Details and patient eligibility

About

This study is an open label, multicenter, randomized phase II trial of consolidation immunotherapy with either nivolumab alone or the combination of nivolumab and ipilimumab following concurrent chemoradiation in patients with unresectable stage III NSCLC.

Full description

Patients with unresectable stage IIIA or IIIB NSCLC (unresectable as defined by treating physician) will be treated outside this study with concurrent chemoradiation with one of three chemotherapy regimens (cisplatin/etoposide, cisplatin/pemetrexed, or weekly carboplatin/paclitaxel) in addition to standard dose radiation (dosing can range from 59.4 Gy to 66.6 Gy). If repeat imaging between 28-56 days following completion of chemoradiation shows no progressive or metastatic disease, the patients will be eligible for enrollment on the study.

Randomization and Stratification:

At the time of enrollment, patients will be randomized in a 1:1 fashion to receive either nivolumab 480mg IV every 4 weeks or the combination of nivolumab 3mg/kg IV every 2 weeks with ipilimumab 1mg/kg IV every 6 weeks. Consolidation immunotherapy will be continued until progression or unacceptable toxicity for up to a total of 24 weeks.

Subjects will be stratified by stage (IIIA vs. IIIB) and histology (squamous vs. non-squamous).

Dose Calculations:

Arm 1: The dose of nivolumab will be a fixed dose (not based on subject's weight) at 480mg.

Arm 2: The dose of nivolumab will be weight-based at 3mg/kg. The dose of ipilimumab will be weight-based at 1mg/kg.

Nivolumab Alone (Arm 1):

Arm 1: Nivolumab Administration:

Nivolumab 480 mg will be administered as a 60 minute IV infusion on Day 1 of each 28 day cycle. Sites should make every effort to target infusion timing to be as close to 60 minutes as possible. However, given the variability of infusion pumps from site to site, a window of -five minutes and +10 minutes is permitted (i.e., infusion time is 60 minutes: -5 min/+10 min). Treatment will continue for up to 6 cycles, in the absence of prohibitive toxicities or disease progression.

Nivolumab Plus Ipilimumab (Arm 2):

Arm 2: Nivolumb Administration:

Nivolumab 3mg/kg will be administered as a 60 minute IV infusion on Day 1, 15, and 29 of each 42 day cycle. Nivolumab should not be given any earlier than 12 days from the previous dose. Sites should make every effort to target infusion timing to be as close to 60 minutes as possible. However, given the variability of infusion pumps from site to site, a window of -five minutes and +10 minutes is permitted (i.e., infusion time is 60 minutes: -5 min/+10 min). Treatment will continue for up to 4 cycles, in the absence of prohibitive toxicities or disease progression.

Arm 2: Ipilimumab Administration:

Ipilimumab 1mg/kg will be administered as a 90 minute IV infusion on Day 1 of each 42 day cycle. Sites should make every effort to target infusion timing to be as close to 90 minutes as possible. However, given the variability of infusion pumps from site to site, a window of -five minutes and +10 minutes is permitted (i.e., infusion time is 60 minutes: -5 min/+10 min). Treatment will continue for up to 4 cycles, in the absence of prohibitive toxicities or disease progression.

On day 1 of cycle 1, nivolumab will be given first, followed by 30 minutes of monitoring, and then ipilimumab given second, followed by 30 minutes of monitoring. If the subject does not have an infusion reaction during the first cycle, the post-ipilimumab monitoring may be discontinued for subsequent cycles at the discretion of the treating physician. Day 1 monitoring between the nivolumab/ipilimumab infusions will continue throughout all 4 cycles. Post nivolumab monitoring on days 15 and 29 is not mandatory and should follow the guidelines of the local infusion center.

Inclusion criteria

Subject must meet all of the following applicable inclusion criteria to participate in this study:

• Written informed consent and HIPAA authorization for release of personal health information.
• Age ≥ 18 years at the time of consent.
• ECOG Performance Status of 0 or 1 within 14 days prior to registration.
• Histological or cytological confirmation of NSCLC. A pathology report confirming the diagnosis of NSCLC must be obtained and reviewed by the treating physician prior to registration to study.
• Must have unresectable or inoperable stage IIIA or IIIB disease according to the 7th edition IASLC stage classification for lung cancer. Subjects must be considered unresectable or inoperable based on the judgment of the treating physician.
• Subjects must have completed concurrent chemoradiation with a platinum doublet and a dose of radiation ranging from 59.4-66.6 Gy. Subjects must have stable disease or disease response as evidenced on CT or PET scan evaluation. For those eligible, protocol therapy should begin within 56 days of completing chemoradiation OR Subjects must have completed up to 2 cycles of consolidation therapy started within 56 days of completion of radiation. After completion of consolidation chemotherapy, subjects must have stable disease or disease response as evidenced by CT or PET scan evaluation. For those eligible, protocol therapy should begin within 56 days after the last cycle of chemotherapy.
• Prior cancer treatment must be completed between 1-56 days prior to registration and the subject must have recovered from all reversible acute toxic effects of the regimen (other than alopecia) to ≤Grade 1 or baseline.
• Demonstrate adequate organ function, all screening labs to be obtained within 14 days prior to registration:

Hematological:

• Absolute Neutrophil Count (ANC) ≥ 1.5 K/mm^3
• Hemoglobin (Hgb) ≥ 9 g/dL
• Platelets ≥100,000/mcl

Renal:

• Serum creatinine OR Measured or calculated creatinine clearance (GFR can also be used in place of creatinine or CrCl) ≤ 1.5 x upper limit of normal (ULN) OR ≥ 60 mL/min for subjects with creatinine levels >1.5 x institutional ULN

Hepatic:
