We reached significant milestones in our clinical programmes and also successfully listed the Company on Euronext Amsterdam and Euronext Brussels. The financial results are fully in line with our guidance and projections and show that Kiadis Pharma has been conscious and diligent on expenses whilst progressing with the development of its lead product ATIR101™ for patients suffering from acute leukaemia towards its last phase of clinical development. With a healthy year-end cash position, we are well positioned to begin Phase I/II clinical development with ATIR201™ for thalassaemia, scale-up our manufacturing and begin enrolment into our pivotal Phase III trial with ATIR101™. I would like to thank our investors for their continued support and look forward to providing further updates in due course.”

About Kiadis Pharma

Kiadis Pharma is a clinical stage biopharmaceutical company focused on research, development and future commercialisation of cell-based immunotherapy products for the treatment of blood cancers and inherited blood disorders. The Company believes that its innovative products have the potential to address the current risks and limitations connected with allogeneic hematopoietic stem cell transplantation (HSCT), being graft-versus-host disease (GVHD), cancer relapse, opportunistic infections and limited matched donor availability. HSCT is generally regarded as the most effective curative approach to blood cancers and certain inherited blood disorders and the Company expects that HSCT could become a first-choice treatment for blood cancers and inherited blood disorders once current risks and limitations are addressed, thereby meeting a significant unmet medical need with its products.

In April 2016, the Company reported positive results on the primary endpoint of its single dose Phase II trial with its lead product ATIR101™, which allows a safe donor lymphocyte infusion (DLI) from a partially matched (haploidentical) family member without the risk of causing severe GVHD. The study was designed as an open-label trial in patients with blood cancer who had not found a matching donor and where a partially matched (haploidentical) family member was used as donor for HSCT. The primary endpoint of the trial was Transplant Related Mortality (TRM) within six months-post HSCT. The data confirmed that ATIR101™ can be safely infused, does not cause grade III-IV GVHD and shows a significant reduction in TRM and a significant improvement in Overall Survival (OS) in comparison to a historical control group of patients undergoing a T-cell depleted haploidentical donor transplantation only.

In addition, the Company is enrolling blood cancer patients in a further Phase II clinical trial to study the safety and efficacy of administrating a second dose of ATIR101™ to further improve the HSCT outcome.

ATIR101™ has been granted Orphan Drug Designations both in the US and Europe.

The European Medicines Agency (EMA) has issued an Advanced Therapy Medicinal Product (ATMP) certificate for manufacturing quality and non-clinical data to the Company, and to date Kiadis Pharma is one of only five companies that have received such a certificate.

ATIR201™ will be developed for inherited blood disorders with an initial focus on thalassaemia, an inherited blood disorder which results in improper oxygen transport and destruction of red blood cells in a patient. ATIR201™ is expected to enter Phase I/II clinical development for thalassaemia in the second half of 2016. Kiadis Pharma is collaborating with the Thalassaemia International Federation (TIF), an internationally renowned organisation that seeks to address the needs of patients, carers, healthcare professionals and the general public in the area of thalassaemia.

Kiadis Pharma is based in Amsterdam, the Netherlands and its shares are listed on Euronext Amsterdam and Euronext Brussels. Further information can be found at: www.kiadis.com
