CAN-2409 Plus Prodrug With Standard of Care Immune Checkpoint Inhibitor for Stage III/IV NSCLC Patients
The purpose of this clinical trial is to evaluate the effects of adding CAN-2409 + prodrug for stage III/IV NSCLC patients who are on standard of care first line immune checkpoint inhibitors (ICI) treatment with evidence that the clinical response is inadequate. CAN-2409 is an oncolytic viral immunotherapy that induces tumor-infiltrating T-cells and a consequent PD-L1 up-regulation. A combination of CAN-2409 added to standard of care (SOC) checkpoint inhibitors may lead to improved long-term outcomes for patients with NSCLC who have suboptimal response to ICI therapy.
Cohort 1 is for patients with stable disease radiographically at least 18 weeks after starting ICI treatment and are clinically stable.
Cohort 2 is for patients with evidence of radiographic progression at least 18 weeks after starting ICI treatment but who are clinically stable.
Cohort 3, which is now closed for enrollment, was for patients who had evidence of radiographic progression at least 9 weeks after starting ICI but who were clinically stable.
The specific ICI treatment regimen is not specified to allow for different standard of care options with or without chemotherapy; for example, pembrolizumab alone, pembrolizumab plus chemotherapy, or atezolizumab/chemotherapy. In addition, it allows stage III patients after chemoradiation who may be on durvalumab as their standard of care. For example, a stage III patient may be eligible for cohort 2 if they have radiographic progression but are clinically stable 18 weeks after starting durvalumab.
The release of Version 05 of the protocol increased enrollment numbers into Cohorts 1 and 2 (from target n=32 evaluable to n=40 evaluable), while closing Cohort 3. Adjustments to the sample size extended the anticipated primary completion date for this trial.

Accepting Healthy Volunteers?
No
1. Patients with Stage III/IV NSCLC on first line treatment with anti-PD-1/PD-L1 (ICI) +/- chemotherapy for their current stage of disease and fits into one of the following cohorts as determined by investigator, preferably as per RECIST 1.1: Cohort 1) have persistent but stable disease at least 18 weeks after starting ICI treatment, or Cohort 2) have radiographic progressive disease at least 18 weeks after starting ICI treatment
2. RECIST evaluable disease including a lesion that is amenable to injection
3. Able and willing to undergo a pre-treatment and on-treatment biopsies, if feasible
4. ECOG Performance status of 0 or 1
5. 18 years of age or older
6. Granulocyte count (ANC) ≥ 1,000/mm3
7. Hemoglobin ≥ 8 g/dl (patients may be transfused to meet this criterion)
8. Platelets ≥ 75,000/mm3
9. Total bilirubin ≤ 1.5 x upper limit of normal, except for patients with known Gilbert disease who must have total bilirubin ≤ 3 x upper limit of normal
10. SGOT (AST) ≤ 5x upper limit of normal and if elevated, not clinically significant such that ICI can continue
11. INR no more than 0.2 above upper limit of normal and aPTT not >1.2 x upper limit of normal, and value is acceptable for patient to undergo injection procedure. If on anti-coagulation, it must be clinically acceptable to hold anti-coagulation for the injection procedures per investigator discretion

Exclusion Criteria:
1. Patients with a history of severe hypersensitivity reaction to ICI
2. Patients who require ongoing therapy with disease-modifying antirheumatic drugs (DMARDs), immunomodulators or systemic immunosuppressive drugs including systemic corticosteroids (>10 mg prednisone per day or equivalent) - premedication for ICI or chemotherapy is allowed
3. Patients with a history of active autoimmune disease requiring treatment in the past 2 years
4. Patients with uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, active hepatitis, or psychiatric illness/social situations that would limit compliance with study requirements
5. Women who are pregnant, lactating or intend to become pregnant during the study
6. Patients who are known to be HIV positive
7. Patients with a history of hypersensitivity or allergic reactions to valacyclovir or acyclovir
8. Patients with significant heart disease (New York Heart Association Functional Classification III or IV)
9. Patients with continuous oxygen dependence >2L/min at rest
10. Tumor impinging on a neurovascular structure such that inflammation in the site may put patient at risk of compromise as determined by the investigator
11. Patients with uncontrolled brain metastases as per investigator
12. Patients with liver metastases involving more than half of the liver
13. Patients with known EGFR mutation, ALK fusion, or ROS1 fusion positive NSCLC, or that are receiving tyrosine kinase inhibitor (TKI) agents/ALK/ROS1 inhibitors
14. Patients with known interstitial lung diseases (ILDs) requiring active therapy (Radiographic fibrosis not requiring therapy is allowed)
15. Patients receiving vascular endothelial growth factor (VEGF) inhibitors (including bevacizumab, ramucirumab) within the past 2 months or five half-lives, whichever is longer
