Restraint/Challenge

Drug Resistance and High Development Costs

• Challenges surrounding acquired resistance to SERDs and potential adverse effects pose a significant hurdle to broader market penetration. As tumors evolve, some patients may develop resistance, limiting long-term efficacy and requiring alternative treatment strategies
  • For instance, high-profile reports of endocrine therapy resistance in advanced breast cancer have made clinicians cautious about long-term monotherapy with SERDs
• Addressing these resistance concerns through combination therapies, novel drug candidates, and optimized dosing regimens is crucial for maximizing therapeutic outcomes. Companies such as AstraZeneca and Eli Lilly emphasize ongoing R&D and clinical studies to overcome these limitations. In addition, the high cost of drug development, including clinical trials and regulatory approvals, can be a barrier for new entrants and emerging SERD therapies, particularly in cost-sensitive healthcare markets
• While prices for oral SERDs are gradually stabilizing, the perceived premium for novel targeted therapies can still hinder widespread adoption, especially in regions with limited reimbursement coverage
• Overcoming these challenges through innovative drug design, combination strategies, patient support programs, and global access initiatives will be vital for sustained growth of the Selective Estrogen Receptor Degraders (SERD) Therapeutics market

What are the Recent Developments in Global Selective Estrogen Receptor Degraders (SERD) Therapeutics Market?

• In November 2025, Roche announced that in the Phase III lidERA trial, its oral SERD giredestrant (GDC‑9545) demonstrated a statistically significant and clinically meaningful improvement in invasive disease‑free survival (iDFS) versus standard-of-care endocrine therapy in early‑stage ER‑positive, HER2‑negative breast cancer
• In June 2025, AstraZeneca announced positive interim results from the Phase III SERENA-6 trial: switching to camizestrant + a CDK4/6 inhibitor (versus continuing standard aromatase inhibitor + CDK4/6) in first-line treatment reduced risk of progression or death by 56%. The median PFS for the camizestrant arm was 16.0 months vs 9.2 months in the standard-of-care arm
• In May 2025, Olema Oncology announced their selection of 90 mg once-daily dose for palazestrant (OP-1250) in the pivotal Phase III OPERA-01 monotherapy trial. This dosing decision was made in agreement with the FDA, signaling regulatory alignment and increasing confidence in the chosen regimen
• In May 2023, Menarini (Stemline) presented a new subgroup analysis from the EMERALD trial at ASCO 2023, showing that elacestrant may benefit patients without detectable ESR1 mutations who progressed rapidly on a prior CDK4/6 inhibitor. In this analysis, patients who had disease progression within 6 months of prior CDK4/6 inhibitor therapy showed a median PFS of 5.32 months on elacestrant vs 1.87 months on standard-of-care
• In January 2023, the U.S. FDA approved elacestrant (Orserdu, RAD 1901) for ER positive, HER2 negative, ESR1 mutated advanced or metastatic breast cancer in patients whose disease progressed after at least one line of endocrine therapy. This was a landmark approval because elacestrant is an oral SERD, making it more convenient than older injectable endocrine therapies
