aprepitant and Carcinoma--Non-Small-Cell-Lung

Pruritus is one of the most common and challenging side effects of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) and has impaired patients' quality of life and treatment compliance. Our study evaluated the efficacy and safety of aprepitant in managing EGFR-TKIs-related pruritus.. This randomized, double-blind, placebo-controlled study was conducted between December 2016 and August 2020 in China. Patients were eligible if they were 18 years or older and had histologically confirmed locally advanced or metastatic non-small cell lung cancer (NSCLC) with first onset of moderate to severe pruritus during EGFR-TKI treatment.. A total of 130 eligible patients were randomly assigned to aprepitant (n = 65) or desloratadine (n = 65) groups. The median (interquartile range [Q1, Q3]) age was 63 (54, 70) years, and 79 (60.8%) were women. Mean visual analog scale scores at baseline were 6.35 (95% confidence interval [CI], 5.89-6.82) in the aprepitant group and 5.94 (95% CI, 5.56-6.32) in the desloratadine group. After 1 week of treatment, 33 (53.2%) patients responded to aprepitant, which was significantly higher than that of 14 (23.7%) patients responded to desloratadine (p = .001). Moreover, patients in the aprepitant group had a significantly shorter response time than patients in the desloratadine group (mean [days], 13.39 [95% CI, 11.08-15.70] vs. 16.67 [95% CI, 14.19-19.13], p = .04). The most frequent drug-related adverse events in aprepitant group and desloratadine were constipation and dry mouth, and all adverse events were grade 1-2.. To the authors' knowledge, this is the first study to prospectively present that aprepitant elicited a better and faster response and mild toxicity for managing EGFR-TKI induced pruritus than desloratadine..

Although cough is a common and distressing symptom in patients with lung cancer, there is almost no evidence to guide treatment. Aprepitant, a centrally acting neurokinin-1 inhibitor, significantly decreased cough frequency in a pilot study.. Patients with advanced lung cancer and cough lasting over 2 weeks despite a cough suppressant were randomized 1:1 to aprepitant 125 mg orally on day 1 and then 80 mg orally on days 2 to 7 with physician's choice of antitussive; or to physician's choice of antitussive alone. Evaluation was at baseline and on days 3, 7, 9, and 12. The primary end point was subjective cough improvement on day 9, measured by the Visual Analog Scale and Manchester Cough in Lung Cancer Scale. Secondary end points included quality of life (QoL) as measured by the European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire and the EORTC Lung Cancer-Specific Quality of Life Questionnaire and toxicity.. Between 2017 and 2018, 128 patients were randomized. Median baseline cough duration was 90 days. Mean Visual Analog Scale scores (in mm) at baseline and day 9 were 68 and 39 in the aprepitant arm and 62 and 49 in the control arm, respectively (P < .001); mean Manchester Cough in Lung Cancer Scale scores at baseline and day 9 were 33 and 23 in the aprepitant arm and 30 and 25 in the control arm, respectively (P < .001). Overall QoL was not significantly different between the two arms; however, aprepitant led to a significant improvement in the cough-specific QoL domain (P = .017). Aprepitant did not increase severe adverse events.. Aprepitant led to a significant improvement in cough in advanced lung cancer, without increasing severe side effects..

Chemotherapy-induced nausea and vomiting is a challenging issue. Although aprepitant is sometimes used as a therapeutic option in patients receiving moderately emetogenic chemotherapy, the potential benefit of sequential addition of aprepitant to dexamethasone and a 5-hydroxytryptamine-3 (5-HT3) receptor antagonist during the second cycle of carboplatin-based chemotherapy remains unclear. Chemo-naïve patients with advanced non-small cell lung cancer (NSCLC) who received carboplatin-based chemotherapy were treated with doublet antiemetic therapy with dexamethasone and a 5-HT3 receptor antagonist during the first cycle of chemotherapy. Aprepitant was then added during the second cycle of chemotherapy. The primary endpoint was overall complete response rate, defined as no vomiting and no rescue therapy during the 120 h after administration of chemotherapy. Sixty-seven patients were enrolled, 63 of whom were eligible after two cycles of chemotherapy. The overall complete response rate was significantly improved in the second cycle [87.3 %, 95 % confidence interval (CI) 76.5-94.4 %] compared with the first cycle (65.1 %, 95 % CI 52.0-76.7 %; p < 0.001). Improvement was observed in the delayed phase, but not in the acute phase. Subsequent addition of aprepitant significantly improved the overall complete response rate in NSCLC patients receiving a second cycle of carboplatin-based chemotherapy.

Chemotherapy-induced nausea and vomiting (CINV) is an unanswered problem in cancer therapy. We evaluated the efficacy and safety of triple antiemetic therapy with aprepitant, a 5-hydroxytryptamine-3 (5-HT(3)) receptor antagonist, and dexamethasone in patients with advanced non-small-cell lung cancer (NSCLC) who received carboplatin-based first-line chemotherapy.. Chemotherapy-naïve patients with NSCLC were enrolled in this randomized phase-II study. Patients were randomized to standard antiemetic therapy with a 5-HT(3) receptor antagonist and dexamethasone, and aprepitant add-on triple antiemetic therapy. The primary endpoint was the complete response rate (no vomiting and no rescue therapy) during the 120 h post-chemotherapy.. A total of 134 patients were assigned randomly to the aprepitant group or the control group. The aprepitant group and the control group showed an overall complete response rate of 80.3% (95% confidence interval (CI), 69.2-88.1%) and 67.2% (95% CI, 55.3-77.2%; odds ratio (OR), 0.50; 95% CI, 0.22-1.10; p = 0.085), respectively. Among patients taking carboplatin and pemetrexed, adding aprepitant significantly improved the complete response rate in the overall phase (83.8% in the aprepitant group and 56.8% in the control group; OR, 0.26; 95% CI, 0.08-0.70; p < 0.01) and the delayed phase (86.5% in the aprepitant group and 59.1% in the control group; OR, 0.23; 95% CI, 0.07-0.65; p < 0.01).. Carboplatin-based chemotherapy has considerable emetic potential. Triple antiemetic therapy with aprepitant, a 5-HT(3) receptor antagonist, and dexamethasone improved the control of CINV prevention in patients receiving carboplatin and pemetrexed chemotherapy.

