First DKMS clinical trial improves therapy for blood cancer patients

• Faster transplantation • Less drug-related side effects • Reduced treatment costs


London, 2 February 2023. Saturday 4 February 2023 is World Cancer Day, which focuses on the prevention, research and treatment of cancer. The first ever completed clinical trial facilitated and organised by DKMS may be practice-changing for patients suffering from acute myeloid leukaemia (AML). Patients in urgent need of a stem cell transplant could be transplanted much faster and benefit from shorter hospital stays as well as fewer side effects by not having to undergo lengthy high-dose chemotherapy.

This important conclusion was reached by the researchers at the University Hospital Carl Gustav Carus Dresden, the National Center for Tumor Diseases Dresden (NCT/UCC), and the University Hospital Münster (Germany). The trial was supported by the Study Alliance Leukemia (SAL), the Cooperative German Transplant Study Group, and the Gert and Susanna Mayer Foundation.

The ASAP study was a Germany-wide randomised controlled trial in which 18 clinics participated. The goal was to get AML patients to stem cell transplantation as soon as possible without requiring complete remission before allogeneic stem cell transplantation. Attempting complete remission prior to transplantation has been considered the standard of care.

“The surprising finding of the clinical trial was that patients did not benefit from a full course of chemotherapy prior to transplantation to induce complete remission. Rather the study suggests, that if a matched donor is available, 12 days of preparatory chemotherapy followed by immediate transplantation yields comparable treatment outcomes with fewer side effects and shorter hospital stays,” summarised Professor Dr Johannes Schetelig who heads the Clinical Trials Unit of DKMS as well as the Stem Cell Transplantation Unit at the University Hospital Carl Gustav Carus Dresden, Germany.

If the results are translated into clinical practice, numerous patients worldwide may benefit in the future, as patients who urgently need a stem cell transplant could be transplanted much faster, without the stressful phase of salvage chemotherapy and long hospital stays. Even with intensive chemotherapy, the previously targeted complete remission can only be achieved in about 50 percent of patients. If the corresponding treatment is unsuccessful, most patients have so far received further anti-leukemic drugs with potentially burdensome side effects, depending on their overall state of health. Immediate transplantation could also allow more patients access to this potentially life-saving treatment.

The results of the ASAP trial demonstrate that AML patients will have the same chances of cure in the future without having to be hospitalized longer than necessary and the cost of therapy will be significantly lower.

Why is it important that DKMS as a non-profit organisation funds clinical research?

“It is our declared goal to improve the survival of people with blood cancer. To achieve this, it is essential to continuously develop existing forms of treatment and to constantly explore new approaches in blood cancer therapy. To fulfil our life-saving mission, we invest in science and research: with success, less side effects and hospital stays with equally good treatment results,” highlights Dr Elke Neujahr, Global CEO DKMS.

DKMS is an economically operating non-profit organisation and its revenues go to social or scientific purposes. This way, the organisation is able to financially support meaningful projects that help blood cancer patients around the world.

"Often, sponsors of clinical research pursue economic interests. It is therefore less common to conduct a clinical trial that challenges a standard medical intervention than to investigate new therapeutic approaches. That’s why it’s necessary for non-profit organisations like DKMS to also conduct clinical research. This way, we can help ensure that patients receive the best possible treatment and that we actually advance patient care," said Dr. Alexander Schmidt, Global Chief Medical Officer at DKMS.

The organisation also employs a wide range of programmes and services to improve the access to transplantation for patients in low- and middle-income countries who would otherwise not receive treatment. For example, DKMS provides free HLA typing to identify family donors and funds stem cell transplantation for children with thalassemia in India to lessen the burden for patients and their families. The organisation has also funded a transplant station in Bangalore where up to 120 children annually get their second chance at life. In Poland, DKMS is helping to ensure that hospitals are better equipped to treat leukaemia patients. And in Chile, the lack of resources and infrastructure are main barriers for blood stem cell transplantation. There, the organisation supports patients and the healthcare system so that more people can receive life-saving treatment.

About DKMS

DKMS is an international non-profit organisation dedicated to saving the lives of patients with blood cancer. Founded in Germany in 1991 by Dr Peter Harf, DKMS and the organisation’s 1,000 employees have since relentlessly pursued the aim of giving as many patients as possible a second chance at life. With over 11,5 million registered donors, DKMS has succeeded in doing this more than 100,000 times to date by providing blood stem cell donations to those in need.

This accomplishment has led to DKMS becoming the global leader in the facilitation of unrelated blood stem cell transplants. The organisation has offices in Germany, the US, Poland, the UK, Chile and South Africa. In India, DKMS has founded the joint venture DKMS-BMST together with the Bangalore Medical Services Trust. International expansion and collaboration are key to helping patients worldwide because, like the organisation itself, blood cancer knows no borders.

DKMS is also heavily involved in the fields of medicine and science, with its own research unit focused on continually improving the survival and recovery rate of patients. In its high-performance laboratory, the DKMS Life Science Lab, the organization sets worldwide standards in the typing of potential blood stem cell donors.
