Xintela decreases patient number in XSTEM clinical study in difficult-to-heal venous leg ulcers

MARKN.

Xintela has amended the study protocol in the clinical phase I/IIa study with XSTEM on patients with difficult-to-heal venous leg ulcers to complete the study earlier. The number of patients to be enrolled in the study has been reduced from 12 to 6. The primary goal of the study, to investigate safety and tolerability, will be achieved even with the reduced number of patients. XSTEM, which consists of allogeneic (donated) integrin α10β1-selected mesenchymal stem cells, is developed and manufactured by Xintela.

The Phase I/IIa clinical study in patients with difficult-to-heal venous leg ulcers is a placebo-controlled, randomized study. Patients receive one dose of XSTEM or placebo applied to the wound and are assessed weekly for 10 weeks and after 4 months. The primary goal of the study is to show safety and tolerability and, also to investigate the preliminary effect of XSTEM in wound healing.

The number of patients to be enrolled in the study has been reduced from 12 to 6 due to slow recruitment. To date 5 patients have been dosed of which 4 have completed the study. The amended clinical study protocol has received regulatory approval.

“Due to the slow recruitment to this study, we have decided to reduce the number of patients to allow us to complete the study earlier. We have not seen any safety issues in the study, and we will now focus on the next step for XSTEM in wound healing, including burn patients, in collaboration with the Burn Centre in Linköping”, says Camilla Wennersten, Xintela’s Clinical Development Director.
