Background and study aims
In cancer chemotherapy, the most serious hematologic toxicity (problem with the blood)is neutropenia, a fall in the number of a particular type of white blood cell (WBC) essential for the body's immune response. Neutropenia often limit how big a dose a patient can receive and for how long they can tolerate chemotherapy. The degree and duration of neutropenia determine the risk of infection. Myelo001, a small molecule that is administered as a tablet, has been shown in chemotherapy- or radiotherapy-induced myelosuppression (decrease in the production of cells responsible for immunity) to stimulate differentiation (production) of peripheral white blood cells (WBC) and bone marrow cells. The purpose of the MyeloConcept study is to determine the safety and effectiveness of Myelo001 in preventing or reducing chemotherapy-induced neutropenia and myelosuppression in patients receiving chemotherapy due to breast cancer.
Who can participate?
Women aged >17 years diagnosed with with invasive breast cancer scheduled for chemotherapy treatment with epirubicin / cyclophosphamide.
What does the study involve?
As a basic treatment, all patients are given the epirubicin / cyclophosphamide standard chemotherapy scheduled by the treating physician. All participants are otherwise randomly allocated into one of two groups. Patients in group 1 are given Myelo001 once a day for up to 28 days as well as the chemotherapy treatment. Those in group 2 are given a placebo once a day for 28 days as well as the chemotherapy. All patients fill out diaries every day to report how they are. Changes in the patients' blood count, clinical parameters (for example, symptoms and physiological changes) , as well as safety lab parameters are monitored frequently throughout the study. In a subsequent observational part of the study, blood counts, clinical parameters, and safety lab parameters are analyzed once the patients have stopped taking the study medication . This is to see the effects that may occur after the medication has been stopped and takes place during the second chemotherapy cycle up to the start of the third chemotherapy cycle. Some patients also agree to have blood samples taken for pharmacokinetic analyses (looking at how the study drug is handled in the human body).
What are the possible benefits and risks of participating?
Patients randomized into the Myelo001 group may benefit from increased white blood cells during chemotherapy treatment. This would support the patient's immune system during chemotherapy resulting in less infections. The rate of hospitalization due to severe infections might be reduced. However, as the effect of Myelo001 is still under investigation this effect cannot be ensured.
Patients randomized into the placebo group still receive the standard epirubicin / cyclophosphamide chemotherapy that has been decided for by the respective physician as the most suitable basic treatment. There will be no immediate direct benefit to those patients being randomized into the placebo group. However, results of the placebo group are substantial to evaluate overall study results. Thus, future chemotherapy patients might benefit from those results. Regardless of the group assignment, all patients might benefit from the intensive medical monitoring during the study conduct. In general, Myelo001 is well tolerated and no serious side effects have been reported. In rare cases, skin rash or allergic reactions were observed.

Scientific title | A randomised, double-blind, placebo-controlled, parallel-design, multi-center study to investigate the efficacy to reduce chemotherapy-induced neutropenia (CIN), effects on the haematopoietic system, safety and pharmacokinetics of myelo001 in patients receiving adjuvant or neoadjuvant chemotherapy for the treatment of breast cancer |
Study acronym | MyeloConcept |
Study objectives | The study aims to prove the concept that Myelo001 is effective in reducing chemotherapy-induced neutropenia and myelosuppression. |

Intervention | Participants are randomly allocated to one of two arms: 1. Experimental arm: Myelo001 (Myelo001 100 mg QD) Intervention: Intake of study drug once daily for a maximum of 28 days in addition to Epirubicin and Cyclophosphamide treatment 2. Placebo Comparator Arm: Placebo (Matching Placebo QD) Intervention: Intake of placebo once daily for a maximum of 28 days in addition to Epirubicin and Cyclophosphamide treatment The study comprises: 1. Screening phase up to 23 days 2. Interventional study period d-5/c1A to d22/c1 or last day of IMP (investigational medicinal product) application, whichever occurs later. During this period, IMP will be administered accompanied by frequent study visits. 3. Observational study period starts on d1/c2 with the application of the second chemotherapy cycle and ends on d1/c3 (EOS). Patients will be monitored until all study medication-related adverse effects have been resolved or returned to baseline/grade 1. |
