This study is a single-arm, open-label, phase I/II trial designed to find a CMP-001 dose
that, in combination with pembrolizumab, has optimal clinical efficacy and acceptable
toxicity for patients with relapsed and refractory lymphomas.
This is a single center, open-label, combined Phase I/II clinical study of intratumoral
administration of CMP-001 and intravenous administration of pembrolizumab in selected
participants with lymphoma. The key study objective is to find a CMP-001 dose that in
combination with pembrolizumab has optimal clinical efficacy and acceptable toxicity.
Dose-finding will be performed with an adaptive clinical trial design. Secondary study
objectives include characterization of safety, pharmacodynamics, and assessment of

Participants are excluded from the study if any of the following criteria apply:
- A WOCBP who has a positive urine pregnancy test within 72 hours prior to first dose of
study drug. (see Appendix C). If the urine test is positive or cannot be confirmed as
negative, a serum pregnancy test will be required.

- Has received prior systemic anti-cancer therapy including investigational agents
within 2 weeks or 5 half-lives whichever is shorter, prior to first dose of study
Note: Participants must have recovered from all AEs due to previous therapies to ≤Grade 1
or baseline. Participants with </= Grade 2 neuropathy may be eligible.
Note: If participant received major surgery, they must have recovered adequately from the
toxicity and/or complications from the intervention prior to starting study treatment.
- Has received prior radiotherapy within 2 weeks of start of study treatment.
Participants must have recovered from all radiation-related toxicities, not require
corticosteroids, and not have had radiation pneumonitis. A 1-week washout is permitted
for palliative radiation (</= 2 weeks of radiotherapy) to non-CNS disease.
- Has received a live vaccine within 30 days prior to the first dose of study drug.
Examples of live vaccines include, but are not limited to, the following: measles,
mumps, rubella, yellow fever, rabies, Bacillus Calmette-Guérin (BCG), and typhoid
vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines
and are allowed; however, intranasal influenza vaccines (eg, FluMist®) are live
attenuated vaccines and are not allowed.
- Is currently participating in or has participated in a study of an investigational
agent or has used an investigational device within 4 weeks or within 5 half-lives
whichever is shorter, prior to the first dose of study treatment.
Note: Participants who have entered the follow-up phase of an investigational study may
participate as long as it has been 2 weeks or within 5 half-lives whichever is shorter,
after the last dose of the previous investigational agent.
- Has a diagnosis of primary immunodeficiency disorder or is receiving chronic systemic
steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any
other form of immunosuppressive therapy within 7 days prior to the first dose of study
- Has a known additional malignancy that is progressing or has required active treatment
within the past 3 years. Note: Participants with basal cell carcinoma of the skin,
squamous cell carcinoma of the skin, or carcinoma in situ (e.g. breast carcinoma,
cervical cancer in situ) that have undergone potentially curative therapy are not
- Has known active CNS metastases and/or carcinomatous meningitis. Participants with
previously treated brain metastases may participate provided they are radiologically
stable, i.e. without evidence of progression for at least 4 weeks by repeat imaging
(note that the repeat imaging should be performed during study screening), clinically
stable and without requirement of steroid treatment for at least 14 days prior to
first dose of study treatment.

(i.e. with use of disease modifying agents, corticosteroids or immunosuppressive
drugs). Replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid
replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a
form of systemic treatment.
- Has a history of (non-infectious) pneumonitis that required steroids or has current
- Has an active infection requiring systemic therapy.
- Has a known history of Human Immunodeficiency Virus (HIV). Note: No HIV testing is
required unless mandated by local health authority.
