NCT ID NCT06585488

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early This study
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This early-phase study tested a new drug called BGB-53038, which blocks a family of KRAS proteins that help some cancers grow. It was given alone or with other drugs to 47 people with advanced solid tumors (like lung, colon, or pancreatic cancer) that have KRAS mutations. The main goals were to check safety and find the right dose, but the study was stopped early, so results are limited.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
BGB-53038 (a Pan-KRAS inhibitor pill), sometimes combined with tislelizumab or cetuximab infusions
What this could lead to
If it works, this could point toward a new treatment option for several hard-to-treat cancers with KRAS mutations.
What could go wrong
This is a very early (phase 1) trial that was terminated, so results are limited. The drug may not prove effective or safe in larger studies.

Eastern Cooperative Oncology Group (ECOG) Performance Status ≤ 1. 3. Participants must have evidence of a KRAS mutation or wild-type amplification (copy number ≥ 8) based on testing of either tumor tissue or liquid biopsy (blood or plasma) as determined by local laboratory 4. Able to provide an archived tumor tissue sample or fresh biopsy sample. 5. ≥ 1 measurable lesion per RECIST v1.1. 6. Adequate organ function. 7. Females of childbearing potential must be willing to use a highly effective method of birth control for the duration of the study, for \> 7 days after the last dose of BGB-53038, \> 120 days after the last dose of tislelizumab, or \> 2 months after the last dose of cetuximab, whichever is later 8. Nonsterile males must be willing to use a highly effective method of birth control for the duration of the study treatment period and for ≥ 4 months after the last dose of study drug(s). Exclusion Criteria: 1. Participants with tumors harboring KRAS G12R mutation. 2. Participants who have prior therapy with other anti-RAS treatment, including, but not limited to, therapy targeting specific KRAS allele mutation inhibitors, pan-KRAS inhibitors, and other pan-RAS inhibitors 3. Participants with active leptomeningeal disease or uncontrolled, untreated brain metastasis. Participants with a history of treated and, at the time of screening, stable CNS metastases are eligible, provided they meet select criteria. 4.
