Study Summary
The main purpose of this study is to learn more about the safety, side effects, and effectiveness of LOXO-435.
The study will be conducted in 2 phases:
Dose escalation (1a) and dose expansion (1b).
Phase 1a will assess safety, tolerability, and pharmacokinetics of LOXO-435 to determine the recommended phase 2 dose (RP2D).
Phase 1b will include 4 dose expansion cohorts of patients with prespecified activating FGFR3 alterations to evaluate the efficacy and safety of LOXO-435 at the RP2D.
Cohort B will enroll pts with mUC and includes three cohorts to evaluate LOXO-435 as monotherapy (B1, B2) and in combination with pembrolizumab (B3).
Cohort C will enroll pts with non-UC advanced solid tumors and includes a cohort to evaluate LOXO-435 as monotherapy (C1).
To evaluate LOXO-435 in patients with cancer.
To report initial clinical data from the phase 1 dose escalation cohort of LY3866288 in FGFR3-altered advanced solid tumors.
Medical Condition
The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.
Phase
The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Requirements information
Inclusion criteria
- Have solid tumor cancer with an FGFR3 pathway alteration on molecular testing in tumor or blood sample that is deemed as actionable
- Cohort A1: Presence of an alteration in FGFR3 or its ligands
- Cohort A2, B2, B3, and B5: Histological diagnosis of urothelial cancer (UC) that is locally advanced or metastatic with a qualifying FGFR3 genetic alteration
- Cohorts B1 and B4: Histological diagnosis of urothelial cancer that is locally advanced or metastatic
- Cohort C1: Must have histological diagnosis of a non-urothelial solid tumor malignancy that is locally advanced or metastatic with a qualifying FGFR3 genetic alteration
- Measurability of disease:
- Cohort A1 and B3: Measurable or non-measurable disease as defined by Response Evaluation Criteria in Solid Tumors v 1.1 (RECIST v1.1)
- Cohorts A2, B1, B2, B4, B5, and C1: Measurable disease required as defined by RECIST v1.1
- Have adequate tumor tissue sample available. Participants with inadequate tissue sample availability may still be considered for enrollment upon review
- Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 for Cohorts A1, A2, B3, and B5
- Less than or equal to 2 for Cohorts B1, B2, B4, and C1
- Prior Systemic Therapy Criteria:
- Cohort A1/C1: Participant has received all standard therapies for which the participant was deemed to be an appropriate candidate by the treating Investigator; OR the participant is refusing the remaining most appropriate standard of care treatment; OR there is no standard therapy available for the disease. There is no restriction on number of prior therapies.
- Cohort A2, B2, B3 participants must have received at least one prior regimen, and cohorts B1 and B4 participants at least 2 prior regimens, in the locally advanced or metastatic setting
- There is no restriction on number of prior therapies
- Cohort B5: Participants have not received prior systemic therapy for locally advanced or metastatic UC
- FGFR inhibitor specific requirements:
- Cohort A1/A2/B3: Prior FGFR inhibitor treatment is permitted but not required
- Cohort B1/B4: Participants must have been previously treated with erdafitinib
- Cohort B2, B5, and C1: Participants must be FGFR inhibitor naïve
Exclusion criteria
- Participants with primary central nervous system (CNS) malignancy
- Untreated or uncontrolled CNS metastases
- Current evidence of corneal keratopathy or retinal disorder. Individuals with asymptomatic ophthalmic conditions may be eligible
- Any serious unresolved toxicities from prior therapy
- Significant cardiovascular disease
- Prolongation of the QT interval corrected for heart rate using Fridericia's formula (QTcF)
- Active uncontrolled systemic infection or other clinically significant medical conditions
- Participants who are pregnant, lactating, or plan to breastfeed during the study or within 6 months of the last dose of study treatment. Participants who have stopped breastfeeding may be enrolled
