ABSTRACT

The rising prevalence of obesity is of major concern. There are currently 5 Food and Drug Administration-approved medications for the treatment of obesity: orlistat, phentermine/topiramate, naltrexone/bupropion, liraglutide 3.0 mg, and semaglutide 2.4 mg. Surgical options such as bariatric surgery and endoscopic surgery induce more durable weight loss than pharmacotherapy or lifestyle interventions alone. However, patients often experience weight regain and weight loss plateau after surgery. The addition of multimodal or multihormonal pharmacotherapy is a promising tool to address these challenges. The optimal timing of obesity pharmacotherapy with surgical and endoscopic interventions requires further investigation.

ABSTRACT

The present study aimed to assess the potential effect of vitamin B12 (Vit B12) on cognition impairment caused by nicotine (Nic) cessation in adolescent male rats. Adolescent male rats were categorized into two main groups as vehicle (normal saline, intraperitoneally), and Nic group in which received Nic (2 mg/kg) from 21 to 42 days of ages and then the Nic group were divided into three groups as withdrawal (the animals returned to regular diet without treatment), second and third groups received bupropion (20 mg/kg), and Vit B12 at three different doses including 0.5,1, and 1.5 mg/kg by oral gavage as treatments to attenuate Nic withdrawal symptoms. The last group including normal animals received the highest doses of Vit B12 just in the Nic abstinence period to compare the effect of that with vehicle. In MWM, Vit B12and bupropion increased the time spent in the target quadrant that is strongly associated with spatial memory as well as the more time spent with the NORT. Vit B12 and bupropion modulated both oxidant/antioxidant and inflammatory/anti-inflammatory balance, alongside inhibitory effect on AChE, and GFAP. However, BDNF and amyloid-B showed insignificant difference as compared to Vit B12 and bupropion. Considering the present results and similar related studies, Vit B12 can be introduced as a strong anti-oxidant, and anti-inflammatory agent by which probably improved memory impairment caused by Nic addiction accompanied by withdrawal. Further, other mechanisms including activity reduction of AChE, and GFAP should be considered; however, it needs further investigation and larger-scale evidences.

ABSTRACT

The use of electronic health records has expanded in the past decades, with healthcare entities storing terabytes of patient health data. In this study, we investigated how these databases can be utilized to generate clinically relevant information. We used the Office of Addiction Services and Supports Client Data Systems data merged with the NYS Medicaid Data Warehouse to study the relationship of certain antidepressants on alcohol withdrawal (AW) rates in patients with alcohol dependence (AD). We found that in patients with AD, bupropion was associated with a significantly reduced rate of AW compared to selective serotonin reuptake inhibitors (SSRIs). This may be due to the ability of bupropion to inhibit dopaminergic reuptake. This retrospective study provides the advantage of being faster and less expensive than randomized controlled trials (RCTs).

ABSTRACT

3D printing has been introduced as a novel approach for the design of personalized dosage forms and support patient groups with special needs that require additional assistance for enhanced medication adherence. In this study liquid crystal display (LCD) is introduced for the development of sustained release bupropion.HCl printed tablets. The optimization of printing hydrogel inks was combined with the display of Braille patterns on the tablet surface for blind or visually impaired patients. Due to the high printing accuracy, the Braille patterns could be verified by blind patients and provide the required information. Further characterization revealed the presence of BUP in amorphous state within the photopolymerized resins. The selection of poly(ethylene glycol) (PEG)-diacrylate (PEGDA) of different molecular weights and the presence of surfactants or solubilizers disrupted the resin photopolymerization, thus controlling the BUP dissolution rates. A small batch scale-up study demonstrated the capacity of LCD to print rapidly a notable number of tablets within 24 min.

