Kiadis Pharma N.V. , a clinical stage biopharmaceutical company developing innovative T-cell immunotherapy treatments for blood cancers and inherited blood disorders announces that it has obtained regulatory approval from the national authority in Belgium.
The FAGG, the Federal Agency for Medicines and Health Products) to start its randomized, controlled, transatlantic Phase III clinical trial with ATIR101โข for acute leukemia (CR-AIR-009) in Belgium. In addition, the Company has received regulatory approval from the national authority in Germany (the PEI, the Paul-Ehrlich-Institute) to start its Phase I/II clinical trial with ATIR201โข for thalassemia (CR-BD-001).
This follows after the previous Company announcement in February 2017 that the Phase III trial with ATIR101โข has been initiated following regulatory approval from the national authority in Canada, and from the previous Company announcement at the end of 2016 that it had initiated the Phase I/II trial with ATIR201โข after having obtained regulatory approval from the national authority in the United Kingdom.
About ATIR101โข
For patients suffering from blood cancers, an allogeneic hematopoietic stem cell transplantation (HSCT) is generally regarded as the most effective curative approach. During an HSCT treatment, the bone marrow, harboring the diseased cancer cells, is completely destroyed and subsequently replaced by stem cells in the graft from a healthy donor. After an HSCT treatment it usually takes the patient at least six to twelve months to recover to near-normal blood cell levels and immune cell functions. During this period, the patient is highly vulnerable to infections caused by bacteria, viruses and fungi but also to disease relapse.
ATIR101โข (Allodepleted T-cell ImmunotheRapeutics) provides for a safe donor lymphocyte infusion (DLI) from a partially matched (haploidentical) family member without the risk of causing severe Graft-versus-Host-Disease (GVHD). The T-cells in ATIR101โข will help fight infections and remaining tumor cells and thereby bridge the time until the immune system has fully re-grown from stem cells in the transplanted graft.
In ATIR101โข, T-cells that would cause GVHD are eliminated from the donor lymphocytes using Kiadis Pharmaโs photodepletion technology, minimizing the risk of GVHD and eliminating the need for prophylactic immune-suppression. At the same time, ATIR101โข contains potential cancer killing T-cells from the donor that could eliminate residual cancer cells and help prevent relapse of the disease, known as the Graft-versus-Leukemia (GVL) effect.
ATIR101โข, administered as an adjunctive immuno-therapeutic on top of HSCT, provides the patient with functional, mature immune cells from a partially matched family donor that can fight infections and tumor cells but that do not cause GVHD. ATIR101โข thus has the potential to make curative HSCT a viable option to many more patients.
The Company estimates that approximately 35% of patients who are eligible and in urgent need of HSCT will not find a matching donor in time. A partially matched (haploidentical) family donor, however, will be available to over 95% of patients.
ATIR101โข, consisting of donor T-cells that fight infections and residual tumor cells while not eliciting severe GVHD, is designed to result in low relapse rates and low rates of death due to infections, in the absence of severe acute GVHD.
About Kiadis Pharmaย
Kiadis Pharma is focused on cell-based immunotherapy products for the treatment of blood cancers and inherited blood disorders. The Companyโs products have the potential to address the risks and limitations connected with allogeneic hematopoietic stem cell transplantation (HSCT), namely Graft-versus-Host-Disease (GVHD), cancer relapse, opportunistic infections and limited matched donor availability. The Company believes that HSCT could become a first-choice treatment for blood cancers, inherited blood disorders and possibly autoimmune diseases and solid organ transplantations.
On December 5, 2016 at the Annual Meeting of the American Society of Hematology (ASH), the Company reported positive Phase II results with its lead product ATIR101โข in patients with blood cancer. The data showed that ATIR101โข significantly reduced Transplant Related Mortality and significantly improved Overall Survival. In addition, ATIR101โข did not elicit grade III-IV GVHD in any patient. Based on these positive results, a Phase III clinical trial has been initiated. ATIR101โข has been granted Orphan Drug Designations both in the US and Europe.
The Companyโs second product candidate, ATIR201โข, addresses inherited blood disorders with an initial focus on thalassemia, a disease which results in destruction of red blood cells in patients. ATIR201โข Phase I/II clinical development has been initiated recently.
Kiadis Pharma, based in Amsterdam, The Netherlands, was granted an Advanced Therapy Medicinal Product (ATMP) certificate for manufacturing quality and non-clinical data by the European Medicines Agency (EMA). The Companyโs shares are listed on Euronext Amsterdam and Euronext Brussels.
