Purpose The AVAglio (Avastin in Glioblastoma) and RTOG-0825 randomized, placebo-controlled phase III trials in newly diagnosed glioblastoma reported prolonged progression-free survival (PFS), but not overall survival (OS), with the addition of bevacizumab to radiotherapy plus temozolomide. To establish whether certain patient subgroups derived an OS benefit from the addition of bevacizumab to first-line standard-of-care therapy, AVAglio patients were retrospectively evaluated for molecular subtype, and bevacizumab efficacy was assessed for each patient subgroup. Patients and Methods A total of 349 pretreatment specimens (bevacizumab arm, n = 171; placebo arm, n = 178) from AVAglio patients (total, N = 921) were available for biomarker analysis. Samples were profiled for gene expression and isocitrate dehydrogenase 1 (IDH1) mutation status and classified into previously identified molecular subtypes. PFS and OS were assessed within each subtype. Results A multivariable analysis accounting for prognostic covariates revealed that bevacizumab conferred a significant OS advantage versus placebo for patients with proneural IDH1 wild-type tumors (17.1 v 12.8 months, respectively; hazard ratio, 0.43; 95% CI, 0.26 to 0.73; P = .002). This analysis also revealed an interaction between the proneural subtype biomarker and treatment arm (P = .023). The group of patients with mesenchymal and proneural tumors derived a PFS benefit from bevacizumab compared with placebo; however, this translated to an OS benefit in the proneural subset only. Conclusion Retrospective analysis of AVAglio data suggests that patients with IDH1 wild-type proneural glioblastoma may derive an OS benefit from first-line bevacizumab treatment. The predictive value of the proneural subtype observed in AVAglio should be validated in an independent data set.

For a long time, chemotherapy remained the main treatment option for metastatic urothelial carcinoma (mUC). Over the past year, there have been revolutionary changes associated with the approval of five new drugs aimed at blocking the interaction between the surface protein of T‑lymphocytes PD‑1 and its ligands PD‑L1 and PD‑L2, resulting in the activation of the immune response. It is noteworthy that the anti‑PD‑1 antibody pembrolizumab demonstrated an increase in overall survival relative to chemotherapy in a randomized phase III trial in the second line with mUC. Based on this level 1 evidence pembrolizumab was approved by the US Food and Drug Administration (FDA). Nivolumab (antibody PD‑1) also demonstrated an increase in overall survival compared to historical control and was approved by FDA. Likewise, antibodies targeting PD‑L1, including atezolizumab, durvalumab and avelumab, received accelerated approval from the FDA as the second line of treatment for mUC. Some of these agents are approved in the first line by the results of phase II study (atezolizumab and pembolizumab received accelerated approval for first‑line treatment in patients not receiving cisplatin). Despite these many endorsements, clinical development of new biomarkers for selection of patients, who can get maximum advantages of immunotherapy and also for development the optimal therapy sequencing still are biggest and critical question for future investigation.The clinical introduction of biomarkers to determine optimal treatment of patients remains extremely important.

Purpose. We aimed to identify new predictive biomarkers for cetuximab in first-line treatment for patients with RAS wild-type metastatic colorectal cancer (mCRC). Methods. The study included patients with KRAS wild-type unresectable liver-limited mCRC treated with chemotherapy with or without cetuximab. Next-generation sequencing was done for single nucleotide polymorphism according to custom panel. Potential predictive biomarkers were identified and integrated into a predictive model within a training cohort. The model was validated in a validation cohort. Results. Thirty-one of 247(12.6%) patients harbored RAS mutations. In training cohort (N=93), six potential predictive genes, namely, ATP6V1B1, CUL9, ERBB2, LY6G6D, PTCH1, and RBMXL3, were identified. According to predictive model, patients were divided into responsive group (n=66) or refractory group (n=27). In responsive group, efficacy outcomes were significantly improved by addition of cetuximab to chemotherapy. In refractory group, no benefit was observed. Interaction test was significant across all endpoints. In validation cohort (N=123), similar results were also observed. Conclusions. In the first-line treatment of mCRC, the predictive model integrating six new predictive mutations divided patients well, indicating a promising approach to further refine patient selection for cetuximab on the basis of RAS mutations.

