antibody, when administered either alone or in combination with PD-1 inhibition prior to surgical resection.\n\nThe investigator hypothesizes that preoperative administration of CD40 agonist with or without PD-1 inhibitor intratumorally will demonstrate an acceptable safety profile, will not result in an unplanned delay in surgery, and will lead to increased immune activation.\n\nSubjects will receive a single intratumoral dose of CD40 agonist with or without PD-1 inhibitor 7 or more days prior to surgery and will be followed for safety, feasibility, immune, and pathologic responses.'},

Female patients of childbearing potential who are not abstinent and intend to be sexually active with a non-sterilized male partner must use at least 1 highly effective method of contraception from the time of screening throughout the total duration of the drug treatment and the drug washout period (90 days after therapy). Non-sterilized male partners of a female patient of childbearing potential must use male condom plus spermicide throughout this period. Female patients should also refrain from breastfeeding throughout this period.\n14. Able and willing to comply with all study procedures.\n\nExclusion Criteria:\n\n1. Metastatic disease.\n2. Planned neoadjuvant therapy, i.e., not undergoing upfront surgery.\n3. Known history of hepatitis B or C with active viral replication.\n4. Administration of any live vaccine within 28 days of first dose of study treatment.\n5. Prior CD40 or anti-PD-1 agonist therapy.\n6. Participation in another interventional clinical trial within 30 days before receiving first dose of study treatment. However, the subject may participate in observational studies.\n7. Any illness or condition that in the opinion of the investigator may affect the safety of the subject or the evaluation of any study endpoint.\n8. Current or prior use of immunosuppressive medication within 14 days before study treatment. The following are exceptions to this criterion:\n\n 1. Intranasal, inhaled, topical steroids, or local steroid injections (e.g., intra articular injection)\n 2. Systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisone or its equivalent\n9. Major surgical procedure (as defined by the Investigator) within 28 days prior to the first dose of IP.\n10. History of allogenic organ transplantation\n11. Active or prior documented autoimmune disease. Examples include inflammatory bowel disease \\[e.g., colitis or Crohn's disease\\], systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome \\[granulomatosis with polyangiitis\\], Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc.\\].

Patients without active autoimmune disease in the last 5 years may be included but only after consultation with the study physician\n 5. Patients with celiac disease controlled by diet alone\n12. Uncontrolled intercurrent illness, including but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease, serious chronic gastrointestinal conditions associated with diarrhea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs or compromise the ability of the patient to give written informed consent\n13. History of another active malignancy except for non-melanoma skin cancer, lentigo maligna or other carcinoma in situ\n14. History of active primary immunodeficiency\n15. Known allergy or hypersensitivity to any of the study drugs or any of the study drug excipients.\n16. Body weight \\> 110 kg.\n17.
