1. Adequately treated basal cell or squamous cell carcinoma

2. In situ carcinoma of the cervix or bladder, treated curatively and without
evidence of recurrence for at least 2 years prior to the study, or

3. A primary malignancy which has been completely resected and in complete remission
for at least 2 years

11. History of (noninfectious) pneumonitis/interstitial lung disease that required
steroids or has current pneumonitis/interstitial lung disease.

12. Prior grade > 3 immune-related AEs such as pneumonitis, colitis, hepatitis, nephritis;

longer required and endocrine-replacement therapy is stable and discontinued from
prior therapy.

13. Active autoimmune disease not related to prior therapy for primary malignancy that has
required systemic therapy in the last 1 year.

14. History of symptomatic congestive heart failure (New York Heart Association classes
II-IV) or serious active arrhythmias or other clinically significant cardiac disease
within 12 months of enrollment.

15. Toxicity from previous anti-cancer therapy defined as toxicities (other than alopecia,
or laboratory values listed above) not yet resolved to NCI CTCAE v5.0 Grade = 1 or
baseline. Participants with chronic Grade 2 toxicities (eg, peripheral neuropathy,
laboratory values) may be eligible per the discretion of the Investigator and Medical
Monitor.

16. Has received:

1. Radiotherapy within 2 weeks of first administration of MT-302

2. Cytotoxic chemotherapy for treatment of the primary malignancy within 28 days or
5 half-lives, whichever is shorter, of administration of MT-302

3. Immune therapy for primary malignancy (eg, monoclonal antibody therapy,
checkpoint inhibitors) within 28 days or 5 half-lives, whichever is shorter of
first administration of MT-302

4. Targeted therapies for primary malignancy within 28 days or 5 half-lives,
whichever is shorter, of first administration of MT-302

5. Anti-cancer vaccine within 12 weeks of first administration of MT-302

6. COVID-19 mRNA vaccine within 6 weeks of first administration of MT-302

18. Has received packed red blood cells or platelet transfusion within 2 weeks prior to
first administration of MT-302

20. Enrollment in another interventional clinical trial within 28 days or 5 half-lives of
the drug, whichever is shorter, of first administration of MT-302

21. Any other condition that, in the opinion of the Investigator, would make the
participant unsuitable for the study or unable to comply with the study requirements.
