The FACT-GP5 as a global tolerability measure: responsiveness and robustness to missing assessments.

PURPOSE: The Functional Assessment of Cancer Therapy item (FACT-GP5) has the potential to provide an understanding of global treatment tolerability from the patient perspective. Longitudinal evaluations of the FACT-GP5 and challenges posed by data missing-not-at-random (MNAR) have not been explored. Robustness of the FACT-GP5 to missing data assumptions and the responsiveness of the FACT-GP5 to key side-effects are evaluated. METHODS: In a randomized, double-blind study (NCT00065325), postmenopausal women (n = 618) with hormone receptor-positive (HR+), advanced breast cancer received either fulvestrant or exemestane and completed FACT measures monthly for seven months. Cumulative link mixed models (CLMM) were fit to evaluate: (1) the trajectory of the FACT-GP5 and (2) the responsiveness of the FACT-GP5 to CTCAE grade, Eastern Cooperative Oncology Group (ECOG) Performance Status scale, and key side-effects from the FACT. Sensitivity analyses of the missing-at-random (MAR) assumption were conducted. RESULTS: Odds of reporting worse side-effect bother increased over time. There were positive within-person relationships between level of side-effect bother (FACT-GP5) and severity of other FACT items, as well as ECOG performance status and Common Terminology Criteria for Adverse Events (CTCAE) grade. The number of missing FACT-GP5 assessments impacted the trajectory of the FACT-GP5 but did not impact the relationships between the FACT-GP5 and other items (except for nausea [FACT-GP2]). CONCLUSIONS: Results support the responsiveness of the FACT-GP5. Generally speaking, the responsiveness of the FACT-GP5 is robust to missing assessments. Missingness should be considered, however, when evaluating change over time of the FACT-GP5. TRIAL REGISTRATION: NCT00065325. TRIAL REGISTRATION YEAR: 2003.

Researchers have been exploring the use of a single question, FACT-GP5 ("I am bothered by side effects of treatment"), as a quick way to learn about drug tolerability from the patients' perspective. This study explores if this single question can capture changes in tolerability during treatment, and if the assessment is missed by patients, whether that impacts the interpretation of tolerability. In our study, we found that the FACT-GP5 can be used to understand how tolerability changes during treatment. Missing assessments of the FACT-GP5 are important to account for when interpreting results. The FACT-GP5 may be a useful question for capturing the patient experience of drug tolerability.

A randomized controlled pilot study of daily intravenous ketamine over three days for treatment-resistant depression.

BACKGROUND: Studies have confirmed the rapid antidepressant action of ketamine in depressive episodes. Nevertheless, a standardized procedure for the delivery of ketamine infusion in individuals suffering from treatment-resistant depression, particularly in terms of infusion frequency and total dosage, remains undetermined. In addition, an efficacious ketamine regimen for persistent pain management involved a continuous 10-day infusion period with no notable adverse effects. Consequently, the primary objective of this study was to evaluate the antidepressant capacity of consecutive ketamine infusions spanning over three successive days, the duration of therapeutic response, and the overall safety profile of the treatment. METHODS: In this randomized controlled trial, participants aged 18-64 with treatment-resistant depression were randomized to receive either intravenous ketamine or midazolam (used as an active placebo) for 40 min daily over three consecutive days. Statistical analysis using repeated measures ANOVA was employed to assess the changes in the total score of the Montgomery-Åsberg Depression Rating Scale (MADRS) and the clinical global impression-Severity from the initial assessment to 10 and 31 days post-infusion. Additionally, the duration of response and remission was evaluated using Kaplan-Meier survival analysis. RESULTS: Out of 33 randomized participants, 20 underwent the treatment as planned. By day 10th, the ketamine group had a mean reduction in MADRS score of 12.55 (95% CI = 6.70-18.09), whereas the midazolam group had a decrease of 17.22 (95% CI = 11.09-23.36). This pattern continued to day 31, with ketamine showing a mean score decrease of 13.73 (95% CI = 7.54-19.91) and midazolam a fall of 12.44 (95% CI = 5.61-19.28). Both treatments were well tolerated, with dissociative symptoms in the ketamine group being temporary and ceasing by the end of each infusion. CONCLUSION: Intravenous ketamine given for three consecutive days did not show a notable antidepressant advantage when compared to the active placebo midazolam, highlighting the need for further research into effective treatments schedules for treatment-resistant depression.