ABSTRACT

OBJECTIVES: Bupropion is an atypical antidepressant that shows robust efficacy in the regulation of neuropathic pain. Citicoline is a dietary supplement which is used as a neuroprotective agent for central nervous system (CNS) disorders. The probable interaction between bupropion and citicoline on neuropathic pain was assessed in male mice. METHODS: Neuropathic pain was induced by sciatic nerve ligation. Neuropathic pain was examined in nerve-ligated mice using tail-flick and hot-plate tests. RESULTS: The results indicated that intraperitoneal (i.p.) administration of citicoline (50 and 100 mg/kg) induced an anti-nociceptive effect in nerve-ligated animals. Similarly, i.p. injection of bupropion (2.5 and 5 mg/kg) induced anti-nociceptive effects in nerve-ligated mice. Co-administration of different doses of bupropion (2.5 and 5 mg/kg) along with a low dose of citicoline (25 mg/kg) caused an anti-nociceptive effect by enhancement of tail-flick and hot plate latencies. Interestingly, there is an additive effect between bupropion and citicoline upon the induction of the anti-nociceptive effect. CONCLUSIONS: Based on these results, it can be concluded that there is an interaction between bupropion and citicoline upon induction of an anti-nociceptive effect in nerve-ligated mice.

ABSTRACT

OBJECTIVE: The aim of this study was to compare past 12-month use of cigarette smoking cessation aids (e.g., Food and Drug Administration (FDA)-approved cessation products or e-cigarettes for smoking cessation) among people with substance use problems (PWSUPs) who currently smoke to people without substance use problems (SUPs) who currently smoke cigarettes in a nationally representative US sample. METHODS: We used the Population Assessment of Tobacco and Health (PATH) Wave 6 Study [n = 30,516]. Our sample comprised adult (18+) established cigarette smokers (100+ lifetime-sticks with daily/non-daily use) [n = 5,895]. The independent variable was SUP status (no, moderate, and high). The dependent variables were past-year use of: nicotine replacement therapies (NRTs), cessation medications [i.e., varenicline or bupropion], or e-cigarettes [for cigarette cessation and reduction]. Weighted multivariable logistic regression models for each dependent variable examined the associations between SUP status and each cessation aid, adjusting for cigarette dependence, daily cigarette smoking, and demographic factors. RESULTS: Among people who smoke, a higher proportion of respondents with high SUP severity used NRTs, cessation medications, and e-cigarettes for cigarette cessation, respectively (12.3%, 8.4%, 15.7%), compared to those with no/low SUP severity (9.8%, 6.0%, 8.9%). In the multivariable models, respondents with high SUPs had 63% (95% CI:1.16-2.29) higher odds of using e-cigarettes for cessation than those without SUPs. No significant differences were seen between high (vs. no/low SUPs) in the past-year use of NRTs and cessation medications. CONCLUSION: Our findings indicate that cigarette smokers with high SUPs had higher odds of using e-cigarettes for cessation and reduction compared to smokers without SUPs.

ABSTRACT

The noradrenaline transporter (also known as norepinephrine transporter) (NET) has a critical role in terminating noradrenergic transmission by utilizing sodium and chloride gradients to drive the reuptake of noradrenaline (also known as norepinephrine) into presynaptic neurons1-3. It is a pharmacological target for various antidepressants and analgesic drugs4,5. Despite decades of research, its structure and the molecular mechanisms underpinning noradrenaline transport, coupling to ion gradients and non-competitive inhibition remain unknown. Here we present high-resolution complex structures of NET in two fundamental conformations: in the apo state, and bound to the substrate noradrenaline, an analogue of the χ-conotoxin MrlA (χ-MrlAEM), bupropion or ziprasidone. The noradrenaline-bound structure clearly demonstrates the binding modes of noradrenaline. The coordination of Na+ and Cl- undergoes notable alterations during conformational changes. Analysis of the structure of NET bound to χ-MrlAEM provides insight into how conotoxin binds allosterically and inhibits NET. Additionally, bupropion and ziprasidone stabilize NET in its inward-facing state, but they have distinct binding pockets. These structures define the mechanisms governing neurotransmitter transport and non-competitive inhibition in NET, providing a blueprint for future drug design.

