You may qualify if…

To be eligible for study entry patients must satisfy all of the following criteria:
1. Subjects must have the ability to understand and willingness to sign a written informed consent document.
2. Histologically or cytologically confirmed unresectable or metastatic melanoma and pancreatic ductal adenocarcinoma
Cohort 2A: had confirmed progressive disease during treatment with an anti-PD-1/PD-L1 with or without CTLA-4 therapy.
Cohort 2B: had confirmed progressive disease during treatment with first line standard of care chemotherapy per local guideline.
Cohort 2C: must not have received any prior systematic treatment, including chemotherapy, biological therapy, or targeted therapy for unresectable locally advanced/ metastatic pancreatic duct adenocarcinoma.
3. Subject must have at least 1 unidimensional measurable disease by RECIST 1.1.
4. Subjects must be age between 18 years.
5. Subjects must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
6. Life expectancy ≥3 months.
7. Subjects must have adequate organ function

You may not qualify if…

Subjects who meet any of the following criteria cannot be enrolled:
1. Cohort 2A: History of life-threatening toxicity or treatment discontinuation due to related to prior anti-PD-1/PD-L1 with or without CTLA-4 treatment for subjects with unresectable/ metastatic melanoma
2.Subjects have another active invasive malignancy within 5 years, with the following exceptions and notes:
3. Previous exposure to TNFR such as anti-CD137, OX40, CD27 and CD357 antibodies.
4. Subjects must not have received any anticancer therapy or another investigational agent within the shorter of 4 weeks or 5 half-lives before the first dose of the study treatment.
5. Subjects with a history of ≥ Grade 3 immune-related adverse events resulted from previous immunotherapy or treatment discontinuation due to previous immunotherapy. .
6. History of clinically significant sensitivity or allergy to monoclonal antibodies and their excipients or known allergies to antibodies produced from Chinese hamster ovary cells, which in the opinion of the Investigator suggests an increased potential for an adverse hypersensitivity to YH003 or Toripalimab. (For cohort 2C: history of severe hypersensitivity reaction to Nap-paclitaxel and/or gemcitabine).
7. Primary central nervous system (CNS) malignancies or symptomatic CNS metastases.
8. History of (non-infectious) pneumonitis that required corticosteroids or current pneumonitis, or history of interstitial lung disease.
9. Active, hemodynamically significant pulmonary embolism within 12 weeks prior to the first dose of study drug.
10. Subjects must not have a known or suspected history of an autoimmune disorder
11. Clinically uncontrolled intercurrent illness,
12. Severe cardiovascular disease including symptomatic congestive heart failure (New York Heart Association class III or IV), unstable angina, uncontrolled hypertension, cardiac arrhythmia, a history of myocardial infarction within 6 months or a history of arterial thromboembolic event and pulmonary embolism within 3 months of the first dose of investigational agent.
13. QTc > 480 ms (Fridericia equation) at baseline; no concomitant medications that would prolong the QT interval; no family history of long QT syndrome.
