The official eligibility criteria

Registry text, reproduced exactly. These are the words the trial's sponsor published on ClinicalTrials.gov. They have not been edited, shortened or rewritten, and they are written for researchers rather than for patients.

Inclusion Criteria:

* Locally advanced and unresectable or metastatic HER2-positive advanced breast cancer (aBC), HR-positive/HER2-negative advanced breast cancer, KRAS mutant advanced colorectal cancer (aCRC), or KRAS mutant advanced non-small cell lung cancer (aNSCLC)

* Measurable disease by RECIST v1.1 (except for HR-positive HER2-negative aBC where evaluable bone-only disease is permitted)

* Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-1

* Adequate LVEF assessed by ECHO or MUGA (BBO-10203 + Trastuzumab cohorts only)

* Stable brain metastases

* Patients with HER2-positive aBC: Must have had at least 2 prior lines of anti-HER2-directed therapy. Only 1 prior line is acceptable where there is no other regionally available standard of care (SoC)

* Monotherapy Cohort patients with HR-positive, HER2-negative aBC, KRAS mutant aCRC or aNSCLC: Must have progression on, or disease recurrence after at least one line of SOC treatment or in the opinion of the investigator, would be unlikely to tolerate or derive clinically meaningful benefit from SoC therapy

* BBO-10203 + Fulvestrant combination cohort patients with HR-positive, HER2-negative aBC: confirmed PIK3CA mutation, must have been treated with a CDK4/6i

* BBO-10203 + Fulvestrant + ribociclib combination cohort patients with HR-positive, HER2-negative aBC: confirmed PIK3CA mutation, no prior systemic therapy in the aBC setting permitted

* BBO-10203 + FOLFOX + Bevacizumab combination cohort patients with KRAS mutant aCRC: One prior line of irinotecan-containing therapy for locally advanced or metastatic CRC is allowed but not required

Exclusion Criteria:

* Patients with KRAS mutant aCRC who have KRAS G12R mutation, BRAFV600E mutation, HER2amp, or dMMR/MSI-H tumors

* Patients with KRAS mutant aNSCLC who have KRAS G12R mutation, or tumors with other targetable driver mutations (eg, EGFR, anaplastic lymphoma kinase, ROS1/BRAF/RET/MET/EGFR exon20 insertion/NTRK/HER2)

* Patients with untreated and/or non-stable brain metastases

Other inclusion/exclusion criteria are specified in the protocol

Voxsanity reformats data from public registries into this layout. It does not edit, interpret or add to what the registry published.

Not medical advice.

Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.
