Single Ascending and Multiple Ascending Dose Trial Demonstrated AJA001 to be Safe and Well-tolerated, with Formulation Optimized for ASD
Presentation at the 63rd Annual Meeting of the American College of Neuropsychopharmacology
LITTLETON, Colo., Dec. 12, 2024 /PRNewswire/ -- DeFloria, a joint venture between Ajna BioSciences and Charlotte's Web (TSX: CWEB, OTCQX: CWBHF), reported positive results from a Phase 1 single ascending and multiple ascending dose trial of AJA001 in development for the treatment of symptoms of autism spectrum disorder (ASD) in a poster presentation at the 63rd Annual Meeting of the American College of Neuropsychopharmacology in Phoenix, Arizona. AJA001 is an orally delivered, multi-cannabinoid botanical drug product (BDP) designed to provide a broad therapeutic effect.

In a poster entitled, "A Single and Multiple Ascending Dose and Food Effect Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of AJA001, a Full-Spectrum Hemp-Derived Botanical Drug for Autism Spectrum Disorder, " Marcel O. Bonn-Miller, Ph.D., Chief Scientific Officer at Charlotte's Web and Board Member at DeFloria, presented the results from the recently completed Phase 1 randomized, double-blind, placebo-controlled trial that evaluated the tolerability and pharmacokinetic (PK) / pharmacodynamic (PD) profile of several dose levels of AJA001 in 70 healthy volunteers ranging from 19 to 55 years.
Results demonstrated that AJA001 was well-tolerated at doses up to 680 mg per day administered as a single dose and up to 660 mg per day administered twice a day. In both the single and multiple ascending dose portions of the trial, AJA001 displayed dose-proportional PK for CBD and THC that matched or exceeded the plasma concentrations of the comparable cannabinoid therapeutics dronabinol, nabiximols, and Epidiolex®. PK data following multiple dose administration of AJA001 showed minimal accumulation of CBD or THC after 7 days.
AJA001's PD effects were shown to be dose-dependent and correlated with peak plasma concentrations of THC and its active metabolite 11-OH-THC after administration of single doses. An analysis of participant responses on the Drug Effects Questionnaire (DEQ) demonstrated that the magnitude and time course of AJA001's subjective drug effects were moderate and transient in nature.
The safety, PK, and PD findings support doses from 100 mg to 660 mg of AJA001 per day for Phase 2 trials in children, adolescents, and adults with ASD. This is equivalent to an upper limit of 395 mg CBD and 15 mg THC per day. The most common treatment emergent adverse events in the AJA001 treated groups were somnolence, anxiety, dizziness, and headache. One serious adverse event was reported by a participant receiving 906.4 mg of AJA001 who reported anxiety that resolved by the next day with no sequalae.

"We are extremely encouraged by these results from our Phase 1 single and multiple ascending dose trial, which demonstrate that AJA001 is well-tolerated across a range of doses and provides a favorable pharmacokinetic profile for both cannabidiol and tetrahydrocannabinol," said Dr. Bonn-Miller. "Importantly, the results from this trial inform the doses to be evaluated in upcoming Phase 2 clinical trials of AJA001 in children, adolescents, and adults with ASD."
"We are excited to present this important data and look forward to initiating two Phase 2 trials of AJA001 in ASD in the second quarter of 2025," said Jared Stanley, CEO of DeFloria. "Despite its prevalence, ASD remains a difficult condition to treat. Moreover, currently available treatments for ASD are not well tolerated, making patient compliance a challenge. DeFloria is committed to supporting the ASD community and developing AJA001 to treat the behavioral symptoms associated with ASD with a drug product that is designed to provide broad therapeutic efficacy."
About ASD
Approximately 1 in 36 children may have ASD (Maenner et al 2023). ASD is characterized by core deficits in (1) social communication, (2) impaired reciprocal social interactions, and (3) restricted, repetitive and stereotyped patterns of behaviors or interests. Irritability, impulsivity, and "temper tantrums" are common symptoms and contribute to high caregiver burden (Lecavalier et al 2006).
About AJA-001
AJA001 Oral Solution is a botanical drug product (BDP) containing full spectrum hemp extract (FSHE) botanical drug substance (BDS) derived from Cannabis sativa L proprietary CW1AS1 hemp cultivar. The primary cannabinoid is cannabidiol (CBD). As an innovative multi-cannabinoid formulation, it may provide broad therapeutic efficacy. Its full-spectrum composition has potential therapeutic applications across various medical conditions due to its varied mechanisms of action.
