Actimed Therapeutics secures significant new patent, extending IP coverage of its lead compound for use in key indication


  • Provides extended UK patent coverage relating to lead compound S-pindolol benzoate (ACM-001.1) to 2040
  • International patent application also filed in March 2021

London, UK – 4 May 2022.
Actimed Therapeutics Ltd, a clinical stage company focused on bringing innovation to the treatment of muscle wasting disorders, today announced the grant of a new UK Patent (GB 2593902 B) covering new salts of S-pindolol for use in the treatment or prevention of cachexia with an expiry date in 2040.

An international patent application has also been filed under the Patent Cooperation Treaty (PCT) and was published in October 2021, which seeks to extend patent protection for new S-pindolol salts to all relevant major international markets out to 2041.

S-pindolol benzoate (ACM-001.1) is the leading development candidate of Actimed and is protected by the patent for use in the treatment of cachexia. Actimed plans on initiating Phase 2b/3 clinical studies of S-pindolol benzoate in 2023.

Robin Bhattacherjee, CEO of Actimed commented “We are thrilled to confirm the grant of this new patent which includes protection of our new benzoate salt form of S-pindolol for use in the treatment of cachexia. Strengthening our intellectual property portfolio is fundamental to the commercial value of S-pindolol and supports our plans to develop the first globally approved treatment for cancer cachexia, which affects 50 to 80% of cancer patients worldwide. The granted patent provides enhanced and extended protection of S-pindolol benzoate for use in cachexia until 2040 adding significant value to our lead asset and to the Company as a whole.”

Cachexia is a wasting syndrome that can be difficult to reverse and remains a significant hurdle in the treatment of cancer. It causes sudden loss of weight, appetite and muscle and accounts for up to 20% of all cancer deaths1. In nonclinical models, S-pindolol is an anabolic/catabolic transforming agent2 with a multifunctional effect on a trio of pharmacological targets which could make it an important candidate for development in cancer cachexia.

The potential clinical utility of S-pindolol benzoate as a therapeutic for the treatment of cancer cachexia is supported by data from the ACT-ONE3 Phase II clinical study of S-pindolol (ACM-001) which was a proof of concept exploratory, randomised, double-blind, placebo-controlled study in 87 patients with non-small-cell lung cancer (NSCLC) or colorectal cancer (CRC). The trial demonstrated that S-pindolol was well-tolerated and that patients receiving the highest dose showed a median weight gain of 2.74kg compared to a median 1.09kg weight loss in patients receiving placebo over a 4-month period.

The newly granted patent follows the commencement in December 2021 of a pharmacokinetic and pharmacodynamic (PK/PD) clinical study of S-pindolol benzoate (ACM001.1) in healthy subjects. Data from this study are expected in the first half of 2022 and will be used to further inform the Phase 2b/3 programme.