This study was conducted to determine the pharmacokinetics of aprepitant and dexamethasone as well as the relationship between the plasma concentration of substance P and nausea/vomiting in Japanese cancer patients.. After administration of aprepitant (125/80 mg group [10 patients]: 125 mg on day 1 and 80 mg on days 2-5; 40/25 mg group [10 patients]: 40 mg on day 1 and 25 mg on days 2-5) and dexamethasone (6 mg on day 1 and 4 mg on days 2 and 3 in the 125/80 mg group, and 8 mg on day 1 and 6 mg on days 2 and 3 in the 40/25 mg group) to Japanese cancer patients receiving at least moderately emetogenic antitumor agents, the plasma concentrations of aprepitant, dexamethasone, and substance P were measured.. All of 20 patients were treated with the highly emetogenic agent cisplatin (≥70 mg/m(2)). The C(max) and AUC(0-24 h) of aprepitant in Japanese cancer patients were similar with those in non-Japanese patients. The clearance of dexamethasone in the 125/80 mg group was approximately one-half of that previously determined in the absence of aprepitant. The substance P concentration in plasma significantly increased only in patients with delayed nausea/vomiting.. This study demonstrated similar plasma pharmacokinetics of aprepitant in Japanese and non-Japanese, the validity of reducing dexamethasone dose, and the existence of increased plasma substance P concentration in patients receiving highly emetogenic cisplatin-based chemotherapy.

Aprepitant is used with dexamethasone and 5-HT. Urinary 11β-hydroxytestosterone (11β-OHT)/testosterone concentration ratio and plasma 4β-hydroxycholesterol (4β-OHC) concentrations were measured before and after cisplatin treatment (days 1, 4, and 8). CYP3A5 was genotyped, and plasma aprepitant concentrations were measured on day 4 to examine its influence on CYP3A endogenous markers.. The urinary 11β-OHT/testosterone concentration ratio in the 35 patients included in this study increased by 2.65-fold and 1.21-fold on days 4 and 8 compared with day 1, respectively. Their plasma 4β-OHC concentration increased by 1.46-fold and 1.66-fold, respectively. The mean plasma aprepitant concentration on day 4 was 1,451 ng/mL, which is far lower than its inhibitory constant. The allele frequencies of CYP3A5*1 and CYP3A5*3 were 0.229 and 0.771, respectively. In patients with the CYP3A5*1 allele, the plasma 4β-OHC concentration was significantly lower at baseline but more potently increased with chemotherapy.. CYP3A activity was significantly induced from day 4 to day 8 in patients receiving cisplatin and three antiemetic drugs.

Aprepitant prevents chemotherapy-induced nausea and vomiting (CINV) in carboplatin-containing chemotherapy. However, it is unknown whether aprepitant salvage therapy after the development of emesis is as effective as adding prophylactic aprepitant to doublet therapy with dexamethasone and a 5-HT

Although substantial progress has been made in the treatment of non-small-cell lung cancer (NSCLC) patients with immune checkpoint inhibitors (ICIs), severe immune-related adverse events (irAEs) sometimes occur. Here, we report a case of severe refractory pruritus after Stevens-Johnson syndrome (SJS) in a patient with NSCLC treated with nivolumab. The patient was a 76-year-old Japanese woman with advanced NSCLC treated with nivolumab. After the second dose, she experienced severe rash with mucous involvement. We diagnosed SJS and started 50mg of oral prednisolone (1mg/kg). The rash completely resolved after prednisolone was started, but we could not manage the severe pruritus with emollients, antihistamines, and steroids. Finally, we administered aprepitant, an oral neurokinin-1 receptor antagonist, for her refractory pruritus. Her symptoms improved within 5days. Severe refractory pruritus can arise from ICIs, and aprepitant may be a useful treatment.

Approximately one half of cancer patients experience nausea or vomiting during chemotherapy containing high-dose cisplatin, despite the use of a corticosteroid and 5-hydroxytryptamine(3) (5-HT(3)) receptor antagonists. The addition of aprepitant, a neurokinin 1 receptor antagonist, improves control of emesis by a further 15-20%, and improves late phase symptoms (>24 h after chemotherapy). The cornerstone of standard first line lung cancer chemotherapy is high-dose cisplatin. Our experience with aprepitant in the chemotherapy of 10 lung cancer patients is described, who reported more than one episode of vomiting caused by chemotherapy despite the use of ondansetron previously. Aprepitant prevented acute and late phase oncoming vomiting in all 10 patients and acute and late phase nausea in 9 of the 10 patients. According to our experience on a limited number of patients, aprepitant may be of clinical benefit in the supportive treatment of lung cancer, in achieving better quality of life during chemotherapeutic cycles in these patients.
