A Trial Of CVX-060, An Anti-Angiogenic COVX-Body, In Combination With Sunitinib In Patients With Advanced Renal Cell Carcinoma
- Registration Number
- NCT00982657
- Lead Sponsor
- Pfizer
- Brief Summary
The safety and tolerability of CVX-060 have been established in the first-in-human clinical trial, CVX-060-101. Thus, this phase Ib/II trial is to assess the safety and pharmacokinetics (PK) profiles of combining CVX-060 with sunitinib in patients with advanced solid tumors, and to subsequently assess the treatment efficacy of the combination treatment, as well as that of sunitinib alone in patients with advanced renal cell carcinoma (mRCC).
- Detailed Description
On 23-Nov-2010, B1131001 (CVX-060-102) was closed to enrollment due to emerging clinical data which led to a re-assessment of the strategic goals of the PF-04856884 program. The study enrolled the Phase 1b portion only. Subsequently, on 25-Oct-2012, due to data safety signals in a separate clinical trial with PF-04856884 (CVX-060), all PF-04856884 studies were discontinued and ongoing patients on B1131001 were permitted to remain on study at a reduced PF-04856884 dose if determined to have been deriving clinical benefit.

- Primary Outcome Measures
Name Time Method Maximum Tolerated Dose (MTD) Baseline up to Cycle 1( Day 1 to Day 42) The MTD was defined as the dose level at which less than or equal to (\<=) 1/6 participants experienced Dose Limiting Toxicity (DLT) during the first cycle of treatment with the next higher dose having \>= 2/6 participants with DLT.
Progression-free Survival (PFS) Baseline tumor progression/clinical deterioration or death (up to 28 days post last dose of study medication) PFS was defined as the time from the first dose date to the first documentation of disease progression or death due to any cause, whichever occurred first.
- Secondary Outcome Measures
Name Time Method Pharmacokinetic Parameters of CVX-060 Pre-dose on Day 1 Cycle 1 ; post-dose on Day 1, 5, 8, 15, 22, 29 Cycle 1 , Day 1 Cycle 2, to Cycle 28 , end of study (7 days post last dose of study medication), follow-up visit (28 days post last dose of study medication) Pharmacokinetic parameters Area under the Curve (AUC), Maximum Observed Serum Concentration (Cmax), Minimum Observed Serum Trough Concentration (Cmin), Clearance (CL), terminal elimination half life (t1/2) were planned to be analyzed.
Number of Participants With Dose-limiting Toxicities (DLT) Baseline up to 28 days post last dose of study medication DLT included grade 4 neutropenia of \>= 3 day duration or with grade 4 neutropenia associated with fever; grade 4 thrombocytopenia for \>= 3 consecutive days; Proteinuria of \>=2 grams (g) per 24 hours; inability to resume to CVX-060 or sunitinib within 14 days of scheduled administration due to treatment related toxicity; any Grade 3 nonhematologic toxicity except nausea, vomiting, and diarrhea; Grade 3 nausea, vomiting, or diarrhea which persists for \>=48 hours; Any \>= Grade 4 non-hematologic toxicity; Any additional hematological or non-hematological toxicity for which dose reduction was required or for which patient was discontinued from the trial.
Serum Angiopoietin-2 (Ang-2) and Plasma Vascular Endothelial Growth Factor (VEGF) Levels Ang-2 (Day 1, 2, 5, 8, 22, 29 Cycle 1, Day 1 Cycle 2 up to Cycle 28); VEGF (Day 1, 8, 15, 22 Cycle 1, Day 1 Cycle 2 up to Cycle 28) Number of Participants With Treatment Emergent Serious Adverse Events (SAEs) and Non-Serious Adverse Events (Non-SAEs) Baseline up to 28 days post last dose of study medication An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to 28 days after last dose that were absent before treatment or that worsened relative to pre treatment state.
Percentage of Participants With Objective Response Baseline up to 7 days post last dose of study medication Percentage 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). Confirmed responses are those that persist on repeat imaging study at least 4 weeks after initial documentation of response. Per RECIST v1.0: CR defined as disappearance of all target lesions and non-target lesions. PR defined as \>= 30% decrease in sum of the longest diameters (LD) of the target lesions taking as a reference the baseline sum LD according to RECIST associated to non-progressive disease response for non target lesions.
Duration of Response Baseline up to 7 days post last dose of study medication Duration of response is defined as the time from the first documentation of objective tumor response to the first documentation of objective tumor progression or death due to any cause, whichever occurs first. Participants last known to be progression free are censored at the date of the last objective disease assessment that verified lack of disease progression.
Number of Participants With Anti- CVX-060 Antibodies Baseline up to 28 days after last CVX-060 dose
