5) the Phase I study of MRx0005 or MRx0029 in patients with Parkinson's disease.

4D pharma is working with the administrators to enable an exit from administration as soon as possible and, in the event that the company does exit administration, currently plans to recommence recruitment so long as additional capital funding is secured. Further announcements will be made in due course.

About 4D pharma

4D pharma is a world leader in the development of Live Biotherapeutics, a novel and emerging class of drugs, defined by the FDA as biological products that contain a live organism, such as a bacterium, that is applicable to the prevention, treatment or cure of a disease. 4D pharma has developed a proprietary platform, MicroRx®, that rationally identifies Live Biotherapeutics based on a deep understanding of function and mechanism.

Additional nonclinical-stage programs of LBPs include therapies for central nervous system (CNS) diseases, immune-inflammatory conditions and cancer. 4D pharma has a research collaboration with MSD (a tradename of Merck & Co., Inc., Kenilworth, NJ, USA), to discover and develop Live Biotherapeutics for vaccines.
