9 Loss of Lean Muscle Is Significant with GLP - 1 RA Therapies Lean muscle is essential to healthy metabolic function & body composition Situation • Significant challenges with current weight loss strategies (dietary/behavioral, pharmacological, surgical), including tolerability, lack of durability and significant muscle loss 1,2,3 • Recently approved GLP - 1 receptor agonists (GLP - 1 RAs) are highly effective in weight loss & experiencing rapid uptake • However, 25% - 40% of total body weight loss mediated by GLP - 1 RA therapy may be attributed to loss of lean muscle mass 2,3 • Preserving lean muscle mass is important to promote long - term metabolic benefits, sustainable weight management and health outcomes 4,5,6,7 Significant proportion of weight loss due to loss of lean muscle mass 1 Muller TD, et al Anti - obesity drug discovery: advances and challenges.

11 Recent KOL Interviews: Select Physicians See Value and Benefit in Muscle Maintenance During Weight Loss » Some key opinion leaders (KOLs) see a lack of standard of care (SOC) in obesity which leads to significant unmet need in large patient population » KOLs see the potential for additional benefit to patients as sustained results stem from exercise, proper diet and treatment » Combination therapy with other weight loss drugs (GLP - 1 RA) may have a synergistic effect on weight loss and benefit overall patient health » Patients may experience prolonged weight - loss and sustained results through the addition of muscle - targeted therapy Key Opportunities “There isn’t a set SOC right now for obesity and there clearly needs to be something out there that is standard and addresses the entire scope of the disease. If a company could address both weight loss and muscle maintenance, I think this could improve SOC significantly.” - KOL , PCP “I do see the importance of muscle mass, and this is something that if I could add to my patient’s program, I would in a heartbeat and really think it would make an impact. I have a lot of patients that would benefit from something like this.” - KOL , Endocrinologist Source : Clarion 2022 Analysis, Clarion KOL interviews
12 We believe Therapeutic Strategy for Safe, Durable Weight Loss Could Include a Highly Selective Antimyostatin to Retain Lean Muscle Opportunity • Inhibition of myostatin has demonstrated important physical (increased muscle mass) and beneficial metabolic effects (insulin sensitivity, basal metabolic rate, reduction in fat mass) in preclinical models 1 • Strong evidence has indicated upstream targeting of structurally differentiated pro - and latent myostatin leads to exquisite selectivity and avoids undesirable off - target effects 2 - 4 • Inhibition of myostatin in combination with GLP - 1 RA - driven weight loss may lead to retention of lean muscle mass and combat the counter - regulatory metabolic effects of weight loss 1 Yang M et al.

13 Scholar Rock Antibodies Selectively Inhibit Activation of Myostatin Selective Targeting of Proforms of Myostatin SRRK antibodies do not bind to mature myostatin or any form of GDF11, Activin A, or other TGF - β family members Selectivity is critical to avoid safety concerns ▪ Mature myostatin and mature GDF11 have 90% sequence conservation ▪ Most prior myostatin approaches bind/inhibit both myostatin and GDF11 ▪ GDF11 loss leads to embryonic lethality, skeletal and kidney formation defects 1 ▪ GDF11 signaling inhibition may have negative impacts on bone 2 Broad inhibition of ActRIIb signaling may be problematic ▪ ActRIIB knockout animals die shortly after birth with developmental defects in respiratory and cardiac organs 3 ▪ Activins are critical in reproductive biology and inhibition was shown to reduce FSH levels in women 4 13 1.McPherron AC et al Nat Genet 1999, 22(3):260 - 264.; 2.
