Biodexa Pharmaceuticals PLC
(“Biodexa” or the “Company”)
Results of Annual General Meeting
Biodexa Pharmaceuticals PLC (NASDAQ: BDRX), a clinical stage
biopharmaceutical company developing a pipeline of innovative products for the treatment of diseases with unmet medical needs, announces
that at its Annual General Meeting held yesterday, all resolutions put to the Company’s shareholders were duly passed.
The
full text of, inter alia, the resolutions proposed and passed at the Annual General Meeting can be found in the Notice of the Annual
General Meeting on the Company's website at https://biodexapharma.com/investors/corporate-governance//#agms.
About Biodexa Pharmaceuticals PLC
Biodexa Pharmaceuticals PLC (listed on NASDAQ: BDRX) is a clinical
stage biopharmaceutical company developing a pipeline of innovative products for the treatment of diseases with unmet medical needs. The
Company’s lead development programs include eRapa, under development for Familial Adenomatous Polyposis and Non Muscle Invasive
Bladder Cancer: tolimidone, under development as a for the treatment of type 1 diabetes; and MTX110, which is being studied in aggressive
rare/orphan brain cancer indications.
eRapa is a proprietary oral tablet formulation of rapamycin,
also known as sirolimus. Rapamycin is an mTOR (mammalian Target Of Rapamycin) inhibitor. mTOR has been shown
to have a significant role in the signalling pathway that regulates cellular metabolism, growth and proliferation and is activated during
tumorgenesis.
Tolimidone is an orally delivered, potent and selective inhibitor
of Lyn kinase. Lyn is a member of the Src family of protein tyrosine kinases, which is mainly expressed in hematopoietic cells, in neural
tissues, liver, and adipose tissue. Tolimidone demonstrates glycemic control via insulin sensitization in animal models of diabetes and
has the potential to become a first in class blood glucose modulating agent.
MTX110 is a solubilised formulation of the histone deacetylase
(HDAC) inhibitor, panobinostat. This proprietary formulation enables delivery of the product via convection-enhanced delivery (CED) at
chemotherapeutic doses directly to the site of the tumor, by-passing the blood-brain barrier and potentially avoiding systemic
toxicity.
Biodexa is supported by three proprietary drug delivery technologies
focused on improving the bio-delivery and bio-distribution of medicines. Biodexa’s headquarters and R&D facility is in Cardiff,
UK. For more information visit www.biodexapharma.com.
