Trial Design
Clinical Trial Id:NA
Agent:RAF265
Target:mRNA of RAF protooncogene serine/threonineprotein kinase
Cancer Type:melanoma
Cancer Subtype:advanced cutaneous melanoma
Therapy Type:mono
Therapeutic Combination Type:NA
Therapeutic Combination Content:NA
Study Type:the firstinhuman (FIH)phase I study
Key Patients Feature:patients with advanced cutaneous melanoma
Biomarker:Mutations in BRAF and NRAS
Biomark Analysis:NA
Control Group Info:single arm
Treatment Info:use different schedules for its administration: Daily (QD), weekly and intermittent. Results for QD dosing are presented here, where pts were treated by a loading dose (LD) follotheyd by continuous QD RAF265 oral solution at escalated dose levels (DLs).
Primary End Point:the maximum tolerated dose (MTD), safety, PK, PD and antitumor activity
Secondary End Point:NA
Patients Number:76
Trial Results
DLT_MTD:The MTD of oral RAF265 on a continuous daily schedule was defined at 48mg.
Objective Response Rate:The overall response rate by RECIST 1.0 was 6/37 (16%) for mut BRAF pts and 4/30 (13%) for wt (3)/unknown (1) BRAF pts.
Disease Control Rate: Mutations in BRAF and NRAS were detected 59% and 16% of evaluated tumor samples (n=70), respectively. 18FFDG uptake decrease from baseline (2.6 to 57.2%) was noted in 16/31 (52%) mut BRAF pts, with partial tumor metabolic response (SUVmax more than and equal to 25%) in 8/31 (26%). Plasma angiogenesis markers showed decreases of sVEGFR2 and increases in PlGF across DLs.
Median Time to Progression:NA
Median PFS A vs. C:NA
Median OS A vs. C:NA
Adverse Event(agent arm):Of 71 evaluable pts, six experienced dose limiting toxicities within 1st cycle (28 days): Pulmonary embolism (2), visual disturbances (2), hyperlipasemia (1), diarrhea (1) and ataxia (1). Thrombocytopenia Grade 3 (6) and 4 (2) occurred at 67mg QD in 2nd cycle and was also considered dose limiting.
Conclusions:The MTD of oral RAF265 on a continuous daily schedule was defined at 48mg. Clinical activity was observed at multiple dose cohorts in pts with BRAF mut and wt melanoma. Since RAF265 QD at 67mg consistently caused delayed dose limiting hematologic toxicity, an intermittent schedule is being explored.
