This Is The First Study Using Escalating Doses Of PF-03758309, An Oral Compound, In Patients With Advanced Solid Tumors

6. října 2015 aktualizováno: Pfizer

Phase 1, Open Label, Dose-Escalation, Safety, Pharmacokinetic And Pharmacodynamic Study Of Single Agent PF-03758309, An Oral PAK4 Inhibitor, In Patients With Advanced Solid Tumors

This is the first study using PF-03758309, an oral compound, in patients with advanced solid tumors. In this study different doses of PF-03758309 will be administered to different groups of patients. The study will assess the compound's safety, the blood levels of PF-03758309 during the treatment and the effect of the compound on the tumor cells.

Detailní popis

The study was prematurely terminated on 26Jul2011 due to the undesirable PK characteristics of PF-03758309 and the lack of an observed dose-response relationship. There were no safety concerns that contributed to the study termination.

Number of Participants With Objective Response
Časové okno: Baseline until the date of first documented progression or discontinuation from the study due to any cause, assessed every 2 months until when the last participant was discontinued due to disease progression in Month 27 of the study
Number of participants with objective response based on assessment of confirmed complete response (CR) or confirmed partial response (PR) according to RECIST. Confirmed CR defined as disappearance of all target lesions. Confirmed PR defined as ≥30% decrease in sum of the longest dimensions (LD) of the target lesions taking as a reference the baseline sum LD according to RECIST. Confirmed responses are those that persist on repeat imaging study ≥4 weeks after initial documentation of response.
Baseline until the date of first documented progression or discontinuation from the study due to any cause, assessed every 2 months until when the last participant was discontinued due to disease progression in Month 27 of the study
Time to Tumor Progression (TTP)
Časové okno: Baseline until the date of first documented progression or discontinuation from the study due to any cause, assessed every 2 months until when the last participant was discontinued due to disease progression in Month 27 of the study
Time in weeks from start of study treatment to first documentation of objective tumor progression or death due to cancer, whichever comes first. TTP was calculated as (first event date minus the date of first dose of study medication plus 1) divided by 7. Tumor progression was determined from oncologic assessment data (where data meet the criteria for progressive disease [PD])
Baseline until the date of first documented progression or discontinuation from the study due to any cause, assessed every 2 months until when the last participant was discontinued due to disease progression in Month 27 of the study
Duration of Response
Časové okno: Baseline until the date of first documented progression or discontinuation from the study due to any cause, assessed every 2 months until when the last participant was discontinued due to disease progression in Month 27 of the study
Time in weeks from the first documentation of objective tumor response to objective tumor progression or death due to any cancer. Duration of tumor response was calculated as (the date of the first documentation of objective tumor progression or death due to cancer minus the date of the first CR or PR that was subsequently confirmed plus 1) divided by 7. DR was calculated for the subgroup of participants with a confirmed objective tumor response.
Baseline until the date of first documented progression or discontinuation from the study due to any cause, assessed every 2 months until when the last participant was discontinued due to disease progression in Month 27 of the study
