Precision PromiseSM is a multi-center, seamless Phase 2/3 platform trial designed to evaluate multiple regimens in metastatic pancreatic cancer.
- To compare each investigational arm versus standard of care (SOC) for superiority in overall survival in 1st and/or 2nd line metastatic pancreatic cancer patients and determine which, if any, patients benefit from each investigational arm.
- To determine short and long-term safety signals of each investigational arm in pancreatic cancer patients vs. SOC.
- To determine progression-free survival (PFS) for each investigational arm vs. SOC.
- Rates of overall response, CR, and PR; duration of overall response, CR or PR (whichever occurs first).
- Rate 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 rapidly and efficiently test multiple novel drugs and combinations compared to standard of care therapy in first and second metastatic patients. Bayesian response-adaptive randomization will be used to assign patients to arms based on their performance in subtypes of the disease. The primary endpoint is overall survival.
- Drug: Dose
- Nab-paclitaxel is infused over 30-40 min on days 1, 8, 15 of each 28-day cycle. Gemcitabine is infused over 30 min, immediately after completion of nab-paclitaxel infusion, on days 1, 8, 15 of each 28-day cycle If one of the chemotherapy medications is held, the other study medications may be given. Doses should be re-adjusted if the subject’s BSA changes by +/- >10%. If the subject’s BSA changes by <10%, no adjustment is necessary unless the site has a standard procedure to adjust doses based upon current BSA according to institutional guidelines.
- Drug: Dose -SM-88
- 460 mg (2 capsules) twice daily of a 28-day cycle along with the administration of methoxsalen, phenytoin and sirolimus.
- Drug: Dose -mFOLFIRINOX
- The following are recommended parameters for infusion timing and sequence, although institutional variation in the administration of the regimen are permitted, as long as drug dosing and modification guidelines are followed. Oxaliplatin and leucovorin are administered concurrently over 30-120 minutes, followed by irinotecan over 30-90 minutes, followed by the infusion of 5-flurouracil. If one of the chemotherapy medications is held, the other study medications may be given. Doses should be re-adjusted if the subject’s BSA changes by +/- >10%. If the subject’s BSA changes by <10%, no adjustment is necessary unless the site has a standard procedure to adjust doses based upon current BSA according to institutional guidelines.
Arms, Groups and Cohorts
- Other: Gemcitabine combined with nab-paclitaxel
- The following are recommended parameters for infusion timing and sequence, although institutional variation in the administration of the regimen are permitted as long as drug dosing and modification guidelines are followed.
- Experimental: SM-88
- 460 mg (2 capsules) twice daily of a 28-day cycle along with the administration of methoxsalen, phenytoin and sirolimus. All four agents (SM-88, methoxsalen, phenytoin, and sirolimus) should be dosed with approximately 240 mL (8 fl. oz.) of water in the morning. All four agents should be taken together consistently. SM-88 used with MPS should ideally be taken approximately 1 hour before or 2 hours after a meal.
- Other: mFOLFIRINOX
- Oxaliplatin 85 mg/m2, Leucovorin 400 mg/m2, Irinotecan 150 mg/m2, 5-Fluorouracil 2400 mg/m2 46-48 hour infusion
Clinical Trial Outcome Measures
- Overall Survival
- Time Frame: 0 weeks
- Overall survival (OS) is defined from the time of initiation of treatment until death due to any cause. Subjects still alive at the time of an analysis will be considered censored at their date of last contact.
- Progression free survival (PFS)
- Time Frame: From initiation of therapy to clinically determined disease progression or death due to any cause, whichever came first, assessed up to 24 months.
- PFS will be presented with probability that the hazard ratio is less than 1.0 as well as the corresponding Kaplan-Meier curves and the log-rank test for the comparison with controls.
- Performance Status
- Time Frame: From screening through study completion, an average of 2 years.
- Changes in Performance Status will be evaluated using the Eastern Cooperative Oncology Group (ECOG) Performance Status, where the highest value is 0 (patient is fully active) and the lowest value is 5 (patient is deceased).
- Overall Response Rate (ORR)
- Time Frame: From initiation of treatment to clinically determined tumor size reduction for a minimum of 4 weeks
- ORR is defined as the portion of subjects on an arm with a tumor size reduction of at least 30%.
- Duration of Overall Response Rate (ORR)
- Time Frame: From date of first occurrence of a documented objective response to date of clinically determined disease progression or death due to any cause, whichever came first, assessed up to 24 months.
- Duration of ORR is defined as the time from the date of response to the date of clinically determined disease progression or death due to any cause.
- Duration of Clinical Benefit
- Time Frame: From screening through last dose of therapy, assessed up to 24 months.
- Duration of Clinical Benefit will be evaluated using a composite of measures including patient reported outcomes (PROs), supportive care regimens, and disease status.
