Study of Daraxonrasib and Daraxonrasib + GnP as First-line Treatment in Patients With Metastatic Pancreatic Adenocarcinoma (RASolute 303)

September 30, 2026 updated by: Revolution Medicines, Inc.

RASolute 303: A Phase 3 Global, Multicenter, Open-label, Randomized, 3-Arm Study of Daraxonrasib Monotherapy or Daraxonrasib Plus Gemcitabine and Nab-paclitaxel Versus Gemcitabine and Nab-paclitaxel as a First-Line Treatment for Patients With Metastatic Pancreatic Adenocarcinoma

The purpose of this study is to evaluate the safety and efficacy of an investigational RAS(ON) inhibitor administered as monotherapy or in combination with chemotherapy, compared with standard of care (SOC) chemotherapy alone.

Detailed Description

This is a global, randomized, open-label, Phase 3 study designed to evaluate whether treatment with daraxonrasib monotherapy or daraxonrasib plus gemcitabine and nab-paclitaxel 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 pancreatic adenocarcinoma.

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

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Progression free survival (PFS)
Time Frame: Up to approximately 2 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 2 years
Overall survival (OS)
Time Frame: Up to approximately 2 years

OS is defined as the time from randomization until death from any cause.

Up to approximately 2 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Objective response rate (ORR)
Time Frame: Up to approximately 2 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 2 years
Duration of response (DOR)
Time Frame: Up to approximately 2 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 2 years
Concentration of daraxonrasib in Arm A and B
Time Frame: Up to Cycle 5 Day 1 (each cycle is 28 days)

Pre-dose trough and post-dose blood concentrations of daraxonrasib at selected visits.

Up to Cycle 5 Day 1 (each cycle is 28 days)
Health-related outcome assessed by European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Pancreatic Cancer Module (EORTC QLQ-PAN26)
Time Frame: Up to approximately 2 years

EORTC QLQ-PAN26 consists of 26 items assessing patient-reported health-related quality of life, including symptoms and impacts. Change from baseline in the pain subscale scores will be evaluated, with higher scores indicating greater symptom burden.

Up to approximately 2 years
Quality of life as assessed with European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30)
Time Frame: Up to approximately 2 years

EORTC QLQ-C30 is a 30-item cancer-specific instrument consisting of 5 functional scales (physical, role, cognitive, emotional, and social), 9 symptom scales (fatigue, pain, nausea/vomiting, dyspnea, appetite loss, insomnia, constipation/diarrhea, and financial difficulties), and an overall scale for global health status. Change from baseline in EORTC QLQ-C30 global health status will be assessed, with higher scores reflecting better functioning.

Up to approximately 2 years
Incidence of adverse events (AEs)
Time Frame: Up to approximately 2 years

Percentage of patients with AEs as assessed by Common Terminology Criteria for Adverse Events (CTCAE) v5

Up to approximately 2 years
Changes in vital signs
Time Frame: Up to approximately 2 years

Number of patients with clinically significant changes in vital signs

Up to approximately 2 years
Changes in clinical laboratory test values
Time Frame: Up to approximately 2 years

Number of patients with changes from baseline in clinical laboratory test values

Up to approximately 2 years