Practical management of oral treprostinil in patients with pulmonary arterial hypertension: Lessons from ADAPT, EXPEDITE, and expert consensus.

BACKGROUND: Oral treprostinil is a prostacyclin analogue approved to treat pulmonary arterial hypertension (PAH) by delaying disease progression and improving exercise capacity. Higher doses of oral treprostinil correlate with increased treatment benefit. Titrations may be challenging due to common side effects of prostacyclin-class therapies. STUDY DESIGN AND METHODS: The multicenter, prospective, real-world, observational ADAPT Registry study followed adult patients with PAH for up to 78 weeks after initiating oral treprostinil (NCT03045029). Dosing, titration, and transitions of oral treprostinil were at the discretion of the prescriber. Patient-reported incidence and treatment of common side effects were collected to understand side effect management and tolerability. Insights from literature and expert recommendations were added to provide a consolidated resource for oral treprostinil use. RESULTS: In total, 139 participants in ADAPT completed ≥1 weekly survey; (median age 60.0 years, 76 % female). Median treatment duration of oral treprostinil was 13.1 months. During early therapy (Months 1-5), 62 % (78/126) of patients reported headache and diarrhea, and 40 % (50/126) reported nausea. At Month 6, many patients who reported side effects during early therapy reported an improvement (61 % headache, 44 % diarrhea, 70 % nausea). Common side effect treatments, including acetaminophen, loperamide, and ondansetron, were effective. Approximately one-quarter of patients reporting the most common side effects were untreated at Month 6. CONCLUSION: Patient selection for, and initiation and titration of, oral treprostinil should be individualized and may include parenteral treprostinil induction-transition for faster titration. Assertive side effect management may help patients reach higher and more efficacious doses of oral treprostinil.

Open Label Pilot of Lorcaserin (a serotonin 2C-receptor agonist) for Cannabis Use Disorder.

Background And Objective: Cannabis Use Disorder (CUD) has no FDA approved treatment. Serotonin-2c (5HT2c) agonists have preclinical and human laboratory evidence for potential efficacy for CUD. We assessed the tolerability and effects of lorcaserin (5HT2c agonist) on CUD. Methods: In a 10-week, open label, uncontrolled trial, the tolerability of lorcaserin was tested in outpatients with CUD. Adverse events (AE) were assessed weekly. Cannabis use was assessed twice weekly by the Timeline follow-back and quantitative urine metabolites. Results: 17 participants enrolled, and 14 received medication. Participants' average age was 35 years; majority were male (N=12). The medication was well tolerated in males. There were no serious adverse events (SAE). The most common AE's were headache/migraine (N=4, all females), anorexia (N=3), and irritability (N=2). Participants decreased their frequency of cannabis use significantly (p < 0.001), adjusted for baseline use. By the end of the trial, participants decreased by 1.76 (SE=0.47) cannabis using days/week. Average daily amount of cannabis and urine THC metabolite levels did not change significantly. Conclusions: Lorcaserin was well tolerated in males but not females suggesting possible sex differences. Future trials of other 5HT2c agonists (lorcaserin was withdrawn at the request of the FDA) should consider longer dose titration phases. Trial Registration: NCT02932215.

The efficacy of pandemic-adjusted family/systemic constellation therapy in improving psychopathological symptoms: A randomized controlled trial.

The aim of this pre-registered (NCT05051462), randomized controlled trial was to investigate the efficacy and safety of a pandemic-adjusted version of family/systemic constellation therapy in the general population. Altogether, 80 individuals were randomized (85% retained; 67.6% women, Mage = 41.9 ± 9.2 years) and followed up 1- and 6 months after participation in the single-day intervention. Numerous indicators of psychopathology and addiction as well as wellbeing were assessed. Members of the intervention group improved significantly in terms of the a priori primary outcome (overall psychopathology: d1-month = 0.41, p1-month = 0.003; d6-month = 0.31, p6-month = 0.028) as well as numerous secondary outcomes (obsession-compulsion, interpersonal sensitivity, anxiety, hostility, phobic anxiety, and paranoid ideation). However, the magnitude of improvements was small and mostly disappeared by 6-months. Further, no significant treatment benefit emerged considering time x group interactions regarding any of the outcomes (although statistical power was low). Due to the significant, pandemic-related deviations from the protocol of the intervention, these results may not be generalizable to systemic constellation interventions in general; instead - considering the previous, more favorable data regarding efficacy/effectiveness and tolerability - they rather call attention to the importance of process-related factors regarding this intervention specifically as well as the potential disadvantages of pandemic-related treatment modifications of in-person (non-virtual) group interventions in general.

