Eligibility Criteria
Inclusion
- Subjects must have the ability to understand and willingness to sign a written informed consent document.
- Part I dose escalation:
- Have histologically advanced or cytologically confirmed solid tumor. Have progressed on after treatment with at least one standard therapy or intolerant of the standard therapy.
- Part II dose expansion:
- Cohort 2A: Histologically or cytologically confirmed unresectable or metastatic melanoma that had confirmed progressive disease during treatment with an anti-PD-1/PD-L1 therapy with or without additional CTLA-4 therapy. Subjects with BRAF activating mutation could have also received a BRAF inhibitor and/or MEK inhibitor regimen prior to anti-PD-1/PD-L1 therapy.
- Cohort 2B, 2C: Subject has histologically or cytologically documented diagnosis of pancreatic ductal adenocarcinoma with unresectable locally advanced/metastatic disease Cohort 2B: had confirmed progressive disease during treatment with first line standard of care of chemotherapy per local standard.
- Cohort 2C: treatment-naïve for unresectable locally advanced/metastatic disease.
- Subject must have measurable disease by RECIST 1.1. At least 1 unidimensional measurable target lesion per RECIST v1.1 for study Part II expansion cohorts.
- Subjects must be age 18 years or older.
- Subjects must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. Life expectancy ≥3 months.
- Subjects must have adequate organ function.
- Women of reproductive potential must have negative serum beta human chorionic gonadotropin (β -HCG) pregnancy test.
Exclusion
- Part II Cohort 2A: History of life-threatening toxicity or treatment discontinuation due to related to prior anti-PD-1/PD-L1 and with or without CTLA-4 combination treatment for subjects with unresectable/metastatic melanoma.
- Subjects must not have another active invasive malignancy.
- Previous exposure to TNFR such as anti-CD137, OX40, CD27 and CD357 antibodies.
- 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.
- Subjects with a history of ≥ Grade 3 immune-related adverse events resulted from previous immunotherapy.
- 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. Also history of severe hypersensitivity reaction to Nap-paclitaxel and/or gemcitabine.
- Primary central nervous system (CNS) malignancies or symptomatic CNS metastases.
- History of (non-infectious) pneumonitis that required corticosteroids or current pneumonitis, or history of interstitial lung disease.
- Subjects must not have a known or suspected history of an autoimmune disorder, including but not limited to inflammatory bowel disease, celiac disease, Wegner syndrome, Hashimoto syndrome, systemic lupus erythematosus, scleroderma, sarcoidosis, or autoimmune hepatitis, within 3 years of the first dose of study treatment.
- Clinically uncontrolled intercurrent illness, including an ongoing or active infection, active coagulopathy, uncontrolled diabetes, psychiatric illness that would limit compliance with the study requirements and other serious medical illnesses requiring systemic therapies.
- 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.
- QTc \> 450 ms at baseline; no concomitant medications that would prolong the QT interval; no family history of long QT syndrome.
- Subjects must not have active infection of human immunodeficiency virus (HIV), hepatitis B, or hepatitis C.
- Subjects must not have a history of primary immunodeficiency.
- Subjects from endemic area will be specifically screened for tuberculosis. Subjects with active tuberculosis are excluded.
- Subjects must not receive concurrent or prior use of an immunosuppressive agent within 4 weeks of the first dose of YH003.
- Major surgery within 4 weeks prior to study entry and Minor surgery within 2 weeks prior to the first dose of YH003.
- Subjects must not have received a live attenuated vaccine within 28 days before the first dose of YH003, and subjects, if enrolled, should not receive live vaccines during the study or for 180 days after the last dose of YH003.
