K-001 Treatment of Advanced Pancreatic Cancer: Clinical Trial of Monotherapy's Tolerability

This study is an open and single-center Phase I clinical research on patients with advanced pancreatic cancer, for evaluating their adverse reactions or tolerance to K-001, so as to determine the safe and reasonable dosage and dosing regimen.

According to past experience to toxicology studies and clinical test, K-001 at a dose of 2700mg/day has a good safety profile for human body. Upon observation, pancreatic cancer patients receiving a medication at 2160mg/day (1080mg BID) have had good therapeutic efficacy, no sign of significant toxicity.

Dosing regimen:

Phase I clinical test: maximum dose of monotherapy at 2700mg/day. Four groups of repeated administration of monotherapy, at least 3 patients for each group.

Group A: 2700mg/d (1350mg BID); Group B: 3240mg/d (1620mg BID); Group C: 3780mg/d (1890mg BID); Group D: 4320mg/d (2160mg BID). Twice a day, to be taken with warm water on an empty stomach; 4 weeks' administration for each group.

In case of severe adverse reactions associated with the test drug, or if half of the participants show adverse reactions at Ⅲ level and above, the test should be terminated. The maximum dosage not causing the above-described situation shall be considered as the maximum tolerated dose or the biologically effective dose. After the test, continuous medication shall be given upon request from patients.
