A Study of LGK974 in Patients With Malignancies Dependent on Wnt Ligands

Inclusion Criteria: Diagnosis of locally advanced or metastatic cancer that has progressed despite standard therapy or for which no effective standard therapy exists and histological confirmation of one of the following diseases indicated below: Single Agent Dose escalation part:documented B-RAF mutant colorectal cancer or pancreatic adenocarcinoma. In addition, tumors of any histological origin with documented genetic alterations upstream in the Wnt signaling pathway are eligible with prior agreement with Novartis. Single Agent Dose expansion part: documented B-RAF mutant colorectal cancer with documented RNF43 mutation and/or RSPO fusion or pancreatic adenocarcinoma with documented RNF43 mutation. In addition, patients with tumors of any histological origin with documented genetic alterations upstream in the Wnt signaling pathway (e.g. RNF43 or RSPO fusion) are eligible with prior agreement with Novartis LGK974 with PDR001: Dose escalation: patients with the following cancers that were previously treated with anti-PD-1 therapy and whose best response on that therapy was progressive disease (i.e. primary refractory): melanoma, lung SCC, HNSCC. Patients with esophageal SCC, cervical SCC or TNBC who are either naïve or primary refractory to prior anti-PD-1 therapy. LGK974 with PDR001: Dose expansion: patients with: * cutaneous melanoma that was primary refractory to prior anti-PD-1 therapy, defined as a best response of progressive disease or stable disease for \<= 4 mon…
