dasotraline (SEP-225289) / Sumitomo Pharma - LARVOL DELTA

A Physiologically-Based Pharmacokinetic Model to Characterize Dasotraline Pharmacokinetics and CYP-mediated Drug-Drug Interactions. (PubMed, Drug Metab Bioanal Lett) - "The PBPK model developed via the middle-out approach provides a quantitative tool to predict CYP-mediated DDI with dasotraline as either a victim or a perpetrator and the impact of polymorphic CYP2B6 on dasotraline PK. This model may aid in optimizing dosing strategies to minimize the risks associated with CYP-mediated interactions and significant accumulation following repeated dosing."

Structural basis for pharmacotherapeutic action of triple reuptake inhibitors. (PubMed, Nat Commun) - "Tesofensine and dasotraline stabilize DAT in an outward-facing conformation, while centanafadine, ansofaxine, and nefazodone capture the inward-facing conformation. Notably, ansofaxine binds at a location which is much closer to the intracellular membrane surface. Through extensive structural analysis, we establish a comprehensive blueprint for the association of these TRIs, which is crucial for future drug development aimed at achieving potent antidepressant with fewer side effect."

Estimating heterogeneity of treatment effect in psychiatric clinical trials. (PubMed, J Psychiatr Res) - "For example, heterogeneous response was found in a trial of venlafaxine for depression (peHTE = 0.034), and two trials of dasotraline for binge eating disorder (Phase 2, peHTE = 0.002; Phase 3, 4 mg peHTE = 0.011; Phase 3, 6 mg peHTE = 0.003). Significant response heterogeneity was detected in other datasets as well, often despite no difference in variance between placebo and drug arms. The implications of eHTE as a clinical trial outcomes, independent of central tendency of the group, is considered and the importance of the eHTE method and results for drug developers, providers, and patients is discussed."

Pharmacotherapies for Binge Eating Disorder: Systematic Review and Network Meta-Analysis. (PubMed, Obes Rev) - "Topiramate, lisdexamfetamine, and dasotraline show significant potential in treating BED. However, the landscape of pharmacotherapy for BED lacks robust evidence and methodological standardization. Larger trials with expanded sample sizes and using validated scales are needed to guide clinical practice for this highly prevalent and damaging disorder."

Safety and efficacy of dasotraline for patients with attention deficit/hyperactivity disorder: a systematic review and meta-analysis of 1594 patients including GRADE qualifications. (PubMed, Psychopharmacology (Berl)) - "dasotraline showed a significant improvement in the primary outcome (MD -2.65, 95% CI [-4.14 to -1.17], P= 0.0004 The results showed that dasotraline demonstrated a significant improvement in both primary and secondary outcomes, establishing its efficacy as a novel treatment for ADHD symptoms. However, mild to moderate side effects were observed."

Efficacy and safety of monoamine reuptake inhibitors in attention deficit hyperactivity disorder: A Bayesian network meta-analysis. (PubMed, J Psychiatr Res) - "The drugs showing significant reduction on the ADHD rating scale as compared to placebo are bupropion (SMD: 0.33; 95%CrI: 0.60,-0.059), dasotraline(SMD: 0.49; 95%CrI: 0.82,-0.16), venlafaxine(SMD: 0.71; 95%CrI: 1.3,-0.15), viloxazine(SMD: 0.45; 95%CrI: 0.77,-0.12). Other drugs (centanafadine, duloxetine, edivoxetine, reboxetine, tipepidine, vortioxetine) were no better than placebo in reducing symptom severity of ADHD...Among all, duloxetine (OR:15; 95%CrI:1.8130) showed significantly more treatment-emergent adverse events than methylphenidate. In conclusion, venlafaxine, viloxazine, and bupropion are the most efficacious MRIs for ADHD symptom reduction as compared to placebo with high certainty of evidence."

