1 min read

Chiasma Inc (NASDAQ: CHMA) has announced new data from the MPOWERED Phase 3 trial of Mycapssa as the first oral therapy to treat acromegaly.

  • Chiasma presented the data at the Endocrine Society’s annual meeting.
  • The data from MPOWERED showed that Mycapssa improved clinical symptoms and other patient-reported outcomes compared to long-acting injectable somatostatin receptor ligands (iSRLs) in patients with acromegaly.
  • Additionally, Mycapssa met the pre-specified non-inferiority margin compared to long-acting iSRLs in the maintenance of biochemical response.
  • Data showed that Mycapssa demonstrated non-inferiority to iSRLs in maintaining a biochemical response; 91% of the Mycapssa patients maintained insulin-like growth factor 1 (IGF-1) response.
  • The overall mean symptom score decreased from 4.5 to 3.5; the mean change from baseline was statistically significant and clinically meaningful.
  • Overall, 80.4% of the randomized patients maintained or improved their symptoms score during the run-in phase compared to baseline.
  • At the end of the RCT phase, 15% of patients reported breakthrough acromegaly symptoms in the octreotide capsules group and 31% of patients in the iSRLs group.
  • Adverse event incidence and nature were similar to the known octreotide safety profile and acromegaly disease burden.
  • Price Action: CHMA shares are trading 3.8% higher at $3.54 in the premarket on the last check Monday.
