Brief Summary:
This phase I trial is designed as an open-label, dose escalation trial of MEM-288 monotherapy in which investigators aim to find the maximum tolerated dose (MTD) and recommended phase II dose (RP2D). Subjects with selected solid tumors including non-small cell lung cancer (NSCLC) who have a tumor lesion which is accessible for injection will undergo intratumoral injection of MEM-288. The study rationale is that the oncolytic effect of MEM-288 combined with the presence of CD40L and type 1 interferon (IFN) in injected tumors will provide a strong signal for dendritic cell (DC)-mediated T cell activation leading to generation of systemic anti-tumor T cell responses with broad specificity akin to what is observed in the abscopal effect.

Detailed Description:

MEM-288 is a conditionally replicative oncolytic adenovirus vector encoding transgenes for human interferon beta (IFNβ) and a recombinant chimeric form of CD40-ligand (MEM40). MEM-288 was developed as an immunotherapy for cancer and was engineered to selectively replicate in cancer cells leading to cancer cell lysis but not cytotoxicity towards normal cells. Simultaneously, MEM-288 is designed to stimulate an anti-tumor immune response through expression of its encoded immune agonist transgenes. MEM-288 is designed to provide both antitumor activity as a standalone monotherapy and in combination with immune checkpoint inhibitor(s) to enhance the efficacy of immune checkpoint inhibition in solid tumors.

This phase I trial is an open-label, dose escalation trial of MEM-288 monotherapy in which investigators aim to find the MTD and recommended phase II dose for the planned combination of MEM-288 with an immune checkpoint inhibitor. Patients (≥ 18 years old) eligible for study enrollment include those with either advanced/metastatic NSCLC, cutaneous squamous-cell carcinoma (cSCC), Merkel cell, melanoma, triple negative breast cancer (TNBC), pancreatic cancer, or head and neck cancer, who progressed following previous anti-PD-1/PD-L1 therapy, with a tumor lesion which is accessible for injection.

MEM-288 will be administered via intratumoral injection once every 3 weeks (planned 2 doses, maximum 6 doses) at an assigned dose cohort level (from 1x10^10 to 1x10^11 viral particles).

The primary study objective is to determine the safety, tolerability, and maximum tolerated dose (MTD) of intratumoral administration of MEM-288 as a single agent. Secondary objectives will assess efficacy overall response rate, as well as disease control rate, progression free survival, duration of response, and anti-tumor immune responses.

Primary Outcome Measures :
  1. Maximum Tolerated Dose (MTD) [ Time Frame: 21 days ]
    MTD is defined as the highest dose with ≤ 17% dose limiting toxicity (DLT) rate.

  2. Safety and Tolerability assessed by Adverse Events (AEs) [ Time Frame: 4.5 months ]
    An adverse event (AE) is any untoward medical occurrence in a subject receiving study drug and which does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended or worsening sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a study drug, whether or not related to use of the study drug.


Secondary Outcome Measures :
  1. Overall Response Rate (ORR) [ Time Frame: up to 39 weeks ]
    ORR measured by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.

  2. Disease Control Rate (DCR) [ Time Frame: up to 39 weeks ]
    DCR measured by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.

  3. Duration of Response (DoR) [ Time Frame: up to 39 weeks ]
    DoR measured by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.

  4. Progression Free Survival (PFS) [ Time Frame: up to 39 weeks ]
    To determine the PFS days post treatment initiation.

  5. Overall Survival (OS) [ Time Frame: up to 39 weeks ]
    To determine the survival days post treatment initiation.


Other Outcome Measures:
  1. Exploratory Biomarker Analysis [ Time Frame: 4.5 months ]
    Analysis of potential associations between biomarker measures and anti-tumor activity, immunogenicity, and immune-activation assessments.