First-in-human study to assess the safety, tolerability, and pharmacokinetics of intravenous SHPL-49 following single- and multiple-ascending-dose administration in healthy adults.

SHPL-49 is an innovative glycoside derivative that is synthesized by structural modifications of salidroside，demonstrating therapeutic effects on animal models of ischemia in pre-clinical experiments. A phase I, single-center, randomized, double-blind, placebo-controlled, single and multiple dose administration study of SHPL-49 was conducted in healthy Chinese volunteers. In single-ascending-dose (SAD) study, 32 subjects randomized 6:2 to receive SHPL-49 (30 mg, 75 mg, 150 mg, 300 mg) or placebo with 30 minutes infusion. In multiple-ascending-dose (MAD) study, subjects were randomized 6:2 to receive SHPL-49 (75 mg, 150 mg, 300 mg) or placebo with 30 minutes infusion every 8 h for 7 days. Safety evaluations were conducted throughout the studies. Plasma and urine concentrations of SHPL-49 were detected and its metabolites were identified. Pharmacokinetic parameters were calculated using noncompartmental methods. SHPL-49 was generally safe and well-tolerated at single ascending doses (30-300 mg) and multiple ascending doses (75-300 mg). All adverse events were mild and resolved without any intervention. No serious adverse events were reported. In the SAD study, SHPL-49 exhibited dose-proportional plasma pharmacokinetics, with peak plasma concentration (Cmax) ranging from 673.83 to 6275.00 ng/mL, area under the plasma concentration-time curve (AUC0-t) ranging from 338.57 to 3732.67 h·ng/mL, and elimination half-life (t1/2) ranging from 0.49 to 0.67 h. In the MAD, the exposure was also dose-proportional and there was no significant accumulation following multiple dosing. Four metabolites were identified in urine and plasma. SHPL-49 shows a favorable pharmacokinetic, safety, and tolerability profile in healthy Chinese volunteers following a single- and multiple-ascending- dose administration in this study. For future therapeutic investigations, it is recommended to administer SHPL-49 intravenously at 8-hour intervals with a dosage range of 150-300 mg.

Tolerability of a piezoelectric microneedle electroporator in human subjects.

Electroporation, or the use of electric pulses to facilitate the intracellular delivery of DNA, RNA, and other molecules, is a well-established technique, that has been demonstrated to significantly augment the immunogenicity of DNA/mRNA vaccines and therapeutics. However, the clinical translation of traditional electroporators has been limited due to high costs, large size, complex user operation, and poor tolerability in humans due to nerve stimulation. In prior work, we introduced ePatch: an ultra-low-cost, handheld, battery-free electroporator employing a piezoelectric pulser coupled with a microneedle electrode array that showed enhanced immunogenic responses to an intradermal SARS-CoV-2 DNA vaccine in mice. The current study shifts focus from efficacy to tolerability, hypothesizing that ePatch's microneedle array, which localizes the electric field to the superficial skin strata, will minimize nerve stimulation and improve patient comfort. We tested this hypothesis in 14 healthy adults, monitoring pain and other potential adverse effects associated with electroporation. Compared to the insertion of a traditional hypodermic needle, the ePatch was less painful. Adverse effects such as pain, tenderness, erythema and swelling at the application sites were minimal, transient, and statistically indistinguishable between the experimental and placebo ePatch application, suggesting excellent tolerability towards electroporation. In summary, ePatch has a favorable tolerability profile in humans and offers the potential for the safe use of electroporation in a variety of clinical settings, including DNA and mRNA vaccination.

Blood pressure changes during ketamine infusion for the treatment of depression.