The role of adrenergic neurotransmitter reuptake inhibitors in the ADHD armamentarium. (PubMed, Expert Opin Pharmacother) - "The authors conducted a PubMed literature search using the following key words: 'ADHD' AND 'adrenergic reuptake inhibitors' OR 'nonstimulants' OR 'atomoxetine' OR 'Viloxazine' OR 'Dasotraline' OR 'Centanafadine' OR 'PDC-1421' OR 'Reboxetine' OR 'Edivoxetine' OR 'Bupropion' OR 'Venlafaxine' OR 'Duloxetine.' They reviewed FDA fact sheets of available medications for safety/tolerability studies and reviewed published clinical studies of these medications for treatment of ADHD. Adrenergic neurotransmitter reuptake inhibitors fit the diverse needs of children and adolescents with ADHD with 1) poor tolerability to stimulants (e.g. due to growth suppression, insomnia, rebound irritability, co-morbid depression, anxiety and tic disorders, substance abuse or diversion concerns), 2) cardiac risks, and/or 3) need for extended duration of action. Their differences in receptor..."

Using Class-Effect Queries Defined on Established Pharmacological Classes in Clinical Development of Novel Compounds (ASCP 2024) - "These results further substantiate this approach to summarize adverse events in clinical trials, where the cumulative burden of class-specific risks describes the emerging safety profile of an investigational new drug in clinical development, relative to reactions anticipated for 1 drugs in an established pharmacological class. From the AE profile, dasotraline is closest to NRI compared to other three drug classes it is compared to. A weighted combination of % safety subjects at EBGM ≥ 3, % AEs not found in class effect query and AE with highest EBGM in the class effect query is a viable model to quantify the association of an investigational compound with established drug classes."

Novel algorithm using incidence and duration to calculate adverse event prevalence in randomized controlled trials (ECNP 2022) - "AE Prevalence curves were calculated for pooled drug treatment arms of RCTs in various psychiatric and neurological disorders (insomnia, partial onset seizures, ADHD/BED, bipolar disorder and schizophrenia) and for various drug treatments (eszopiclone, eslicarbazepine, dasotraline, lurasidone and ulotaront) and compared with their respective placebo arms. Whereas the benefits of drug treatment are evaluated by dedicated efficacy measures analyzed using common statistical Methods, use of analysis Methods beyond standard incidence tables for AE data in RCTs are less commonplace. Combining AE incidence with duration offers a new way to evaluate risk to patients for treatment vs. non-treatment."

Prospects for new drugs to treat binge-eating disorder: Insights from psychopathology and neuropharmacology. (PubMed, J Psychopharmacol) - "Lisdexamfetamine (LDX) is the only approved BED drug treatment...The evidence supports the hypothesis that BED is an impulse control disorder with similarities to ADHD, including responsiveness to catecholaminergic drugs, for example LDX and dasotraline...(2) The analysis revealed a large number of pharmacological mechanisms are unlikely to be productive in the search for effective new BED drugs. (3) The most promising areas for new treatments for BED are drugs, which augment noradrenergic and dopaminergic neurotransmission and/or those which are effective in ADHD."

Understanding the Polypharmacological Profiles of Triple Reuptake Inhibitors by Molecular Simulation. (PubMed, ACS Chem Neurosci) - "In this study, the solved X-ray crystallographic structure of hSERT in complex with escitalopram was used as a basis for modeling nine complexes of three representative TRIs (SEP225289, NS2359, and EB1020) bound to their corresponding targets. Furthermore, the combined protein-ligand interaction fingerprint and residue energy contribution analysis indicated that several conserved and nonconserved "Warm Spots" such as S149, V328, and M427 in hDAT, F317, F323, and V325 in hNET and F335, F341, and V343 in hSERT were responsible for the TRI-binding selectivity. These findings provided important information for rational design of a single drug with better polypharmacological profiles through modulating multiple targets."

[VIRTUAL] Evidence-based therapeutic management of binge-eating disorder (EPA 2021) - "Lisdexamfetamine dimesylate is the only FDA approved drug for this indication, as dasotraline was rejected by FDA and its research discontinued by the manufacturer. Fluoxetine, sertraline, escitalopram, duloxetine, bupropion, atomoxetine, reboxetine, armodafinil, disulfiram, baclofen, zonisamide, lamotrigine, topiramate, samidorphan, liraglutid, and orlistat need more trials in order to validate their efficacy, especially on long term.  Conclusions There is only one drug currently FDA approved for this indication, lisdexamfetamine, and a number of psychotherapies, with CBT and IPT being the most supported by evidence."
