Atebimetinib plus gemcitabine and nab‑paclitaxel as first‑line treatment for metastatic pancreatic cancer
Official title: A Phase 3 Randomized, Open-Label Study of Atebimetinib in Combination With the Modified Gemcitabine and Nab-Paclitaxel Regimen Versus the Standard Gemcitabine and Nab-Paclitaxel Regimen for the Treatment of Patients With Metastatic Pancreatic Ductal Pancreatic Adenocarcinoma Cancer (MAPKeeper 301)
Run by Immuneering Corporation · NCT07562152 · Data updated 2026-11-12
This trial will test whether adding the MAPK pathway drug atebimetinib to gemcitabine and nab‑paclitaxel helps people with newly diagnosed metastatic pancreatic ductal adenocarcinoma live longer.

Is this trial a fit for you?
✓Likely a good fit
Adults (≥18) with newly diagnosed, treatment‑naive metastatic pancreatic ductal adenocarcinoma, ECOG 0–1, measurable disease, and adequate organ function are the intended candidates.
✕Probably not a fit
Patients with non‑adenocarcinoma pancreatic tumors (for example neuroendocrine or acinar histology), only locally advanced disease, inability to swallow oral medication, or untreated symptomatic CNS metastases are excluded and unlikely to benefit from this protocol.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a global, randomized, open‑label Phase 3 study that assigns patients to either atebimetinib combined with a modified schedule of gemcitabine and nab‑paclitaxel or to standard gemcitabine and nab‑paclitaxel as first‑line therapy. Eligible participants are adults with treatment‑naive metastatic pancreatic ductal adenocarcinoma, ECOG performance status 0–1, and measurable disease per RECIST v1.1. The primary outcome is overall survival, with safety and other efficacy endpoints monitored throughout treatment. The study is being run at multiple City of Hope sites in the United States.
Why it matters
Potential benefit: If successful, the combination could extend overall survival compared with the current standard gemcitabine/nab‑paclitaxel regimen.
How similar studies have gone: Previous efforts to target the MAPK/MEK pathway in pancreatic cancer have shown limited success, so combining a MEK pathway agent with frontline chemotherapy is a relatively novel approach that is not yet proven in Phase 3.
