A Study of TRC105 in Combination With Paclitaxel/Carboplatin and Bevacizumab in Non-Squamous Cell Lung Cancer
Study Details
Study Description
Brief Summary
This is a single center, open-label, nonrandomized, phase 1b study of TRC105 in combination with standard dose treatment in patients with stage IV non-squamous non-small cell lung cancer.
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
| Phase 1 |
Detailed Description
Advanced non-small cell lung cancer has been historically difficult to treat, and novel agents are in dire need.TRC105 has been shown to enhance the anti-angiogenic effect of bevacizumab and may result in more effective angiogenesis inhibition and improved clinical efficacy when combined with bevacizumab and paclitaxel/carboplatin. Participants will be treated with the combination drugs for 6 cycles of therapy (3 weeks per cycle) and may or may not be placed on maintenance therapy depending upon the induction response. Maintenance therapy will continue until there is disease progression, unacceptable toxicity, or patient withdrawal. Blood collections and tumor assessments will be performed throughout the study.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Standard treatment + TRC105 In addition to standard treatment of paclitaxel, carboplatin, and bevacizumab, dosing of TRC105 will begin at 8 mg/kg. However a lower dose level has also been included (6 mg/kg) and will be enrolled if 8 mg/kg is found to exceed the maximum tolerated dose. Following the appropriate pre-medication regimen, the first weekly TRC105 dose (cycle 1 day 8) will be split into two doses whereby 3 mg/kg is administered on cycle 1 day 8 and the balance (e.g., 5 mg/kg for Dose Level 1) is administered on cycle 1 day 11. Beginning with cycle 1 day 15 and thereafter, the full TRC105 dose will be administered intravenously each week during the 21-day cycle. Intra-patient dose reductions are allowed beginning in cycle 2. |
Drug: TRC105
Each patient will be dosed with 6, 8, or 10 mg/kg of TRC105 up to a maximum dose of 850 mg for women and 1,000 mg for men based upon overall body weight.

Outcome Measures
Primary Outcome Measures
- Number of patients with a change in medical management [Baseline up to 28 days after the last cycle]
Adverse events will be graded using the NCI Common Terminology for Criteria for Adverse Events(CTCAE). Incidence, timing, and relatedness of adverse events will be considered as factors in the change of a patient's medical management.
Secondary Outcome Measures
- Measurement of tumor response [Baseline to 3 years]
Radiological tumor assessments from CT or MRI scans will be used to determine an objective response rate.
- Progression-free survival [Baseline to 3 years]
Time to progressive disease
- Number of patients with progression-free survival at 6 months [6 months after the last cycle of treatment completed]
The percentage of patients with progression-free survival in the study
- Overall survival [Baseline to 3 years]
Length of patient survival after starting study treatment
- Measurement of TRC105 concentrations [Collected approximately every 63 days (3 cycles)]
Serum TRC105 concentrations will be measured using validated enzyme-linked immunoassay testing that will assist in analyzing the pharmacokinetics of the drug.
- Measurement of TRC105 anti-product antibodies [Collected approximately every 63 days (3 cycles)]
Anti-product antibody concentrations will be measured using validated enzyme-linked immunoassay testing that will assist in analyzing immunogenicity.
- Identify angiogenic protein biomarkers [Collected approximately every 63 days (3 cycles)]
A central reference lab will conduct biomarker testing that will assist in the analysis of the pharmacodynamics effects on circulating angiogenic biomarkers.
