Study summary

CRC is the third most common type of cancer diagnosed worldwide with developed countries at highest risk. The purpose of this study is to assess adverse events and change in disease activity when telisotuzumab adizutecan is given in combination with oxaliplatin, fluorouracil (5FU), leucovorin (LV) (FOLFOX), and bevacizumab or panitumumab.

Telisotuzumab adizutecan is an investigational drug being developed for the treatment of mCRC. Fluorouracil and leucovorin are drugs approved for the treatment of mCRC. This study will be divided into two stages, with the first stage treating participants with increasing doses of telisotuzumab adizutecan with FOLFOX and bevacizumab or 5FU/LV and panitumumab until the dose reached is tolerable and expected to be efficacious. Participants will then be randomized into 3 groups called treatment arms where one group will receive one of two optimized doses of telisotuzumab adizutecan from the dose escalation phase with FOLFOX and bevacizumab or 5FU/LV and panitumumab, or a comparator of FOLFOX and bevacizumab or panitumumab. Approximately 390 adult participants with mCRC will be enrolled in the study in 100 sites worldwide.

In the dose escalation stage participants will be treated with increasing intravenous (IV) doses of telisotuzumab adizutecan with FOLFOX and bevacizumab or 5FU/LV and panitumumab until the dose reached is tolerable and expected to be efficacious. In the dose optimization stage participants will be receive FOLFOX or receive 5FU/LV, but with one of two optimized doses of telisotuzumab adizutecan, or a comparator of FOLFOX and bevacizumab/pantitumumab. The study will run for a duration of approximately 6 years.

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at an approved institution (hospital or clinic). The effect of the treatment will be frequently checked by medical assessments, blood tests, questionnaires and side effects.

Eligibility

Primary outcome measure(s)

• Objective Response (OR) as Assessed by the Investigator confirmed complete response (CR) or partial response (PR) as assessed by the investigator per response evaluation criteria in solid tumors (RECIST), version 1.1. — Up to 24 Weeks
  OR is defined as confirmed CR or PR as assessed by the investigator per RECIST, version 1.1.
• Number of Participants with Adverse Events (AE)s — Up to Approximately 6 Years
  An adverse event is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment.
