AMXT 1501 Updates

As of November 2022, Aminex Therapeutics completed enrollment of patients into the Expansion part of their Phase 1 AMXT1501-101A clinical study, consisting of AMXT 1501 in combination with DFMO in oral capsule formulation. Aminex Therapeutics has opened a new formulation study as of August 2022, available for patients with DIPG, DMG and other solid tumors ages 12 years and older and that weigh more than 40 kg (88 lbs).

This Phase 1B/2A trial will evaluate AMXT 1501 (oral capsule) in combination with DFMO in an intravenous formulation in adult patients with advanced solid tumor cancers, and both adolescent and adult patients with DIPG/DMG (ages 12 and above). The Phase 1B primary objectives are to establish both safety and the recommended Phase 2 dose for Aminex’s dual drug treatment. The Phase 2A goal is to evaluate the dual drug treatment in an array of cancers to assist in determining the cancer selection(s) for future Phase 2 studies. This trial utilizes a small ambulatory pump to continuously administer DFMO to patients. The pump and IV bag are contained in a small lightweight pouch that is carried by patients as they go about their daily activities. IV bags are changed weekly.

Future cohorts will increase the dose of IV DFMO while holding the oral AMXT-1501 dose steady.

Aminex is also collaborating and discussing details with several non-profit organizations, including The Cure Starts Now, who have expressed interest in supporting pediatric trials, under Aminex’s current Investigational New Drug (IND) application with the FDA. These trials will include patients diagnosed with DMG/DIPG and neuroblastoma. We envision these trials starting later in 2023.
