A randomized, phase 2 study comparing pemetrexed plus best supportive care versus best supportive care as maintenance therapy after first-line treatment with pemetrexed and cisplatin for advanced, non-squamous, non-small cell lung cancer.

ABSTRACT: Maintenance therapy for non-small cell lung cancer (NSCLC) aims to extend disease control after first-line chemotherapy with active and well-tolerated agents. The utility of continuation maintenance therapy requires further research.This multicenter, randomized, phase 2 study compared continuation maintenance therapy with pemetrexed (500?mg/m2 every 21?days) and best supportive care (BSC) versus BSC alone in patients with advanced, non-squamous NSCLC who had not progressed after 4?cycles of induction chemotherapy with pemetrexed (500?mg/m2) and cisplatin (75?mg/m2). The primary endpoint was progression-free survival (PFS) from randomization, was analyzed using a Cox model, stratified for the tumor response at the end of induction therapy, at a one-sided alpha of 0.2. Secondary endpoints: response and disease control rates, overall survival (OS), one year survival rates, and treatment-emergent adverse events (TEAEs).A total of 106 patients commenced induction therapy, of whom 55 patients were randomized to maintenance pemetrexed/BSC (n?=?28) or BSC (n?=?27). Although the median PFS time for maintenance phase for both arms was 3.2?months, the one-sided p-value for the PFS HR comparison was less than the prespecified limit of 0.2 (HR?=?0.76, two-sided 95% confidence interval [CI]: 0.42 to 1.37; one-sided p-value?=?0.1815), indicating that PFS was sufficiently long in the pemetrexed/BSC arm to warrant further investigation. Similar PFS results were observed for the overall study period (induction plus maintenance) and when the PFS analysis was adjusted for sex, baseline disease stage, and the ECOG PS prior to randomization. The median OS for the maintenance phase was 12.2?months (95%CI: 5.6 to 20.6) for the pemetrexed/BSC arm and 11.8?months (95% CI: 6.3 to 25.6) for BSC arm. The one-year survival probabilities were similar for both arms for the maintenance phase and the overall study period. Both the induction and continuation maintenance therapies were generally well-tolerated, and similar proportion of patients in each arm experienced at least 1 grade 3/4 TEAE (pemetrexed/BSC, 17.9%; BSC, 18.5%).Continuation pemetrexed maintenance therapy resulted in promising PFS with an acceptable safety profile in a Middle Eastern population with advanced non-squamous NSCLC and is worthy of further investigation.NCT00606021.

Project description:ObjectivesSpasticity is an incurable chronic condition, and patients with spasticity frequently experience symptoms such as muscle stiffness, restricted mobility, fatigue, spasms, and pain. The study objective was to assess the cost-effectiveness of abobotulinumtoxinA plus best supportive care compared with best supportive care alone for the early treatment of adult lower limb spasticity following an acute event (e.g. stroke or traumatic brain injury), from an Australian payer perspective.MethodsUsing clinical data from published pivotal trials, an economic model based on a Markov model was developed to capture changes in treatment costs, healthcare resource use costs, functional outcomes, and health-related quality of life over a lifetime horizon. Scenario analyses and a probabilistic sensitivity analysis were conducted to explore the uncertainty in the model parameters and assumptions used in the base case.ResultsAbobotulinumtoxinA plus best supportive care was cost-effective versus best supportive care, yielding an incremental cost-effectiveness ratio of $35,721 per quality-adjusted life year gained. Sensitivity analyses confirm the robustness of the base case, with most results remaining below the commonly acceptable cost-effectiveness willingness-to-pay threshold of $75,000 per quality-adjusted life year for cost-effectiveness in Australia. Inputs and assumptions that produced the top four highest incremental cost-effectiveness ratios include the application of different health resource utilisation source, short time horizon, unweighted regression analyses to determine regression probabilities, and no stopping rule. AbobotulinumtoxinA plus best supportive care has a 74% probability of being cost-effective compared with best supportive care alone at the willingness to pay threshold.ConclusionAbobotulinumtoxinA plus best supportive care treatment is cost-effective in Australia for the management of adult lower limb spasticity in patients treated within 2 years of an acute event.

Project description:ImportanceCapecitabine maintenance therapy improves survival outcomes in various cancer types, but data are limited on the efficacy and safety of capecitabine maintenance therapy in metastatic nasopharyngeal carcinoma (NPC).ObjectiveTo investigate the efficacy and safety of capecitabine maintenance therapy in metastatic NPC.Design, setting, and participantsThis randomized phase 3 clinical trial was conducted at Sun Yat-sen University Cancer Center from May 16, 2015, to January 9, 2020, among 104 patients with newly diagnosed metastatic NPC who had achieved disease control after 4 to 6 cycles of induction chemotherapy with paclitaxel, cisplatin, and capecitabine. The final follow-up date was May 30, 2021. All efficacy analyses were conducted in the intention-to-treat population.InterventionsEligible patients were randomly assigned (1:1) to receive either capecitabine maintenance therapy (1000 mg/m2 orally twice daily on days 1-14) every 3 weeks plus best supportive care (BSC) (capecitabine maintenance group) or BSC alone after 4 to 6 cycles of induction chemotherapy.Main outcomes and measuresProgression-free survival (PFS). Secondary end points were objective response rate, duration of response, overall survival, and safety.ResultsThis study included 104 patients (84 men [80.8%]; median age, 47 years [IQR, 38-54 years]), with 52 assigned to the capecitabine maintenance group and 52 assigned to the BSC group. After a median follow-up of 33.8 months (IQR, 22.9-50.7 months), there were 23 events (44.2%) of progression or death in the capecitabine maintenance group and 37 events (71.2%) of progression or death in the BSC group. Median PFS survival was significantly higher in the capecitabine maintenance group (35.9 months [95% CI, 20.5 months-not reached]) than in the BSC group (8.2 months [95% CI, 6.4-10.0 months]), with a hazard ratio of 0.44 (95% CI, 0.26-0.74; P = .002). Higher objective response rates and longer median duration of response were observed in the capecitabine maintenance group (25.0%; 40.0 months) compared with the BSC group (objective response rate, 25.0% [n = 13] vs 11.5% [n = 6]; and median duration of response, 40.0 months [95% CI, not reached-not reached] vs 13.2 months [95% CI, 9.9-16.5 months]). The most common grade 3 or 4 adverse events during maintenance therapy were anemia (6 of 50 [12.0%]), hand-foot syndrome (5 of 50 [10.0%]), nausea and vomiting (3 of 50 [6.0%]), fatigue (2 of 50 [4.0%]), and mucositis (2 of 50 [4.0%]). No deaths in the maintenance group were deemed treatment-related.Conclusions and relevanceIn this phase 3 randomized clinical trial, capecitabine maintenance therapy significantly improved PFS for patients with newly diagnosed metastatic NPC who achieved disease control after capecitabine-containing induction chemotherapy. Capecitabine exhibited manageable toxic effects.Trial registrationClinicalTrials.gov Identifier: NCT02460419.
