Arms and Interventions

Arm Intervention/Treatment
Experimental: Dose escalation

Drug: CS5001
CS5001 will be administered every 3 weeks (21 days) by intravenous (IV) infusion, and 3 weeks (21 days) is considered as one treatment cycle.

Experimental: Dose expansion

Drug: CS5001
CS5001 will be administered every 3 weeks (21 days) by intravenous (IV) infusion, and 3 weeks (21 days) is considered as one treatment cycle.

Outcome Measures

Primary Outcome Measures

  1. Maximum Tolerated Dose (MTD) of CS5001 if any (for dose escalation part) [About 6 months]

    Participants will receive CS5001 for injection once every three weeks. The MTD will be determined by the number of participants who experience a dose limiting toxicity (DLT).

  2. Recommended Phase 2 Dose(RP2D) of CS5001 (for dose escalation part) [About 6 months]

    The selection of RP2D will be based on consideration of overall safety information together with available pharmacokinetic, pharmacodynamic, and efficacy data. The RP2D may be the MTD or may be a lower dose within the tolerable dose range.

  3. Incident and severity of adverse events [Until 90 days since the last dose of investigational product or until initiation of a new anti-cancer treatment, whichever occurs first]

Secondary Outcome Measures

  1. Concentration of CS5001 total antibody, prodrug and the free cytotoxin [Up to 30 days since the last dose of or until initiation of a new anti-cancer treatment, whichever occurs first]

  2. Concentration of anti-CS5001 antibodies [Up to 30 days since the last dose of or until initiation of a new anti-cancer treatment, whichever occurs first]

Other Outcome Measures

  1. Anti-tumor activity of CS5001 at RP2D in patient with selected advanced cancers (For dose expansion part) [About up to 12 months]
