|
|
|
|
Radiographically measurable disease (per RECIST v1.1 or RANO for primary brain tumors). Tumor lesions located in a previously irradiated area, or in an area subjected to other loco-regional therapy, are considered measureable if progression has been clearly demonstrated in the lesion |
|
|
|
|
|
Documentation of an FGFR1-3 gene mutation or translocation (Section 8.5.1 and Appendix C). Participants will be assigned to 1 of 3 cohorts |
|
|
|
|
|
Cohort A: FGFR1-3 in-frame fusions or FGFR2 intron 17 rearrangements |
|
|
|
|
|
Cohort B: Known/predicted activating point mutations in FGFR1-3 (excluding kinase domain, see Appendix C) |
|
|
|
|
|
Cohort C: Any FGFR1-3 point mutations in the kinase domain or FGFR1/FGFR3 rearrangements with unknown partners and variants of unknown significance not included in Appendix C |
|
|
|
|
|
Must have objective progression after at least 1 prior therapy, and must have no therapy available that is likely to provide clinical benefit. Participants who are intolerant to or decline the approved therapy are eligible only if they have no therapy available that is likely to provide clinical benefit |
|
|
|
|
|
ECOG performance status 0 to 2 |
|
|
|
|
|
Baseline archival tumor specimen (if less than 12 months from date of screening) or willingness to undergo a pretreatment tumor biopsy to obtain the specimen. Must be a tumor block or approximately 15 unstained slides from biopsy or resection of primary tumor or metastasis |
|
|
|
|
|
Willingness to avoid pregnancy or fathering children based on the criteria below |
|
|
|
|
|
Men must agree to take appropriate precautions to avoid fathering children (with at least 99% certainty) from screening through 90 days after the last dose of study drug(s)/treatment and must refrain from donating sperm during this period. Permitted methods that are at least 99% effective in preventing pregnancy (see Appendix A) should be communicated to the participants and their understanding confirmed |
|
|
|
|
|
Women of childbearing potential must have a negative serum pregnancy test at screening and before the first dose on Day 1 and must agree to take appropriate precautions to avoid pregnancy (with at least 99% certainty) from screening through safety follow-up. Permitted methods that are at least 99% effective in preventing pregnancy (see Appendix A) should be communicated to the participants and their understanding confirmed |
|
|
|
|
|
Women of nonchildbearing potential (ie, surgically sterile with a hysterectomy and/or bilateral oophorectomy OR ≥ 12 months of amenorrhea) are eligible |
