Randomized Phase II Study of Docetaxel plus Personalized Peptide Vaccination versus Docetaxel plus Placebo for Patients with Previously Treated Advanced Wild Type EGFR Non-Small-Cell Lung Cancer.

ABSTRACT: Objectives. To evaluate the efficacy and safety of personalized peptide vaccination (PPV) combined with chemotherapy for patients with previously treated advanced non-small-cell lung cancer (NSCLC). Patients and Methods. Previously treated PS0-1 patients with IIIB/IV EGFR (epidermal growth factor receptor) wild genotype NSCLC were randomly assigned to docetaxel (60?mg/m(2) on Day 1) plus PPV based on preexisting host immunity or docetaxel plus placebo. Docetaxel administration was repeated every 3 weeks until disease progression. Personalized peptides or placebo was injected subcutaneously weekly in the first 8 weeks and biweekly in subsequent 16 weeks. The primary efficacy endpoint was progression-free survival (PFS). Results. PPV related toxicity was grade 2 or less skin reaction. The median PFS for placebo arm and PPV arm was 52 days and 59 days, respectively. There was no significant difference between two arms by log-rank test (p = 0.42). Interestingly, PFS and overall survival (OS) in humoral immunological responder were significantly longer than those in nonresponder. Conclusion. PPV did not improve the survival in combination with docetaxel for previously treated advanced NSCLC. However, PPV may be efficacious for the humoral immunological responders and a further clinical investigation is needed.

Project description:BackgroundBavituximab is a monoclonal antibody that targets phosphatidylserine in the presence of β2 glycoprotein 1 (β2GP1) to exert an antitumor immune response. This phase III trial determined the efficacy of bavituximab combined with docetaxel in patients with previously treated advanced non-small-cell lung cancer (NSCLC).Patients and methodsKey eligibility criteria included advanced non-squamous NSCLC with disease progression after treatment with platinum-based doublet chemotherapy, evidence of disease control after at least two cycles of first-line therapy, presence of measurable disease, ECOG performance status 0 or 1, adequate bone marrow and organ function, and no recent history of clinically significant bleeding. Eligible patients were randomized 1 : 1 to receive up to six 21-day cycles of docetaxel plus either weekly bavituximab 3 mg/kg or placebo until progression or toxicity. The primary end point was overall survival (OS).ResultsA total of 597 patients were enrolled. Median OS was 10.5 months in the docetaxel + bavituximab arm and was 10.9 months in the docetaxel + placebo arm (HR 1.06; 95% CI 0.88-1.29; P = 0.533). There was no difference in progression-free survival (HR 1.00; 95% CI 0.82-1.22; P = 0.990). Toxicities were manageable and similar between arms. In subset analysis, among patients with high baseline serum β2GP1 levels ≥200 µg/ml, a nonsignificant OS trend favored the bavituximab arm (HR 0.82; 95% CI 0.63-1.06; P = 0.134). Among patients who received post-study immune checkpoint inhibitor therapy, OS favored the bavituximab arm (HR 0.46; 95% CI 0.26-0.81; P = 0.006).ConclusionsThe combination of bavituximab plus docetaxel is not superior to docetaxel in patients with previously treated advanced NSCLC. The addition of bavituximab to docetaxel does not meaningfully increase toxicity. The potential benefit of bavituximab observed in patients with high β2GP1 levels and in patients subsequently treated with immune checkpoint inhibitors requires further investigation.Clinical trial numberNCT01999673.

Project description:ImportanceBecause of socioeconomic factors, many patients with advanced non-small cell lung cancer (NSCLC) do not receive immunotherapy in the first-line setting. It is unknown if the combination of immunotherapy with chemotherapy can provide clinical benefits in immunotherapy-naive patients with disease progression after treatment with platinum-based chemotherapy.ObjectiveTo evaluate the safety and efficacy of the combination of pembrolizumab plus docetaxel in patients with previously treated advanced NSCLC following platinum-based chemotherapy regardless of EGFR variants or programmed cell death ligand 1 status.Design, setting, and participantsThe Pembrolizumab Plus Docetaxel for Advanced Non-Small Cell Lung Cancer (PROLUNG) trial randomized 78 patients with histologically confirmed advanced NSCLC in a 1:1 ratio to receive either pembrolizumab plus docetaxel or docetaxel alone from December 2016 through May 2019.InterventionsThe experimental arm received docetaxel on day 1 (75 mg/m2) plus pembrolizumab on day 8 (200 mg) every 3 weeks for up to 6 cycles followed by pembrolizumab maintenance until progression or unacceptable toxic effects. The control arm received docetaxel monotherapy.Main outcomes and measuresThe primary end point was overall response rate (ORR). Secondary end points included progression-free survival (PFS), overall survival, and safety.ResultsAmong 78 recruited patients, 32 (41%) were men, 34 (44%) were never smokers, and 25 (32%) had an EGFR/ALK alteration. Forty patients were allocated to receive pembrolizumab plus docetaxel, and 38 were allocated to receive docetaxel. A statistically significant difference in ORR, assessed by an independent reviewer, was found in patients receiving pembrolizumab plus docetaxel vs patients receiving docetaxel (42.5% vs 15.8%; odds ratio, 3.94; 95% CI, 1.34-11.54; P = .01). Patients without EGFR variations had a considerable difference in ORR of 35.7% vs 12.0% (P = .06), whereas patients with EGFR variations had an ORR of 58.3% vs 23.1% (P = .14). Overall, PFS was longer in patients who received pembrolizumab plus docetaxel (9.5 months; 95% CI, 4.2-not reached) than in patients who received docetaxel (3.9 months; 95% CI, 3.2-5.7) (hazard ratio, 0.24; 95% CI, 0.13-0.46; P < .001). For patients without variations, PFS was 9.5 months (95% CI, 3.9-not reached) vs 4.1 months (95% CI, 3.5-5.3) (P < .001), whereas in patients with EGFR variations, PFS was 6.8 months (95% CI, 6.2-not reached) vs 3.5 months (95% CI, 2.3-6.2) (P = .04). In terms of safety, 23% (9 of 40) vs 5% (2 of 38) of patients experienced grade 1 to 2 pneumonitis in the pembrolizumab plus docetaxel and docetaxel arms, respectively (P = .03), while 28% (11 of 40) vs 3% (1 of 38) experienced any-grade hypothyroidism (P = .002). No new safety signals were identified.Conclusions and relevanceIn this phase 2 study, the combination of pembrolizumab plus docetaxel was well tolerated and substantially improved ORR and PFS in patients with advanced NSCLC who had previous progression after platinum-based chemotherapy, including NSCLC with EGFR variations.Trial registrationClinicalTrials.gov Identifier: NCT02574598.

