Clinical Trial of VBC103 in Patients With Advanced Malignant Solid Tumors

Summary

This study is a multicenter, open-label, multi-dose, first-in-human (FIH) Phase I/IIa study to determine the safety and tolerability of VBC103, as well as the maximum tolerated dose (MTD) and/or recommended Phase II dose (RP2D), PK and further evaluate its efficacy.

* 3.At least one measurable lesion as assessed by the investigator per RECIST v1.1.
* 4.Adult male or female (defined as ≥18 years of age)

* 6.LVEF ≥50% as measured by ECHO or MUGA within 28 days prior to enrollment.
* 7.Life expectancy exceeding 12 weeks.
* 8.Availability of archived tumor tissue samples or willingness to undergo biopsy sampling.

Exclusion Criteria:

* 1.Any unresolved ≥Grade 2 toxicity from prior anticancer therapy.
* 2.Known active keratitis or corneal ulcer.
* 3.History of interstitial lung disease (e.g., non-infectious interstitial pneumonia, pneumonitis,pulmonary fibrosis, or severe radiation pneumonitis), current interstitial lung disease, or suspected interstitial lung disease based on imaging during the screening period.
* 4.History of underlying pulmonary diseases, including but not limited to pulmonary embolism within 3 months prior to the start of investigational product, severe asthma, severe chronic obstructive pulmonary disease, restrictive lung disease, and other clinically significant pulmonary impairment or requiring supplemental oxygen, as well as any autoimmune, connective tissue, or inflammatory disease involving the lungs (such as rheumatoid arthritis, Sjögren's syndrome, sarcoidosis, etc.) and/or prior pneumonectomy (complete resection).
