NEW YORK, May 30, 2024 – Transcend Therapeutics, a clinical-stage biotechnology company developing rapid-acting treatments for neuropsychiatric diseases, this week presented three posters at the American Society of Clinical Psychopharmacology (ASCP) Annual Meeting in Miami Beach, FL, highlighting the the promise of TSND-201 (methylone).
“Sleep and functional impairments are a significant burden for PTSD patients. These open-label data continue to support the efficacy of methylone as a treatment for PTSD and build upon our previously released data from the open-label portion of the IMPACT-1 study,” said Blake Mandell, Co-founder and Chief Executive Officer of Transcend Therapeutics. “We look forward to continuing our randomized placebo-controlled IMPACT-1 study to better characterize the impact of methylone on improving sleep and functioning.”
Summary of poster presentations:
TSND-201 for the Treatment for PTSD: Functional and Global Improvements from the Open-Label Portion of the IMPACT-1 Study (T36)
- TSND-201 provided meaningful improvements on functioning and global measures of change.
- Overall and across each domain of the Sheehan Disability Scale (SDS), TSND-201 demonstrated rapid and robust improvements in functioning.
- Improvement in functioning was consistent with the clinician-rated global improvements.
TSND-201 for the Treatment for PTSD: Improvement in Sleep-Related Outcomes from the Open-label Portion of the IMPACT-1 Study (W45)
- Participants treated with TSND-201 had a positive impact on sleep.
TSND-201 showed improvements on the sleep-specific items of the Clinician Administered PTSD Scale for PTSD (CAPS-5), in addition to the total severity score. - Similarly, improvements on the sleep item of the Montgomery-Asberg Depression Rating Scale (MADRS) were improved after treatment with TSND-201.
- Improvements in sleep were also consistently improved on the Pittsburgh Sleep Quality Index (PSQI), a general measure of overall sleep.
TSND-201, a rapid-acting treatment for PTSD and other Central Nervous System (CNS) disorders (T89)
- Preclinical evidence for TSND-201’s efficacy in behaviors associated with PTSD, depression and anxiety.
- Parallel clinical results from IMPACT-1 Part A demonstrate TSND-201’s rapid, robust, and long-lasting effects on PTSD, depression and anxiety symptoms.
- Results support development of TSND-201 to treat multiple CNS disorders.
About TSND-201
TSND-201, a rapid-acting neuroplastogen, is a proprietary formulation of methylone developed by Transcend Therapeutics. TSND-201 has well-characterized primary pharmacology, with its primary site of action at the monoamine transporters, and no activity at 5HT-2a (i.e., not hallucinogenic). Transcend is developing TSND-201 as a rapid-acting and durable treatment for PTSD, major depressive disorder (MDD), and anxiety indications.
About IMPACT-1
IMPACT-1 (Investigation of Methylone for Post-Traumatic Stress Disorder) is a 2-part trial evaluating the safety and efficacy of TSND-201 for the treatment of PTSD. Part A is open-label (positive results announced in December 2023); Part B (currently enrolling) is randomized, double-blind, and placebo-controlled. Eligible participants are adults with a confirmed diagnosis of PTSD using the DSM-5 criteria and a CAPS-5 total severity score of ≥35. Study drug is dosed once a week for 4 weeks. During each of the 4 dosing sessions, participants are accompanied by a trained mentor who provides non-directive psychological support. After the 4-week treatment period, participants attend follow-up visits at 1, 2, 3, and 6 weeks following the last dose.
