Satellos Announces First Participant with Duchenne Muscular Dystrophy Dosed in the Phase 1b Clinical Trial of SAT-3247

In This Article:

- Marks successful completion of full enrollment of SAD cohorts and the first two MAD cohorts in the healthy volunteer study

- Up to 10 adult participants with genetically confirmed Duchenne Muscular Dystrophy ("DMD") to be enrolled in the now ongoing Phase 1b trial in DMD patients

- Phase 1 data to be presented at major medical conference in Q1 2025

TORONTO, December 11, 2024--(BUSINESS WIRE)--Satellos Bioscience Inc. (TSX: MSCL, OTCQB: MSCLF) ("Satellos" or the "Company"), a public biotech company developing new small molecule therapeutic approaches to improve the treatment of muscle diseases and disorders, announced today that the first participant with Duchenne muscular dystrophy ("DMD") has been dosed in the Phase 1b safety and pharmacokinetics ("PK") trial in DMD patients.

"The dosing of our first DMD participant is a major milestone in evaluating SAT-3247’s potential benefit for DMD patients," said Frank Gleeson, Satellos Co-founder and CEO. "We are very pleased to have safely completed the full enrollment and dosing of all five cohorts in the single ascending dose ("SAD") study and the first two multiple ascending dose ("MAD") cohorts. This reinforces our view that SAT-3247 has potential to be a safe and tolerable, once-daily, oral treatment option for DMD patients. We look forward to continuing to advance SAT-3247 as a potential disease modifying therapy for degenerative muscle conditions."

Satellos expects to enroll up to 10 adult participants with genetically confirmed DMD in a 28-day, open-label, single dose cohort to assess safety and PK properties in patients and explore potential pharmacodynamic markers.

Clinical data results to date:

Healthy volunteers dosed with SAT-3247 in the SAD cohorts of the study and the first cohort of the MAD did not experience any adverse side effects and the drug was well tolerated. Safety findings include:

  • No drug-related adverse events reported

  • No abnormal findings on clinical labs

  • No abnormal findings on vitals

  • No abnormal findings on ECG

  • No abnormal findings on physical exams

In addition, the PK profile of SAT-3247 in healthy volunteers translated effectively from pre-clinical models into human subjects.

About the Phase 1 DMD Trial

The Phase 1 clinical trial is comprised of two components. In the first component, 72 healthy adult volunteers are being enrolled in a blinded, randomized, placebo-controlled study to assess the safety and pharmacokinetic properties of SAT-3247. Volunteers are randomized across five SAD cohorts, four MAD cohorts, and one food effect dose cohort. The second component, the Phase 1b portion of the trial, is currently ongoing and up to 10 adult participants with genetically confirmed DMD will be enrolled in a 28-day, open-label, single dose cohort to assess safety and pharmacokinetic properties in patients and explore potential pharmacodynamic markers.
