NEW YORK, April 21, 2026 (GLOBE NEWSWIRE) -- Immuneering Corporation (Nasdaq: IMRX), a late-stage clinical oncology company focused on keeping cancer patients alive and helping them thrive, today announced that updated data from the Phase 2a clinical trial evaluating atebimetinib (IMM-1-104) in combination with modified gemcitabine/nab-paclitaxel (mGnP) in first-line pancreatic cancer patients will be presented as an oral presentation at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting, taking place May 29 – June 2, 2026, in Chicago, IL.
The oral presentation will highlight data from an expanded cohort totaling 55 first-line patients, which includes the initial cohort of 34 patients that the company previously reported plus an additional 21 patients.
“We are excited to present new survival data from an expanded cohort of 55 first-line pancreatic cancer patients treated with atebimetinib in combination with mGnP in an oral presentation at ASCO,” said Ben Zeskind, Ph.D., CEO of Immuneering. “Atebimetinib was designed with three distinct mechanisms to promote survival: shrinking tumors durably, preserving body mass, and maximizing tolerability. We believe these mechanisms have the potential to both yield the best survival in the first-line setting, and to give patients the best chance of reaching and benefitting from second-line treatment. We look forward to sharing this updated dataset in first-line pancreatic cancer patients as we pursue our mission to help patients survive and thrive.”
Oral Presentation Details:
Title: Results from a phase 2a study of atebimetinib in combination with mGnP in advanced or metastatic pancreatic cancer
Session Type/Title: Rapid Oral Abstract Session – Gastrointestinal Cancer – Gastroesophageal, Pancreatic, and Hepatobiliary
Abstract Number: 4013
Date and Time: June 1, 2026, 1:15 p.m. – 2:45 p.m. CDT
Presenter: Peter Vu, MD, MHA
About Immuneering
Immuneering is a late-stage clinical oncology company focused on keeping cancer patients alive and helping them thrive. The Company is developing an entirely new category of cancer medicines, Deep Cyclic Inhibitors, designed to improve overall survival by three mechanisms: shrinking tumors durably with less resistance, preserving body mass by countering cachexia, and minimizing side effects to maximize performance status and combinability. Immuneering’s lead product candidate, atebimetinib, is an oral, once-daily Deep Cyclic Inhibitor of MEK, designed to improve survival across many cancer indications, including MAPK pathway-driven tumors such as pancreatic cancer. The company expects to dose the first patient in mid-2026 in MAPKeeper 301, a globally randomized pivotal Phase 3 trial evaluating atebimetinib in combination with chemotherapy in first-line pancreatic cancer patients. The Company’s development pipeline also includes additional combination opportunities and early-stage programs. For more information, please visit www.immuneering.com.
