Annamycin is the Company’s next-generation anthracycline that has demonstrated a lack of cardiotoxicity in recently conducted human clinical trials for the treatment of AML. Additionally, Annamycin has been shown in animal models to accumulate in the lungs at up to 30-fold the level of doxorubicin. The Company believes that the use of Annamycin may not face the same usage limitations imposed on doxorubicin. Annamycin is currently in development for the treatment of AML and STS lung metastases.

"Based on the preliminary data seen demonstrating clinical benefit for patients receiving a full course of treatment in the 240 mg/m2 cohort and the recommendation from our medical advisors on the dose limiting toxicity criteria, we are pleased to have Ethics Committee approval and the allowance from the URPL to amend the protocol for future patients. This amendment will allow us to continue dose escalation in the Phase 1 portion of the trial and establish the maximum tolerated dose as we work toward the recommended dose for the Phase 2 portion of the study. Our team is committed to advancing this important clinical program forward and to potentially address the limitations with current treatment options for AML patients," commented Walter Klemp, Chairman and CEO of Moleculin.

The Phase 1/2 AML trial in Poland remains ongoing and is currently dosing patients at 240 mg/m2. Under the previous protocol transient elevated liver enzymes (AST and ALT) observed in two patients were considered a dose limiting toxicity (DLT), which investigators believe would inappropriately limit the potential for continued dose escalation. The amendment to the Annamycin clinical trial protocol allows for a change in the DLT criteria as it relates to transient grade 3 elevations and allows dosing of three additional patients in the 240 mg/m2 cohort. If no DLT (as defined by the new criteria) is experienced with these next three patients, the Company plans to escalate dosing in new cohorts by 30 mg/m2 instead of the 60 mg/m2 previously planned, and with a de-escalation of 15 mg/m2 at the DLT dose if future patients experience a DLT.

The results from the Phase 1 portion of the Company’s U.S. Phase 1/2 clinical trial of Annamycin for the treatment of AML met its primary endpoint and demonstrated a clean safety profile with no evidence of cardiotoxicity when delivered to patients at or below the lifetime maximum anthracycline dose established by the FDA. To date, an independent expert assessment of the absence of cardiotoxicity in the first 19 patients treated with Annamycin in both the Company’s U.S. and European Phase 1 clinical trials in which an independent expert concluded that he "does not see evidence of cardiotoxicity."

Moleculin Biotech expects to continue reporting cohort topline results from the ongoing Phase 1/2 study for treatment of AML and to report the study’s topline results in the second half of 2022. Annamycin has been granted Fast Track Status and Orphan Drug Designation from the U.S. Food and Drug Administration for the treatment of AML.

Zydis technology creates a freeze-dried tablet that disperses almost instantly in the mouth without water, and is recognized as one of the world’s best-performing ODTs. In the feasibility study, scientists at Catalent’s facility in Swindon, U.K., will focus on establishing proof of concept and prototype development of a Zydis formulation of a highly purified, naturally derived CBD. JOS Pharmaceuticals extracts CBD from certified hemp and is developing its se•d8 prescription CBD wafer for awake sedation anesthesia administered for cataract surgery, as well as anxiolysis during magnetic resonance imaging (MRI) procedures.

"Our clinical trial product is specifically designed to provide rapid and reliable relaxation for the patient, while still allowing for awake cooperation during the procedure. It would be paradigm changing to replace the DEA controlled drugs used currently as premedication with a safe and effective botanical," said Stephen D. Ochs, M.D., Chief Executive Officer of JOS Pharmaceuticals.

"Zydis is an ideal dose form for the delivery of drugs, as it offers an easy and convenient route of administration for patients that can also assist in the rapid onset of effects," said Jonathan Arnold, President of Oral and Specialty Delivery at Catalent. "CBD derived from hemp is a rapidly evolving market, and our team in Swindon is looking forward to applying its experience and expertise in product development to this licensed program."

Catalent’s 250,000-square foot site in Swindon, U.K. houses the company’s Zydis development and manufacturing operation, which produces more than one billion ODTs annually.
