Oncolytic Virotherapy Plus PD-1 Inhibitor and Lenvatinib for Patients with Advanced Pancreatic Cancer

A Phase 1b Dose-escalation and Cohort-expansion Study of the Safety/tolerability, and Efficacy of Oncolytic Virotherapy Plus PD-1 Inhibitor and Lenvatinib for Patients with Advanced Pancreatic Cancer

The objective of this study is to evaluate the safety/tolerability efficacy of oncolytic virotherapy combined with Tislelizumab plus lenvatinib for advanced pancreatic cancer patients who were relapsed or refractory to standard therapy

Study Overview

• Status: Completed
• Conditions: Pancreatic Ductal Adenocarcinoma
• Intervention / Treatment: Drug: H101; Drug: Tislelizumab; Drug: lenvatinib

Detailed Description

Recent studies have suggested that local destruction of tumor tissue by oncolytic virus induced activation and maturation of dendritic cells and tumor-specific T cells by cross-presentation of tumor antigens. While pd-1 blocking antibody interferes with PD-1 mediated T-cell regulatory signaling. And combination of pd-1 blocking antibody plus lenvatinib showed increased ORR in many types of human cancers. Therefore, the objective of this study is to evaluate the safety and efficacy of oncolytic virotherapy combined with Tislelizumab plus lenvatinib for advanced pancreatic cancer patients who were relapsed or refractory to standard therapy.

• Any condition or comorbidity that, in the opinion of the investigator, would interfere with evaluation of study Treatment or interpretation of patient safety or study results, including but not limited to:

  1. history of interstitial lung disease
  2. Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) coinfection (i.e double infection)

  8. Has an active autoimmune disease requiring systemic treatment within the past 3 months or a documented history of clinically severe autoimmune disease, or a syndrome that requires systemic steroids or immunosuppressive agents. Exceptions: Subjects with vitiligo, hypothyroidism, diabetes mellitus type I or resolved childhood asthma/atopy are an exception to this rule. Subjects that require intermittent use of bronchodilators or local steroid injections would not be excluded from the study. Subjects with Hashimoto thyroiditis, hypothyroidism stable on hormone replacement or psoriasis not requiring treatment are not excluded from the study.

Participant Group / Arm

Intervention / Treatment

Experimental: H101 + Tislelizumab+ Lenvatinib; (Dose escalation and cohort expansion) H101 administered by intratumoral injection in combination with Tislelizumab administered intravenously (IV), and Lenvatinib administered orally.