OBJECTIVE: This study aimed to examine blood pressure changes during ketamine infusion for depression and exploring the factors associated with these changes. METHOD: This study is a retrospective chart-review of patients with depression undergoing ketamine infusion at Yale Psychiatry Hospital during a 7-year period. Blood pressure (BP) was recorded every 10 min during the infusion. Surges in systolic and diastolic blood pressure (SBP, DBP), along with severe hypertension events, were analyzed in relation to patient demographics. RESULTS: A total of 138 patients received a total of 2342 infusions. SBP and DBP peaked at 40 min after the start of the infusion with a mean change of 16.0 (SD: 11.2) and 11.0 mmHg (SD: 8.45) respectively. Severe hypertension was observed in 17 patients (12.5%) and 23 infusion sessions (0.98%), occuring more frequently during the first three infusions (43.4%). Age (OR = 1.04 [1.02,1.05], p-value <0.001) was significantly associated with a surge in SBP and all patients with a past medical history of hypertension experienced a BP surge during their infusions. CONCLUSION: Ketamine infusions can cause significant blood pressure increases, particularly in older and hypertensive patients, highlighting the need for careful cardiovascular monitoring to mitigate risks during treatment.

Tolerability of the niraparib individualized starting dose in the PRIMA/ENGOT-OV26/GOG-3012 trial of niraparib first-line maintenance therapy.

PURPOSE: To explore safety and tolerability parameters for the niraparib individualized starting dose (ISD) in patients with newly diagnosed advanced ovarian cancer that responded to platinum-based chemotherapy who participated in the phase 3 PRIMA/ENGOT-OV26/GOG-3012 trial (NCT02655016). METHODS: The PRIMA protocol was amended so newly enrolled patients received an ISD based on baseline body weight/platelet count. In this ad hoc analysis, the timing, duration, and resolution of the first occurrence of common any-grade hematologic (thrombocytopenia, anemia, neutropenia) and nonhematologic (nausea, asthenia/fatigue, constipation, insomnia, hypertension) treatment-emergent adverse events (TEAEs) were evaluated by treatment arm in the ISD safety population (data cutoff, November 17, 2021; median follow-up, 3.5 years). RESULTS: Of 733 randomized patients, 255 were enrolled after the ISD protocol amendment and received ≥ 1 dose of study treatment (niraparib, 169; placebo, 86). In the niraparib arm, median times to first events were 22.0-35.0 days for hematologic TEAEs and 7.0-56.0 days for nonhematologic TEAEs. First events resolved in ≥ 89.8% of patients for hematologic TEAEs; for nonhematologic TEAEs, resolution rates ranged from 55.3% (insomnia) to 86.0% (nausea). Median durations of first hematologic TEAEs were ≤ 16.0 days, but for first nonhematologic TEAEs ranged from 18.0 days (nausea) to 134.0 days (insomnia). CONCLUSION: The niraparib ISD was generally well tolerated and TEAEs were manageable. Common hematologic and nonhematologic TEAEs occurred early and first events of hematologic TEAEs had a short duration (≈ 2 weeks) and a high resolution rate. These findings support close monitoring immediately following niraparib initiation and may help inform patient expectations for niraparib safety.

Considerations when treating influenza infections with oseltamivir.

INTRODUCTION: Since the coronavirus disease 2019-mandated social distancing policy has been lifted worldwide, the circulation of influenza is expected to resume. Currently, oseltamivir is approved as the first-line agent for influenza prevention and treatment. AREAS COVERED: This paper reviews the updated evidence in the pharmacology, resistance mechanisms, clinical pharmacy management, and real-world data on oseltamivir for influenza. EXPERT OPINION: Oseltamivir is an oral prodrug of oseltamivir carboxylate, an influenza A and B neuraminidase inhibitor. Recently, the therapeutic efficacy of oseltamivir has been demonstrated in several trials. Oseltamivir is generally well-tolerated but may lead to neuropsychiatric events and bleeding. Oseltamivir-resistant influenza virus has been associated with the H275Y mutation in the influenza A(H1N1)pdm09 virus, while most strains are still sensitive to oseltamivir. Dose adjustment for oseltamivir should be based on creatinine clearance and body weight in pediatric patients with renal failure. According to real-world data from Nanfang Hospital, the annual number of patients prescribed oseltamivir declined from 35,711 in 2019 to 8,971 in 2020, with marked increases in 2022 (20,213) and 2023 (18,071). Among the 206 inpatients, children aged < 6 years who were treated with oseltamivir had the shortest duration to defervescence.

