Meta-analysis of Subjects from 4 RCTs Supports Potential of Enobosarm to Optimize Weight Loss (OBESITY WEEK 2024) - "In this meta-analysis of older obese subgroup, enobosarm reduced fat mass while preserving lean mass with weight loss of mostly fat. This supports the potential for enobosarm when combined with a GLP-1 RA to also preserve muscle, while preferentially reducing fat resulting in a higher quality weight loss obese patients. A Phase 2b randomized controlled trial is currently underway to evaluate the safety and efficacy of enobosarm in older patients receiving a GLP-1 RA for weight loss."

In Vitro and In Vivo Human Metabolism of Ostarine, a Selective Androgen Receptor Modulator and Doping Agent. (PubMed, Int J Mol Sci) - "The production of cyanophenol-sulfate might participate in the mechanism of ostarine liver toxicity. We suggest ostarine-glucuronide (C25H22O9N3F3, diagnostic fragments at m/z 118, 185, and 269) and hydroxybenzonitrile-ostarine-glucuronide (C25H22O10N3F3, diagnostic fragments at m/z 134, 185, and 269) in non-hydrolyzed urine and ostarine and hydroxybenzonitrile-ostarine (C19H14O4N3F3, diagnostic fragments at m/z 134, 185, and 269) in hydrolyzed urine as markers to document ostarine intake in doping."

The disordering effect of SARMs on a biomembrane model. (PubMed, Phys Chem Chem Phys) - "Here, we report significant information related to the changes that ostarine, ligandrol, andarine, and cardarine produce in the thermodynamic properties of a lipid biomembrane model. By employing theoretical calculations, we gained insights into the possible electrostatic interactions between SARMs and phospholipid molecules, enhancing our understanding of the driving forces behind the interactions of SARMs with lipid membranes. Overall, this investigation provides relevant knowledge related to the biophysical-chemical effects that SARMs produce in biomembrane models and could be of practical reference for promising applications of SARMs in medicine and sport."

Atossa Therapeutics Announces Updated Protocol for Clinical Trial Evaluating (Z)-Endoxifen in Combination with Abemaciclib (VERZENIO) in Women with ER+/HER2- Breast Cancer (GlobeNewswire) - "Atossa Therapeutics, Inc...today announced protocol changes in the previously initiated study to evaluate Atossa’s proprietary (Z)-endoxifen in combination with abemaciclib (VERZENIO)...The study is investigating the combination as a neoadjuvant treatment in women with newly diagnosed Estrogen Receptor positive (ER+) / Human Epidermal Growth Factor Receptor 2 negative (HER2-) breast cancer...Based on accumulating data from the ongoing Phase 2 EVANGELINE study, the dose of (Z)-endoxifen in the combination study has been increased from 40 mg to 80 mg once daily. The change in study dose was determined following a review of safety, efficacy and pharmacokinetic (PK) data from participants currently enrolled in the 80 mg PK run-in cohort of the EVANGELINE study."

Meta-analysis supports the potential for enobosarm when combined with a GLP-1 RA may preserve muscle, while preferentially reducing fat resulting in a higher quality weight loss in overweight and obese patients. A Phase 2b randomized controlled trial is currently underway to evaluate enobosarm in older patients receiving a GLP-1 RA for weight loss."

Double-Blind, Multiple Ascending Dose, Safety, Pharmacokinetic and Body Composition Study of Enobosarm in Healthy Young and Older Men (AACE 2024) - "While enobosarm was associated with positive body composition changes in men regardless of age, older men with lower lean mass and higher fat mass at baseline appear more likely to have greater benefit from enobosarm therapy. An ongoing randomized controlled Phase 2b trial is enrolling to evaluate the safety and efficacy of enobosarm as a treatment to augment fat loss and to prevent muscle loss in sarcopenic obese or overweight elderly patients receiving a GLP-1 RA who are at-risk for developing muscle atrophy and muscle weakness."

Evidence of ostarine cross-contamination via sweat in 2 athletes sharing the same neoprene hamstring sleeves. An original situation of drug transfer where the anti-doping rule violation was suspended by the sport authorities. (PubMed, Clin Chim Acta) - "Ostarine was identified in 12 different selected pieces (about 1 g) of the sleeves at concentrations ranging from 3 to 142 pg/g. Sport authorities (USADA) agreed that the most likely source of contamination was the hamstring sleeves, thus confirming the scenario of drug transfer and gave the athlete a no fault."

A screening method for the quantitative determination of selective androgen receptor modulators (SARMs) in capsules by high resolution 19F- and 1H-NMR spectroscopy. (PubMed, Anal Methods) - "A new method for rapid determination of the content of selective androgenic receptor modulators (SARMs) andarine, cardarine, ligandrol, ostarine and S-23 in capsules by 1H- and 19F-high resolution nuclear magnetic resonance spectroscopy was described and validated. The statistical analysis of the results from 19F- and 1H-quantitative NMR showed that both approaches were equally effective, thus expanding the potential use of the methodology to non-fluorinated SARMs. At present, no SARM has been approved for human consumption; however, SARMs are actually used by bodybuilders and recreational athletes, who purchase them even though the risk-benefit ratio of these molecules has not been definitively established."
