Primary
| Measure | Time frame | Description |
|---|---|---|
| Progression Free Survival (PFS) Rate | up to 18 weeks | The 18-week PFS was defined as the percentage of participants who did not have a progression event at week 18. Participants who progressed, died, had response assessment of unknown (UNK) or discontinued before 18 weeks of observation without progression were counted as failure. Progressive disease was assessed as per investigator assessment using Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. |

|---|---|---|
| Disease Control Rate (DCR) | Baseline and every 6 weeks until disease progression, up to 18 weeks | DCR was defined as the percentage of participants with a best overall response of CR or PR or stable disease (SD). |
| Duration of Response (DR) | up to 18 weeks | Duration of response was defined for participants with a CR or PR as the time from the date of the first documented response (CR or PR) to the date of the first documented progression or death due to disease. If a participants did not have a progression event, duration of response was censored at the date of the last adequate tumor assessment before the data analysis cut-off date or the antineoplastic therapy start date or the death date. |

| Progression Free Survival (PFS) | up to 18 weeks | PFS was defined as the time from the date of start of treatment to the date of the first documented progression or death due to any cause. If a participant did not have an event, PFS was censored at the date of last adequate response assessment before the data analysis cut-off date or the start date of new antineoplastic therapy after study drug discontinuation. |
| Number of Participants With Adverse Events, Serious Adverse Events and Deaths | up to 30 days after the last dose of study drug, up to 18 weeks | Adverse event monitoring was conducted throughout the study. |
| Overall Survival (OS) | up to 18 weeks | OS was defined as the time from date of treatment to the date of death from any cause. If a participant was not known to have died at the date of analysis cut-off, the OS was censored at the last date of contact. |

Participant flow
Recruitment details
Participants were treated with TKI258 until disease progression, unacceptable toxicity, death or discontinuation due to any other reason. All participants were followed for at least 30 days after their last dose of study drug for safety assessment.
Pre-assignment details
If a participant didn't discontinue study drug due to disease progression, death, lost to follow-up or withdrawn consent to post treatment tumor assessment, then tumor assessments continued every 6 weeks until the start of new anti-cancer therapy, disease progression, death, lost to follow-up or withdrawn consent to tumor status follow-up.

Outcome results
Progression Free Survival (PFS) Rate
The 18-week PFS was defined as the percentage of participants who did not have a progression event at week 18. Participants who progressed, died, had response assessment of unknown (UNK) or discontinued before 18 weeks of observation without progression were counted as failure. Progressive disease was assessed as per investigator assessment using Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.
Time frame: up to 18 weeks
Population: Primary endpoint analysis set (PEAS): The PEAS included all participants who received at least one dose of study medication and had measurable disease at baseline as confirmed by a local Investigator.
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| FGFR2 (MUT) | Progression Free Survival (PFS) Rate | 31.8 Percentage of participants |
| FGFR2 (WT) | Progression Free Survival (PFS) Rate | 29.0 Percentage of participants |
Disease Control Rate (DCR)
DCR was defined as the percentage of participants with a best overall response of CR or PR or stable disease (SD).
