Trial Description

To characterize safety and tolerability and identify a recommended dose and regimen for the
LXH254 in combination with LTT462 or trametinib or ribociclib.

Eligibility Requirements

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

- All patients participating in this clinical trial must have progressed following
standard therapy or, in the opinion of the Investigator, no effective standard therapy
exists, is tolerated, appropriate or is considered equivalent to study treatment.

- 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.

- Patients receiving proton pump inhibitors (PPI) which cannot be discontinued 3 days
prior to the start study treatment and for the duration of the study.

- Patients with Gilbert's syndrome or other heritable diseases of bile processing.
