A plain-language read of the study's public EU CTIS listing. The study team confirms the details.

Who can take part

You may be able to join if

1. Ability to comprehend and willingness to sign a written ICF for the study.
10. Should have received prior treatment with mirvetuximab soravtansine if the tumor is positive for FRα, unless there is an exception for its use on medical grounds. Medical exceptions include: active or chronic corneal disorders, history of corneal transplantation, or active ocular conditions requiring ongoing treatment/monitoring (eg, uncontrolled glaucoma, wet age-related macular degeneration requiring intravitreal injections, active diabetic retinopathy with macular edema, macular degeneration, presence of papilledema, and/or monocular vision).
11. Have had documented disease progression during or after their last line of anticancer therapy prior to study entry.
12. Measurable disease per RECIST v1.1 on CT or MRI. Note the following: • Lesions situated in a previously irradiated field are considered measurable if progression has subsequently been demonstrated. • Tumor lesions that have been biopsied should not be selected as target lesions unless post-biopsy imaging confirms that it still qualifies as a RECIST-defined measurable lesion.
13. Ability to take medication orally.
14. ECOG performance status of 0 or 1 (see Table 23 in the Protocol).

You likely can't join if

1. Have endometrioid, clear cell, mucinous, or sarcomatous histology, mixed tumors containing any of these histologies, or low-grade/borderline ovarian cancer.
18. Any radiation therapy within 14 days before the first dose of study treatment. Note: Radiation-related toxicities must have improved to ≤ Grade 1.
19. Current treatment with another investigational medication or having been treated with an investigational medication other than the study treatment within 5 half-lives or 28 days (whichever is shorter) before the first dose of study treatment.
2. Have primary platinum-refractory disease, defined as progression on or within 3 months after the last dose of first-line platinum-containing therapy.
20. Current use of prohibited medication as described in Section 6.6.3 in the Protocol.
21. For participants assigned to receive INCB123667 only: current treatment with any strong CYP3A4/CYP3A5 inhibitor or inducer (Appendix G in the Protocol) or having been treated with a strong tYP3A4/CYP3A5 inhibitor or inducer within 5 half-lives or 28 days (whichever is shorter) before the first dose of INCB123667.

9. Should have received prior treatment with bevacizumab unless there was a contraindication for its use.
