A Pharmacokinetic and Metabolism Study of 14C-labeled RO5185426 on Patients With Metastatic Melanoma
March 9, 2023 updated by: Hoffmann-La Roche
A Phase I, Open-label, Excretion Balance, Pharmacokinetic and Metabolism Study After Single Oral Dose of 14C-labeled RO5185426 in Previously Treated and Untreated Patients With Metastatic Melanoma
This open-label, non-randomized study will assess the mass balance, metabolism, routes and rates of elimination as well as efficacy and safety of RO5185426 (RG7204; PLEXXIKON; PLX4032) in previously treated or untreated patients with metastatic melanoma.
Patients will receive continuous twice daily oral treatment with RO5185426.
On Day 15, a 14C-labeled dose will be administered.
Anticipated time on study treatment is until disease progression occurs.

Time Frame: From Baseline then Day 1 of Cycle 3 thereafter, Day 1 of every other cycle (every 2 months) until disease progression, withdrawal from study or death (maximum 841 days)
|
Best overall response (according to Response Evaluation Criteria In Solid Tumors 1.1 criteria) was defined as best response recorded from start of treatment until disease progression which included complete response (CR) or partial response (PR) that had been confirmed by second tumor assessment no less than (<) 4 weeks after criteria for response were first met.
Confirmed CR: disappearance of all target and non-target lesions; no new lesions, and any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 millimeters (mm).
Confirmed PR: at least 30% decrease in sum of diameters of target lesions (taking as reference the baseline sum diameters), no progression in non-target lesions, and no new lesions.
Disease progression: at least 20% increase in sum of diameters of target lesions compared to smallest sum of diameters on-study and absolute increase of at least 5 mm, progression of existing non-target lesions, or presence of new lesions.

From Baseline then Day 1 of Cycle 3 thereafter, Day 1 of every other cycle (every 2 months) until disease progression, withdrawal from study or death (maximum 841 days)
|
Overall Survival
Time Frame: From Baseline then Day 1 of Cycle 3 thereafter, Day 1 of every other cycle (every 2 months) until death (maximum 841 days)

Overall survival was defined as the time from the date of first treatment to the date of death, regardless of the cause of death.
