A Study of Pevonedistat in People With Blood Cancers or Solid Tumors With Kidney or Liver Problems

Pevonedistat is a medicine to treat people with blood cancers or solid tumors. The main aim of the study is to learn about the levels of pevonedistat in the blood of participants with blood cancers or solid tumors, who also have severe kidney problems or mild to moderate liver problems. The information from this study will be used to work out the best dose of pevonedistat to give people with these conditions in future studies. At the first visit, the study doctor will check who can take part in the study. This study is in 2 parts: A and B. Part A Participants will be placed into 1 of 4 treatment groups depending on how severe their kidney and liver problems are. All participants will receive 1 dose of pevonedistat as a slow injection in their vein (infusion). Then, the study doctors will check the levels of pevonedistat in the blood of the participants for 3 days after the infusion. They will also check if the participants have any side effects from pevonedistat. Participants will be asked to continue to Part B. Those who don't want to continue will visit the clinic 30 days later for a final check-up. Part B Participants who agree to participate into Part B will receive an infusion of pevonedistat on specific days during a 21-day or 28-day cycle. The cycle time will depend on what type of cancer the participants have. Participants will also be treated with standard of care medicines for their kidney and liver problems during this time. In the first cycle, the study doctors will also check the levels of pevonedistat in the blood and urine of participants for 3 days after the infusion. Participants will continue with cycles of treatment together with standard of care medicines until their condition gets worse or they have too many side effects from the treatment. When treatment has finished, participants will visit the clinic 10 days later for a final check-up.
