OBJECTIVES: IMbrella A is a Phase III extension study that allowed rollover from Roche/Genentech-sponsored atezolizumab trials, including IMpower133, a Phase I/III trial of first-line atezolizumab or placebo plus carboplatin/etoposide in extensive-stage small cell lung cancer. We report outcomes from an exploratory analysis of IMpower133 with extended time-to-event data for patients who rolled over to IMbrella A. MATERIALS AND METHODS: IMpower133 patients could roll over to IMbrella A to receive atezolizumab 1200 mg intravenously every three weeks if they continued to receive atezolizumab at IMpower133 closure or were in survival follow-up after atezolizumab discontinuation. Overall survival and safety were assessed; only serious adverse events and AEs of special interest were collected in IMbrella A. RESULTS: Eighteen of 26 eligible patients rolled over to IMbrella A. At clinical cutoff (March 16, 2023), median follow-up in the atezolizumab plus carboplatin/etoposide arm (IMpower133 and IMbrella A) was 59.4 months. The three-, four-, and five-year overall survival (95 % CI) estimates were 16 % (11 %-21 %), 13 % (8 %-18 %), and 12 % (7 %-17 %), respectively. In IMbrella A, serious adverse events occurred in three patients (16.7 %), and one adverse event of special interest was reported (grade two hypothyroidism). CONCLUSION: This long-term analysis of patients from IMbrella A previously enrolled in IMpower133 provides the first report of five-year overall survival outcomes in patients with extensive-stage small cell lung cancer treated with first-line cancer immunotherapy and chemotherapy. While limited by small patient numbers and lack of long-term data for the IMpower133 control arm, exploratory overall survival analyses in patients treated with atezolizumab plus carboplatin/etoposide compared favorably with historical data with chemotherapy alone.

BACKGROUND: Enhancing tumor-specific T-cell immunity by inhibiting programmed death ligand 1 (PD-L1)-programmed death 1 (PD-1) signaling has shown promise in the treatment of extensive-stage small-cell lung cancer. Combining checkpoint inhibition with cytotoxic chemotherapy may have a synergistic effect and improve efficacy. METHODS: We conducted this double-blind, placebo-controlled, phase 3 trial to evaluate atezolizumab plus carboplatin and etoposide in patients with extensive-stage small-cell lung cancer who had not previously received treatment. Patients were randomly assigned in a 1:1 ratio to receive carboplatin and etoposide with either atezolizumab or placebo for four 21-day cycles (induction phase), followed by a maintenance phase during which they received either atezolizumab or placebo (according to the previous random assignment) until they had unacceptable toxic effects, disease progression according to Response Evaluation Criteria in Solid Tumors, version 1.1, or no additional clinical benefit. The two primary end points were investigator-assessed progression-free survival and overall survival in the intention-to-treat population. RESULTS: A total of 201 patients were randomly assigned to the atezolizumab group, and 202 patients to the placebo group. At a median follow-up of 13.9 months, the median overall survival was 12.3 months in the atezolizumab group and 10.3 months in the placebo group (hazard ratio for death, 0.70; 95% confidence interval [CI], 0.54 to 0.91; P=0.007). The median progression-free survival was 5.2 months and 4.3 months, respectively (hazard ratio for disease progression or death, 0.77; 95% CI, 0.62 to 0.96; P=0.02). The safety profile of atezolizumab plus carboplatin and etoposide was consistent with the previously reported safety profile of the individual agents, with no new findings observed. CONCLUSIONS: The addition of atezolizumab to chemotherapy in the first-line treatment of extensive-stage small-cell lung cancer resulted in significantly longer overall survival and progression-free survival than chemotherapy alone.

BACKGROUND: Nivolumab has been associated with longer overall survival than docetaxel among patients with previously treated non-small-cell lung cancer (NSCLC). In an open-label phase 3 trial, we compared first-line nivolumab with chemotherapy in patients with programmed death ligand 1 (PD-L1)-positive NSCLC. METHODS: We randomly assigned, in a 1:1 ratio, patients with untreated stage IV or recurrent NSCLC and a PD-L1 tumor-expression level of 1% or more to receive nivolumab (administered intravenously at a dose of 3 mg per kilogram of body weight once every 2 weeks) or platinum-based chemotherapy (administered once every 3 weeks for up to six cycles). Patients receiving chemotherapy could cross over to receive nivolumab at the time of disease progression. The primary end point was progression-free survival, as assessed by means of blinded independent central review, among patients with a PD-L1 expression level of 5% or more. RESULTS: Among the 423 patients with a PD-L1 expression level of 5% or more, the median progression-free survival was 4.2 months with nivolumab versus 5.9 months with chemotherapy (hazard ratio for disease progression or death, 1.15; 95% confidence interval [CI], 0.91 to 1.45; P=0.25), and the median overall survival was 14.4 months versus 13.2 months (hazard ratio for death, 1.02; 95% CI, 0.80 to 1.30). A total of 128 of 212 patients (60%) in the chemotherapy group received nivolumab as subsequent therapy. Treatment-related adverse events of any grade occurred in 71% of the patients who received nivolumab and in 92% of those who received chemotherapy. Treatment-related adverse events of grade 3 or 4 occurred in 18% of the patients who received nivolumab and in 51% of those who received chemotherapy. CONCLUSIONS: Nivolumab was not associated with significantly longer progression-free survival than chemotherapy among patients with previously untreated stage IV or recurrent NSCLC with a PD-L1 expression level of 5% or more. Overall survival was similar between groups. Nivolumab had a favorable safety profile, as compared with chemotherapy, with no new or unexpected safety signals.

