Kiadis enrols patients in phase II clinical trial with ATIR for treatment of blood cancer
Amsterdam, The Netherlands | Tuesday, November 19, 2013, 14:00 Hrs  [IST]

Kiadis Pharma BV, a clinical stage biopharmaceutical company developing treatments for blood cancers, has successfully enrolled approximately 10 patients, in phase II clinical trial, of whom the majority have already been transplanted and received ATIR. Its lead programme, ATIR, is a cell-based product designed to enable stem cell transplantations from partially mismatched (haploidentical) family donors for blood cancer patients who do not have a standard of care stem cell donor available.

Topline data from the trial (CR-AIR-007) is expected in the first half of 2014.

The CR-AIR-007 phase II clinical study is an international multi-center study undertaken to corroborate and extend the safety and efficacy results from the previous successful phase I/II dose-escalation study with ATIR. A total of 23 leukaemia patients, including patients with acute myeloid leukaemia (AML), acute lymphoblastic leukaemia (ALL) and myelodysplastic syndrome (MDS) will be enrolled and treated with the optimal dose identified in the phase I/II study. The primary endpoint of the trial is the rate of transplant related mortality six months post a haploidentical stem cell transplant.

Secondary endpoints include overall survival (OS) at one year after transplant as well as relapse rated mortality, non-relapse related mortality, incidence of acute and chronic Graft versus Host Disease (GvHD) and rate of severe infections. Enrollment of patients commenced in Canada and Belgium in April and August 2013, respectively, with the Maisonneuve-Rosemont Hospital in Montreal and Hamilton Health Sciences  participating in Canada and the University Hospitals Leuven, the Institute Jules Bordet in Brussels and the Sint-Jan Academic Hospital in Bruges participating in Belgium.

Manfred Ruediger, PhD, chief executive officer of Kiadis Pharma, commented: “We are delighted that the enrollment into CR-AIR-007 is  progressing according to plan. This demonstrates the demand for ATIR and its significant potential as a lifesaving blood cancer treatment. All patients currently enrolled in the study are alive and doing well and none of them have yet to experience any acute GvHD or serious infections. The majority of patients have been on the study for between two to seven months. We look forward to reporting the topline phase II data in the first half of 2014.” He continues: “Having successfully transferred our manufacturing process for ATIR to our European CMO in Frankfurt am Main, Germany, we now have two manufacturing facilities using our robust process, one for our European sites and one in Montreal for our Canadian sites.”

ATIR is a cell based medicinal product enabling stem cell transplantations using partially mismatched (haploidentical) family members as donors for patients suffering from blood cancer who do not have a standard of care stem cell donor available. A hematopoietic stem cell transplantation (HSCT) is the only potentially curative option for many patients but a matching donor is available for only half of the patients in need. ATIR thus has the potential to address this unmet need and to make a HSCT available for all patients worldwide.
