| Item 8.01 | Other Events. |
On July 30, 2024, the Company announced clinical data from the first dose cohort (5 mg/kg) of PGN-EDO51, its lead investigational candidate for patients with DMD whose mutations are amenable to an exon 51-skipping approach.
CONNECT1 Results for the 5 mg/kg Starting Dose Cohort (n=3)
Exon 51 Skipping and Dystrophin Production Data
| • | Exon 51 Skipping: PGN-EDO51 produced mean exon skipping in biceps tissue of 2.15% at week 13 compared to baseline. |
| • | Dystrophin Production |
| • | PGN-EDO51 achieved a mean muscle-adjusted dystrophin level of 1.49% of normal and a 0.70% change from baseline after 4 doses, measured at week 13. |
| • | PGN-EDO51 achieved a mean absolute dystrophin level of 0.61% of normal and a 0.26% change from baseline after 4 doses, measured at week 13 by Western blot analysis. |
Safety and Tolerability Data
The 5 mg/kg dose of PGN-EDO51 was well tolerated by all study cohort participants through week 13. There were no discontinuations, dose interruptions or dose reductions.
| • | The one related treatment-emergent adverse event was mild and resolved. |
| • | There was no sustained elevation in kidney biomarkers. There were no cases of hypomagnesemia or hypokalemia. There were also no changes in electrolytes or hepatic function and no cases of anemia or thrombocytopenia. |
| • | All three patients in this cohort are continuing to be dosed with PGN-EDO51 at 5 mg/kg in the long-term extension (LTE) phase of the clinical trial. PGN-EDO51 continues to be well tolerated during the LTE as of July 29, 2024. |
The Company plans to present additional results from the 5 mg/kg cohort at a medical meeting later in the year.
Update on PGN-EDO51 10 mg/kg Cohort
As of July 29, 2024, two participants have received a total of four doses at 10 mg/kg in the ongoing CONNECT1 study. To date, PGN-EDO51 has been generally well tolerated at this dose level and the Company expects to report initial results from the 10 mg/kg cohort in early 2025.
Update on CONNECT2-EDO51 Clinical Trial
Based on the data from CONNECT1, including PGN-EDO51’s emerging safety profile to date, the Company is working to optimize the design of the CONNECT2 Phase 2 double-blind, placebo-controlled 25-week multinational trial. The CONNECT2 clinical trial is open in the United Kingdom. The Company continues to engage with regulators in the European Union and expects to open the clinical trial in the United States by year-end.
