• Receipt of anticancer medications or investigational drugs within the following

intervals before the first administration of study drug:

1. = 14 days for chemotherapy, targeted small molecule therapy, or radiation therapy. Subjects must also not require chronic use of corticosteroids and must not have had radiation pneumonitis because of a treatment. A 1-week washout is permitted for palliative radiation to non-central nervous system (CNS) disease with medical monitor approval. Note: Bisphosphonates and denosumab are permitted medications.

2. = 28 days for prior immunotherapy or persistence of active cellular therapy (e.g., chimeric antigen receptor T cell therapy; other cellular therapies must be discussed with the medical monitor to determine eligibility).

3. = 28 days for a prior monoclonal antibody used for anticancer therapy except for denosumab.

4. = 7 days for immune-suppressive-based treatment for any reason. Note: Use of inhaled or topical steroids or corticosteroid use for radiographic procedures is permitted. Note: The use of corticosteroids equivalent to prednisone </= 10mg/day is allowed.

5. = 28 days or 5 half-lives (whichever is longer) before the first dose for all other investigational study drugs or devices.

6. = 14 days for COVID-19 vaccine.

• Has not recovered to = Grade 1 from toxic effects of prior therapy (including prior immunotherapy) and/or complications from prior surgical intervention before starting therapy.
• Receipt of a live vaccine within 30 days of planned start of study therapy.
• Active autoimmune disease that required systemic treatment in the past (i.e., with use of disease-modifying agents, corticosteroids, or immunosuppressive drugs).
• Known active CNS metastases and/or carcinomatous meningitis.
• Known additional malignancy that is progressing or requires active treatment, or history of other malignancy within 2 years of study entry after treatment with curative intent.
• Has a history of (non-infectious) pneumonitis / interstitial lung disease that required steroids or has current pneumonitis / interstitial lung disease.
• Documented known activating or driver mutations (i.e. EGFR mutations/amplification, BRAF mutations, ALK alterations, etc.) which have not been previously treated with a standard of care targeted therapy.
• Subjects with screening QTc interval >470 milliseconds are excluded.
• Uncontrolled systemic fungal, bacterial, viral, or other infection despite appropriate anti-infection treatment.
• Evidence of hepatitis B virus (HBV) or hepatitis C virus (HCV), unless the hepatitis is considered to be cured.
• Known history of HIV (HIV 1 or HIV 2 antibodies).
• Known allergy or reaction to any component of study drug or formulation components.
• Is pregnant or breastfeeding or expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 90 days after the last dose of study treatment.
• Any condition that would, in the investigator's judgment, interfere with full participation in the study, including administration of study drug and attending required study visits; pose a significant risk to the subject; or interfere with interpretation of study data.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Treatment-emergent Adverse Events as Assessed by CTCAE v5.0	The number of participants who have had at least one TEAE during the study.	From enrollment through up to 90 days after end of treatment, an average of 1 year
Secondary	Objective Response Rate (ORR) as Assessed by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1	To assess antitumor activity/efficacy by evaluating objective response rate (ORR), defined as the percentage of participants who experienced a complete response (CR; disappearance of all target lesions) or a partial response (PR; at least a 30% decrease in the sum of diameters of target lesions) based on Response Evaluation Criteria in Solid Tumors (RECIST) v1.1	Approximately 1 year
Secondary	Duration of Response (DoR) as Assessed by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1	To assess antitumor activity/efficacy by evaluating duration of response (DoR), defined as the time from the first documented complete response or partial response per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 to the first documented progressive disease or death due to any cause, whichever occurs first. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions and assessed by CT or MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions.	Approximately 1 year
Secondary	Disease Control Rate (DCR) as Assessed by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1	To assess antitumor activity/efficacy by evaluating disease control rate (DCR), defined as the proportion of participants in whom a documented complete response, partial response, or stable disease is observed as the best overall response per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.	Approximately 1 year
Secondary	Progression-free Survival (PFS) Per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1	To evaluate progression-free survival (PFS), defined as the time from the first dose of NC318 to the first occurrence of documented progressive disease or death due to any cause, whichever occurs first. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.
