  Purpose

The primary objective of the study was to define the safety profile and maximum tolerated dose (MTD) of sorafenib tablets in combination with carboplatin and paclitaxel chemotherapy in patients with advanced, refractory solid tumors.

The secondary objectives were evaluation of pharmacokinetics (PK) and tumor response of these patients being treated with sorafenib in combination with paclitaxel and carboplatin.

Primary Outcome Measures:
  • Maximum Tolerated Dose (MTD) of Sorafenib in Combination With Paclitaxel and Carboplatin [ Time Frame: 21 days ] [ Designated as safety issue: Yes ]
    MTD was determined by testing increasing doses up to 400 mg twice daily (bid) on dose escalation cohorts 1 to 3 with 3 patients each. MTD reflects highest dose of drug that did not cause an unacceptable side effect (= Dose Limiting Toxicity (DLT) in more than 30% of patients; e.g., hematologic toxicities like CTC Grade 4 Neutropenia in specific conditions, platelets < 25,000 cells/mL; specific non-hematologic/biochemical toxicities CTC Grade 3 or 4; additionally, any toxicity considered by the investigator severe enough was designated a DLT); Common Toxicity Criteria (CTC) Version 2 were used.

  • Participants With Hematological and Biochemical Toxicities [ Time Frame: Start of treatment until death or within 14 days last study drug intake ] [ Designated as safety issue: Yes ]
    Participants are considered at risk for toxicity if participants had a lab measurement for the toxicity >= National Cancer Institute Common Toxicity Criteria (NCI CTC) Grade 3 as defined by the NCI CTC version 2; SGOT: Serum Glutamic-Oxaloacetic Transaminase, SGPT: Serum Glutamic-Pyruvic Transaminase, AST: Aspartate Aminotransferase, ALT: Alanine Aminotransferase.


Secondary Outcome Measures:
  • Tumor Response [ Time Frame: From start of treatment until progression or death occurs assessed every 6 weeks. ] [ Designated as safety issue: No ]
    Tumor Response (= Best Overall Response) of a subject was defined as the best tumor response (confirmed Complete Response (CR), confirmed Partial Response (PR), Stable Disease (SD), or Progressive Disease (PD)) observed during trial period assessed according to the Response Evaluation Criteria in Solid Tumors (RECIST) criteria. CR was defined as disappearance of tumor lesions, PR was defined as a decrease of at least 30% in the sum of tumor lesion sizes, SD was defined as steady state of disease, PD was defined as an increase of at least 20% in the sum of tumor lesions sizes.

  • Area Under the Curve From Time 0 to 12 Hours Post-dose (AUC 0-12) Start From Day 2 of Cycle 1 [ Time Frame: At day 2 in study ] [ Designated as safety issue: No ]
    The AUC is a measure of systemic drug exposure, which is obtained by collecting a series of blood samples and measuring the concentrations of drug in each sample. A plot of concentration vs time after dosing is created, and the area under this curve is calculated by standard methods (eg, trapezoidal rule) to provide a measure of how much drug was in the bloodstream following dosing.

  • Maximum Concentration (CMAX) Start From Day 2 of Cycle 1 [ Time Frame: At day 2 in study ] [ Designated as safety issue: No ]
    Cmax refers to the highest plasma concentration of drug reached after dosing. It is obtained by collecting a series of blood samples after dosing, and analyzing them for drug content by a sensitive and specific analytical method. The highest measured concentration is referred to as the Cmax.

  • Time of Maximum Concentration (TMAX) Start From Day 2 of Cycle 1 [ Time Frame: At day 2 in study ] [ Designated as safety issue: No ]
    Tmax refers to the time after dosing when a drug attains its maximum concentration in the blood. It is obtained by collecting a series of blood samples at various times after dosing, and measuring them for drug content. The time corresponding to the highest measurable concentration (Cmax) is referred to as Tmax.