ABSTRACT

BACKGROUND: Antidepressants are among the most commonly prescribed medications, but evidence on comparative weight change for specific first-line treatments is limited. OBJECTIVE: To compare weight change across common first-line antidepressant treatments by emulating a target trial. DESIGN: Observational cohort study over 24 months. SETTING: Electronic health record (EHR) data from 2010 to 2019 across 8 U.S. health systems. PARTICIPANTS: 183 118 patients. MEASUREMENTS: Prescription data determined initiation of treatment with sertraline, citalopram, escitalopram, fluoxetine, paroxetine, bupropion, duloxetine, or venlafaxine. The investigators estimated the population-level effects of initiating each treatment, relative to sertraline, on mean weight change (primary) and the probability of gaining at least 5% of baseline weight (secondary) 6 months after initiation. Inverse probability weighting of repeated outcome marginal structural models was used to account for baseline confounding and informative outcome measurement. In secondary analyses, the effects of initiating and adhering to each treatment protocol were estimated. RESULTS: Compared with that for sertraline, estimated 6-month weight gain was higher for escitalopram (difference, 0.41 kg [95% CI, 0.31 to 0.52 kg]), paroxetine (difference, 0.37 kg [CI, 0.20 to 0.54 kg]), duloxetine (difference, 0.34 kg [CI, 0.22 to 0.44 kg]), venlafaxine (difference, 0.17 kg [CI, 0.03 to 0.31 kg]), and citalopram (difference, 0.12 kg [CI, 0.02 to 0.23 kg]); similar for fluoxetine (difference, -0.07 kg [CI, -0.19 to 0.04 kg]); and lower for bupropion (difference, -0.22 kg [CI, -0.33 to -0.12 kg]). Escitalopram, paroxetine, and duloxetine were associated with 10% to 15% higher risk for gaining at least 5% of baseline weight, whereas bupropion was associated with 15% reduced risk. When the effects of initiation and adherence were estimated, associations were stronger but had wider CIs. Six-month adherence ranged from 28% (duloxetine) to 41% (bupropion). LIMITATION: No data on medication dispensing, low medication adherence, incomplete data on adherence, and incomplete data on weight measures across time points. CONCLUSION: Small differences in mean weight change were found between 8 first-line antidepressants, with bupropion consistently showing the least weight gain, although adherence to medications over follow-up was low. Clinicians could consider potential weight gain when initiating antidepressant treatment. PRIMARY FUNDING SOURCE: National Institutes of Health.

ABSTRACT

Importance: Obesity affects approximately 19% of women and 14% of men worldwide and is associated with increased morbidity. Antiobesity medications (AOMs) modify biological processes that affect appetite and significantly improve outcomes, such as type 2 diabetes, hypertension, and dyslipidemia. Observations: AOMs should be administered in combination with lifestyle interventions and can be classified according to their mechanisms of action. Orlistat modifies digestive tract absorption and causes gastrointestinal adverse effects, such as oily fecal spotting and urgency, in more than 25% of patients. Centrally acting drugs, such as phentermine-topiramate and naltrexone-bupropion, regulate appetite in the brain and are associated with constipation in approximately 20% of patients, although the incidence of other adverse effects (eg, paresthesia, nausea) varies by medication. Nutrient-stimulated hormone-based medications, such as liraglutide, semaglutide, and tirzepatide, mimic the actions of enteropancreatic hormones that modify central appetite regulation and provide multiple cardiometabolic weight-loss benefits. Adverse effects of these drugs include nausea (28%-44%), diarrhea (21%-30%), and constipation (11%-24%). The relative potency of adult obesity medications has been studied in meta-analyses. Compared with placebo, orlistat was associated with 3.1% greater weight loss (52 randomized clinical trials [RCTs]; 16 964 participants), phentermine-topiramate was associated with 8.0% greater weight loss (5 RCTs; 3407 participants), naltrexone-bupropion was associated with 4.1% greater weight loss (6 RCTs; 9949 participants), liraglutide was associated with 4.7% greater weight loss (18 RCTs; 6321 participants), semaglutide was associated with 11.4% greater weight loss (5 RCTs; 4421 participants), and tirzepatide 15 mg was associated with 12.4% greater weight loss (6 RCTs; 1972 participants). Conclusion and Relevance: Obesity is associated with increased morbidity. Antiobesity medications are effective adjunctive therapy to lifestyle changes for improved weight loss and health outcomes.

