Phase II, Multi-center, Open-label Study of Single-agent LGX818 Followed by a Rational Combination With Agents After Progression on LGX818, in Adult Patients With Locally Advanced or Metastatic BRAF V600 Melanoma

The primary purpose of the Phase II CLGX818X2102 study is to assess the anti-tumor activity
of LGX818 in combination with selected agents.

This is a phase II two part multi-center, open-label study. Part I: LGX818 single agent
treatment until progression Part II: Combination treatments of LGX818 + MEK162, or BKM120,
or BGJ398, or INC280, or LEE01 to assess the clinical efficacy, to further evaluate the
safety of the drug combinations in patients with locally advanced or metastatic BRAF mutant
melanoma after relapse on LGX818, and to determine the maximum tolerated dose of the
combinations (when not established previously). These drug combinations are selected and
assigned to patients based on documentation of molecular resistance mechanism.

Patients with BRAF mutant melanoma treated by LGX818 single agent in other studies can be
enrolled directly in Part II of CLGX818X2102 after relapse.

Dose-escalations in the combination arms for which no MTD has been established will be based
on the recommendations of a Bayesian logistic regression model guided by an escalation with
overdose control criterion

Inclusion Criteria:

- locally advanced or metastatic melanoma

- confirmed BRAF V600 mutation

- patients naïve to a selective BRAF inhibitor

- fresh tumor biopsy at baseline, and patient agrees for a mandatory biopsy at the time
of relapse

- World Health Organization (WHO) Performance Status ≤ 2.

Exclusion Criteria:

- Previous treatment with RAF-inhibitor

- Symptomatic or untreated leptomeningeal disease

- Symptomatic brain metastases.

- Known acute or chronic pancreatitis

- Clinically significant cardiac disease

- AST/SGOT and ALT/SGPT > 2.5 x ULN, or > 5 x ULN if liver metastases are present

- Impairment of gastrointestinal (GI) function or GI disease that may significantly
alter the absorption of oral interventional drug

- Previous or concurrent malignancy.

- Other severe, acute, or chronic medical or psychiatric condition or laboratory
abnormality that may increase the risk associated with study participation