Purpose Patients with extensive-stage disease small-cell lung cancer (SCLC) have poor survival outcomes despite first-line chemotherapy with etoposide and platinum. This randomized, double-blind phase III study evaluated the efficacy and safety of ipilimumab or placebo plus etoposide and platinum in patients with newly diagnosed extensive-stage disease SCLC. Patients and Methods Patients were randomly assigned at a ratio of one to one to receive chemotherapy with etoposide and platinum (cisplatin or carboplatin) plus ipilimumab 10 mg/kg or placebo every 3 weeks for a total of four doses each in a phased induction schedule (chemotherapy in cycles one to four; ipilimumab or placebo beginning in cycle three up to cycle six), followed by ipilimumab or placebo maintenance every 12 weeks. Primary end point was overall survival (OS) among patients receiving at least one dose of blinded study therapy. Results Of 1,132 patients randomly assigned, 954 received at least one dose of study therapy (chemotherapy plus ipilimumab, n = 478; chemotherapy plus placebo, n = 476). Median OS was 11.0 months for chemotherapy plus ipilimumab versus 10.9 months for chemotherapy plus placebo (hazard ratio, 0.94; 95% CI, 0.81 to 1.09; P = .3775). Median progression-free survival was 4.6 months for chemotherapy plus ipilimumab versus 4.4 months for chemotherapy plus placebo (hazard ratio, 0.85; 95% CI, 0.75 to 0.97). Rates and severity of treatment-related adverse events were similar between arms, except for diarrhea, rash, and colitis, which were more frequent with chemotherapy plus ipilimumab. Rate of treatment-related discontinuation was higher with chemotherapy plus ipilimumab (18% v 2% with chemotherapy plus placebo). Five treatment-related deaths occurred with chemotherapy plus ipilimumab and two with chemotherapy plus placebo. Conclusion Addition of ipilimumab to chemotherapy did not prolong OS versus chemotherapy alone in patients with newly diagnosed extensive-stage disease SCLC. No new or unexpected adverse events were observed with chemotherapy plus ipilimumab. Several ongoing studies are evaluating ipilimumab in combination with programmed death-1 inhibitors in SCLC.

BACKGROUND: Patients with advanced squamous-cell non-small-cell lung cancer (NSCLC) who have disease progression during or after first-line chemotherapy have limited treatment options. This randomized, open-label, international, phase 3 study evaluated the efficacy and safety of nivolumab, a fully human IgG4 programmed death 1 (PD-1) immune-checkpoint-inhibitor antibody, as compared with docetaxel in this patient population. METHODS: We randomly assigned 272 patients to receive nivolumab, at a dose of 3 mg per kilogram of body weight every 2 weeks, or docetaxel, at a dose of 75 mg per square meter of body-surface area every 3 weeks. The primary end point was overall survival. RESULTS: The median overall survival was 9.2 months (95% confidence interval [CI], 7.3 to 13.3) with nivolumab versus 6.0 months (95% CI, 5.1 to 7.3) with docetaxel. The risk of death was 41% lower with nivolumab than with docetaxel (hazard ratio, 0.59; 95% CI, 0.44 to 0.79; P<0.001). At 1 year, the overall survival rate was 42% (95% CI, 34 to 50) with nivolumab versus 24% (95% CI, 17 to 31) with docetaxel. The response rate was 20% with nivolumab versus 9% with docetaxel (P=0.008). The median progression-free survival was 3.5 months with nivolumab versus 2.8 months with docetaxel (hazard ratio for death or disease progression, 0.62; 95% CI, 0.47 to 0.81; P<0.001). The expression of the PD-1 ligand (PD-L1) was neither prognostic nor predictive of benefit. Treatment-related adverse events of grade 3 or 4 were reported in 7% of the patients in the nivolumab group as compared with 55% of those in the docetaxel group. CONCLUSIONS: Among patients with advanced, previously treated squamous-cell NSCLC, overall survival, response rate, and progression-free survival were significantly better with nivolumab than with docetaxel, regardless of PD-L1 expression level.