Tolerability of 2 and 4 mg/kg Dosing Every 12 Hour of a Cannabidiol- and Cannabidiolic Acid-Rich Hemp Extract on Mixed-Breed Dogs Utilized for Teaching in a Closed Colony.

With the increase in popularity of utilizing cannabidiol (CBD) for human ailments, owners are actively interested in the possible utilization of cannabinoid products for their pets. The evaluation of CBD-rich hemp as an anti-anxiolytic, anti-inflammatory, immunomodulator, and anti-epileptic supplement has been assessed in previous studies in dogs, with adverse events such as ataxia or lethargy noted. In this study, the utilization of CBD-rich hemp was assessed at two concentrations to ascertain the impact on behavior as well as the tolerability of the medication given in a typically recommended dose and then twice that dose. Eighteen dogs were utilized in a randomized, double-blinded, placebo-controlled, 3 × 3 designed study. Each group of six dogs was provided placebo, 2 mg/kg, and 4 mg/kg of a cannabidiol/cannabidiolic acid (CBD/CBDA)-rich hemp in two-week intervals with one-week washout periods between each treatment period. Throughout the 10-week treatment period, student evaluations were performed, simulating clients' subjective assessments. Improvements in anxiety-related behavior and adverse events related to lethargy and ataxia were not observed and may indicate that the utilization of CBD-rich hemp products for behavioral changes may require higher dosing to mitigate unwanted behaviors in normal, healthy dogs. Furthermore, serum chemistry and serum cortisol were evaluated after each treatment period showing only a mildly significant increase in serum alkaline phosphatase when dosing at 4 mg/kg every 12 h, which is consistent with previously reported CBD dosing at these higher concentrations. Adverse events associated with CBD/CBDA-rich hemp extract given at 2 and 4 mg/kg every 12 h for two weeks were not reported, suggesting that using CBD-rich hemp in young, healthy dogs was safe during two weeks of treatment.

Effect of Efavirenz on the Pharmacokinetics of SHR6390 in Healthy Volunteers.

Purpose: SHR6390 is an oral, potent and selective small-molecule CDK4/6 inhibitor for the treatment of human breast, ovarian and colon cancer. Previous studies have shown that SHR6390 in combination with rifampicin, a potent inducer of CYP3A4, significantly reduces exposure levels. Therefore, we further investigated the effect of efavirenz, a moderate CYP3A4 inducer, on a single oral dose of SHR6390 in healthy volunteers. Patients and Methods: Twenty healthy subjects were enrolled in this single-center, open, single-dose, self-controlled DDI study. On Day 1, subjects received a single oral dose of 150mg SHR6390; on Day 8-26, subjects received 600 mg efavirenz orally at night, with a single dose of 150 mg SHR6390 on Day 22. Blood samples for pharmacokinetic analyses were collected. Results: The geometric mean ratios of the maximum concentration(Cmax) and the area under the concentration curve from zero to infinity (AUC0-inf) between combination therapy and SHR6390 monotherapy (combination therapy/SHR6390 monotherapy) and their 90% confidence intervals were 0.562 (0.482, 0.654) and 0.328 (0.278, 0.386), respectively. This indicates that the Cmax and AUC0 inf of SHR6390 decreased by approximately 43.8% and 67.2%, respectively. Oral administration of 150 mg SHR6390 alone or together with efavirenz was safe and tolerable in healthy subjects. Conclusion: It is suggested that under the action of the moderate CPY3A4 inducer efavirenz, the exposure AUC of SHR6390 exhibits a moderate level of induction. It is recommended to avoid concomitant administration of moderate inducers of CYP3A4 during treatment with SHR6390.

National patterns of paroxetine use among US Medicare patients from 2015-2020.

