Collaboration will support Phase III clinical trial of cell therapy product ATIR101™ for blood cancers

MINNEAPOLIS & AMSTERDAM, May 22, 2019 — Be The Match BioTherapies®, an organization offering solutions for companies developing and commercializing cell and gene therapies, and Kiadis Pharma N.V. (“Kiadis”) (Euronext Amsterdam and Brussels: KDS), a clinical stage biopharmaceutical company, today announced a strategic collaboration to support clinical evaluation of an innovative cell therapy product with potential to make haploidentical hematopoietic stem cell transplantations (HSCT) safer and more effective for patients.

Under the terms of the collaboration agreement, Be The Match BioTherapies will provide logistical and technological solutions to support Kiadis’ Phase III clinical trial for ATIR101, an adjunctive immunotherapeutic designed to address key risks and limitations of HSCT in the treatment of blood cancers.

Kiadis’ multinational Phase III clinical trial is evaluating the safety and efficacy of ATIR101 as an adjunctive treatment to HSCT from a half-matched (haploidentical) family donor compared to post-transplant cyclophosphamide (PTCy or “Baltimore” protocol) in adult patients with blood cancers. The Phase III study is currently enrolling patients in the EU, Canada, Israel and the U.S.

The collaboration will leverage Be The Match BioTherapies’ industry-leading expertise in cell delivery logistics and supply chain case management, including the company’s MatchSource® end-to-end supply chain management software, to manage the transport and processing of cellular products for use at Kiadis’ clinical trial sites in the U.S. and Canada.

“Kiadis’ quest to provide better treatment outcomes for patients receiving stem cell transplants is one we deeply share, given the foundational role that our parent company, the National Marrow Donor Program®/Be The Match®, has played in improving stem cell transplantation for more than three decades,” said Chris McClain, Vice President of Sales and New Business Development, Be The Match BioTherapies. “We look forward to utilizing our cell therapy expertise to advance Kiadis’ important work.”

“We’re pleased to partner with Be The Match BioTherapies to progress our clinical investigation of ATIR101 and to expedite its availability to patients,” said Andrew Sandler, Chief Medical Officer of Kiadis Pharma. “We believe this therapeutic approach could allow family members to serve as stem cell donors for those patients who would otherwise not find a matching donor in time, ultimately saving lives.”

About ATIR101

ATIR101TM is an investigational allodepleted T-cell immunotherapy product candidate, which is designed to be given after a haploidentical (genetically half-matched) hematopoietic stem cell transplantation (HSCT).

Administered as an adjunctive immunotherapeutic on top of HSCT, ATIR101 provides a single dose donor lymphocyte infusion (DLI) with functional, mature immune cells from a haploidentical family member. The T-cells in ATIR101 will help fight infections and remaining tumor cells, until the immune system has fully re-grown from stem cells in the transplanted graft.

In ATIR101, T-cells that would cause GVHD are depleted from the donor lymphocytes, using our photodepletion technology. At the same time, ATIR101 contains potential cancer-killing T-cells from the donor that could eliminate residual cancer cells and help prevent relapse of the disease.
