Non-steroidal anti-inflammatory drugs induce severe hematologic toxicities in lung cancer patients receiving pemetrexed plus carboplatin: A retrospective cohort study.

ABSTRACT:

Purpose

As the major toxicity induced by pemetrexed plus carboplatin is severe hematologic toxicities, the aim of this study was to determine the risk factors for severe hematologic toxicities in lung cancer patients.

Methods

We retrospectively investigated data from lung cancer patients who had received pemetrexed plus carboplatin, with or without bevacizumab. This observational study was carried out at Ehime University Hospital using electronic medical records dating from July 2009 to March 2015. Severe hematologic toxicities were defined as grade 3 or 4, according to the Common Terminology Criteria for Adverse Events, version 4.0.

Results

Forty-two patients were included in the study. The incidence of grade 3 or 4 hematologic toxicities during the first cycle of chemotherapy and during all cycles was 19.0% and 16.1%, respectively. Multivariate time-depend generalized estimating equations logistic regression analysis revealed that regular use of non-steroidal anti-inflammatory drugs (NSAIDs) was significantly associated with an increased risk of severe hematologic toxicities during all cycles (adjusted odds ratio (OR): 8.32, 95% confidence interval (CI): 1.27-54.38; p = 0.03), whereas creatinine clearance of <45 mL/min was not significantly associated with an increased risk of severe hematologic toxicities during all cycles (adjusted OR: 0.91, 95% CI: 0.25-3.34; p = 0.88).

Conclusions

The results suggest that severe hematologic toxicities in patients receiving carboplatin-based pemetrexed may be significantly induced by the inhibition of renal tubular pemetrexed secretion through drug-drug interactions between NSAIDs and pemetrexed rather than through glomerular filtration of pemetrexed, even with moderate to sufficient renal function.

Project description:BackgroundMany physicians consider platinum-doublet chemotherapy inappropriate for elderly patients, regardless of their medical fitness.ObjectiveThis was a retrospective subgroup analysis of data from a multicenter, randomized, phase III clinical trial evaluating pemetrexed + carboplatin versus docetaxel + carboplatin in elderly chemo-naive patients with advanced, nonsquamous non-small cell lung cancer (NSCLC).MethodsData from elderly patients (aged ≥65 years and ≥70 years) were evaluated using the same statistical methods as those used in patients aged <70 years and qualified intent-to-treat (Q-ITT) populations. The primary objective of the clinical trial was comparison of pemetrexed + carboplatin with docetaxel + carboplatin in terms of survival without grade 3 or 4 toxicity in chemo-naive NSCLC patients.ResultsThe ≥65- and ≥70-year age groups had 68 and 37 patients, respectively. Among patients aged ≥65 years, the adjusted hazard ratio (HR) for survival without grade 3-4 toxicity (HR 0.40, 95 % confidence interval [CI] 0.23-0.70) favored pemetrexed + carboplatin; this was similar to the HRs in patients aged ≥70 years (HR 0.43, 95 % CI 0.20-0.92), patients aged <70 years (HR 0.44, 95 % CI 0.32-0.62), and the Q-ITT population (HR 0.45, 95 % CI 0.34-0.61). The median values for overall survival (OS) and progression-free survival (PFS) were similar across all age-group subsets and the Q-ITT population. The HRs for OS and PFS were similar for all age-group subsets, except for the ≥70-year age group, which favored pemetrexed + carboplatin to a greater extent. The toxicity profile was similar across age groups, with the exception of diarrhea, mucosal inflammation, and grade 3-4 neutropenia and leukopenia, which were slightly more common in elderly patients in both treatment arms. Between-arm differences in the toxicity profiles for the ≥65-, ≥70- and <70-year age subgroups were similar to those in the Q-ITT population. There were no on-study deaths or unexpected toxicities.ConclusionThe benefits of pemetrexed + carboplatin were maintained, and toxicity was manageable in both elderly subgroups. The favorable risk-benefit profile of pemetrexed + carboplatin makes it an appropriate first-line treatment option for elderly patients with advanced nonsquamous NSCLC.

Project description:ImportanceFew clinical trials have been specifically designed for elderly patients with advanced non-small cell lung cancer (NSCLC), and the anticipated increase in the number of such patients has prompted a search for new treatment options that provide a greater palliative benefit.ObjectiveTo determine whether treatment with carboplatin plus pemetrexed followed by pemetrexed maintenance is noninferior compared with docetaxel monotherapy with regard to overall survival (OS) for elderly patients with advanced nonsquamous NSCLC.Design, setting, and participantsThis open-label, multicenter, noninferiority phase 3 randomized clinical trial was conducted at 79 institutions in Japan. Cytotoxic chemotherapy-naive patients with advanced nonsquamous NSCLC, an Eastern Cooperative Oncology Group performance status of 0 or 1, and age of 75 years or older were enrolled between August 2013 and February 2017. Data were analyzed from November 2018 to February 2019.InterventionsPatients were randomized to receive either docetaxel monotherapy (60 mg/m2) every 3 weeks or 4 cycles of carboplatin (area under the curve of 5) plus pemetrexed (500 mg/m2) administered every 3 weeks followed by maintenance therapy with the same dose of pemetrexed for 3 weeks.Main outcomes and measuresThe primary end point was OS analyzed on an intention-to-treat basis with a noninferiority margin of 1.154 for the upper limit of the 95% CI of the hazard ratio (HR) estimated with a stratified Cox regression model.ResultsOf the 433 enrolled patients, 250 (57.7%) were male, and the median (range) age was 78 (75-88) years. The median OS was 15.5 months (95% CI, 13.6-18.4) in the docetaxel group (n?=?217) and 18.7 months (95% CI, 16.0-21.9) in the carboplatin-pemetrexed group (n?=?216), with a stratified HR for OS of 0.850 (95% CI, 0.684-1.056; P for noninferiority?=?.003). Progression-free survival was also longer in the carboplatin-pemetrexed group (unstratified HR, 0.739; 95% CI, 0.609-0.896). Compared with those in the docetaxel group, those in the carboplatin-pemetrexed had lower rates of leukopenia (60 of 214 [28.0%] vs 147 of 214 [68.7%]) and neutropenia (99 of 214 [46.3%] vs 184 of 214 [86.0%]) of grade 3 or 4 and of febrile neutropenia (9 of 214 [4.2%] vs 38 of 214 [17.8%]) and higher rates of thrombocytopenia (55 of 214 [25.7%] vs 3 of 214 [1.4%]) and anemia (63 of 214 [29.4%] vs 4 of 214 [1.9%]) of grade 3 or 4. Dose reductions were less frequent with carboplatin-pemetrexed.Conclusion and relevanceCarboplatin-pemetrexed treatment followed by pemetrexed maintenance is a valid option for first-line treatment of elderly patients with advanced nonsquamous NSCLC.Trial registrationUniversity Hospital Medical Information Network Clinical Trials Registry Identifier: UMIN000011460.
