PF00562271

Pfizer CT.gov Call Center

Phase 1 safety, pharmacokinetics, and pharmacodynamics trial of the focal adhesion kinase (FAK) inhibitor PF-00562271 in patients with positive Positron Emission Tomography \[PET\] scans due to advanced non-hematologic malignancies, including pancreatic, head and neck, and prostatic neoplasms, and patients with other malignancies appropriate for serial biopsy. Screening consists of a Fluorodeoxyglucose Positron Emission Tomography \[FDG-PET\] and tumor imaging, medical history, physical examination, Eastern Cooperative Oncology Group \[ECOG\] performance status, blood draws, a pregnancy test for female patients of childbearing potential. Treatment consists of PF00562271 tablets continued until progression of disease, unacceptable toxicity, or patient request. Evaluations for bioactivity are measured by serial FDG-PET and blood tests for biomarkers related to FAK and PYK2 kinase activities.

Study Of PF-00562271, Including Patients With Pancreatic, Head And Neck, Prostatic Neoplasms

A Phase 1, Open-Label, Dose Escalation Study To Evaluate Safety, Pharmacokinetics And Pharmacodynamics Of PF-00562271 In Patients With Advanced Non-Hematologic Malignancies

At least possibly attributable to study treatment (Tx): Grade (Gr) 4 neutropenia (absolute neutrophil count \[ANC\] \<500 cells/mm\^3) for \>7 days or Gr 3 febrile neutropenia (ANC \<1000/mm\^3, fever ≥38 degrees Celsius; Gr 4 thrombocytopenia (platelets \<25,000 cells/mm\^3); Gr ≥3 non-hematologic toxicity despite adequate medical intervention; Gr ≥3 confirmed prolonged QTc interval (\>500 milliseconds \[msec\]); confirmed cardiac troponin I ≥99 percentile of reference range; Tx related toxicities with failure to receive ≥18 days Tx in 21-day cycle or inability to resume current dose level ≤14 days.

Metabolic response demonstrated in any tumor reduction of ≥15% in tumor FDG standardized uptake value (SUV) in Cycle 1; based on the recommendations of the European Organization for Research and Treatment of Cancer (EORTC) PET Study Group. Participant must have had a baseline PET with at least 1 tumor lesion demonstrating an FDG SUV of ≥5.

Area under the serum concentration time-curve from zero to the last measured concentration; nanograms multiplied by hours per milliliters (ng\*hr/mL).

AUCinf = area under the serum concentration versus time curve from time zero (pre-dose) to extrapolated infinite time (0 - ∞). It is obtained from AUC (0 - t) plus AUC (t - ∞).

Serum decay half-life is the time measured for the serum concentration to decrease by one half.

Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed.

Rac was the ratio of the Day 14 AUC0-tau (0 hour to last dose interval) and AUC during the corresponding time period after the lead-in dose (AUCtau C1.D14/AUCtau C0.D1).

Area under the serum concentration time-curve from zero to the last measured concentration.

Best response recorded from start of treatment (Tx) until disease progression. Complete response: disappearance of all target lesions. Partial response: ≥30% decrease in sum of longest dimensions (LD) of target lesions referencing baseline sum LD. Progressive disease: ≥20% increase in sum LD of target lesions from smallest sum LD recorded since Tx start or appearance of ≥1 new lesions. Stable disease: neither sufficient shrinkage to=PR nor sufficient increase to=PD during first 6 weeks after Tx start referencing smallest sum LD since Tx start.