Project description:BackgroundTo evaluate patient-reported outcomes with ramucirumab plus docetaxel, a regimen which improved progression-free survival in platinum-refractory advanced urothelial carcinoma (aUC).MethodsRANGE-a randomized, double-blinded, phase 3 trial in patients with platinum-refractory aUC. Ramucirumab (10 mg/kg) plus docetaxel (75 mg/m2) or placebo plus docetaxel were administered every 21 days until disease progression or unacceptable toxicity. Patients received maximum 10 cycles of docetaxel. European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) and EuroQoL five-dimensions (EQ-5D-5L) were administered at baseline, start of each cycle, and 30-day follow-up visit. A ≥ 10-point change in QLQ-C30 scores was considered meaningful. Rates of improved/stable scores were compared between treatment arms using Fisher's exact test. Time to deterioration (TtD) was estimated and compared using Kaplan-Meier estimation and log-rank test.ResultsOf the 530 patients, ~ 97% patients in each arm provided baseline QLQ-C30 data. On-treatment compliance was ≥ 88% for first 8 cycles. Mean baseline QLQ-C30 scores were similar between arms, with global quality of life (QoL), fatigue, pain, and insomnia having greatest impairment. Postbaseline rates of improved/stable QLQ-C30 scores were similar between treatment arms except for greater improvement in pain score with ramucirumab. TtD of QLQ-C30 scales favored ramucirumab arm. Baseline EQ-5D-5L index and visual analogue scale scores were similar between arms, followed by relatively stable on-treatment scores. EQ-5D-5L scores worsened at post-discontinuation follow-up visit.ConclusionsRamucirumab plus docetaxel did not negatively impact QoL compared with docetaxel alone in platinum-refractory aUC. Improved TtD and tumor associated rates of pain favored ramucirumab treatment.Clinical trail registrationNCT02426125. https://clinicaltrials.gov/ct2/show/NCT02426125 .

Project description:BACKGROUND AND OBJECTIVE:The economic assessment of immuno-oncology agents in Chinese patients is limited despite a need for new therapies. Nivolumab is the first immune checkpoint inhibitor approved for the second-line treatment of non-small cell lung cancer (NSCLC) in China, and it significantly prolongs overall survival. However, considering the high cost of nivolumab, it is urgent to assess its value in China in terms of both efficacy and cost. The objective of this study was to investigate the cost-effectiveness of nivolumab vs docetaxel in the second-line setting for NSCLC patients from the Chinese healthcare system perspective. METHODS:A Markov model consisting of three health states, was designed to evaluate the lifetime cost and effectiveness of nivolumab vs docetaxel in the second-line treatment of NSCLC patients. Clinical data was derived from the CheckMate 078 phase III clinical trial, which included 504 patients predominantly from China. Parametric survival models to fit and extrapolate survival data were chosen based on clinical rationality, visual fit and statistical goodness-of-fit. Lifetime costs and health outcomes were calculated, and US$28,899 and $63,564 per quality-adjusted life-year (QALY) were selected as the willingness-to-pay (WTP) threshold values for general regions and affluent regions, respectively. One-way and probabilistic sensitivity analyses were undertaken to explore the robustness of the model. Additional subgroup analyses were performed. RESULTS:In base case analysis, Nivolumab yielded an additional 0.24 QALYs, at a cost of $93,307 per QALY. Sensitivity analyses suggested that the results to be most sensitive to the price of nivolumab per kg (mean $60.00; range $26.00-$60.00) and the mean patient weight (65 kg, range 52-78 kg). Utility values in progression-free survival state (mean 0.804; range 0.643-0.965) and overall survival hazard ratio (0.68; 97.7% CI 0.52-0.90) had moderate impact on the model results. Subgroup analyses indicated that nivolumab was most cost-effective for patients who were 65 years of age or older ($85,171/QALY), followed by female patients ($85,273/QALY) and patients with tumor PD-L1 expression at least 1% ($90,309/QALY). CONCLUSIONS:Nivolumab is unlikely to be cost-effective compared with docetaxel for patients with previously treated advanced NSCLC in China. Ensuring that nivolumab is included in the National Reimbursement Drug List (NRDL) may be a valid mean of meeting extensive treatment demands in China.
