Item 8.01 Other Events.
On July 9, 2024, the Company announced updated interim data from its ongoing clinical trials of AMT-130, a one-time administered investigational gene therapy for the treatment of Huntington’s disease. The interim data include follow-up data from patients enrolled in the Company’s two ongoing multi-center, dose-escalating Phase I/II clinical trials in the U.S. and Europe as of a March 31, 2024 cut-off date.
In the U.S. trial, 26 patients with early manifest Huntington’s disease were randomized to treatment (6 low-dose patients, 10 high-dose patients) or an imitation (sham) surgical procedure (10 patients). The U.S. trial consists of a blinded 12-month core patient study period followed by an unblinded long-term follow-up period of five years. An additional four control patients crossed over to treatment. In the European trial, 13 patients with early manifest Huntington’s disease were enrolled and treated with AMT-130 (6 low-dose patients, 7 high-dose patients). A third cohort of up to 12 patients is currently being enrolled between U.S. and European sites to explore both doses of AMT-130 in combination with immunosuppression.
The combined U.S. and European interim data discussed in Item 8.01 of this Current Report on Form 8-K are subject to a March 31, 2024 cut-off date and do not include outcome or biomarker data from the control patients who have crossed over to treatment with AMT-130 following the 12-month core study period. Across both studies, 24-month follow-up data from a total of 21 patients (12 low dose patients, 9 high-dose patients) were available for analysis as of the cut-off date.
The Company conducted a post-hoc statistical analysis of clinical outcomes for the 21 treated patients at 24 months compared to a propensity-weighted external control cohort developed in collaboration with the Cure Huntington’s Disease Initiative (CHDI) using data from the TRACK-HD, TRACK-ON and PREDICT-HD natural history studies. The external control cohort includes 154 patients that met the Phase I/II clinical trial eligibility criteria and whose data contributions were statistically weighted using propensity scoring to closely match the baseline characteristics of patients treated with AMT-130. Disease-related outcomes for these cohorts were then compared after 24 months of follow-up and are summarized below. Measures of statistical significance in this analysis are based on nominal p values and are unadjusted.
| ● | A statistically significant, dose-dependent, slowing in disease progression measured by composite Unified Huntington’s Disease Rating Scale (cUHDRS) was observed through 24 months in patients receiving the high dose of AMT-130. |
| o | At 24 months, the mean change in cUHDRS for patients receiving the high-dose of AMT-130 was -0.2 compared to -1.0 for patients in the propensity score-weighted external control, representing an 80% slowing of disease progression (p=0.007). |
