Press Release, Lund April 21, 2021

Hamlet Pharma is proud to announce that the report of the phase I/II bladder cancer trial has been accepted for publication in Nature Communications; a leading international journal.

The paper is entitled “Bladder cancer therapy using a conformationally fluid tumoricidal peptide complex” and has been accepted for publication in Nature Communications. The Nature journals are extremely competitive and only accept innovative science of highest quality and with significant interest for a discerning audience. The journals are widely read, with a high impact.

The paper analyses the structure of the Alpha1H complex, characterizes its tumor killing effects and describes the successful clinical trial of Alpha1H in patients with bladder cancer. A detailed analysis of primary and secondary end points is provided and differences between the Alpha1H treated patients and the placebo group are described for several crucial efficacy variables. Alpha1H triggered significant shedding of tumor cells in patients, who received the treatment (p< 0.0001 compared to the placebo group) and reduced the tumor size (p<0.04), illustrating its potent effects.

The treatment is also shown to be safe, as no drug-related side effects were observed. The publication offers interested readers a detailed understanding of the molecular properties and promising clinical effects, inspiring further development of Alpha 1H as a new potential drug for patients with bladder cancer.

Publishing in Nature journals is an important quality stamp and an excellent way to spread the news of our clinical advances” says Catharina Svanborg, founder, CMO and chairman of the board of Hamlet Pharma Ltd.

This is a very important milestone, inspriring us to continue the clinical development of Alpha1H with full speed” says Mats Persson, CEO of Hamlet Pharma Ltd.

About HAMLET Pharma
HAMLET Pharma, listed on Spotlight, develops drugs based on the unique tumoricidal protein-lipid complex, HAMLET, formed by two natural and harmless molecules found in breast milk. Development focuses primarily on drugs, for the treatment and prevention of cancer. HAMLET kills tumour cells and has proven safe in proof-of-concept studies in animal models. Alpha1H is the synthetic variant of HAMLET, which has enabled development of the agent for clinical trials. Alpha1H kills different types of tumour cells and has demonstrated therapeutic effects on bladder cancer in animal models. Hamlet Pharma has one ongoing Phase I/II clinical trial with Alpha1H in patients with bladder cancer, a costly form of cancer that is difficult to treat, and intends to expand its activities into other types of cancer. The first results from the ongoing clinical Phase I/II study shows no side effects of Alpha1H, indicating that the treatment is safe and well tolerated. Alpha1H also demonstrated clinical efficacy compared with patients who received placebo. In addition, Hamlet Pharma develops BAMLET, which is a molecular complex formed by bovine α-lactalbumin and oleic acid. Data from animal models suggest that local BAMLET treatment may be effective against colon cancer.

The project is coordinated by Prof. Catharina Svanborg and CEO Mats Persson of Hamlet Pharma. This project is funded from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 954360.
