Study of a New Treatment Called ONM-501 Alone and in Combination with Immunotherapy for Triple Negative Breast Cancer, Advanced Solid Tumors and Lymphomas

About the Study

This is an open-label, non-randomized study.

• All people will receive the study drug ONM-501, injected into their tumor, either alone or in combination with Cemiplimab, a PD-1 checkpoint inhibitor.
• The study will have different groups of participants. People will be assigned to a group based on their tumor testing.
  • The dose escalation groups will establish the ideal dose of ONM-501 alone or in combination with Cemiplimab.
  • The dose expansion groups will include additional patient populations.
  • Everyone will keep taking the medication until their cancer gets worse, the treatment causes severe side effects, or they choose to stop the study. 

What the Study Involves

There are 3 groups to the study:

Group 1

• ONM-501 will be injected directly into the tumor once per week for three weeks, followed by three weeks without ONM-501 administration. Each dosing cycle will be 21 days.

Group 2

• ONM-501 will be injected directly into the tumor once per week for three weeks followed by three weeks without ONM-501 administration. Each dosing cycle will be 21 days. The combination drug, Cemiplimab (an immunotherapy), will be injected into the vein once every three weeks.

Group 3

• Once the recommended doses are determined for ONM-501 by itself or in combination with Cemiplimab (an immunotherapy), the expansion phase of the study will be initiated. The expansion phase will enroll people in one to three groups based on tumor indication.