ABSTRACT

Noradrenaline, also known as norepinephrine, has a wide range of activities and effects on most brain cell types1. Its reuptake from the synaptic cleft heavily relies on the noradrenaline transporter (NET) located in the presynaptic membrane2. Here we report the cryo-electron microscopy (cryo-EM) structures of the human NET in both its apo state and when bound to substrates or antidepressant drugs, with resolutions ranging from 2.5 Å to 3.5 Å. The two substrates, noradrenaline and dopamine, display a similar binding mode within the central substrate binding site (S1) and within a newly identified extracellular allosteric site (S2). Four distinct antidepressants, namely, atomoxetine, desipramine, bupropion and escitalopram, occupy the S1 site to obstruct substrate transport in distinct conformations. Moreover, a potassium ion was observed within sodium-binding site 1 in the structure of the NET bound to desipramine under the KCl condition. Complemented by structural-guided biochemical analyses, our studies reveal the mechanism of substrate recognition, the alternating access of NET, and elucidate the mode of action of the four antidepressants.

ABSTRACT

BACKGROUND: This overview of reviews aims to identify evidence on the benefits (i.e. tobacco use abstinence and reduction in smoking frequency) and harms (i.e. possible adverse events/outcomes) of smoking cessation interventions among adults aged 18 years and older. METHODS: We searched Medline, Embase, PsycINFO, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, the CADTH Health Technology Assessment Database and several other websites for grey literature. Searches were conducted on November 12, 2018, updated on September 24, 2020, with publication years 2008 to 2020. Two reviewers independently performed title-abstract and full-text screening considering pre-determined inclusion criteria. Data extraction and quality assessments were initially completed by two reviewers independently (i.e. 73% of included studies (n = 22)) using A Measurement Tool to Assess Systematic Reviews-2 (AMSTAR 2), and the remainder done by one reviewer and verified by another due to resources and feasibility. The application of Grading of Recommendations Assessment, Development and Evaluation (GRADE) was performed by one independent reviewer and verified by another. RESULTS: A total of 22 Cochrane systematic reviews evaluating the impact of smoking cessation interventions on outcomes such as tobacco use abstinence, reduction in smoking frequency, quality of life and possible adverse events were included. Pharmaceutical (i.e. varenicline, cytisine, nicotine replacement therapy (NRT), bupropion) and behavioural interventions (i.e. physician advice, non-tailored print-based self-help materials, stage-based individual counselling, etc.) showed to have increased smoking cessation; whereas, data for mobile phone-based interventions including text messaging, hypnotherapy, acupuncture, continuous auricular stimulation, laser therapy, electrostimulation, acupressure, St John's wort, S-adenosyl-L-methionine (SAMe), interactive voice response systems and other combination treatments were unclear. Considering harms related to smoking cessation interventions, small/mild harms (i.e. increased palpitations, chest pain, nausea, insomnia, headache) were observed following NRT, varenicline and cytisine use. There were no data on harms related to behavioural therapies (i.e. individual or group counselling self-help materials, internet interventions), combination therapies or other therapies (i.e. laser therapy, electrostimulation, acupressure, St John's wort, SAMe). CONCLUSION: Results suggest that pharmacological and behavioural interventions may help the general smoking population quit smoking with observed small/mild harms following NRT or varenicline. Consequently, evidence regarding ideal intervention strategies and the long-term impact of these interventions for preventing smoking was unclear.

