Trial of Devimistat in Combination With Modified FOLFIRINOX in Patients With Metastatic Adenocarcinoma of the Pancreas

A Multicenter Open-Label Dose Optimization Trial of Devimistat in Combination With Modified FOLFIRINOX in Patients With Metastatic Adenocarcinoma of the Pancreas

This protocol will enroll patients with metastatic pancreatic cancer to receive modified FOLFIRINOX plus devimistat. Patients will be enrolled with 1:1 randomization between Dose Escalation Cohort and Cohort A until required 20 patients have been enrolled on Cohort A following which randomization will end and patients will be enrolled without randomization to Dose Escalation Cohort and then subsequently to Cohort B.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of subjects with dose-limiting toxicity during the first 15 days of devimistat in combination with modified FOLFIRINOX in the dose escalation cohort	The maximum tolerated dose (MTD) will be determined based on dose limiting toxicity	15 days post the start of combination therapy
Median Progression Free Survival (PFS) of devimistat plus modified FOLFIRINOX across all cohorts	The PFS will be defined as time from date of initial treatment to date of radiological or clinical progression (leading to withdrawal from the study treatment), or death from any cause on study treatment, whichever comes first. Follow-up time will be censored at the date of last disease evaluation.	up to 42 months after enrollment

DoR applies to only the patients who achieve either a complete response or a partial response.	up to 42 months after enrollment

To assess pharmacokinetics (AUCinf) of devimistat	The PK parameters of devimistat (and its metabolites, if appropriate), including but not limited to area under the concentration versus time curve from time 0 to infinity (AUCinf)	up to 42 months after enrollment
To assess pharmacokinetics (t1/2) of devimistat	The PK parameters of devimistat (and its metabolites, if appropriate), including but not limited to elimination half-life (t1/2)	up to 42 months after enrollment
