1 An Open Label, Multicenter Phase I Study Of Selective Cyclin Dependent Kinase Inhibitor P1446A-05 In Subjects With Advanced Refractory Malignancies
This is a phase I study of a novel compound P1446A-05. Aim of this study is to identify the the recommended phase II dose of the drug and to determine the nature of adverse effects associated with the drug. P1446A-05 capsules will be given continuously (28 days in each 28 day cycle) to patients suffering from advanced malignancies with no effective treatment available. The dose of the study agent will be lower i.e. 75 mg per day for initial patients. If this dose is found safe, higher dose will be administered to next set of (three to six) patients. This will continued till the safest and best dose is identified. Treatment will be given for 4 cycles and continued further if found effective. Dose schedule may be modified to introduce treatment holiday,if frequent adverse effects are seen on continuous administration.

Primary Outcomes
Description: The study will be conducted in two phases- Phase I (Dose escalation phase), and Extension phase. In the Dose escalation' phase patients will be co-administered P1446A-05 (150, 250, 350 mg qd) and vemurafenib (720, 960 mg bid) in a cohort of three to six patients on a 28-day cycle, until the occurrence of disease progression or unacceptable toxicity. Escalation to the next higher dose during the dose escalation phase will depend upon demonstrated safety in the previous dose group. The maximum tolerated dose (MTD) of P1446A-05 and vemurafenib co-administered will be determined. In the 'Extension' phase, sixty patients with BRAF V600E/K mutations (forty patients naïve to selective BRAF inhibitor therapy, and twenty progressing on selective BRAF inhibitor therapy) will be treated at the MTD on a 28-day cycle, until the occurrence of disease progression or unacceptable toxicity to determine efficacy of the co-administration.