Introduction: Paroxetine is an older "selective" serotonin reuptake inhibitor (SSRI) that is notable for its lack of selectivity, resulting in an anticholinergic adverse-effect profile, especially among older adults (65+). Methods: Paroxetine prescription rates and costs per state were ascertained from the Medicare Specialty Utilization and Payment Data. States' annual prescription rate, corrected per thousand Part D enrollees, outside a 95% confidence interval were considered significantly different from the average. Results: Nationally, there was a steady decrease in population-corrected paroxetine prescriptions (-34.52%) and spending (-29.55%) from 2015-2020 but a consistent, five-fold state-level difference. From 2015-2020, Kentucky (194.9, 195.3, 182.7, 165.1, 143.3, 132.5) showed significantly higher prescriptions rates relative to the national average, and Hawaii (42.1, 37.9, 34.3, 31.7, 27.7, 26.6) showed significantly lower prescription rates. North Dakota was often a frequently elevated prescriber of paroxetine (2016: 170.7, 2018: 143.3), relative to the average. Neuropsychiatry and geriatric medicine frequently prescribed the most paroxetine, relative to the number of providers in that specialty, from 2015-2020. Discussion: Despite the American Geriatrics Society's prohibition against paroxetine use in older adults and many effective treatment alternatives, paroxetine was still commonly used in the US in this population, especially in Kentucky and North Dakota and by neuropsychiatry and geriatric medicine. These findings provide information on the specialty types and states where education and policy reform would likely have the greatest impact on improving adherence to the paroxetine prescription recommendations.

Treatment with the SQ tree sublingual immunotherapy tablet is safe and well tolerated in real-life.

BACKGROUND: The SQ tree sublingual immunotherapy (SLIT)-tablet is authorised for treatment of allergic rhinoconjunctivitis with or without asthma in trees of the birch homologous group in 21 European countries. The primary objective of this study was to explore the safety in real-life. METHODS: In a prospective, non-interventional post-authorisation safety study (EUPAS31470), adverse events (AEs) and adverse drug reactions (ADRs) at first administration and follow-up visits, symptoms, medication use, and pollen food syndrome were recorded by physicians in 6 European countries during the first 4-6 months of treatment. RESULTS: ADRs with the SQ tree SLIT-tablet were reported in 57.7% of 1069 total patients (median age 36.0 years, 53.7% female) during the entire observation period (severity, mild-to-moderate: 70.1%, severe: 4.7%, serious: 0.7%) and in 45.9% after first administration. ADRs were not increased with pollen exposure at first administration. With coadministration of the SQ tree and grass SLIT-tablet AEs were reported in 73.8% of patients and in 52.8% with the SQ tree SLIT-tablet alone. Nasal and eye symptoms improved in 86.9% and 80.9% of patients and use of symptomatic medication in 76.0%. PFS with symptoms was reported in 43.0% of patients at baseline and in 4.3% at the individual last visit. CONCLUSIONS: The results of this non-interventional safety study with the SQ tree SLIT-tablet confirm the safety profile from placebo-controlled clinical trials and support effectiveness in real-life according to the published efficacy data. Safety was not impaired by pollen exposure at first administration or co-administration with other SLIT-tablets.

Exploring the pharmacokinetics and tolerability of cyclooxygenase inhibitor ampiroxicam: a phase I study on single and multiple oral doses.

Introduction: Ampiroxicam is a long-acting, non-steroidal anti-inflammatory drug that selectively inhibits human cyclooxygenase, effectively mitigating fever, pain, and inflammation. This study evaluated the drug's tolerability and pharmacokinetics to support personalized dosing strategies. Methods: The study involved healthy participants and focused on the pharmacokinetics of ampiroxicam. Plasma levels of piroxicam, a key metabolite of ampiroxicam, were measured using ultra-performance liquid chromatography. Piroxicam was chosen due to its integral role in ampiroxicam's metabolic pathway. The analytical method underwent rigorous validation to ensure precision and accuracy, addressing potential interference from endogenous plasma substances. Results: Participants received ampiroxicam in single doses (low, medium, and high) and multiple doses. Pharmacokinetic parameters, including AUC0-216, AUC0-∞, and Cmax, exhibited a dose-dependent increase. No significant differences were noted across the dosage groups, and sex-specific differences were minimal, with the exception of mean residence time (MRT) in the multiple-dose group, which appeared influenced by body weight variations. Discussion: The findings affirm the safety and efficacy of ampiroxicam across different dosing regimens, validating its clinical utility and potential for personalized medicine in the treatment of pain and inflammation.

Safety and tolerability of esketamine nasal spray versus quetiapine extended release in patients with treatment resistant depression.