ABSTRACT

INTRODUCTION: Major Depressive Disorder (MDD) is a common mental health disorder marked by sadness, hopelessness, and anhedonia. Various therapies exist, but their effectiveness is limited. Dextromethorphan hydrobromide combined with bupropion hydrochloride (Auvelity®) is a recently approved alternative for treating this condition in adults. AREAS COVERED: This review summarizes the neurobiology of major depression and delves into the pharmacology, efficacy, safety, and tolerability of dextromethorphan plus bupropion in adult patients. It is based on observational studies, clinical trials, and other secondary studies obtained through systematic literature searches. EXPERT OPINION: The combination of bupropion and dextromethorphan as a new pharmacotherapy for mental health is an interesting addition to the treatment options that can be used for MDD. The combination can be used in a range of scenarios, including as a first line therapy, as a second option when a patient has failed to achieve remission with a serotonin targeting agent, and for treatment resistant depression. Further research for other indications, including addiction disorders, may provide exciting results. Although a new combination, clinicians will be very familiar with both agents, increasing their acceptability. This pharmacotherapy also may bring increased impetus for discovering other combinations that may have beneficial synergistic effects.

ABSTRACT

AIMS: Major depressive disorder (MDD) is a prevalent, chronic disorder. Auvelity (dextromethorphan-bupropion) is a novel, oral N-methyl-D-aspartate (NMDA) receptor antagonist and sigma-1 receptor agonist approved (August 2022) by the FDA for treating MDD in adults. This is the first analysis on real-world Auvelity usage in the United States. METHODS: Adult patients initiating Auvelity in the Symphony IDV databases by September 2023 were identified (index date: the first Auvelity claim). Patients had continuous eligibility over the 12-month pre-index period and ≥1 MDD diagnosis (ICD-10-CM codes: F32.*, F33.*) over the 5-year pre-index period. Demographic and clinical characteristics, comorbidities, prior MDD-related medications, and Auvelity initiation status were assessed. RESULTS: This analysis included 22,288 patients with MDD treated with Auvelity (mean age 45.1 years; 68.1% women); 40.0% lived in the South and 58.5% had commercial insurance. Comorbidities included mental health disorders (53.5%; 47.6% had anxiety disorders). Overall, 83.7% of the patients had received treatment with selective serotonin reuptake inhibitors (SSRIs; 54.9%), the norepinephrine-dopamine reuptake inhibitor (NDRI [bupropion]; 40.4%), and/or serotonin-norepinephrine reuptake inhibitors (SNRIs; 35.9%) over the 12-month pre-index period. The last MDD-related treatment prior to Auvelity comprised SSRI (22.4%), SNRI (13.2%), and NDRI (12.8%) monotherapies; 294 (1.3%) patients received esketamine. In total, 6,418 (28.8%) patients initiated Auvelity as monotherapy vs 15,870 (71.2%) as an add-on; Auvelity was most frequently added to an SSRI alone (10.7%) or SNRI alone (6.5%). A total of 2,254 (10.1%) patients initiated Auvelity without prior treatment in the 12-month pre-index period. LIMITATIONS: Incomplete data due to reporting; diagnoses captured subject to coding error; and limited generalizability to other populations. CONCLUSIONS: Using a large demographically distributed claims database, 22,288 patients with MDD initiated Auvelity within a year of its approval; 10.1% were treatment-naïve and 28.8% initiated Auvelity as monotherapy. Most patients had mental health-related comorbidities and attempted various MDD-related treatments prior to Auvelity.


Major depressive disorder (medical terminology for "depression") is a common medical condition that makes people feel persistently sad or hopeless, affecting their ability to handle daily activities. Effective treatment, which may include medication, is crucial for improving their quality of life. This study explores how people in the United States use a new medication called Auvelity to treat depression. Researchers reviewed the medical records of over 22,000 adults with depression, looking at their age, gender, location, type of health insurance, other health conditions, and use of other depression medications. The study focused on people who started using Auvelity in the first year after its Food and Drug Administration (FDA) approval. On average, Auvelity users were 45 years old. They lived across various regions of the US, had different types of health insurance, and over two-thirds were women. Many Auvelity users had other mental health disorders, including anxiety. Most had tried different types of medications for depression in the previous year, while about 10% had not used any other depression medicines in the previous year. When starting Auvelity, almost one-third of patients used it as their only depression medicine. Over two-thirds of patients started Auvelity alongside another depression medicine. Initial Auvelity prescriptions were issued by a diverse range of medical professionals, including psychiatrists, primary care physicians, nurse practitioners, and physician assistants. These findings provide valuable insights into how this new medicine is used in real life and can inform treatment decisions of healthcare providers who help manage depression in their patients.

