Cyclo Therapeutics Announces Positive Efficacy Data from Extension Protocol with Trappsol® Cyclo™ in Patients with Niemann-Pick Disease Type C
Cyclo Therapeutics (NasdaqCM:CYTH, CYTHW) announced initial data from its open-label study of Trappsol® Cyclo™ for Niemann-Pick Disease Type C (NPC). All eight patients in the study demonstrated disease stability or improvement in NPC Severity Scores over 10 months. Notably, patients receiving 1500 mg/kg showed stable scores, while those at 2500 mg/kg improved significantly. The safety profile was favorable, with only mild adverse events reported. Cyclo Therapeutics has FDA authorization to begin a Phase 3 trial, expected to enroll patients in early 2021, enhancing the company's position in the neurodegenerative disease market.
- Eight patients in the study showed disease stability or improvement in NPC Severity Scores.
- Patients receiving Trappsol® Cyclo™ at 1500 mg/kg had stable scores; two patients improved.
- Patients at 2500 mg/kg showed significant improvements in NPC Severity Scores.
- Favorable safety profile with only mild adverse events reported.
- FDA authorization obtained for Phase 3 trial commencing early 2021.
- None.
Cyclo Therapeutics, Inc. (NasdaqCM:CYTH) (NasdaqCM:CYTHW), a clinical stage biotechnology company developing a cyclodextrin platform for the treatment of neurodegenerative diseases, including its lead candidate Trappsol® Cyclo™ for the treatment of Niemann-Pick Disease Type C (NPC), today announced initial data from its “Open-Label Study of Long-Term Safety and Efficacy of Intravenous Trappsol® Cyclo™ (HPBCD) in Niemann-Pick Disease Type C,” NCT03893071. Eight patients living in the US who completed the Phase I trial (NCT02939547) were eligible for the extension program. All eight enrolled.
The first patient was dosed in the Open-Label extension study in May 2019 and the last patient enrolled was in February 2020. The initial efficacy results presented below have a data cut-off of September 2020.
All patients included in this analysis demonstrated disease stability or improvement as measured by the 17-domain NPC Severity Score scale (NPC-SS, Yanjinin et al, 2010). The NPC-SS measures primarily neurologic features of the disease, including ambulation, fine motor skills, ability to speak and swallow, and cognition. Without intervention, over the course of one year, NPC patients would be expected to worsen by one to two points using this scale.
During this Open-Label Study, patients receive intravenous infusions of Trappsol® Cyclo™ in their homes under the care of healthcare professionals every two weeks, with regular assessments for NPC-SS at UCSF Benioff Children’s Hospital Oakland under the care of Dr. Caroline Hastings and Dr. Benny Liu, Co-Principal Investigators.
Of the patients who received Trappsol® Cyclo ™ at the 1500 mg/kg body weight dose level, four patients remained stable in terms of their NPC-SS and two patients improved:
Patient 1 had a baseline NPC-SS of 24; and the same score 10 months later.
Patient 2 had a baseline NPC-SS of 18, with the same score 4 months later and again 6 months after the second assessment.
Patient 3 had a baseline NPC-SS of 11 and the same score 7 months later.
Patient 4 had a baseline NPC-SS of 12 and the same score 6 months later.
Patient 5 had a baseline NPC-SS of 16, a score of 15 five months later (improvement of 1 point), and a score of 13 eight months later (representing improvement by total 3 points).
Patient 6 had a baseline NPC-SS of 12 and a score of 10 eight months later (an improvement of 2 points).
Of the patients in the 2500 mg/kg dose group, both improved overall:
Patient 7 had a baseline NPC-SS of 18, followed by a score of 20 four months later (a worsening of 2 points) and a score of 15 six months later (a total improvement of 3 points compared to baseline during the 10-month assessment period).
And, Patient 8 had a baseline NPC-SS of 12 and a score of 8 five months later (an improvement of 4 points).
“These preliminary data provide additional signals of efficacy for our drug as a treatment for NPC, a progressive and debilitating disease often leading to premature death. The fact that patients either stabilized or improved during periods up to one year is consistent with data emerging from our Phase I/II in Europe and Israel,” said Cyclo Therapeutics CEO and Director, N. Scott Fine. “These extension protocol data provide additional compelling support for the efficacy of our drug in this patient population, and as we launch our pivotal Phase 3 trial in early 2021.”
The safety profile was favorable with 16 Adverse Events (AEs) in total between May 2019 and September 2020, all mild (Grade 1 and 2) and none related to the study drug, per the treating physician.
“NPC is a progressive, devastating disorder without approved therapies in the United States. The overall safety profile of Trappsol® Cyclo™ is reassuring in that the drug is well tolerated, with adverse events in the mild and moderate range of severity. In addition, the clinical trajectory of the participants suggests stabilization while on therapy. These results offer the exciting promise of an effect on the progression of symptoms in NPC, a notable breakthrough for this condition,” said Loren Pena, MD, PhD, Associate Professor, Department of Pediatrics, University of Cincinnati College of Medicine and Attending Physician, Division of Human Genetics, Cincinnati Children’s Hospital, who is not associated with the study.
Cyclo Therapeutics has authorization from FDA to begin enrollment in its phase 3 trial and plans to enroll the first patient early in 2021.
