A Phase I/Ib, Open-label, Multi-center Dose-escalation and Dose-expansion Study of the Safety and Tolerability of Intra-tumorally Administered LHC165 Single Agent and in Combination With PDR001 in Patients With Advanced Malignancies
All compounds are either investigational or being studied for (a) new use(s). Efficacy and safety have not been established. There is no guarantee that they will become commercially available for the use(s) under investigation.
The purpose of this trial is to explore the clinical utility of two investigational agents in patients with advanced cancer.
This is a multi-center, open-label Phase I/Ib study. The study consists of four dose escalation parts and two dose expansion parts testing LHC165 as a single agent or LHC165 in combination with PDR001. The dose escalation parts will estimate the Maximum Tolerated Dose (MTD) and/or Recommended Dose for Expansion (RDE) and test two different dosing schedules for LHC165.
The dose expansion parts of the study will use the MTD/RDE for each the LHC165 single agent and in combination with PDR001, determined in the respective dose escalation parts to assess the activity, safety and tolerability of LHC165 as a single agent or LHC165 in combination with PDR001 in patients with specific types of solid tumors.
Approximately 206 adult patients with advanced solid tumors will be enrolled.

Written informed consent must be obtained prior to any procedures unless considered standard of care.
Adult men and women (≥ 18 years of age) with histologically confirmed diagnosis of metastatic and/or advanced solid tumors not amenable to curative treatment by surgery.
Patients must be willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up.
Dose escalation: Patients with accessible tumors and with measurable disease as determined by RECIST 1.1 and have progressed despite standard treatment or are intolerant of standard treatment, or for whom no standard treatment exists.
Dose expansion: Patients with advanced/metastatic solid tumors: HNSCC, melanoma, accessible tumors and visceral tumors (LHC165 combination with PDR001 only). Patients must have measurable disease as determined by RECIST 1.1 and have progressed despite standard treatment or are intolerant to standard treatment, or for whom no standard treatment exists• Patients must have at least two sites of disease amenable to biopsy.
Patient has an Eastern Cooperative Oncology Group (ECOG) performance status 0-2.
Presence of symptomatic or uncontrolled central nervous system (CNS) metastases requiring local CNS-directed treatment.
Patients diagnosed with hematological malignancies.
Patients with prior stem cell transplants.
Patients previously treated with TLR-7/8 agonist treatment.
History of primary immunodeficiency
