Registration Number
NCT05988918
Lead Sponsor
University of Michigan Rogel Cancer Center
Brief Summary

This protocol will enroll patients with pancreatic adenocarcinoma and adenosquamous carcinoma (Cohort 1), gastrointestinal/pancreatic neuroendocrine neoplasms with Ki-67 \> 20% (Cohort 2) and neuroendocrine prostate carcinoma (Cohort 3)). Each cohort will have its own interim analysis after enrollment of 10 patients.

Subjects will be given a one-month (28 day) supply of study drug (ESK981). Subjects will be instructed to take 4 capsules, with or without food, once per day for 5 consecutive calendar days, then take a drug holiday for 2 consecutive days before repeating the 5 days on-2 days off cycle in sets of 4 weeks or 28 calendar days. Subjects will be asked to keep a pill diary noting the date they take their study drug.

Primary Outcome Measures
NameTimeMethod
Progression Free Survival4 months after initiating study drug

Determining efficacy using proportion of patients alive and progression-free at 4 months within each cancer subtype

Secondary Outcome Measures
NameTimeMethod
Overall Survival (OS) within each cancer subtypeup to 18 months from treatment discontinuation

The OS will be defined from the date of treatment to either date of death or censoring and estimated using the product-limit method of Kaplan and Meier. Follow-up time will be censored at the date of last disease evaluation.

Overall Response Rate (ORR) within each cancer subtypeup to 18 months from treatment discontinuation

The ORR will be assessed per RECIST v1.1 criteria (Cohort 1 and 2) or combined RECIST v1.1 + PCWG3 criteria (Cohort 3). Partial or complete response will require confirmation on repeat scan at least 4 weeks from initial radiologic response

Safety and tolerability in each cancer subtypeup to 30 days from treatment discontinuation

Adverse events (AEs) will be defined per the NCI Common Toxicity Criteria for Adverse Events (CTCAE) v5.0.

Median Progression- Free Survival (PFS) within each cancer subtypeup to 18 months from treatment discontinuation

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.

Duration of Response (DoR) within each cancer subtypeup to 18 months from treatment discontinuation

DoR will be measured from the start date of the best response achieved until the date of relapse (i.e., progression). Continuing responders will be right-censored as of the most recent date on which their response status had been assessed. DoR applies to only the patients who achieve either a complete response or a partial response.
