Objective: Patients with relapsed or metastatic head and neck squamous cell carcinoma (HNSCC) after primary local therapy have low response rates with cetuximab, systemic chemotherapy or check point inhibitor therapy. Novel combination therapies with the potential to improve outcomes for patients with HNSCC is an area of high unmet need.
Methods: This is a phase II single-arm clinical trial of locally advanced or metastatic HNSCC patients treated with a combination of soluble EphB4-human serum albumin (sEphB4-HSA) fusion protein and pembrolizumab after platinum-based chemotherapy with up to 2 prior lines of treatment.
Background: Tumor samples from the phase III IMpower010 study were used to compare two programmed death-ligand 1 (PD-L1) immunohistochemistry assays (VENTANA SP263 and Dako 22C3) for identification of PD-L1 patient subgroups (negative, positive, low, and high expression) and their predictive value for adjuvant atezolizumab compared with best supportive care (BSC) in resectable early-stage non-small cell lung cancer (NSCLC).
Methods: PD-L1 expression was assessed by the SP263 assay, which measured the percentage of tumor cells with any membranous PD-L1 staining, and the 22C3 assay, which scored the percentage of viable tumor cells showing partial or complete membranous PD-L1 staining.
Results: When examining the concordance at the PD-L1-positive threshold (SP263: tumor cell (TC)≥1%; 22C3: tumor proportion score (TPS)≥1%), the results were concordant between assays for 83% of the samples.
Background: IMpower010 (NCT02486718) demonstrated significantly improved disease-free survival (DFS) with adjuvant atezolizumab versus best supportive care (BSC) following platinum-based chemotherapy in the programmed death-ligand 1 (PD-L1)-positive and all stage II-IIIA non-small-cell lung cancer (NSCLC) populations, at the DFS interim analysis. Results of the first interim analysis of overall survival (OS) are reported here.
Patient And Methods: The design, participants, and primary-endpoint DFS outcomes have been reported for this phase III, open-label, 1 : 1 randomised study of atezolizumab (1200 mg q3w; 16 cycles) versus BSC after adjuvant platinum-based chemotherapy (1-4 cycles) in adults with completely resected stage IB (≥4 cm)-IIIA NSCLC (per the Union Internationale Contre le Cancer and American Joint Committee on Cancer staging system, 7th edition).
Objective: Adjuvant atezolizumab is a standard of care after chemotherapy in completely resected stage II-IIIA programmed death ligand-1 tumor cell 1% or greater non-small cell lung cancer based on results from the phase III IMpower010 study. We explored the safety and tolerability of adjuvant atezolizumab by surgery type in IMpower010.
Methods: Patients had completely resected stage IB-IIIA non-small cell lung cancer (Union Internationale Contre le Cancer/American Joint Committee on Cancer, 7th Ed), received up to four 21-day cycles of cisplatin-based chemotherapy, and were randomized 1:1 to receive atezolizumab 1200 mg every 3 weeks (≤16 cycles or 1 year) or best supportive care.
Background: This review describes a new therapeutic landscape in the adjuvant treatment of resectable non-small cell lung cancer (NSCLC) and discusses the role of the surgeon in ensuring the best outcomes within this treatment paradigm.
Methods: We conducted a narrative literature review using the search terms "non-small cell lung cancer" and "adjuvant" to identify randomized Phase III trials of systemic adjuvant therapy for NSCLC through March 17, 2022. We also searched ClinicalTrials.
