Spots Global Cancer Trial Database for A Phase I/IIa, First Time in Human, Study of GSK2636771 in Subjects With Advanced Solid Tumors With Phosphatase and Tensin Homolog (PTEN) Deficiency

Study Description

Brief Summary: The study consists of a pre-screening period to determine if the subject's tumor has PTEN deficiencies. Subjects then continue into the screening phase for Part 1, 2, or 3, as appropriate. In Part 1, subjects will then receive a single dose of 25 mg. After analysis of 24 hour pharmacokinetic (PK) samples, subjects may receive continuous dosing or receive a single modified dose. In Part 2, subjects will be enrolled and dose escalation will occur in a 3+3 design. Subjects will receive a single dose on Day 1, and then begin continuous daily dosing after collection of a 72-hour PK sample. Additional subjects may be enrolled at lower dose levels for assessment of pharmacodynamic response. In Part 3, up to two tumor-specific expansion cohorts will be enrolled and receive the MTD or BED as defined in Part 2. A minimum of 12 and a maximum of 20 evaluable subjects will be enrolled in each cohort. Interim monitoring for futility will be incorporated after response data from 12 subjects are available. In addition, up to 20 evaluable subjects will be enrolled into Part 3 -Signal-finding Expansion Cohort at the MTD or BED as defined in Part 2. All subjects in all parts/cohorts will receive daily dosing until withdrawal or unacceptable toxicity. All subjects in all parts/cohorts will receive daily dosing until withdrawal or unacceptable toxicity.
