Pharmacologic Treatments for the Preservation of Lean Body Mass During Weight Loss. (PubMed, J Clin Med) - "There are several mechanisms that govern the loss of lean body mass and, more specifically, the loss of muscle mass; as such, several classes of medications have been explored, targeting different pathways and receptors-including bimagrumab (activin receptor agonist), tesamorelin (growth hormone releasing hormone agonists), and enobosarm (selective androgen receptor modulator). Most of these drugs are in the early phases of research development, but some show great promise. This narrative review attempts to detail the physiology of muscle mass loss when accompanied by weight loss and identify pharmacological targets that can be utilized to minimize it with mechanisms, effects, side effects, and research developmental progress."

Endocrine Therapies and the Bone Metastatic Microenvironment: Dissecting Immune Modulation and Spatial Heterogeneity in Hormone Receptor-Positive Breast Cancer (LCC 2026) - "Here, we investigated how endocrine therapies, including Tamoxifen, Fulvestrant and Enobosarm, affect BM homeostasis using metastatic syngeneic mouse models. Together, these findings illuminate how endocrine therapies remodel the BM niche and highlight the spatial complexity of metastatic BCa. This integrative approach provides a foundation for developing therapeutic strategies that combine endocrine modulation with immune targeting to prevent or treat bone metastases in HR+ BCa."

Manhole Sampling at Gyms and Sports Centers in Denmark: A Pilot Study Using Wastewater Analysis as a Tool for Monitoring the Use of Performance-Enhancing Drugs. (PubMed, Drug Test Anal) - "The study showed the presence of anabolic agents such as oxandrolone, stanozolol, and ostarine in wastewater sampled from the gyms. Wastewater analysis may be used as an easy and cost-effective tool to complement both preventive and control measures, such as information campaigns, surveys, or personal testing. However, not all locations are suitable for manhole sampling, and it is necessary to consider the legal, ethical, and practical aspects before using wastewater analysis to monitor communities or specific populations."

Muscle Loss in Obesity Therapy as a Therapeutic Target: Trial Design and Endpoints for Regulatory Discussions. (PubMed, J Cachexia Sarcopenia Muscle) - "Discussions highlighted the impact of glucagon-like peptide-1 (GLP-1) receptor agonists or GLP-1/glucose-dependent insulinotropic polypeptide (i.e., GLP-1/GIP) agonists on body composition and muscle health; the challenges of distinguishing 'true' skeletal muscle from fat-free tissue; the impact of treatment discontinuation and weight regain; advances in imaging and quantitative assessment of lean body mass; as well as insights from emerging muscle-preserving therapies (e.g., bimagrumab, pemvidutide and enobosarm)...These also involve significant regulatory considerations for future drug development and approval pathways, for instance related to the very large number of individuals that may be considered for these therapeutic approaches as well as from the potential long (or life-long) duration of therapy considered with these drugs. Together, these discussions highlight the growing importance of integrating body composition and functional assessments in future..."

Sarcopenia in Aging: Pathogenesis, Diagnosis, and Emerging Therapeutic Frontiers. (PubMed, Mol Imaging Biol) - "Resistance-based exercise and targeted nutritional support remain first-line, but late-phase trials of myostatin-neutralising antibodies (e.g., LY2495655, bimagrumab) and oral selective androgen-receptor modulators (SARMs; e.g., enobosarm, GSK2881078) now show dose-dependent gains in appendicular lean mass and preliminary functional benefits, signalling that combination regimens integrating lifestyle and drug therapy are imminent. Addressing these challenges requires an interdisciplinary strategy that encompasses molecular, clinical, and public health perspectives to mitigate the personal and societal impacts of sarcopenia. Future efforts must focus on harmonizing diagnostic criteria, refining therapeutic regimens, and leveraging emerging technologies to develop targeted interventions that preserve muscle function and enhance quality of life in the aging population."

Enobosarm in Combination With GLP-1RA is Selective for Fat Loss While Preserving Lean and Function (OBESITY WEEK 2025) - "Phase 2b QUALITY clinical trial is the first human study to show that older patients who are overweight or have obesity and receiving a GLP-1 RA, are at higher risk for accelerated loss of lean mass and associated physical function decline. Oral enobosarm improves body composition by driving a more selective and greater loss of adiposity (fat mass) and preserving both lean mass and physical function in patients receiving semaglutide for chronic weight management."

Pharmacological intervention: Challenges and promising outcomes for fat loss and preservation of lean body mass in the treatment of overweight and type 2 diabetes. (PubMed, Diabetes Obes Metab) - "Activin II receptor inhibition with bimagrumab demonstrated significant preservation and increases in LBM, along with FM reduction, in both preclinical and phase 2 studies in individuals with overweight and T2D. Similar effects were observed for myostatin and activin A inhibitors (trevogrumab, garetosmab), latent myostatin inhibitors (apitegromab, SRK-439), and Selective Androgen Receptor Modulators (enobosarm)...Pharmacological adjunct therapies show potential for improving body composition and physical function during GLP-1 RA-induced weight loss. Preliminary findings are promising, but larger, controlled trials are necessary to confirm efficacy and safety before clinical implementation can be considered."

Effects of Combined Treatment With Selective Androgen and Estrogen Receptor Modulators Ostarine and Raloxifen on Bone Tissue In Ovariectomized Rats. (PubMed, Calcif Tissue Int) - "Here, a combined treatment with a selective estrogen receptor modulator (raloxifene, RAL) and a selective androgen receptor modulator (ostarine, OST) was investigated in ovariectomized rats. Conversely, the combined treatment increased serum phosphorus and luteinizing hormone levels, decreased serum magnesium and calcium, and did not attenuate the organ and uterus weight increase observed after OST, raising safety concerns. These findings highlight the need for cautious evaluation of combination therapies and suggest that there is a need for alternative compounds with improved safety profiles for future osteoporosis treatments."

Rapid detection of illegal selective androgen receptor modulators in unregistered supplements using a combination of selected solid-state analytical methods. (PubMed, ADMET DMPK) - "Unregistered dietary supplements containing anabolic substances, specifically selective androgen receptor modulators (SARMs) such as andarine, ligandrol, ostarine, and testolone became the subject of investigation. Overall, almost half of the analyzed samples of unregistered/illegal sports dietary supplements purchased anonymously online in the Slovak Republic with declared content of at least one SARM did not contain what is declared on the label. Thus the combination of several solid-state analytical techniques without complex sample preparation has proven valuable for rapid identification of APIs in supplements."
