PURPOSE: Although checkpoint inhibitors have improved first-line treatment for non–small cell lung cancer (NSCLC), a therapeutic need remains for patients whose disease does not respond or who experience disease progression after anti–PD-L1/PD-1 immunotherapy. CONTACT-01 (ClinicalTrials.gov identifier: NCT04471428 ) evaluated atezolizumab plus cabozantinib versus docetaxel in patients with metastatic NSCLC who developed disease progression after concurrent or sequential treatment with anti–PD-L1/PD-1 and platinum-containing chemotherapy. METHODS: This multicenter, open-label, phase III trial randomly assigned patients 1:1 to atezolizumab 1,200 mg intravenously once every 3 weeks (q3w) plus cabozantinib 40 mg orally once daily or docetaxel 75 mg/m² intravenously once every 3 weeks. The primary end point was overall survival (OS). RESULTS: One hundred eighty-six patients were assigned atezolizumab plus cabozantinib, and 180 docetaxel. Minimum OS follow-up was 10.9 months. Median OS was 10.7 months (95% CI, 8.8 to 12.3) with atezolizumab plus cabozantinib and 10.5 months (95% CI, 8.6 to 13.0) with docetaxel (stratified hazard ratio [HR], 0.88 [95% CI, 0.68 to 1.16]; P = .3668). Median progression-free survival was 4.6 months (95% CI, 4.1 to 5.6) and 4.0 months (95% CI, 3.1 to 4.4), respectively (stratified HR, 0.74 [95% CI, 0.59 to 0.92]). Serious adverse events (AEs) occurred in 71 (38.4%) patients receiving atezolizumab plus cabozantinib and 58 (34.7%) receiving docetaxel. Grade 3/4 treatment-related AEs occurred in 73 (39.5%) patients receiving atezolizumab plus cabozantinib and 58 (34.7%) receiving docetaxel. Grade 5 AEs occurred in 14 (7.6%) and 10 (6.0%) patients in the atezolizumab plus cabozantinib and docetaxel arms, respectively (treatment-related in four [2.2%] and one [0.6%], respectively). CONCLUSION: Atezolizumab plus cabozantinib after disease progression following anti–PD-L1/PD-1 immunotherapy and platinum-containing chemotherapy for metastatic NSCLC did not improve OS compared with docetaxel. Safety was consistent with known profiles of these agents.

Based on the findings of the PACIFIC trial, consolidation durvalumab following platinum-based chemoradiotherapy (CRT) is a global standard of care for patients with unresectable, stage III non-small-cell lung cancer (NSCLC). An earlier analysis from the ongoing PACIFIC-R study (NCT03798535) demonstrated the effectiveness of this regimen in terms of progression-free survival (PFS). Here, we report the first planned overall survival (OS) analysis. PACIFIC-R is an observational/non-interventional, retrospective study of patients with unresectable, stage III NSCLC who started durvalumab (10 mg/kg intravenously every 2 weeks) within an AstraZeneca-initiated early access program between September 2017 and December 2018. Primary endpoints are OS and investigator-assessed PFS, estimated using the Kaplan-Meier method. By 30 November 2021, the full analysis set included 1154 participants from 10 countries (median follow-up in censored patients: 38.7 months). Median OS was not reached, and the 3-year OS rate was 63.2% (95% confidence interval 60.3% to 65.9%). Three-year OS rates were numerically higher among patients with programmed death-ligand 1 (PD-L1) expression on ≥1% versus <1% of tumor cells (TCs; 67.0% versus 54.4%) and patients who received concurrent CRT (cCRT) versus sequential CRT (sCRT) (64.8% versus 57.9%). PACIFIC-R data continue to provide evidence for the effectiveness of consolidation durvalumab after CRT in a large, diverse, real-world population. Better outcomes were observed among patients with PD-L1 TCs ≥1% and patients who received cCRT. Nevertheless, encouraging outcomes were still observed among patients with TCs <1% and patients who received sCRT, supporting use of consolidation durvalumab in a broad population of patients with unresectable, stage III NSCLC.

Malignant pleural mesothelioma (MPM) is a tumour arising from pleural cavities with poor prognosis. Multimodality treatment with pemetrexed combined with cisplatin shows unsatisfying response-rates of 40%. The reasons for the rather poor efficacy of chemotherapeutic treatment are largely unknown. However, it is conceivable that DNA repair mechanisms lead to an impaired therapy response. We hypothesize a major role of homologous recombination (HR) for genome stability and survival of this tumour. Therefore, we analysed genes compiled under the term “BRCAness”. An inhibition of this pathway with olaparib might abrogate this effect and induce apoptosis. We investigated the response of three MPM cell lines and lung fibroblasts serving as a control to treatment with pemetrexed, cisplatin and olaparib. Furthermore, we aimed to find possible correlations between response and gene expression patterns associated with BRCAness phenotype. Therefore, 91 clinical MPM samples were digitally screened for gene expression patterns of HR members. A BRCAness-dependent increase of apoptosis and senescence during olaparib-based treatment of BRCA-associated-protein 1 (BAP1)-mutated cell lines was observed. The gene expression pattern identified could be found in approx. 10% of patient samples. Against this background, patients could be grouped according to their defects in the HR system. Gene expression levels of Aurora Kinase A (AURKA), RAD50 as well as DNA damage-binding protein 2 (DDB2) could be identified as prognostic markers in MPM. Defects in HR compiled under the term BRCAness are a common event in MPM. The present data can lead to a better understanding of the underlaying cellular mechanisms and leave the door wide open for new therapeutic approaches for this severe disease with infaust prognosis. Response to Poly (ADP-ribose)-Polymerase (PARP)-Inhibition could be demonstrated in the BAP1-mutated NCI-H2452 cells, especially when combined with cisplatin. Thus, this combination therapy might be effective for up to 2/3 of patients, promising to enhance patients’ clinical management and outcome.

