简要总结
The purpose of this study is to evaluate the safety of a new medicinal drug SYD985 at different dose levels in patients with cancer, to understand how SYD985 is handled by the body and to evaluate the effect of SYD985 on the cancer.
详细描述
Cancer cells can have different kinds of proteins on their cell surface; one of these is the protein HER2. HER2 plays an important role in the development of cancer. High expression of HER2 is related to poor prognosis. Although several cancer drugs are available that work via the HER2 protein, a substantial portion of these patients still does not benefit from these treatments.
The new cancer drug SYD985 is being developed by Synthon Biopharmaceuticals B.V. SYD985 is an antibody-drug conjugate and consists of two parts: an antibody and a linker-drug moiety containing a toxin. The antibody part binds to HER2 on the surface of the cancer cell. When SYD985 binds to this cancer cell, it will be internalized by the cell. After proteolytic cleavage of the linker, the toxin will be split off in the cell and the cancer cell will be killed. Thus, SYD985 can be considered as a form of targeted chemotherapy.
This is the first study in which SYD985 is administered to humans. The study consists of two parts:
Part I is the dose-escalation part in which a low dose of SYD985 is given to three cancer patients. If it is well tolerated, a higher dose of SYD985 will be given to 3 other cancer patients. This will continue until a further dose increase is not safe anymore.
In Part II of the study, several groups of patients with a specific type of cancer will receive the SYD985 dose which has been selected for further evaluation.
