DexTech Medical AB announced that the Phase 1 study investigates the efficacy of OsteoDex in patients with progressive multiple myeloma (MM). The first patient is treated during week 50 at Karolinska University Hospital in Huddinge. The study includes a total of 20 patients and will initially be conducted at three hospitals in Sweden: Karolinska University Hospital Huddinge, Uddevalla Hospital and Sodersjukhuset in Stockholm.

The treatment lasts for a total of 14 weeks with 2 doses per month. Three dose levels are being studied. The Principal Investigator (PI) is Dratarina Uttervall, MD, PhD, Department of Hematology/HERM, Karolinska University HospitalHuddinge.

Analysis of biomarkers takes place at the Central Laboratory, Karolinska University hospital Solna, NKS. Inclusion criteria include adult MM patients with relapsed (pro progressive) refractory disease, who received 1-5 prior lines of therapy. The primary objective is to confirm safety and tolerability and with the secondary objective to determine treatment response.

Biochemical markers are continuously analyzed, and the first assay results are expected in first quarter-24. The study is expected to be completed in fourth quarter, 2024. The work to seek partnerships regarding continued clinical development of OsteoDex - mCRPC towards phase 3 - is ongoing.

The Company's synthesis patent application, filed with the European Patent Office (EPO.org) in October -23, is of great importance for the Company's opportunities for partnership as well as positive results from the Company's MM study. The conditions for the patent application to be granted are good, resulting in market exclusivity until 2044. Without consulting the results from the MM study, Osteodex's positive effect on bone-degrading bone cells and the absence of serious side effects are well documented and will probably be confirmed in the MM study as well.
