Clinical Trial Summary

A Phase 1, Open-label, Dose-Escalation, Safety, Pharmacokinetic and Pharmacodynamic Study of Minnelide™ Capsules given alone or in combination with paclitaxel in patients with Advanced Gastric Cancer.

Description:

Minnelide™ is a water soluble disodium salt variant of triptolide, a diterpenoid, an HSP70 inhibitor. Studies using orthotopic pancreatic cancer cell lines and human xenograft transplants demonstrate that Minnelide™ prevents tumor progression, increases survival, and causes tumor regression.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	To determine any increase of treatment emergent adverse events when Minnelide capsules are given in combination with paclitaxel.	To observe any increase in the number of patients that experience Grade 4 neutropenia lasting = 5 days or Grade 3 or 4 neutropenia with fever and/or infection; Grade 4 thrombocytopenia (or Grade 3 with bleeding); Grade 3 or 4 treatment-related non-hematological toxicity (Grade 3 nausea, vomiting or diarrhea that last > 72 hours despite maximal treatment when Minnelide is given alone and in combination with paclitaxel compared to the incidence with gemcitabine and nab-paclitaxel.	24 months
Secondary	Pharmacokinetics of Minnelide when given with paclitaxel	Area under the concentration curve (AUC) will be determine the exposure of Minnelide	24 months
Secondary	Plasma levels of Minnelide when given with paclitaxel	Maximum plasma concentration (Cmax) will be measured to determine the effect of Minnelide when given with paclitaxel	24 months
