Dr. Maen Hussein's Thoughts

Combination immunotherapy beats chemotherapy, there is no data to compare against a chemo immunotherapy combination, but is an option for patients who may not tolerate chemotherapy.

PURPOSE

We present 5-year results from CheckMate 227 Part 1, in which nivolumab plus ipilimumab improved overall survival (OS) versus chemotherapy in patients with metastatic non–small-cell lung cancer, regardless of tumor programmed death ligand 1 (PD-L1) status.

METHODS

Adults with stage IV/recurrent non–small-cell lung cancer without EGFR mutations or ALK alterations and with tumor PD-L1 ≥ 1% or < 1% (n = 1739) were randomly assigned. Patients with tumor PD-L1 ≥ 1% were randomly assigned to first-line nivolumab plus ipilimumab, nivolumab alone, or chemotherapy. Patients with tumor PD-L1 < 1% were randomly assigned to nivolumab plus ipilimumab, nivolumab plus chemotherapy, or chemotherapy. End points included exploratory 5-year results for efficacy, safety, and quality of life.

RESULTS

At a minimum follow-up of 61.3 months, 5-year OS rates were 24% versus 14% for nivolumab plus ipilimumab versus chemotherapy (PD-L1 ≥ 1%) and 19% versus 7% (PD-L1 < 1%). The median duration of response was 24.5 versus 6.7 months (PD-L1 ≥ 1%) and 19.4 versus 4.8 months (PD-L1 < 1%). Among patients surviving 5 years, 66% (PD-L1 ≥ 1%) and 64% (PD-L1 < 1%) were off nivolumab plus ipilimumab without initiating subsequent systemic anticancer treatment by the 5-year time point. Survival benefit continued after nivolumab plus ipilimumab discontinuation because of treatment-related adverse events, with a 5-year OS rate of 39% (combined PD-L1 ≥ 1% and < 1% populations). Quality of life in 5-year survivors treated with nivolumab plus ipilimumab was similar to that in the general US population through the 5-year follow-up. No new safety signals were observed.

CONCLUSION

With all patients off immunotherapy treatment for ≥ 3 years, nivolumab plus ipilimumab increased 5-year survivorship versus chemotherapy, including long-term, durable clinical benefit regardless of tumor PD-L1 expression. These data support nivolumab plus ipilimumab as an effective first-line treatment for patients with metastatic non–small-cell lung cancer.

Perioperative nivolumab (Nivo) showed a 20% 18-month EFPS improvement. This is another option to consider for your patients with stage IIA-IIIB NSCLC. Of note, the study arm received chemo + Nivo x 4 cycles preoperatively, then 12 months of Nivo therapy, and toxicities were as expected.

Plasma Proteome–Based Test for First-Line Treatment Selection in Metastatic Non–Small Cell Lung Cancer

FCS medical oncologist and hematologist Ernesto Bustinza-Linares, MD has co-authored an abstract published in the American Society of Clinical Oncology Journal, JCO Precision Oncology, that uncovers a new testing method to determine personalized care options for patients with metastatic non-small cell lung cancer (NSCLC). The abstract’s authors address the limitations of existing guidelines that recommend checkpoint immunotherapy, sometimes in combination with chemotherapy, for treating NSCLC, which often discounts patient variability and immune factors. The findings from the study show that by incorporating additional plasma proteome-based testing, combined with the standard protein inhibitor testing, clear differences in patient outcomes were observed after applying targeted treatments based on the testing results.

Phase III, Randomized Study of Atezolizumab Plus Bevacizumab and Chemotherapy in Patients With EGFR- or ALK-Mutated Non–Small-Cell Lung Cancer (ATTLAS, KCSG-LU19-04)

Adding VEGF inhibitor to PD-1 blocker in addition to chemotherapy is better than a chemotherapy-alone regimen as a second-line therapy after TKI failure. This is true especially in patients with tumors with high PD-L1 expression, with not much besides chemotherapy as second-line therapy for those patients (or other clinical trials) that may be a better option that includes immunotherapy.

A question for the previous trial would be: do we need PDL-1 inhibitor, or just VEGF inhibitor, recall the pts with tumors with high PDL-1 expression did better though, so most likely we need both with chemotherapy.
