Study of Zoldonrasib (RMC-9805) Plus Daraxonrasib (RMC-6236) Versus Gemcitabine and Nab-Paclitaxel as First-Line Treatment in Metastatic KRAS G12D-Mutated Pancreatic Adenocarcinoma (RASolute 309)

September 1, 2026 updated by: Revolution Medicines, Inc.

A Phase 3, Randomized, Open-Label Study of Zoldonrasib (RMC-9805) Plus Daraxonrasib (RMC-6236) Versus Gemcitabine and Nab-Paclitaxel as First-Line Treatment in Patients With Metastatic KRAS G12D-Mutated Pancreatic Adenocarcinoma

The purpose of this study is to evaluate the efficacy of combination therapy with two investigational RAS(ON) inhibitors (daraxonrasib and zoldonrasib) compared to chemotherapy.

Detailed Description

This is a global, randomized, open-label, Phase 3 study designed to evaluate whether treatment with daraxonrasib plus zoldonrasib will improve progression-free survival and/or overall survival compared with standard gemcitabine and nab-paclitaxel when given as first-line treatment in patients with metastatic KRAS G12D-mutated pancreatic adenocarcinoma.

Patients will be randomized to one of two arms: daraxonrasib + zoldonrasib (Arm A) or gemcitabine and nab-paclitaxel (Arm B).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Overall survival (OS)
Time Frame: Up to approximately 4 years
OS is defined as the time from randomization until death from any cause.
Up to approximately 4 years
Progression free survival (PFS)
Time Frame: Up to approximately 4 years
PFS is defined as the time from randomization until disease progression or death from any cause, whichever occurs first. Progression is per response evaluation criteria in solid tumors (RECIST) v1.1 and as assessed by Investigator.
Up to approximately 4 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incidence of adverse events (AEs)
Time Frame: Up to approximately 4 years
Percentage of patients with AEs as assessed by Common Terminology Criteria for Adverse Events (CTCAE) v5
Up to approximately 4 years
Changes in clinical laboratory test values
Time Frame: Up to approximately 4 years
Number of patients with changes from baseline in clinical laboratory test values
Up to approximately 4 years
Health-related outcome assessed by European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Pancreatic Cancer Module (EORTC QLQ-PAN26) pain scale
Time Frame: Up to approximately 4 years
EORTC QLQ-PAN26 consists of 26 questions relating to disease symptoms, treatment side effects and emotional issues specific to pancreatic cancer. The pancreatic pain subscale assesses abdominal pain, back pain, and pain while lying down. Change in score from baseline in the pain subscale will be assessed with higher scores on the pain subscale indicating more severe pain and worsening function.
Up to approximately 4 years
Quality of life as assessed with European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) global health status score
Time Frame: Up to approximately 4 years
EORTC QLQ-C30 consists of 5 functional scales (physical, role, cognitive, emotional, and social), 9 symptom scales (fatigue, pain, nausea/vomiting, dyspnoea, appetite loss, insomnia, constipation/diarrhea, and financial difficulties), and an overall scale for global health status. It uses a mix of 4-point scales and 7-point scales. Change from baseline in EORTC QLQ-C30 global health status will be assessed. Higher scores on functional scales reflect better functioning, whereas higher scores on symptom scales reflect higher symptom burden.
Up to approximately 4 years
PFS by blinded independent central review (BICR)
Time Frame: Up to approximately 4 years
PFS is defined as the time from randomization until disease progression or death from any cause, whichever occurs first. Progression is assessed per RECIST v1.1 by BICR
Up to approximately 4 years
Objective response rate (ORR)
Time Frame: Up to approximately 4 years
Objective response is defined as partial response (PR) or complete response (CR) per RECIST v1.1, as assessed by the Investigator.
Up to approximately 4 years
Duration of response (DOR)
Time Frame: Up to approximately 4 years
DOR is defined as time from first evidence of objective response (PR or CR) to disease progression or death due to any cause, whichever occurs first, as assessed by the investigator.
Up to approximately 4 years
Changes in vital signs
Time Frame: Up to approximately 4 years
Number of patients with changes from baseline in vital signs
Up to approximately 4 years
Concentration of daraxonrasib and zoldonrasib in Arm A
Time Frame: Up to Cycle 5 Day 1 (each cycle is 28 days)
Pre-dose trough and post-dose blood concentrations of daraxonrasib and zoldonrasib at selected visits.
Up to Cycle 5 Day 1 (each cycle is 28 days)