ABSTRACT

OBJECTIVE: This study provides three prevalence-based metrics of potential harm, the fatal toxicity index (FTI), serious morbidity index (SMI) and healthcare utilization index (HUI) for fourteen of the most prescribed antidepressants in the US. METHOD: For the years 2013-2020, adverse events for single drug exposures were obtained from the National Poison Data System. Prescription estimates were taken from the Agency for Healthcare Research and Quality's Medical Expenditure Survey. 95% confidence intervals were calculated using a Poisson distribution. Chi-square testing was used where significance was not clear. RESULTS: SSRIs and SNRIs had the lowest overall indices (FTI 0.02-0.26). Bupropion's FTI (0.27-0.43) was not statistically significantly different from that of imipramine (FTI 0-1.3, p = .62) or nortriptyline (FTI 0.25-0.78, p = .22), though its SMI and HUI were significantly greater. There was a statistically significant difference in all indices between TCAs (p < .0047). The difference between the FTI of all SSRIs did not remain significant after correction (p = .045). CONCLUSION: SSRIs and SNRIs are safer than alternative agents on all measures. Bupropion exposure was as likely to cause mortality, and more likely to cause morbidity or require treatment in a healthcare facility, than TCAs nortriptyline and imipramine.

ABSTRACT

Importance: Significant evidence gaps exist regarding the safety of smoking cessation pharmacotherapies during pregnancy, especially for the risk of congenital malformations. Consequently, professional bodies advise against the use of varenicline and bupropion and recommend caution with nicotine replacement therapy (NRT). Contemporary estimates of the use of smoking cessation pharmacotherapies during pregnancy are lacking. Objective: To quantify the proportion of individuals using prescribed smoking cessation pharmacotherapies during pregnancy and during the first trimester specifically, in 4 countries. Design, Setting, and Participants: This retrospective, population-based cohort study used linked birth records, hospital admission records, and dispensing records of prescribed medications from all pregnancies resulting in birth between 2015 and 2020 in New South Wales, Australia; New Zealand; Norway; and Sweden. Data analyses were conducted in October and November 2023. Exposure: Prescribed smoking cessation pharmacotherapy use (varenicline, NRT, and bupropion) during pregnancy was defined as days' supply overlapping the period from date of conception to childbirth. Main Outcomes and Measures: Prevalence of use among all pregnancies and pregnancies with maternal smoking were calculated. Among women who used a pharmacotherapy, the proportion of women with use during the first trimester of pregnancy was also calculated. Results: Among 1 700 638 pregnancies in 4 countries, 138 033 (8.1%) had maternal smoking and 729 498 (42.9%) were younger than 30 years. The prevalences ranged from 0.02% to 0.14% for varenicline, less than 0.01% to 1.86% for prescribed NRT, and less than 0.01% to 0.07% for bupropion. Among pregnant individuals who smoked, use of pharmacotherapies was up to 10 times higher, with maximum prevalences of 1.25% for varenicline in New South Wales, 11.39% for NRT in New Zealand, and 0.39% for bupropion in New Zealand. Use in the first trimester occurred among more than 90% of individuals using varenicline, approximately 60% among those using NRT, and 80% to 90% among those using bupropion. Conclusions and Relevance: In this cohort study of pregnant individuals in 4 high-income countries, the low prevalence of varenicline and bupropion use during pregnancy and higher prevalence of NRT use aligned with current clinical guidelines. As most use occurred in the first trimester, there is a need for evidence on the risk of congenital malformations for these medications.

