Cyclical mastalgia of moderate to severe degree requires systemic drug therapy. Tamoxifen is the drug of choice worldwide. A novel molecule, centchroman/Ormeloxifene, developed in India, was found to be equally effective in previous studies. However, its optimal dose regimen is uncertain. We conducted three-arm randomized controlled trial to compare the effectiveness in relieving breast pain. Group 1 received tamoxifen 10 mg daily, and groups 2 and 3 received centchroman 30 mg twice and 30 mg thrice a week, respectively, for 3 months with a follow-up of 3 more months. Breast pain score, nodularity score, sonographic evaluation of the breasts and ovaries, quality of life scores, and adverse events were recorded. The number of patients enrolled was 32, 31, and 30 in group 1, group 2, and group 3, respectively. All three groups had significant improvement in breast pain scores [group 1 (5 → 2), group 2 (5 → 2), group 3 (6 → 2), p < 0.001)], nodularity scores [group1 (1 → 0), group 2 (1 → 0), group 3 (1 → 0), p < 0.001)] and in the quality of life scores over time. However, no significant differences were observed in-between the groups. Transient ovarian cyst formation and menstrual irregularities were more common with a higher dose of centchroman. Centchroman in the dosages of 30 mg twice or thrice a week is as effective as a daily dose of tamoxifen 10 mg in relieving pain, nodularity, and improving quality of life scores. The dose of centchroman 30 mg twice a week for 12 weeks has the least adverse effects and should be accepted as the optimal dosage regimen. There is a need of further study with a greater number of participants and longer follow-up. Trial registration number: CTRI/2018/02/012043 (Registered on: 21/02/2018). [ABSTRACT FROM AUTHOR]

Purpose: Lutetium-177 prostate-specific membrane antigen-617 (177Lu-PSMA-617) in end-stage metastatic castration-resistant prostate cancer (mCRPC) has reported favourable outcomes. In this study, we aimed to prospectively compare the efficacy and safety of 177Lu-PSMA-617 and docetaxel in chemotherapy-naïve mCRPC patients. Methods: This was a randomized, parallel-group, open-label, phase 2, and non-inferiority trial. Chemotherapy-naïve patients with mCRPC and high PSMA-expressing lesions on 68 Ga-PSMA-11 PET/CT were randomly assigned in 1:1 ratio to 177Lu-PSMA-617 (6.0–7.4 GBq/cycle, every 8 weeks, up to 4 cycles) or docetaxel (75 mg/m2/cycle, every 3 weeks, up to 10 cycles). The primary end-point was best prostate-specific antigen response rate (PSA-RR), defined according to Prostate Cancer Clinical Trials Working Group-3 as proportion of patients achieving ≥ 50% decline in PSA from baseline. Non-inferiority margin of − 15% was pre-specified for PSA-RR. Results: Between December 2019 and March 2021, 40 of the 45 patients assessed for eligibility underwent randomization. Fifteen of 20 patients in 177Lu-PSMA-617 arm and 20/20 patients in docetaxel arm received treatment per protocol. Of these, best PSA-RR in the 177Lu-PSMA-617 arm was 60% (9/15) versus 40% (8/20) in the docetaxel arm. The difference in the PSA-RRs between the two arms was 20% (95% confidence interval, CI: − 12–47, P = 0.25), meeting the pre-specified criterion for non-inferiority in per-protocol analysis. Further, progression-free survival rates at 6 months were 30% and 20% in the 177Lu-PSMA-617 and docetaxel arms respectively (difference 10%, 95% CI: − 18–38, P = 0.50). Overall, treatment-emergent grade ≥ 3 adverse events occurred less frequently with 177Lu-PSMA-617 than with docetaxel (6/20, 30% versus 10/20, 50%, respectively, P = 0.20). Quality-of-life outcomes improved significantly in 177Lu-PSMA-617 arm compared to docetaxel arm (P < 0.01). Conclusion: 177Lu-PSMA-617 was demonstrated to be safe and non-inferior to docetaxel in the treatment of mCRPC and could, thus, be potentially employed earlier in the disease course rather than being solely reserved for advanced end-stage disease.

Objective: The present study aimed to evaluate the efficacy and safety of aripiprazole once-monthly (AOM) compared to oral aripiprazole in treating acute schizophrenia. Methods: This randomized, double-blind, non-inferiority study recruited patients from 15 trial sites across China from May 2017 to April 2019. Patients with an acute psychotic episode received AOM at 400 mg or oral aripiprazole at 10–20 mg for 12 weeks. The primary and secondary efficacy endpoints were the difference in scores from baseline to week 10, as assessed on the Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impressions—Severity (CGI-S) scores, respectively. Results: A total of 436 patients were randomized. Among them, 159/218 (72.9%) and 165/218 (75.7%) in the AOM and oral aripiprazole groups completed 10 weeks of treatment, respectively. The least-squares (LS) mean changes from baseline to endpoint (week 10) in PANSS were − 33.6 for the AOM group and − 34.8 in the oral aripiprazole group, respectively, with a difference of − 1.2 (95% CI: − 4.1, 1.7). The non-inferiority margin of AOM to oral aripiprazole was − 4.1, which was above the lower limit of the pre-defined margin. The altered CGI-S score was − 2.2 and − 2.3 in the AOM and oral aripiprazole groups, respectively. The incidence of treatment-emergent adverse events (TEAEs) was similar in both groups. The rate of discontinuation due to TEAEs was 2.3% and 3.2% in the AOM and oral aripiprazole groups, respectively. Conclusions: This study confirmed the efficacy and safety of AOM for the treatment of Chinese patients with acute schizophrenia. The non-inferiority of AOM to oral aripiprazole was established, with comparable efficacy and tolerability. These findings suggested that AOM could be used as a treatment option for patients experiencing an acute episode of schizophrenia. Trial registration: ClinicalTrials.gov identifier: NCT03172871.
