About

Phase II study to determine progression free survival (PFS) of nab-paclitaxel administered in combination with gemcitabine, at two different dose combinations as first line therapy in patients with unresectable stage IIIB/stage IV non-squamous non-small cell lung cancer (NSCLC).

Full description

This study is designed determine progression free survival (PFS) of nab-paclitaxel administered in combination with gemcitabine at two different dose combinations in patients with unresectable stage IIIB/stage IV non-squamous non-small cell lung cancer (NSCLC). Two dosing strategies of the nab-paclitaxel plus gemcitabine combination will be compared for efficacy and tolerability. One arm will combine both agents at their current Food and Drug Administration (FDA) approved doses for the indication of non-small cell lung cancer (NSCLC). This arm will utilize gemcitabine 1250 mg/m2 IV day 1 and day 8 (FDA approved dose in combination with cisplatin) combined with nab-paclitaxel 100 mg/m2 IV day 1, 8 and 15 every 21 days (FDA approved dose in combination with carboplatin). The second arm will utilize the drugs at doses that are approved by the FDA when combined with one another in metastatic pancreatic adenocarcinoma. This arm will consist of gemcitabine 1000 mg/m2 IV day 1, 8 and 15 combined with nab-paclitaxel at 125 mg/m2 IV day 1, 8 and 15 every 28 days. Patients will be randomized equally to the two treatment arms. Primary objective is to assess progression-free survival (PFS). Toxicity assessment, response and overall survival are secondary endpoints. Statistical power is based on the comparison to historical control within each treatment arm. In particular, a sample size of 23 patients in each arm will have 84% power to differentiate the 3-month PFS of 30% (null hypothesis) versus 60% (alternative) based on a 2-sided test at a significance level of 0.05. There will be a lead-in phase to this trial for each treatment arm with a cohort size of 3 and a maximum of 6 patients.

Inclusion criteria

• Patients with histologically proven newly diagnosed stage IV or stage IIIB non-squamous Non-small Cell Lung Cancer (NSCLC) - Recurrent advanced NSCLC will be allowed if they have never received chemotherapy for metastatic disease. - Prior adjuvant chemotherapy will be allowed, if recurrence occurred ≥ 6 months after last treatment
• Eastern Cooperative Oncology Group (ECOG) performance status 0-1
• Measurable disease as per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1
• Washout period of 4 weeks for chemo/radiation/experimental agents
• Resolution of all toxicities to < grade 2 prior to starting treatment (excluding alopecia)
• Patients must have < Grade 2 pre-existing peripheral neuropathy (per CTCAE)
• Adequate hepatic, renal, and bone marrow functions
• Women of childbearing potential and sexually active males must use an effective contraception method during treatment and for three months after completing treatment
• Negative serum or urine β-hCG pregnancy test at screening for patients of childbearing potential

Exclusion criteria

• Patient with New York Heart Association class III or IV heart failure
• Women of child bearing potential (WOCBP) are not currently pregnant or breast-feeding
• Co-existing malignancy or malignancies diagnosed within the last 3 years with the exception of basal cell carcinoma
• Previous anaphylactic or severe allergic reaction to paclitaxel and/or docetaxel will be excluded
• Grade ≥2 peripheral neuropathy at baseline assessment from any cause
• Symptomatic brain metastases will be excluded. Treated Brain metastases will be allowed that are neurologically stable.
• Patients with adenocarcinoma with activating EGFR mutation (exon 19 deletions / insertions, exon 21 point mutations) or EML4-ALK translocation are excluded unless they are ineligible for epidermal growth factor receptor (EGFR) or ALK targeting agents.
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

0 participants in 2 patient groups

A - Nab-paclitaxel 100mg + Gemcitabine 1250mg

Experimental group

Description:

Nab-paclitaxel 100 mg/m2 as a 30 minute infusion (maximum infusion time not to exceed 40 minutes) on days 1, 8 and 15 of a 21 day cycle. On days 1 and 8 of each cycle, nab-paclitaxel administration will be followed by the administration of gemcitabine 1250 mg/m2 as a 30 minute infusion (maximum 40 minutes).

Treatment:

Drug: Nab-paclitaxel

Drug: Gemcitabine

B - Nab-paclitaxel 125mg + Gemcitabine 1000mg

Experimental group

Description:

Nab-paclitaxel 125 mg/m2 as a 30 minute infusion (maximum infusion time not to exceed 40 minutes) on days 1, 8 and 15 of a 28 day cycle. Each nab-paclitaxel administration will be followed by the administration of gemcitabine 1000 mg/m2 as a 30 minute infusion (maximum 40 minutes) on days 1, 8 and 15. Treatments will be repeated until progression or intolerance.
