PTX-200 and Carboplatin in Ovarian Cancer

• Overall Response Rate (ORR) [ Time Frame: 2 years ]

  The best overall response is the best time point response recorded from the start of the treatment until disease progression/recurrence (taking as reference for progressive disease the smallest sum recorded since baseline).

  Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10mm.

  Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.

  Response and progression will be evaluated using Response Evaluation Criteria in Solid Tumors (RECIST version 1-1). Changes in the largest diameter (unidimensional measurement) of the tumor lesions and the shortest diameter in the case of malignant lymph nodes are used in the RECIST criteria.

• Progression Free Survival (PFS) [ Time Frame: 2 years ]

  Progression-Free Survival (PFS) is defined as the duration of time from study entry to time of progression or death, whichever occurs first.

  Progressive Disease (PD): At least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progressions).

  Response and progression will be evaluated using Response Evaluation Criteria in Solid Tumors (RECIST version 1-1). Changes in the largest diameter (unidimensional measurement) of the tumor lesions and the shortest diameter in the case of malignant lymph nodes are used in the RECIST criteria.

• Duration of Stable Disease (SD) [ Time Frame: 2 years ]

  Stable Disease (SD): Neither sufficient shrinkage to qualify for Partial Response (PR) nor sufficient increase to qualify for Progressive Disease (PD), taking as reference the smallest sum diameters while on study.

  Response and progression will be evaluated using Response Evaluation Criteria in Solid Tumors (RECIST version 1-1). Changes in the largest diameter (unidimensional measurement) of the tumor lesions and the shortest diameter in the case of malignant lymph nodes are used in the RECIST criteria.

• A serum creatinine ≤ 1.5 mg% obtained ≤ 2 weeks prior to entry
• Adequate hematologic reserve obtained ≤ 2 weeks prior to entry: leukocytes ≥ 3,000 mm^3; absolute neutrophil count ≥ 1500 mm^3; platelets ≥ 100,000 mm^3
• Adequate hepatocellular function: aspartate aminotransferase (AST) and alanine transaminase (ALT) ≤ 3x upper limit of normal within institutional limits; bilirubin ≤ 1.5 mg/dl
• Gynecologic Oncology Group (GOG) Performance Status of 0, 1, or 2
• Life expectancy of at least 90 days
• The patient should be off chemotherapy, biologic therapy and radiation for 28 days.
• Neuropathy (sensory and motor) less than or equal to grade 1 per Common Toxicity Criteria (CTC) version 4

Exclusion Criteria:

• Prior TCN-PM therapy
