About
The purpose of this trial was to explore the clinical utility of two investigational agents in patients with advanced cancer.
This was a multi-center, open-label Phase I/Ib study. The primary objectives of the trial were:
- To characterize the safety and tolerability of intratumoral LHC165 in patients with solid tumors as a single agent and in combination with PDR001
- To determine and evaluate the maximum tolerated dose (MTD)/recommended dose (RD) for LHC165 as a single agent and in combination with PDR001
Full description
This was a multi-center, open-label Phase I/Ib study. The study consisted 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 estimated the Maximum Tolerated Dose (MTD) and/or Recommended Dose for Expansion (RDE) and were planned to test two different dosing schedules for LHC165 single agent (Group A and B) and LHC165 in combination with PDR001 (Group C and D).
The dose expansion parts of the study were planned to use the MTD/RDE for each the LHC165 single agent (Group E) and LHC165 in combination with PDR001 (Group F), 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.
The study was terminated due to business reasons. Groups B, D and E were not opened for enrollment.

Inclusion criteria
- 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.
Exclusion criteria
- 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
- Patients who discontinued prior anti-PD-1/PD-L1 therapy due to an anti-PD-1/PD-L1-related toxicity.
- Malignant disease, other than that being treated in this study
