Description

LXH254 is a potent B/C RAF inhibitor extracted from patent WO2018051306A1, Compound A.

IC50 & Target[1]

c-Raf

 

In Vitro

LXH254 (Compound A) is an adenosine triphosphate (ATP)-competitive inhibitor of BRAF (also referred to herein as b-RAF or b-Raf) and CRAF (also referred to herein as c-RAF or c- Raf) protein kinases. Throughout the present disclosure, LXH254 is also referred to as a c-RAF (or CRAF) inhibitor or a C-RAF/c-Raf kinase inhibitor. In cell-based assays, LXH254 has demonstrated anti-proliferative activity in cell lines that contain a variety of mutations that activate MAPK signaling. Moreover, LXH254 is a Type 2 ATP -competitive inhibitor of both B-Raf and C-Raf that keeps the kinase pocket in an inactive conformation, thereby reducing the paradoxical activation seen with many B-Raf inhibitors, and blocking mutant RAS-driven signaling and cell proliferation[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Treatment with LXH254 (Compound A) generates tumor regression in several KRAS-mutant models including the NSCLC-derived Calu-6 (KRAS Q61K) and NCI-H358 (KRAS G12C). LXH254 exhibits efficacy in numerous MAPK-driven human cancer cell lines and in xenograft tumors representing model tumors harboring human lesions in KRAS, NRAS and BRAF oncogenes[1].

Animal Administration
[1]

Mice[1]
SCID beige female tumor-bearing NCI-H358 mice, n=8 per group, are randomized into 3 groups 14 days post tumor cell inoculation with an average tumor volume range of 259.44- 262.47mm3. Animals are administered an oral dose of either vehicle, LXH254 at 30mg/kg or 200mg/kg daily for 14 consecutive days at a dosing volume of 10 mL/kg of animal body weight during course of treatment. Tumor volumes are measured by digital caliper 3 times a week and body weights of all animals are recorded through the course of treatment.
Female nude tumor bearing Calu6 mice, n=6 per group are randomized into treatment groups on day 17 following tumor implantation, when the average tumor volume is 180 mm3. Treatments with LXH254 are initiated on Day 17 and continued for 16 days. Dosing volume is 10 mL/kg. Tumor volumes are collected at the time of randomization and twice weekly thereafter for the study duration.
Nude female mice tumor bearing NCI-H358, n=8 per group, are randomized into 2 groups with an average tumor volume range of 275.74 mm3. Animals are administered an oral dose of either vehicle or LXH254 at 100 mg/kg daily for 14 consecutive days at a dosing volume of 10 mL/kg of animal body weight during course of treatment. Tumor volumes are measured by digital caliper 3 times a week and body weights of all animals are recorded through the course of treatment[1].
