Clinical Trial Summary

CMN-001 is an autologous, tumor antigen-loaded dendritic cell immunotherapy. The active components of CMN-001 are autologous, matured dendritic cells, which have been co-electroporated with both in vitro transcribed (IVT) RNA from an autologous tumor specimen and CD40L RNA. CMN-001 is indicated for treatment of intermediate/poor risk patients with advanced renal cell carcinoma (RCC) in combination with nivolumab plus ipilimumab as first line therapy and in combination with lenvatinib plus everolimus as 2nd line therapy post 1st line failure.

15. Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures

16. Signed and dated informed consent document indicating that the subject (or legally acceptable representative) has been informed of all pertinent aspects of the trial prior to enrollment

Exclusion Criteria:

1. Prior history of malignancy within the preceding 3 years, except for adequately treated in situ carcinomas or non-melanoma skin cancer, adequately treated early stage breast cancer, superficial bladder cancer, and non-metastatic prostate cancer with a normal PSA.

2. History of or known brain metastases, spinal cord compression, or carcinomatous meningitis, or evidence of brain or leptomeningeal disease

3. Patients will be excluded if they have <2 of the following risk factors at Screening:

1. Time from diagnosis to systemic treatment < 1 year

2. Hgb < LLN

3. Corrected calcium > 10.0 mg/dL

4. KPS < 80%

5. Neutrophils > ULN

6. Platelets > ULN

4. NCI CTCAE Grade 3 hemorrhage < 28 days before Visit 1 (Week 0)

5. Clinically significant cardiovascular conditions within 3 months prior to Randomization, which in the Investigator's opinion prohibits the initiation of

standard targeted therapy, initiating with sunitinib, including:

1. Cardiac angioplasty

2. Myocardial infarction

3. Unstable angina

4. Coronary artery by-pass graft or stenting

5. Class III or IV congestive heart failure (CHF), per NYHA Classification NOTE:

Patients with left ventricular ejection fraction (LVEF) < LLN as assessed by either echocardiography or multiple gated acquisition (MUGA) scan, who are asymptomatic and are NOT classified as having NYHA Class III or IV CHF, may be eligible but should be monitored for LVEF changes while on sunitinib therapy as recommended in the current sunitinib prescribing information.

6. Symptomatic peripheral vascular disease

7. Cerebrovascular accident (CVA) or transient ischemic attack (TIA)

8. Symptomatic or uncontrolled pulmonary embolism or deep vein thrombosis (DVT)

9. Uncontrolled cardiac dysrhythmias of NCI CTCAE Grade = 2, or prolongation of the QTc for males > 450 msec and for females > 470 msec as corrected by either the Fridericia or Bazett formula

10. Uncontrolled or untreated atrial fibrillation

11. Poorly controlled hypertension, defined as a systolic blood pressure (SBP), = 150 mm Hg or diastolic blood pressure (DBP) = 90 mm Hg NOTE: Initiation of antihypertensive medication(s) is permitted prior to study entry. Blood pressure must be re-assessed on 2 occasions separated by at least 1 hour. Mean SBP/DBP values must be less than 150/90 for eligibility.

12. Evidence of active bleeding or a bleeding diathesis at Screening

6. Significant gastrointestinal abnormalities:

1. Any history of major resection of the stomach or small bowel with ongoing impaired healing.

2. Malabsorption syndrome with active symptoms in the Investigator's opinion, within 3 months prior to Randomization

3. Active peptic ulcer, which cannot be appropriately managed in the Investigator's opinion, within 3 months prior to Randomization

4. Intra-luminal bleeding lesions within 3 months prior to Randomization

5. History of abdominal fistula or intra-abdominal abscess within 3 months prior to Randomization

7. Pre-existing thyroid abnormality with thyroid function that cannot be appropriately managed with medication, in the Investigator's opinion.

8. Active autoimmune disease or condition requiring chronic immunosuppressive therapy, such as rheumatoid arthritis, systemic lupus erythematous, multiple sclerosis, organ transplant recipient, etc. NOTE: Abnormal laboratory values for autoimmunity markers in the absence of other signs/symptoms of autoimmune disease are not exclusionary.

9. Clinically significant infections, including human immunodeficiency virus (HIV), syphilis, and active hepatitis B or C

10. Current treatment with an investigational therapy on another clinical trial

11. Pregnancy or breastfeeding

12. Any serious medical condition or illness considered by the investigator to constitute an unwarranted high risk for investigational treatment
