Phase 1
Completed
Conditions
Neoplasms
Interventions
Drug: PF-03732010
Registration Number
NCT00557505
Lead Sponsor
Pfizer
Brief Summary

P-cadherin may play a part in tumor growth; PF-03732010 is a new drug that inhibits P-cadherin. This study will test how well the drug is tolerated, and what effects there might be. Blood will also be taken to measure the amount of drug in blood.

Primary Outcome Measures
NameTimeMethod
Maximum Tolerated Dose (MTD)Baseline up to end of treatment (EOT) or withdrawal assessed up to Day 7 of last cycle
Recommended Phase-2 Dose (RP2D)Baseline up to EOT or withdrawal assessed up to Day 7 of last cycle
Secondary Outcome Measures
NameTimeMethod
Area Under the Curve From Time Zero to Last Quantifiable Concentration [AUC (0-28 Day)]0 (pre-dose), 0.5, 1, 1.5, 2, 5, 10, 24 hrs after the start of infusion of first dose, Day 3, 5, 8, 11 of cycle 1; pre-dose and 1 hr after start of infusion in every other cycle starting from cycle 2 up to Week 4, 8 and 12 after last dose or withdrawal

AUC (0-28 day)= Area under the plasma concentration versus time curve from time zero (pre-dose) to time of last quantifiable concentration (0-28 day).

Time to Reach Maximum Observed Serum Concentration (Tmax)0 (pre-dose), 0.5, 1, 1.5, 2, 5, 10, 24 hrs after the start of infusion of first dose, Day 3, 5, 8, 11 of cycle 1; pre-dose and 1 hr after start of infusion in every other cycle starting from cycle 2 up to Week 4, 8 and 12 after last dose or withdrawal
Minimum Observed Serum Trough Concentration (Cmin)0 (pre-dose), 0.5, 1, 1.5, 2, 5, 10, 24 hrs after the start of infusion of first dose, Day 3, 5, 8, 11 of cycle 1; pre-dose and 1 hr after start of infusion in every other cycle starting from cycle 2 up to Week 4, 8 and 12 after last dose or withdrawal
Maximum Observed Serum Concentration (Cmax)0 (pre-dose), 0.5, 1, 1.5, 2, 5, 10, 24 hrs after the start of infusion of first dose, Day 3, 5, 8, 11 of cycle 1; pre-dose and 1 hr after start of infusion in every other cycle starting from cycle 2 up to Week 4, 8 and 12 after last dose or withdrawal
Area Under the Curve From Time Zero to Last Quantifiable Concentration [AUC (0-14 Day)]0 (pre-dose), 0.5, 1, 1.5, 2, 5, 10, 24 hrs after the start of infusion of first dose, Day 3, 5, 8, 11 of cycle 1; pre-dose and 1 hr after start of infusion in every other cycle starting from cycle 2 up to Week 4, 8 and 12 after last dose or withdrawal

AUC (0-14)= Area under the plasma concentration versus time curve from time zero (pre-dose) to time of last quantifiable concentration (0-14 day).

Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)0 (pre-dose), 0.5, 1, 1.5, 2, 5, 10, 24 hrs after the start of infusion of first dose, Day 3, 5, 8, 11 of cycle 1; pre-dose and 1 hr after start of infusion in every other cycle starting from cycle 2 up to Week 4, 8 and 12 after last dose or withdrawal

Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast).

Clearance (CL)0 (pre-dose), 0.5, 1, 1.5, 2, 5, 10, 24 hrs after the start of infusion of first dose, Day 3, 5, 8, 11 of cycle 1; pre-dose and 1 hr after start of infusion in every other cycle starting from cycle 2 up to Week 4, 8 and 12 after last dose or withdrawal

Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

Apparent Volume of Distribution (Vd)0 (pre-dose), 0.5, 1, 1.5, 2, 5, 10, 24 hrs after the start of infusion of first dose, Day 3, 5, 8, 11 of cycle 1; pre-dose and 1 hr after start of infusion in every other cycle starting from cycle 2 up to Week 4, 8 and 12 after last dose or withdrawal

Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of a drug.

Number of Participants With Objective Response of Complete Response or Partial ResponseBaseline to disease progression or 4 weeks after the first dose and then every 6 weeks up to Week 37

Number of participants with objective response based assessment of confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST). CR are those that persist on repeat imaging study at least 4 weeks after initial documentation of response. PR are those with at least 30 percent decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions.
