Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 50 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2010-09-30
• Study Completion Date: 2016-09-30

Brief Summary

The purpose of this study is to test the safety and determine the optimal dose of a new drug, demcizumab (OMP-21M18), when given in combination with carboplatin and pemetrexed, a standard drug treatment regimen for non-squamous non-small cell lung cancer (NSCLC). Participants must not have received prior chemotherapy for their NSCLC. Demcizumab is a humanized monoclonal antibody (a protein made in the laboratory) developed to target cancer stem cells. The way the body handles demcizumab will also be investigated.

Up to 50 subjects will be enrolled at up to 8 centers in Australia, New Zealand, and Spain. Up to 28 days (4 weeks) prior to treatment you will undergo testing to determine your eligibility to take part in this study, and then if enrolled in the study you will receive intravenous (in the vein) infusions of the demcizumab, carboplatin, and pemetrexed administered on the same day, every 21 days for 4 cycles, or until it has been shown that your cancer has progressed. If your physician decides to delay treatment with one of the agents due to side effects, the other agents may still be administered as scheduled. After 4 cycles, if you have stable or improved disease, you will continue to receive pemetrexed once every 21 days as maintenance therapy. You will undergo assessments every 8 weeks to determine the status of your disease.

Detailed Description

Current cancer therapies often produce an initial reduction in tumour size but may not have longterm benefits. One possible explanation for this is the presence of cancer cells known as cancer stem cells. Cancer stem cells represent a small part of the tumour but are believed to be responsible for much of the growth and spread of the cancer. They may also be more resistant to traditional therapy, such as chemotherapy and radiation therapy.

Up to 50 subjects will be enrolled at up to 8 centers in Australia, New Zealand, and Spain. Up to 28 days (4 weeks) prior to treatment you will undergo testing to determine your eligibility to take part in this study, and then if enrolled in the study you will receive intravenous (in the vein) infusions of the demcizumab, carboplatin, and pemetrexed administered on the same day, every 21 days for 4 cycles, or until it has been shown that your cancer has progressed. If your physician decides to delay treatment with one of the agents due to side effects, the other agents may still be administered as scheduled. After 4 cycles, if you have stable or improved disease, you will continue to receive pemetrexed once every 21 days as maintenance therapy. You will undergo assessments every 8 weeks to determine the status of your disease.

In addition to routine testing of blood and urine (for complete blood counts with differential and platelets, coagulation studies to determine how quickly your blood is clotting; serum chemistries; B-type natriuretic peptide [BNP] and Troponin I, which indicate how well your heart if working; creatinine clearance to measure your kidney function and urinalysis), special tests will be performed during the study at specific time points.

In addition, you will have an ECG and doppler echocardiogram performed during screening, then every 28 days on study and at treatment termination. Your Doppler echocardiograms may be sent to a Cardiologist at another hospital who may perform a central read on some of the doppler echocardiograms in this study. Finally, you will have a head CT or MRI at baseline and CT scans and/or other radiographs performed every 56 days to assess the status of your tumor.

The study includes an optional part which will investigate how variations in people's genetic makeup affect their response to medications. This involves the collection of one blood sample just before participants receive their first dose of study treatment. DNA will be extracted from the blood sample for testing.

Study Groups

Carboplatin and Pemetrexed plus demcizumab

Carboplatin and Pemetrexed plus demcizumab

Group Type: EXPERIMENTAL

Demcizumab

Intervention Type: DRUG

The 6 subjects in the first cohort will receive demcizumab 5 mg/kg once every 3 weeks; the 6 subjects in the subsequent cohort will be treated with 10 mg/kg once every 3 weeks; and the 6 subjects in the final cohort will be treated with 15 mg/kg once every 3 weeks. A Data Safety Monitoring Board (DSMB) will review the data for the 6 subjects in each dose cohort after the last subject in that cohort has been on study for 56 days and then decide whether it is safe to escalate to the next highest dose cohort. Once the dose-escalation portion of the study has been completed, 14 additional subjects will be treated at the highest dose level that the DSMB deems as safe.

Inclusion Criteria

1. Subjects must have histologically confirmed unresectable, locally advanced, recurrent, or metastatic non-squamous NSCLC. Subjects may not have received prior therapy for their unresectable, locally advanced, recurrent, or metastatic non-squamous NSCLC. Subjects may have received prior surgery, prior radiotherapy, and/or prior neoadjuvant or adjuvant chemotherapy (they must have discontinued prior neoadjuvant or adjuvant chemotherapy at least 12 weeks prior to study entry).

2. Age >21 years

3. ECOG performance status <2 (see Appendix B)

4. Life expectancy of more than 3 months

5. Subjects must have normal organ and marrow function as defined below:

• Leukocytes >3.5 x 109/L
• Absolute neutrophil count >1.25 x 109/L Hemoglobin >100 g/L
• Platelets >125 X 109/L
