled 599 patients with mCSPC, who had received at most three months of androgen deprivation therapy (chemical or surgical), with or without an approved ARP inhibitor in this setting. Eligible patients in the study were randomized to receive Talzenna 0.5 mg/day plus Xtandi 160 mg/day, or placebo plus Xtandi 160 mg/day.
A regulatory filing seeking approval of Talzenna plus Xtandi in HRR gene-mutated mCSPC is also currently under review in the European Union.
