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.

- 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
Minimum age

Can healthy volunteers participate?
No
Key exclusion criteria
- 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.
