First-in-Human Study of OKI-219 in Advanced Solid Tumors and Advanced Breast Cancer
United States, Belgium, France200 participantsStarted 2024-02-26
Plain-language summary
OKI-219-101 is a Phase 1a/1b, open-label, multicenter, dose-escalation study designed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PDx), and efficacy of OKI-219 as monotherapy and in combination with other anti-cancer drugs. Phase 1a (Part A) will investigate escalating doses of OKI-219 monotherapy, and Phase 1b will investigate OKI-219 (at a tolerated dose determined in Part A) in combination with fulvestrant (Part B), trastuzumab and tucatinib (Part C), atirmociclib (Part D), and ribociclib and fulvestrant (Part E). Participants will continue to receive study treatment until disease progression, intolerable toxicity, or other study treatment withdrawal criteria are met.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Key Inclusion Criteria:
* Participants with advanced solid tumors with documented evidence of a PI3KαH1047R mutation in tumor tissue and/or blood (ie, ctDNA).
* Eastern Cooperative Oncology Group (ECOG) Performance status score of to 1.
* Life expectancy \> 12 weeks for Part A and \> 6 months for Parts B, C, D, and E in the opinion of the Investigator.
* Adequate organ and bone marrow function
* Have adequate archival tumor tissue sample available or be approved by the Sponsor for enrollment if no tumor sample is available.
* At least 1 measurable lesion based on RECIST version 1.1.
Additional Cohort-specific key inclusion criteria:
Part A
* Participants with HR+/HER2- locally advanced, unresectable or metastatic breast cancer, must have received at least 1 prior line of hormonal therapy and at least 1 prior line of CDK4/6-inhibitor in the advanced or metastatic setting.
* Participants with HER2+ locally advanced, unresectable or metastatic breast cancer, must have received prior taxane, trastuzumab, pertuzumab, and tucatinib. Prior trastuzumab deruxtecan is allowed but not required.
* Participants with HER2-low breast cancer must have received prior trastuzumab deruxtecan.
* Participants with colorectal cancer must have KRAS wild-type disease.
Part B
* Participants with locally advanced, unresectable or metastatic HR+/HER2- breast cancer must have received at least 1 prior line of hormonal therapy in the advanced or metastatic setting and at least 1 prior CDK4/6-inhibi…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Identify maximum tolerated dose (MTD) of OKI-219 in monotherapy
Timeframe: Cycle 1 (First 28 days on treatment)
2
Assess safety of OKI-219 as monotherapy or in combination with other anti-cancer therapies: incidence of SAEs
Timeframe: Through 30 days after last dose, an average of 1 year
3
Assess safety of OKI-219 as monotherapy or in combination with other anti-cancer therapies: incidence of Grade 2 or greater treatment emergent adverse events
Timeframe: Through 30 days after last dose, an average of 1 year
4
Assess rate of dose modifications during treatment with OKI-219 as monotherapy or in combination with other anti-cancer therapies
Timeframe: Through last study dose, an average of 1 year