Patients receiving moderately emetogenic chemotherapy (MEC) are commonly prescribed a 5-hydroxytryptamine-3 (5-HT₃) receptor antagonist (RA) and dexamethasone (DEX) as standard-of-care (SOC) antiemetic prophylaxis. However, in patients with an elevated risk of chemotherapy-induced nausea and vomiting (CINV) due to individual risk factors, prophylaxis with an neurokinin-1 (NK₁) RA-containing regimen may optimise their antiemetic prevention. To address this unmet need for a more personalised antiemetic strategy, the MyRisk trial incorporated a predictive risk factor algorithm to select patients at increased risk of CINV who may benefit from enhanced antiemetic prophylaxis. MyRisk was a phase IV, randomised, open-label, multicentre, multinational trial. Adult patients scheduled to receive three cycles of MEC with a high-risk CINV score were randomly assigned to NEPA (a fixed combination of an NK₁ RA, netupitant, and 5-HT₃ RA, palonosetron) + DEX or SOC. The CINV risk score was calculated based on an algorithm that considered seven risk factors. The primary endpoint was complete response (CR: no emesis/no rescue medication) during the overall phase (0-120 h) across three consecutive cycles. Of 401 randomly allocated patients, 388 were included in the efficacy analysis. The most common cancers were colorectal and lung; oxaliplatin and carboplatin were the most common MECs. Patients randomly assigned to NEPA were significantly more likely to experience a CR compared with SOC (odds ratio 1.67, 95% confidence interval 1.12-2.49, P = 0.012). The NEPA group had a significantly higher probability of CR, no nausea, no emesis, and complete protection (81.0%, 63.7%, 95.4%, and 71.8%, respectively) compared with the SOC arm (71.8%, 54.9%, 86.7%, and 62.4%, respectively) across three cycles of chemotherapy. When individual risk factors are considered before MEC, a three-drug regimen including NEPA provides superior CINV prevention across multiple cycles compared with the standard two-drug approach. These findings underscore the value of personalised risk-adapted antiemetic strategies and have practice-changing potential for optimising antiemetic control.

Consolidation durvalumab is standard of care treatment for patients with unresectable, stage III non-small-cell lung cancer without progression after chemoradiotherapy. Additional study is warranted to investigate the long-term efficacy of this regimen in real-world settings. PACIFIC-R (NCT03798535) was an international, observational, cohort study of patients who started durvalumab 10 mg/kg intravenously every 2 weeks within an AstraZeneca-initiated early access program between September 2017 and December 2018. Data were extracted retrospectively from medical records to describe the real-world effectiveness of consolidation durvalumab in patients with unresectable non-small-cell lung cancer without progression after chemoradiotherapy. The primary endpoints were real-world progression-free survival (rwPFS) and overall survival (OS). Median age was 65.0 years (range 26-88 years); most patients [747/1153 (64.8%)] were male and current [300/1153 (26.0%)] or former [750/1153 (65.0%)] smokers. Among patients with reported data, most had Eastern Cooperative Oncology Group performance status <2 [743/755 (98.4%)], stage IIIB/C disease [584/1090 (53.6%)], non-squamous histology [746/1137 (65.6%)], and programmed death-ligand 1 expression on ≥1% of tumor cells [572/791 (72.3%)]. Median follow-up (censored patients) was 63.5 months for rwPFS and 67.5 months for OS. Median rwPFS was 24.3 months [95% confidence interval (CI) 20.3-28.4 months]; 5-year rwPFS was 35.2% (95% CI 32.4% to 38.1%). Median OS was 59.0 months (95% CI 52.7-64.3 months); 5-year OS was 49.2% (95% CI 46.2% to 52.2%). Encouraging results were observed across subgroups, including among patients who received durvalumab after either concurrent or sequential chemoradiotherapy [median rwPFS (95% CI): 25.8 months (20.9-31.8 months) versus 23.2 months (16.9-29.5 months); median OS: 63.1 months (57.3-73.5 months) versus 47.1 months (35.3-58.1 months)], and irrespective of programmed death-ligand 1 expression [on ≥1% versus <1% of tumor cells; median rwPFS (95% CI): 25.5 months (19.1-32.8 months) versus 16.3 months (10.9-27.5 months); median OS: 62.4 months (55.0 months-not estimable) versus 43.3 months (31.6-60.7) months]. PACIFIC-R provides mature data on OS and rwPFS from a large, real-world cohort, supporting consolidation durvalumab as a standard of care in this setting.
