PTX-200 and Carboplatin in Ovarian Cancer

A Phase IA/IB Trial of PTX-200 and Carboplatin in Patients With Platinum-Resistant Recurrent Ovarian Cancer

The main purpose of this study is to determine if Triciribine (TCN) and carboplatin are safe and tolerable when given together, and to determine if this combination of drugs can help people with recurrent ovarian cancer.

Study Overview

• Status: Terminated
• Conditions: Ovarian Cancer
• Intervention / Treatment: Drug: Triciribine; Drug: Carboplatin

Detailed Description

The purpose of this study is to investigate the safety and tolerability, and determine the maximum tolerated dose of triciribine when combined with carboplatin in women with platinum-resistant, recurrent or persistent ovarian cancer. The secondary objectives are to evaluate the clinical activity of carboplatin plus triciribine in women with recurrent/persistent, platinum-resistant ovarian cancer by assessing response rate, progression-free survival, and duration of stable disease.

Description

Inclusion Criteria:

• At least 18 years of age
• Histologically confirmed, measurable or non-measurable, recurrent or persistent, platinum-resistant epithelial ovarian, fallopian tube or primary peritoneal carcinoma. By standard Gynecologic Oncology Group (GOG) criteria, platinum-resistant disease is defined by a disease-free interval of less than 6 months following treatment with a platinum-based regimen, or the progression of disease during platinum-based therapy.
• At least one prior regimen of chemotherapy, with no maximum number of chemotherapy cycles
• 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
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to TCN-PM
• Patients must be disease-free of prior invasive malignancies for >2 years with the exception of basal cell or squamous cell carcinoma of the skin.
• Inability to give informed consent
• Pregnancy
• Corrected QT interval (QTc) prolongation > 450 milliseconds (msec)

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Triciribine & Carboplatin; Phase I/II: 25mg/m^2 Triciribine and Carboplatin AUC 4. Triciribine escalated to 30, 35, 45mg/m^2 if toxicities are not encountered. Phase II: Recommended phase II dose of triciribine and carboplatin.	Drug: Triciribine; Triciribine (15, 25, 30, 35, or 45 mg/m^2) on days 1, 8, 15 every 21 days. To be given as a 60 minute IV infusion.; Other Names: TCN; TCN-PM; triciribine phosphate monohydrate; AKT inhibitor; Drug: Carboplatin; Carboplatin will be administered on day 1 every 21 days, as a 30 minute IV infusion after completion of TCN.; Other Names: Paraplatin®; NSC #241240

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Maximum Tolerated Dose (MTD)	To determine the maximum tolerated dose of TCN-PM when combined with carboplatin in a Phase I clinical trial of biomarker-selected women with platinum-resistant, recurrent or persistent epithelial ovarian, fallopian tube and primary peritoneal cancer (OVCA).	6 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Response Rate (ORR)	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.	2 years
Progression Free Survival (PFS)	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.	2 years
Duration of Stable Disease (SD)	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.	2 years
