Study Details

Study Description

Brief Summary

This clinical trial plans to assess to what extent the on-treatment circulating tumor DNA (ctDNA) can predict the subset of patients with NSCLC who will respond to immunotherapy treatment only and which patients will need both immunotherapy and chemotherapy modalities for their treatment regimen.

Condition or Disease	Intervention/Treatment	Phase
Carcinoma, Non-Small-Cell Lung	Drug: Nivolumab Drug: Ipilimumab Drug: Carboplatin Drug: Paclitaxel Drug: Pemetrexed	Phase 2

Detailed Description

Subjects will be randomized 2:1 and patients in both arms will begin treatment with nivolumab 360 mg intravenously every 3 weeks and ipilimumab 1 mg/kg intravenously every 6 weeks. At five weeks of treatment, subjects will have ctDNA response evaluation with Guardant360 Response assay. At the next cycle of treatment (+/- 2 days), patients in the larger arm will receive treatment based on the Guardant360 Response assay results, as described below. Subjects will undergo ctDNA evaluation with Guardant360 Response assay 6- week post-randomization and at the time of progression. Response to therapy will be assessed by interval imaging with CT scan of the chest/abdomen/pelvis (and MRI brain if applicable) with response evaluated by irRECIST criteria every 12 weeks until disease progression.

Outcome Measures

Primary Outcome Measures

Progression Free Survival (PFS) [Time from randomization to objective disease progression, or death from any cause, whichever first, up to 36 months]
To compare progression free survival in patients with on-treatment-ctDNA guided therapy continuation or escalation by addition of platinum-doublet chemotherapy to therapy continuation with Nivolumab-Ipilimumab regardless of on-treatment-ctDNA results.

Secondary Outcome Measures

Progression Free Survival on Subsequent line of therapy (PFS2) [Duration of time from randomization to second objective disease progression, or death from any cause, whichever first, up to 36 months]
To compare progression free survival on subsequent line of therapy (PFS2) between patients with on-treatment-ctDNA guided therapy continuation or escalation by addition of platinum-doublet chemotherapy to therapy continuation with Nivolumab-Ipilimumab regardless of on-treatment-ctDNA results
Overall Survival [Duration of time from first treatment to time of death, up to 36 months]
To compare overall survival (OS) in patients with on-treatment-ctDNA guided therapy continuation or escalation by addition of platinum-doublet chemotherapy to therapy continuation with Nivolumab-Ipilimumab regardless of on-treatment-ctDNA results
Objective Response Rate [Duration of time between the date of first treatment and the date of objectively documented progression per irRECIST or the date of initiation of palliative local therapy or the date of subsequent anti-cancer therapy, whichever occurs first, up to 36 mo]
To compare objective response rate (ORR) in patients with on-treatment-ctDNA guided therapy continuation or escalation by addition of platinum-doublet chemotherapy to therapy continuation with Nivolumab-Ipilimumab regardless of on treatment-ctDNA results.
Duration of Response [Duration of time between the date of first confirmed response to the date of the first documented tumor progression (per irRECIST), or death due to any cause, whichever occurs first, up to 36 months]
To compare duration of response (DOR) in patients with on-treatment-ctDNA guided therapy continuation or escalation by addition of platinum-doublet chemotherapy to therapy continuation with Nivolumab-Ipilimumab regardless of on-treatment-ctDNA results.
