Brief Summary:
The main purpose of the study is to evaluate the safety and tolerability of HRO761 and identify the recommended dose(s), i.e., the optimal safe and active dose of HRO761 alone or in combination with tislelizumab or irinotecan that can be given to patients who have cancers with specific molecular alterations called MSIhi (Microsatellite Instability-high) or dMMR (Mismatch Repair Deficient) that might work best to treat these specific cancer types and to understand how well HRO761 is able to treat those cancers.

Condition or disease Intervention/treatment Phase
MSIhi or dMMR Advanced Unresectable or Metastatic Solid Tumors, Including Colorectal Cancers Drug: HRO761 Biological: tislelizumab Drug: irinotecan Phase 1

Detailed Description:

The new drug being tested in the study, HRO761, is an oral drug that acts on a protein called Werner (WRN), which may contribute to cancer growth. By acting on WRN, HRO761 may be able to stop the growth of the cancer.

This is the first time HRO761 is given to patients and the first time HRO761 is used in combination with tislelizumab or irinotecan.

Tislelizumab has been used in other cancer studies in the past few years and irinotecan is a drug approved in several countries and is used as standard treatment for certain types of cancer (e.g., colon cancer and small cell lung cancer).

This research study will consist of various treatment arms to investigate HRO761 as single agent and in the combinations.

For HRO761 single agent, the research will be done in two parts the first part is called "dose escalation" and the second part is called "dose optimization" In the dose escalation part, different groups of people will be given different doses of HRO761 to understand how the body reacts to different doses of the drug and how well the drug acts against the cancer. During the dose optimization part, the selected doses will be tested in more patients until a recommended dose(s) is found.

The combinations of HRO761with tislelizumab or irinotecan will also first be tested in a dose escalation part to find the recommended doses of HRO761 in these combinations.

Once the recommended doses are determined, more people may be treated with HRO761 alone or together with tislelizumab or irinotecan to further assess the study treatment effects against various types of MSIhi or dMMR cancers. This part is called dose expansion.

For this research, a number of blood and tissue samples will be collected during the study. Patients may be asked to come approximately 8 times to the clinic during the first 8 weeks and approximately every 2 or 4 weeks thereafter.

Patients will be in the study as long as their study doctor believes that they may be benefiting from the study treatment, unless the patient decides to stop study treatment.

Masking Description:

This is an open label study. Treatment will be open to patients, Investigator staff, persons performing the assessments and the Sponsor clinical trial team.

For the dose escalation and dose expansion, no randomization will be performed. For the dose optimization (HRO761 single agent arm only), patients will be equally randomized to the two selected HRO761 single agent treatment dose levels.