ObjectivesCetuximab plus leucovorin, fluorouracil and oxaliplatin (FOLFOX-4) is superior to FOLFOX-4 alone as a first-line treatment for patients with metastatic colorectal cancer with RAS wild-type (RAS wt mCRC), with significantly improved survival benefit by TAILOR, an open-label, randomised, multicentre, phase III trial. Nevertheless, the cost-effectiveness of these two regimens remains uncertain. The following study aims to determine whether cetuximab combined with FOLFOX-4 is a cost-effective regimen for patients with specific RAS wt mCRC in China.DesignA cost-effectiveness model combined decision tree and Markov model was built to simulate pateints with RAS wt mCRC based on health states of dead, progressive and stable. The health outcomes from the TAILOR trial and utilities from published data were used respectively. Costs were calculated with reference to the Chinese societal perspective. The robustness of the results was evaluated by univariate and probabilistic sensitivity analyses.ParticipantsThe included patients were newly diagnosed Chinese patients with fully RAS wt mCRC.InterventionsFirst-line treatment with either cetuximab plus FOLFOX-4 or FOLFOX-4.Main outcome measuresThe primary outcomes are costs, quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICERs).ResultsBaseline analysis disclosed that the QALYs was increased by 0.383 caused by additional cetuximab, while an increase of US$62 947 was observed in relation to FOLFOX-4 chemotherapy. The ICER was US$164 044 per QALY, which exceeded the willingness-to-pay threshold of US$28 106 per QALY.ConclusionsDespite the survival benefit, cetuximab combined with FOLFOX-4 is not a cost-effective treatment for the first-line regime of patients with RAS wt mCRC in China.Trial registration numberTAILOR trial (NCT01228734); Post-results.

Introduction/Objective: Lenvatinib demonstrated efficacy and safety in patients with advanced hepatocellular carcinoma (HCC) in the randomized phase III REFLECT trial. Considering the discrepancies in patients between clinical trial data and daily practice, an account of practical experience is needed. Methods: We conducted a multicenter retrospective analysis in which 3 tertiary referral centers participated. A total of 92 patients with advanced HCC treated with lenvatinib between September 2018 and January 2020 were analyzed. Results: Lenvatinib was used as the first-line therapy for 67 (72.8%) patients, and for 25 (27.2%) patients previously treated with other systemic therapy including immune checkpoint inhibitors. At the time of initiation of lenvatinib, 74 (80.4%) and 18 (19.6%) patients were classified as Child-Pugh A and B, respectively. Thirty-five patients (38.0%) had extensive disease that would have excluded them from the REFLECT trial. In the Child-Pugh A group, the response rate graded according to the Response Evaluation Criteria in Solid Tumors v1.1 was 21.1%, median progression-free survival (PFS) was 4.6 (95% confidence interval [CI] 3.1–6.1) months, and overall survival (OS) was 10.7 (95% CI 4.8–16.5) months for patients treated with first-line lenvatinib (n = 57). With second- or later-line lenvatinib (n = 17), median PFS and OS were 4.1 (95% CI 3.1–5.1) and 6.4 (95% CI 5.1–7.7) months, respectively. In the Child-Pugh B group (n = 18), median PFS and OS were 2.6 (95% CI 0.6–4.6) and 5.3 (95% CI 2.0–8.5) months, respectively. The most common grade 3–4 toxicities were hyperbilirubinemia (n = 8; 8.7%), AST elevation (n = 6; 6.5%), and diarrhea (n = 5; 5.4%) across all study patients. Conclusions: In this real-world study, lenvatinib was found to be well tolerated and effective in more heterogeneous HCC patient populations.

PURPOSE: This phase III trial compared the efficacy and safety of doxorubicin and paclitaxel (AT) to 5-fluorouracil, doxorubicin, and cyclophosphamide (FAC) as first-line therapy for women with metastatic breast cancer. PATIENTS AND METHODS: A total of 267 women with metastatic breast cancer were randomized to receive either AT (doxorubicin 50 mg/m2 followed 24 hours later by paclitaxel 220 mg/m2) or FAC (5-fluorouracil 500 mg/m2, doxorubicin 50 mg/m2, cyclophosphamide 500 mg/m2), each administered every 3 weeks for up to eight cycles. Patients had to have measurable disease and an Eastern Cooperative Oncology Group performance status of 0 to 2. Only one prior non–anthracycline, nontaxane-containing adjuvant chemotherapy regimen was allowed. RESULTS: Overall response rates for patients randomized to AT and FAC were 68% and 55%, respectively (P = .032). Median time to progression and overall survival were significantly longer for AT compared with FAC (time to progression 8.3 months v 6.2 months [P = .034]; overall survival 23.3 months v 18.3 months [P = .013]). Therapy was generally well-tolerated (median of eight cycles delivered in each arm). Grade 3 or 4 neutropenia was more common with AT than with FAC (89% v 65%; P < .001); however, the incidence of fever and infection was low. Grade 3 or 4 arthralgia and myalgia, peripheral neuropathy, and diarrhea were more common with AT, whereas nausea and vomiting were more common with FAC. The incidence of cardiotoxicity was low in both arms. CONCLUSION: AT conferred a significant advantage in response rate, time to progression, and overall survival compared with FAC. Treatment was well-tolerated with no unexpected toxicities.
