Mantle cell lymphoma (MCL) is a mature B-cell neoplasm with a high initial response rate followed almost invariably by relapse. Here we report the pooled data from 2 studies, BGB-3111-AU-003 and BGB-3111-206, to explore the efficacy of zanubrutinib monotherapy in relapsed/refractory (R/R) MCL. A total of 112 patients were included. Median follow-up durations were 24.7 and 24.9 months for BGB-3111-AU-003 and BGB-3111-206, respectively. Overall response rate (ORR) and complete response (CR) rate were 84.8% and 62.5%, and median duration of response, progression-free survival (PFS) and overall survival (OS) were 24.9, 25.8 and 38.2 months, respectively. After weighting, the PFS (median: NE vs. 21.1 months, P = 0.235) and OS (median: NE vs. 38.2 months, P = 0.057) were similar but numerically better in the second-line than later-line group. Zanubrutinib was well-tolerated with treatment discontinuation and dose reduction for adverse events in 12.5% and 2.7% of patients, respectively. Hypertension, major hemorrhage and atrial fibrillation/flutter rates were 11.6%, 5.4% and 1.8%, respectively. Zanubrutinib is efficacious in R/R MCL, with a favorable safety profile.

RationaleLong-acting injectable (LAI) paliperidone palmitate 1-month formulation (PP1M) has demonstrated acceptable tolerability and favorable clinical outcomes in Western and Asian patients with schizophrenia. Hence, analysis of the outcomes of long-term PP1M treatment specifically in Chinese patients is of interest.ObjectiveThe aim of this study is to evaluate the long-term safety and efficacy of PP1M treatment in Chinese patients with schizophrenia.MethodsIn this 25-week, open-label, Phase IV study, patients (18–65 years) diagnosed with schizophrenia and having a baseline Positive and Negative Syndrome Scale (PANSS) total score of 60–120 (inclusive) were enrolled. All patients received injections of PP1M 150 mg eq. (day 1) and 100 mg eq. (day 8), followed by a flexible once-monthly maintenance dosing (75, 100, or 150 mg eq.).ResultsOf the 353 patients, 234 (66.3%) completed the study treatment (mean age, 31.1 years; 52.7% men). The PANSS total score (primary end point) improved significantly over the 6-month treatment period (mean [standard deviation] change from baseline to end of treatment, −27.2 [18.30]; P<0.0001). The Clinical Global Impressions-Severity and Personal and Social Performance scores (secondary end points) also improved significantly (P<0.0001). At 6 months, PP1M had a positive impact on medication satisfaction, adherence, and increased preference for LAIs. Treatment-emergent adverse events (TEAEs) were reported by 181 (51.3%) patients (TEAEs ≥5%: extrapyramidal disorder [15.3%], akathisia [10.5%], blood prolactin increase [8.8%], insomnia [5.4%]). A total of 8 deaths were reported, including 4 completed suicides.ConclusionLong-term treatment with PP1M was efficacious, and no new safety concerns were identified in Chinese patients with schizophrenia. Overall, the results were comparable with observations from previous studies.

Background:Limited data are available to help identify patients with schizophrenia who are most likely to benefit from long-acting injectable antipsychotics.Aim:To investigate the efficacy of long-acting injectable antipsychotic paliperidone palmitate one-month formulation for preventing relapses, factors influencing time to first relapse, and the effect of different antipsychotic adherence levels on time to first relapse in Chinese patients with schizophrenia.Methods:This was a post-hoc analysis from an open-label, single-arm study of stable patients (Positive and Negative Syndrome Scale total score <70; n=367) receiving paliperidone palmitate one-month formulation at the end of an acute 13-week treatment phase, who entered a naturalistic one-year follow-up period, either continuing with flexibly dosed paliperidone palmitate one-month formulation (75–150 mg eq.) or switching to another antipsychotic(s).Results:There were 362/367 patients (age=31.4±10.75 years) included in the analysis of time to first relapse (primary outcome) and 327/362 patients (39/327, poor antipsychotic adherence (<80%)) willing to receive antipsychotics were included in the exposure/adherence analysis. Overall, 84.6% (95% confidence interval=79.2–88.7) patients remained relapse-free. Poor adherence during follow-up (hazard ratio=2.97, 95% confidence interval=1.48–5.98, p=0.002) and frequent hospitalizations in the previous year (hazard ratio=1.29, 95% confidence interval=1.02–1.62, p=0.03) were associated with a significant risk of shorter time to first relapse in the univariate analysis. In patients with poor adherence, ‘no use’ (hazard ratio=13.13, 95% confidence interval=1.33–129.96, p=0.03) and ‘interrupted use’ (hazard ratio=11.04, 95% confidence interval=1.03–118.60, p=0.047) of paliperidone palmitate one-month formulation (vs continued use) showed a significantly higher risk of relapse; this was not observed in patients with good (≥80%) antipsychotic adherence. No new safety concerns were identified.Conclusion:Continued use of paliperidone palmitate one-month formulation/long-acting injectable antipsychotic was effective in preventing schizophrenia relapses, especially in patients with suboptimal antipsychotic adherence.

BackgroundPrevious meta-analyses have compared paliperidone extended-release (ER) tablets with other antipsychotics, but none have involved Chinese patients or studies from People’s Republic of China. Further, the results of these meta-analyses may not be applicable to Chinese patients. In the present study, we evaluated the efficacy, safety, and acceptability of paliperidone ER compared with other second-generation antipsychotics (SGAs) for Chinese patients with schizophrenia.MethodsRandomized controlled studies of paliperidone ER and other SGAs as oral monotherapy in the acute phase treatment of schizophrenia were retrieved from Medline, Embase, and the Cochrane Library (CENTRAL), as well as from Chinese databases including the China National Knowledge Infrastructure, Wanfang, and VIP Information/Chinese Scientific Journals Database. We pooled data on response rates, chance of withdrawal due to adverse events, probability of adverse events, and odds of withdrawal for any reason.ResultsFifty randomized controlled trials were identified. The response rate for paliperidone ER was significantly higher than that of other pooled SGAs (risk ratio [RR] 0.83, 95% confidence interval [CI] 0.72–0.96) and ziprasidone (RR 0.57, 95% CI 0.39–0.82). Paliperidone ER significantly reduced the chance of withdrawal due to adverse events and the chance of any adverse events compared with other pooled SGAs (RR 0.32, 95% CI 0.17–0.58 and RR 0.88, 95% CI 0.79–0.97) and risperidone (RR 0.31, 95% CI 0.14–0.67 and RR 0.70, 95% CI 0.57–0.86). The incidence of extrapyramidal symptoms on paliperidone ER was comparable with other pooled SGAs (RR 0.94, 95% CI 0.66–1.35) and significantly lower than that of risperidone (RR 0.56, 0.41–0.77) but higher than that of olanzapine (RR 1.88, 95% CI 1.05–3.36). Paliperidone ER was superior to other pooled SGAs (RR 0.32, 95% CI 0.21–0.49 and RR 0.50, 95% CI 0.35–0.72) and olanzapine (RR 0.23, 95% CI 0.15–0.33 and RR 0.33, 95% CI 0.23–0.47) as far as weight gain and somnolence were concerned. Further, prolactin-related adverse events caused by paliperidone ER were comparable with other pooled SGAs (RR 1.30, 95% CI 0.73–2.33), but outnumbered those caused by olanzapine (RR 7.53, 95% CI 2.05–27.71).ConclusionPaliperidone ER is efficacious, safe, and well accepted when compared with other pooled SGAs for the treatment of Chinese patients with schizophrenia.
