Criteria

Inclusion Criteria:

• Patients must have advanced or metastatic NSCLC or cutaneous melanoma

• Presence of KRAS or BRAF mutation (NSCLC) or NRAS mutation (cutaneous melanoma) in tumor tissue

• ECOG (Eastern Cooperative Oncology Group) performance status ≤ 2

Exclusion Criteria:

-Dose expansion - KRAS or NRAS mutant patients groups: Prior treatment with a RAFi (including any BRAFi and pan-RAFi), MEKi and/or ERKi. (Patients with KRAS mutant NSCLC with prior G12C inhibitor treatments are also excluded in the LXH254+trametinib expansion part). BRAF mutant patients group: Prior treatment with any EGFR, ALK, ROS1, KRAS, RAF (both BRAFV600 selective and pan-RAF), MEK1/2 and/or ERK1/2 inhibitors (for patients with BRAF V600 mutant NSCLC, prior treatments with BRAF and MEK1/2 inhibitors are allowed).

Patients who have received more than 3 lines of anti-cancer therapy are excluded.

• History or current evidence of retinal vein occlusion (RVO) or current risk factors for RVO.

• Any medical condition that would, in the investigator's judgment, prevent the patient's participation in the clinical study due to safety concerns or compliance with clinical study procedures.