ABSTRACT

INTRODUCTION: Diabetes and depression are among the 10 biggest health burdens globally. They often coexist and exhibit a strong bidirectional relationship. Depression leads to decreased adherence to self-care activities. This impacts glycaemic control and worsens type 2 diabetes mellitus (T2D). Both conditions have a synergistic effect and lead to greater complications, hospitalisations, healthcare expenditure and a worse quality of life. There is no consensus on managing people with comorbid T2D and depression. Bupropion is an efficacious antidepressant with many properties suitable for T2D with depression, including a favourable metabolic profile, persistent weight loss and improvement in sexual dysfunction. We will assess the efficacy and safety of add-on bupropion compared with standard care in people with T2D and mild depression. This study can give valuable insights into managing the multimorbidity of T2D and depression. This can help mitigate the health, social and economic burden of both these diseases. RESEARCH DESIGN AND METHODS: This cross-over randomised controlled trial will recruit people with T2D (for 5 years or more) with mild depression. They will be randomised to add-on bupropion and standard care. After 3 months of treatment, there will be a washout period of 1 month (without add-on bupropion while standard treatment will continue). Following this, the two arms will be swapped. Participants will be assessed for glycosylated haemoglobin, adherence to diabetes self-care activities, lipid profile, urine albumin-to-creatinine ratio, autonomic function, sexual function, quality of life and adverse events. ETHICS AND DISSEMINATION: The Institutional Ethics Committee at All India Institute of Medical Sciences, Jodhpur has approved this study (AIIMS/IEC/2022/4172, 19 September 2022). We plan to disseminate the research findings via closed group discussions at the site of study, scientific conferences, peer-reviewed published manuscripts and social media. TRIAL REGISTRATION NUMBER: CTRI/2022/10/046411.

ABSTRACT

BACKGROUND: Female cancer survivors often experience estrogen-deprivation symptoms, which may lead to decreases in sexual desire, vulvovaginal health (lubrication, dryness, discomfort), and sexual satisfaction. Interventions are needed to address these concerns. AIM: The objective of this secondary analysis was to determine if women with higher (better) scores on the Female Sexual Function Index (FSFI) lubrication and pain subscales reported higher desire scores based on treatment with bupropion vs placebo. METHODS: Participants were part of NRG Oncology's NRG-CC004 (NCT03180294), a randomized placebo-controlled clinical trial evaluating bupropion (150 vs 300 mg) to improve sexual desire in survivors of breast or gynecologic cancer. All participants with baseline data from the FSFI lubrication, pain, and desire subscales with 5- and/or 9-week data were analyzed. The FSFI subscale scores were correlated using Spearman correlation coefficients. Logistic regression was used to determine associations between FSFI desire and other FSFI subscales while accounting for treatment arm and other covariates. OUTCOMES: The primary outcome of NRG Oncology's NRG-CC004 (NCT03180294) randomized phase II dose-finding trial was change from baseline to 9 weeks on the FSFI desire subscale score. Similar to the parent study, the primary outcome for this ancillary data study was the FSFI desire subscale score at 5 and 9 weeks. RESULTS: Overall, 230 participants completed the FSFI at baseline and 189 at 9 weeks. The strongest correlations were between lubrication and pain at baseline (all participants, rho = 0.77; bupropion arms, rho = 0.82), week 5 (all participants, rho = 0.71; bupropion arms, rho = 0.68), and week 9 (all participants, rho = 0.75; bupropion arms, rho = 0.78), and the weakest correlations were between desire and pain. In patients in the treatment arms there were no interactions between lubrication or pain.The impact of various covariates on the FSFI score for desire at 9 weeks demonstrated that participants of non-White race (odds ratio [OR], 0.42; 95% CI, 0.21-0.81; P = .010), with a high lubrication score (OR, 0.36; 95% CI, 0.21-0.61; P = .0002), with a high pain score (less pain) (OR, 0.50; 95% CI, 0.29-0.87; P = .014), or with prior pelvic surgery (OR, 0.38; 95% CI, 0.23-0.63; P = .0002) had lower odds of having low desire. CLINICAL IMPLICATIONS: Acute estrogen-deprivation symptoms should be addressed prior to sexual desire intervention. STRENGTHS AND LIMITATIONS: This secondary analysis was not powered to examine all variables. CONCLUSION: Lubrication and pain were predictors of low desire. Therefore, vulvovaginal atrophy and associated genitourinary symptoms of menopause such as vaginal dryness and dyspareunia should be addressed prior to or in parallel with interventions for sexual desire.