Cieľ V štúdii fázy III INTEREST bolo 1 466 predliečených pacientov s pokročilým nemalobunkovým karcinómom pľúc (non–small-cell lung cancer, NSCLC) randomizovaných na liečbu gefi tinibom alebo docetaxelom. Ako predplánovanú analýzu sme prospektívne analyzovali dostupné tumorové biopsie za účelom skúmania vzťahu medzi biomarkermi a klinickými výsledkami. Metódy Biomarkery zahrňovali počet kópií receptoru epidermálneho rastového faktoru (epidermal growth factor receptor, EGFR) pomocou fl uorescenčnej in situ hybridizácie (374 dostupných vzoriek), expresiu EGFR proteínu pomocou imunohistochémie (n = 380), mutácie EGFR (n = 297) a KRAS (n = 275). Výsledky Pre všetky analyzované biomarkerové podskupiny bolo prežitie podobné pre gefi tinib aj docetaxel, so žiadnymi štatisticky signifi kantnými rozdielmi medzi liečbami a so žiadnymi signifi kantnými interakčnými testami medzi liečbou a biomarkerovým stavom. Pacienti s pozitívnou mutáciou EGFR mali dlhšie prežitie bez progresie (progression-free survival, PFS) (pomer rizík [hazard ratio,HR] 0,16; 95% interval spoľahlivosti [confi dence interval, CI] 0,05–0,49; p = 0,001) a vyššiu mieru objektívnych odpovedí (objective response rate, ORR) (42,1% vs. 21,1%; p = 0,04), a pacienti s vysokým počtom kópií EGFR mali vyšší ORR (13,0% vs. 7,4%; p = 0,04) s gefi tinibom vs. docetaxelom. Záver Tieto biomarkery sa nezdajú byť prediktívne faktory pre diferencované prežívanie medzi gefi tinibom a docetaxelom pri tejto indikácii u predtým liečených pacientov; avšak výsledky prežívania mohli byť ovplyvnené nasledujúcimi terapiami. Pre sekundárne ciele PFS a ORR boli pozorované niektoré výhody pre gefi tinib nad docetaxelom u pacientov s pozitívnou mutáciou EGFR a u pa cientov s vysokým počtom kópií EGFR. Nebol prítomný štatisticky signifi kantný rozdiel medzi gefi tinibom a docetaxelom u biomarker-negatívnych pacientov. To naznačuje, že gefi tinib je schopný poskytovať podobné celkové prežitie ako docetaxel u pacientov v rámci širokého spektra klinických podskupín a že EGFR biomarkery ako napr. mutačný stav môžu dodatočne identifi - kovať pacientov, ktorí budú môcť pravdepodobne získať najväčší úžitok v PFS a ORR z gefi tinibu.

Bevacizumab, a monoclonal antibody targeting vascular endothelial growth factor, improves survival when combined with carboplatin/paclitaxel for advanced nonsquamous non-small-cell lung cancer (NSCLC). This randomized phase III trial investigated the efficacy and safety of cisplatin/gemcitabine (CG) plus bevacizumab in this setting. PATIENTS AND METHODS: Patients were randomly assigned to receive cisplatin 80 mg/m2 and gemcitabine 1,250 mg/m(2) for up to six cycles plus low-dose bevacizumab (7.5 mg/kg), high-dose bevacizumab (15 mg/kg), or placebo every 3 weeks until disease progression. The trial was not powered to compare the two doses directly. The primary end point was amended from overall survival (OS) to progression-free survival (PFS). Between February 2005 and August 2006, 1,043 patients were randomly assigned (placebo, n = 347; low dose, n = 345; high dose, n = 351). RESULTS: PFS was significantly prolonged; the hazard ratios for PFS were 0.75 (median PFS, 6.7 v 6.1 months for placebo; P = .003) in the low-dose group and 0.82 (median PFS, 6.5 v 6.1 months for placebo; P = .03) in the high-dose group compared with placebo. Objective response rates were 20.1%, 34.1%, and 30.4% for placebo, low-dose bevacizumab, and high-dose bevacizumab plus CG, respectively. Duration of follow-up was not sufficient for OS analysis. Incidence of grade 3 or greater adverse events was similar across arms. Grade > or = 3 pulmonary hemorrhage rates were < or = 1.5% for all arms despite 9% of patients receiving therapeutic anticoagulation. CONCLUSION: Combining bevacizumab (7.5 or 15 mg/kg) with CG significantly improved PFS and objective response rate. Bevacizumab plus platinum-based chemotherapy offers clinical benefit for bevacizumab-eligible patients with advanced NSCLC.