In ESCAPE-TRD (NCT04338321), esketamine nasal spray (NS) significantly increased the probability of remission at Week 8, and of being relapse-free through Week 32 after remission at Week 8, versus quetiapine extended release (XR) in patients with treatment resistant depression (TRD). Here, we explore the time course, burden and consequences of treatment emergent adverse events (TEAEs) in the phase IIIb ESCAPE­TRD trial. Patients with TRD were randomised 1:1 to esketamine NS or quetiapine XR, dosed per label alongside an ongoing selective serotonin reuptake inhibitor/serotonin norepinephrine reuptake inhibitor. In this secondary publication, safety analyses (comprising patients who received ≥1 dose of study treatment) included incidence, severity and durations (Kaplan­Meier method) of TEAEs, and subsequent dispositional changes. P values were not adjusted for multiple testing. 336 patients were randomised to esketamine NS and 340 to quetiapine XR; 334 and 336 received ≥1 dose of study treatment, respectively. TEAEs were significantly more common with esketamine NS than quetiapine XR (91.9 % versus 78.0 %; p < 0.001), but were typically mild/moderate and transient in nature: a greater proportion resolved on the same-day (92.0 % versus 12.1 %) and lead to treatment discontinuation in significantly fewer patients (4.2 % versus 11.0 %, respectively; p < 0.001). The proportion of days spent with TEAEs was significantly lower with esketamine NS than quetiapine XR (median: 11.9 % versus 21.3 %; p < 0.001). Although more frequent with esketamine NS, TEAEs were typically transient and mild, with discontinuation less likely versus quetiapine XR. Data were consistent with established safety profiles, with no new safety signals identified. Alongside greater efficacy, the demonstrably more favourable tolerability profile of esketamine NS versus quetiapine XR further supports its use for TRD.

Efficacy, tolerability, and bone density outcomes of elagolix with add-back therapy for endometriosis-associated pain: 12 months of an ongoing randomized phase 3 trial.

BACKGROUND: Elagolix, an approved oral treatment for endometriosis-associated pain, has been associated with hypoestrogenic effects when used as monotherapy. Hormonal add-back therapy has the potential to mitigate these effects. OBJECTIVE: To evaluate efficacy, tolerability, and bone density outcomes of elagolix 200 mg twice daily with 1 mg estradiol /0.5 mg norethindrone acetate (add-back) therapy once daily compared with placebo in premenopausal women with moderate-to-severe endometriosis-associated pain. STUDY DESIGN: This ongoing, 48-month, phase 3 study consists of a 12-month, double-blind period, with randomization 4:1:2 to elagolix 200 mg twice daily with add-back therapy, elagolix 200 mg twice daily monotherapy for 6 months followed by elagolix with add-back therapy, or placebo. The co-primary endpoints were proportion of patients with clinical improvement (termed "responders") in dysmenorrhea and nonmenstrual pelvic pain at month 6. We report 12-month results on efficacy of elagolix with add-back therapy versus placebo in reducing dysmenorrhea, nonmenstrual pelvic pain, dyspareunia, and fatigue. Tolerability assessments include adverse events and change from baseline in bone mineral density. RESULTS: A total of 679 patients were randomized to elagolix with add-back therapy (n=389), elagolix monotherapy (n=97), or placebo (n=193). Compared with patients randomized to placebo, a significantly greater proportion of patients randomized to elagolix with add-back therapy responded with clinical improvement in dysmenorrhea (62.8% versus 23.7%; P≤.001) and nonmenstrual pelvic pain (51.3% versus 36.8%; P≤.001) at 6 months. Compared with placebo, elagolix with add-back therapy produced significantly greater improvement from baseline in 7 hierarchically ranked secondary endpoints including dysmenorrhea (months 12, 6, 3), nonmenstrual pelvic pain (months 12, 6, 3), and fatigue (months 6) (all P<.01). Overall, the incidence of adverse events was 73.8% with elagolix plus add-back therapy and 66.8% with placebo. The rate of severe and serious adverse events did not meaningfully differ between treatment groups. Study drug discontinuations associated with adverse events were low in patients receiving elagolix with add-back therapy (12.6%) and those receiving placebo (9.8%). Patients randomized to elagolix monotherapy exhibited decreases from baseline in bone mineral density of -2.43% (lumbar spine), -1.54% (total hip), and -1.78% (femoral neck) at month 6. When add-back therapy was added to elagolix at month 6, the change from baseline in bone mineral density remained in a similar range of -1.58% to -1.83% at month 12. However, patients who received elagolix plus add-back therapy from baseline exhibited little change from baseline in bone mineral density (<1% change) at months 6 and 12. CONCLUSION: Compared with placebo, elagolix with add-back therapy resulted in significant, clinically meaningful improvement in dysmenorrhea, nonmenstrual pelvic pain, and fatigue at 6 months that continued until month 12 for both dysmenorrhea and nonmenstrual pelvic pain. Elagolix with add-back therapy was generally well tolerated. Loss of bone mineral density at 12 months was greater in patients who received elagolix with add-back therapy than those who received placebo. However, the change in bone mineral density with elagolix plus add-back therapy was < 1% and was attenuated compared with bone loss observed with elagolix monotherapy.

