Precision Promise is a multi-center, seamless Phase 2/3 platform trial designed to evaluate multiple regimens in metastatic pancreatic cancer.

Primary Objectives

• To compare each investigational arm versus standard of care (SOC) for superiority in overall survival in first and/or second line metastatic ductal adenocarcinoma (metastatic pancreatic cancer) participants and determine which, if any, participants benefit from each investigational arm.

Secondary Objectives

• To determine short and long-term safety signals of each investigational arm in metastatic pancreatic cancer participants vs. SOC.
• To determine progression-free survival (PFS) for each investigational arm vs. SOC.
• To determine rates of overall response, CR, and PR; duration of overall response, CR or PR (whichever occurs first).
• To determine rates of clinical benefit; duration of clinical benefit.

Precision Promise is a multi-center, seamless Phase 2/3 platform trial designed to evaluate multiple regimens in metastatic pancreatic cancer. The goal of the platform is to find effective therapies for pancreatic cancer. The platform will test multiple investigational drugs and combinations compared to standard of care therapy in first and second line metastatic participants. Bayesian response-adaptive randomization will be used to assign participants to arms based on their performance in subtypes of the disease. The primary endpoint is overall survival.

• Participants assigned as males at birth must practice complete abstinence or agree to use a condom (even if he has undergone a successful vasectomy) during sexual contact with persons of childbearing potential while participating in the study, during dose interruptions and for at least 6 months following last dose of study treatment.

• known HIV-infected participants on effective anti-retroviral therapy are eligible if the most recent viral load test performed within six months of screening (based on medical chart review) is negative. If this is not the case, an HIV viral load test should be performed at screening and be negative (i.e., undetectable).

• Known HBV-infected participants are eligible if the most recent viral load test performed within six months of screening (based on medical chart review) is negative. If this is not the case, an HBV viral load test should be performed at screening and be negative (i.e., undetectable).

• Participants with a history of hepatitis C virus (HCV) infection must have been treated and cured. Participants with known HCV infection who are currently on treatment are eligible if the most recent viral load test performed within six months of screening (based on medical chart review) is negative. If this is not the case, an HCV viral load test should be performed at screening and be negative (i.e., undetectable).

• Participants with a history of brain metastases are eligible provided they show evidence of stable lesions (and no new lesions) with no evidence of tumor progression for at least 4 weeks after CNS-directed treatment, as ascertained by clinical examination and brain imaging (MRI or CT) during the screening period. In addition, any neurological symptoms that developed either as a result of the brain metastases or their treatment, must have returned to baseline or resolved. Any steroids administered as part of this therapy must be completed > 7 days prior to the first dose of trial therapy.

• No known leptomeningeal disease.

• Participants with a prior or concurrent malignancy whose natural history does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible. Participants receiving any active therapy for a concurrent secondary malignancy are excluded.

• Participants with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using New York Heart Association Functional Classification. To be eligible for this trial, participants should be Class 2 or better. Class 2 is defined as slight limitation of physical activity, in which ordinary physical activity leads to fatigue, palpitation, or dyspnea; the person is comfortable at rest.
