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 inhibitor (ICI) treatment with evidence that the clinical response is inadequate. CAN-2409 is a viral immunotherapy approach 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.
This clinical trial evaluates the addition of CAN-2409 plus prodrug for stage III/IV
NSCLC patients who are on standard of care first line ICI (anti-PD-1/PD-L1) but with
evidence of suboptimal response (either disease progression or stable disease at time of
study enrollment). CAN-2409 plus prodrug has been shown to increase the response rate to
ICI in animal studies. Safety and tolerability of CAN-2409 plus prodrug has been
demonstrated in clinical trials in over 950 patients with cancer, including cancers of
the lung, pancreas, prostate, and brain. Initial proof of mechanism has been shown in
non-small lung cancer, prostate cancer, high-grade glioma, and pancreatic cancer. The
eligibility criterion in the current clinical trial is based on time on ICI and response
status with cohorts as follows:
Cohort 1A and 1B: patients with stable disease radiographically at least 18 weeks after
starting ICI treatment and who are clinically stable
Cohort 2A and 2B: 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. In Amendment 6,
cohort 1B and 2B were initiated to evaluate a 3-dose regimen of CAN-2409 + prodrug.
Adjustments to the sample size extended the anticipated primary completion date for this
trial.

Inclusion Criteria:
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:

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

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

more than 4 weeks of current ICI
15. Patients should not have received focal therapy (e.g., radiotherapy) at more than
three different sites of disease within 12-months prior to enrollment
16. Patients must give study specific informed consent prior to enrollment and any study
specific procedures
Exclusion Criteria:
1. Patients with a history of severe immune related adverse events related 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

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