An experience of using Clozapine in elderly patients with mental disorders.

BACKGROUND: There is little information on using clozapine in elderly patients with mental disorders from India. AIM: To evaluate the sociodemographic and clinical profile of elderly (age ≥ 60 years) patients started on clozapine. METHODOLOGY: The clozapine registry in the department was screened to identify elderly patients who were started on clozapine. Treatment records of these patients were reviewed to extract sociodemographic and clinical details. RESULTS: Out of the available information of 1058 patients in the registry, 42 (3.96 %) were elderly (≥ 60 years) patients. About two-thirds of the patients had treatment resistance, i.e., their psychotic illness had not responded to two adequate trials of antipsychotics, and the second most common indication for starting clozapine was tardive dystonia or tardive dyskinesia (23.8 %). The mean dose of clozapine was 135.89 (SD: 109.6; Range: 37.5-500; median: 87.5) mg/day. The mean duration of clozapine use at the time of data extraction for the study sample was 3.55 (SD: 2.15; Range 0.3-9; median: 3) years. At the last follow-up, about three-fourths of patients were experiencing at least one side effect, with constipation being the most common side effect, followed by sedation, weight gain, and hypersalivation. In only four patients, clozapine was stopped during the follow-up. In terms of effectiveness, majority of the patients were rated as much improved or very much improved on Clinical Global Impression-Improvement subscale. CONCLUSION: Clozapine can be safely used in elderly patients with mental disorders. Hence, clozapine should not be withheld in elderly patients with mental disorders whenever indicated.

Ultra-low-dose continuous combined estradiol and dydrogesterone in postmenopausal women: A pooled safety and tolerability analysis.

Objective: To assess the safety and tolerability of ultra-low dose estradiol and dydrogesterone (E0.5 mg/D2.5 mg) among postmenopausal women. Methods: This pooled analysis of data from three clinical studies assessed the effects of continuous combined ultra-low-dose estradiol and dydrogesterone among postmenopausal women. Participants received E0.5 mg/D2.5 mg or placebo for 13 weeks (double-blind, randomized, European study), E0.5 mg/D2.5 mg or placebo for 12 weeks (double-blind, randomized, Chinese study), or E0.5 mg/D2.5 mg for 52 weeks (open-label, European study). Safety outcomes included treatment-emergent adverse events (TEAEs), treatment-emergent serious adverse events (TESAEs), treatment discontinuation due to a TEAE, and adverse events of special interest (AESIs). Results: Overall, 1027 women were included in the pooled analysis (E0.5 mg/D2.5 mg, n = 736; placebo, n = 291). Mean treatment exposure was 288.9 days in the E0.5 mg/D2.5 mg group and 86.6 days in the placebo group. The proportion of women experiencing ≥1 TEAE was similar in the E0.5 mg/D2.5 mg and placebo groups (50.1% vs 49.5%, respectively). TESAEs occurred in 12 (1.6%) women receiving E0.5 mg/D2.5 mg and 9 (3.1%) women receiving placebo. Discontinuation of study treatment was infrequent in both groups (E0.5 mg/D2.5 mg: 1.5%; placebo: 2.4%). The occurrence of breast pain was more common in the E0.5 mg/D2.5 mg group than in the placebo group (2.0% vs 0.3%) as was uterine hemorrhage (6.5% vs 2.4%). The incidence of acne, hypertrichoses and weight increased was similar between groups. Conclusions: Across three studies, ultra-low-dose estradiol plus dydrogesterone was well tolerated among postmenopausal women, with no increase in TEAEs or TESAEs compared with placebo.
