A Study of SKB518 in Patients With Advanced Solid Tumors
- Summary
- This is a first-in-human (FIH), phase 1, multicenter, open-label, dose-escalation study of SKB518 to evaluate the safety, tolerability, PK, immunogenicity, and antitumor activity in adult subjects with advanced or metastatic solid tumor relapsed/refractory to standard therapies or for which no effective standard therapy is available.

Number of subjects achieving Dose-limiting toxicity (DLT)
Timeframe: From data of initial dose until up to 21 days for treatment
DLT is defined as an adverse event (AE) that meets protocol defined DLT criteria during cycle 1 and is at least possibly related to study drug.
Maximum Tolerated Dose (MTD)
Timeframe: From data of initial dose until up to 21 days for treatment
Once the dose escalation stopping criteria are met, the MTD estimated by mTPI-2 will be the dose at which the probability of posterior mean of the DLT rate is between 25% and 35%, closest to 30%, and no more than 35%.
Objective Response Rate (ORR)
Timeframe: Up to 24 months
The sum of the number of cases with Complete Response (CR) and Partial Response (PR) in all treated tumor patients (CR + PR) divided by the total number of cases.
Progression Free Survival (PFS)
Timeframe: Up to 24 months
Time from start of treatment to progression of disease (PD) or death, whichever occurs first, in patients with tumors.
Duration of Response (DOR)
Timeframe: Up to 24 months
Time from the start of the first assessment of CR or PR in tumor patients to PD or death due to any reason.
Overall Survival (OS)
Timeframe: Up to 24 months
Time from start of treatment to death due to any reason.

- Subject must be at least 18 years of age at the time of signing the informed consent;
- Histological or cytological diagnosis of solid tumor that is advanced/metastatic solid tumor by pathology report and have progressed on, have been intolerant to, or have been ineligible for standard of care treatments.
- Subjects able to provide tumor blocks or 8~10 slides [fresh paraffin-embedded tumor tissue or archived paraffin-embedded tumor tissue (maximum time limit is not more than 2 years)] before the first dose of study intervention for biomarkers testing.
- At least one measurable lesion can be accurately measured per RECIST v1.1 as determined by the local site investigator/radiology assessment. Target lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions.

- Life expectancy of at least 3 months as assessed by the investigators.
- Subjects with adequate organ and bone marrow function confirmed by laboratory results within 7 days prior to the first dose.
- Has recovered from all toxicities from previous therapy with the exception of stable, chronic (>3 months) toxicities not considered a safety risk (e.g. alopecia, vitiligo), after consultation with the Sponsor.
- Subjects of childbearing potential (male or female) must use effective medical contraception during the study until 6 months after the last dose.
- Subjects must be able to provide documented voluntary informed consent.

- Has known active tuberculosis.
- Has known human immunodeficiency virus (HIV) infection that is not well controlled.
- Has any active viral hepatitis, hepatitis B or hepatitis C.
- Has had major surgery within 28 days prior to the first dose.
- Has known allergy or hypersensitivity to SKB518, or the excipients of SKB518.
- Has a history of interstitial lung disease (ILD) or a history of non-infectious pneumonitis that required steroids.
- Clinically serious lung injuries caused by lung diseases.
- History of documented severe dry eye syndrome.
- Has a history of allogeneic tissue/solid organ transplant.
- Has known uncontrollable effusion.
- Subjects who are vaccinated with live vaccine within 30 days before the first dose, or plan to be vaccinated with live vaccine during the study period.
- Has received strong cytochrome P450 (CYP3A4) inhibitors or inducers, or has received BCRP inhibitors within 2 weeks prior to the first dose.
- Subjects who received any chemotherapy, radiotherapy, immunotherapy, or biologic therapy treatment within 4 weeks; or who received any small molecular tyrosine kinase inhibitor, antitumor hormonal therapy, system immune-stimulator, or therapy with traditional Chinese medicines approved for antitumor treatment, etc. within 2 weeks before the first dose.
- Has an active infection requiring systemic therapy.
- Subjects with the disease that requires systemic corticosteroid therapy (prednisolone or equivalent dose of similar drugs at a dose of >10 mg/d) or other immunosuppressive therapy within 14 days before the first dose.
- Is currently participating and receiving study therapy in a study of an investigational agent or has participated and received study therapy in a study of an investigational agent or has used an investigational device within 28 days of fist dose.
- Before the first dose, the subject's condition deteriorates rapidly.
- Has a known psychiatric or substance abuse disorders.
- The Investigator considers other situations that will interfere with the evaluation of the study intervention or the safety of the subjects or the interpretation of the results of the study.
