About

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.

Full 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.

Enrollment: 16 patients

• Hemoglobin ≥9.0 g/dL without transfusion support within the past 28 days (erythropoietin or darbepoietin permitted).
• Serum creatinine ≤1.5 times the upper limit of normal or creatinine clearance >30 mL/min by Cockcroft-Gault formula.
• International Normalized Ratio (INR) from 0.8 to 1.2.
• Willingness and ability to consent for self to participate in study.
• Willingness and ability to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.

Exclusion criteria

• Non-small cell lung cancer of squamous histology.
• Prior treatment with TRC105.
• Current treatment on another therapeutic clinical trial.
• Receipt of a small molecule anticancer agent, including an investigational anticancer small molecule, within 14 days of starting study treatment.
• Receipt of a large molecule anticancer agent (e.g., antibody), including an investigational anticancer antibody, within 28 days of starting study treatment.
• No major surgical procedure or significant traumatic injury within 6 weeks prior to study registration, and must have fully recovered from any such procedure; date of surgery (if applicable) or the anticipated need for a major surgical procedure within the next six months. The following are not considered to be major procedures and are permitted up to 7 days before therapy initiation: thoracentesis, paracentesis, port placement, laparoscopy, thorascopy, tube thoracostomy, bronchoscopy, endoscopic ultrasonographic procedures, mediastinoscopy, skin biopsies, incisional biopsies, imaging-guided biopsy for diagnostic purposes, and routine dental procedures.
• Patients who have received wide field radiotherapy ≤28 days (defined as >50% of volume of pelvic bones or equivalent) or limited field radiation for palliation <14 days prior to study registration or those patients who have not recovered adequately from side effects of such therapy.
• Uncontrolled chronic hypertension defined as systolic >150 or diastolic >90 despite optimal therapy (initiation or adjustment of BP medication prior to study entry is allowed provided that the average of 3 BP readings at a visit prior to enrollment is <140/90 mm Hg).
• History of brain involvement with cancer, spinal cord compression, or carcinomatous meningitis, or new evidence of brain or leptomeningeal disease. Patients with radiated or resected lesions are permitted, provided the lesions are fully treated and inactive, patients are asymptomatic, and no steroids have been administered for at least 28 days.
• Angina, myocardial ischemia (MI), symptomatic congestive heart failure, cerebrovascular accident, transient ischemic attack, arterial embolism, pulmonary embolism, percutaneous transluminal coronary angioplasty (PTCA) or coronary artery bypass graft (CABG) within the past 6 months. Deep venous thrombosis within 6 months, unless the patient is anticoagulated without the use of warfarin for at least 2 weeks. In this situation, low molecular weight heparin is preferred.
• Active bleeding or pathologic condition that carries a high risk of bleeding (e.g. hereditary hemorrhagic telangiectasia). Patients who have been uneventfully anticoagulated with low molecular weight heparin are eligible.
• Thrombolytic use (except to maintain i.v. catheters) or anticoagulant use within 10 days prior to first day of study therapy.
• Cardiac dysrhythmias of NCI CTCAE grade ≥2 within the last 28 days.
• Known active viral or nonviral hepatitis or cirrhosis.
• History of hemorrhage or hemoptysis (>½ teaspoon bright red blood) within 3 months of starting study treatment.
• History of peptic ulcer disease or erosive gastritis within the past 3 months, unless treated for the condition and complete resolution has been documented by esophagogastroduodenoscopy (EGD) within 28 days of starting study treatment.
• History of gastrointestinal perforation or fistula in the past 6 months, or while previously on antiangiogenic therapy, unless underlying risk has been resolved (e.g., through surgical resection or repair).
• Known human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) related illness.
• Pregnancy or breastfeeding. Female patients must be surgically sterile (i.e.: hysterectomy) or be postmenopausal, or must agree to use effective contraception during the study and for 3 months following last dose of TRC105. All female patients of reproductive potential must have a negative pregnancy test (serum or urine) within 7 days prior to first dose. Male patients must be surgically sterile or must agree to use effective contraception during the study and for 3 months following last dose of TRC105.
• Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or may interfere with the interpretation of study results.

16 participants in 1 patient group

Standard treatment + TRC105

Experimental group

Description:

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.
