Muscle Loss & Sarcopenia: Emerging Drug Modalities, Bio-Target Innovation, Competitive Pipeline & Global Market Outlook, 2025-2040

Executive Summary / Description

Muscle loss - spanning sarcopenia, cachexia, disuse atrophy, and GLP-1-associated muscle decline - is emerging as a priority therapeutic frontier driven by global demographic and metabolic shifts.

By 2035, over 1.5 billion people will be aged >60, and >250 million patients treated with GLP-1 agonists will be at risk of drug-induced sarcopenia, accelerating clinical urgency.

Historically managed through exercise, protein nutrition, and physical therapy, the field is now entering a biological medicine era characterized by:

• Myostatin/activin-A pathway blockade
• Selective androgen receptor modulators (SARMs)
• Mitochondrial biogenesis activators
• Anabolic peptides & myokine-based therapies
• Neuromuscular trophic modulation
• Adipomyokine axis reprogramming
• AI-driven digital muscle biomarkers & precision movement diagnostics

Drivers transforming this market: Macro Trend and its Implications

• Aging population: Exponential rise in sarcopenia burden
• GLP-1 expansion: Muscle depletion & metabolic fragility flags
• Cancer care & cachexia: Oncology supportive-care expansion
• Longevity medicine: Muscle seen as core biological organ system
• Sports performance -> medical translation: Advanced protein synthesis biology

Muscle is increasingly recognized not as a mechanical tissue but as a metabolic, endocrine, mitochondrial, and immunologic organ, producing myokines (Irisin, IL-15, Myostatin, FGF-21, GDF11) with systemic signaling effects.

Muscle mass = metabolic reserve + cognitive aging predictor + survival biomarker.
