Registration Number
NCT06163391
Lead Sponsor
SOTIO Biotech AG
Brief Summary

This is a Phase 1, open-label, dose escalation study to assess the safety, tolerability, and preliminary efficacy of SOT201 as monotherapy for participants aged 18 years or above with advanced unresectable or metastatic solid tumors

During dose escalation, the recommended dose(s) of SOT201 given every 3 weeks (Q3W) will be determined

Detailed Description

Duration of the study for a participant will include:

Screening period: Up to 21 days before day 1 of cycle 1 (can be prolonged up to 42 days, if required due to fresh biopsy) Treatment Period: enrolled and exposed participants will receive continuous treatment until progressive disease (PD), or an occurrence of an unacceptable AE, a withdrawal of consent, or until other permanent discontinuation criteria described in the protocol are met.

End of treatment will occur within 7 (+7) days after the SOT201 discontinuation, and Follow-up period.

Every 30 (±2) days until 90 (+7) days after the final dose of SOT201, until disease progression, the start of new anticancer therapy, death, or withdrawal of participant's consent, whichever comes first.

Primary Outcome Measures
NameTimeMethod
Number and percentages of participants with treatment-emergent adverse events (TEAEs)from patient signing the ICF up to 90 (+7) days after the last dose of SOT201, assessed approximately up to 3 years

A TEAE is defined as an AE that started or worsened at or after the start of trial treatment Presence of TEAEs, SAEs, and lab abnormalities, according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0

Number of participants with dose-limiting toxicities (DLTs)21 days of Cycle 1 plus 7 days of cycle 2 per cycle

DLTs will be defined using NCI CTCAE version 5.0

Secondary Outcome Measures
NameTimeMethod
Characterization of maximum concentration (Cmax) of SOT201Time Frame: From Day 1 of Cycle 1 to Cycle 3, from cycle 4 every other cycle (4, 6, 8), and from cycle 8 at quarterly frequency (11, 14, 17.) until cycle 20]

Maximum plasma concentration observed

Characterization of pre-dose concentration (Ctrough) of SOT201From Day 1 of Cycle 1 to Cycle 3, from cycle 4 every other cycle (4, 6, 8), and from cycle 8 at quarterly frequency (11, 14, 17..) until cycle 20

Pre-dose trough SOT201 concentrations

Objective response rate (ORR)From Day 1 of Cycle 1 until disease progression or start new anticancer therapy, whichever comes first, assess to up to approximately 3 years

Proportion of patients who have a confirmed complete response (CR) or a partial response (PR), as the best overall response (BOR) determined by the Investigator as per the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1

Incidence of anti-drug antibodies (ADAs) against SOT201Day 1 until 30 (±2) days after the last dose of SOT201

Incidence of patients with anti-drug antibodies

Characterization of area under the curve (AUClast, AUCinf, AUCtau) of SOT201From Day 1 Cycle 1 to Cycle 3, from cycle 4 every other cycle (4, 6, 8), and from cycle 8 at quarterly frequency (11, 14, 17.) until cycle 20

Area under the concentration versus time curve calculated using the trapezoidal method during a dosing interval (tau)

Characterization of time to maximum concentration (Tmax) of SOT201From Day 1 of Cycle 1 to Cycle 3, from cycle 4 every other cycle (4, 6, 8), and from cycle 8 at quarterly frequency (11, 14, 17..) until cycle 20

Time to maximum concentration of SOT201

Duration of response (iDoR)From Day 1 of Cycle 1 until disease progression or start new anticancer therapy, whichever comes first, assess to up to approximately 3 years

DoR is defined as the time from first documented evidence of confirmed CR or PR until progressive disease (PD) determined by Investigator per RECIST 1.1 or death from any cause, whichever occurs first

Clinical benefit rate (iCBR)From Day 1 of Cycle 1 until disease progression or start new anticancer therapy, whichever comes first, assess to up to approximately 3 years

including confirmed CR or PR at any time or stable disease (SD) of at least 6 months determined by Investigator per RECIST 1.1

Progression-free survival (iPFS)From Day 1 of Cycle 1 until disease progression or start new anticancer therapy, whichever comes first, assess to up to approximately 3 years

PFS is defined as the time from the date of first administration of IMP to the date of the first documented disease progression determined by Investigator as per RECIST 1.1 or death from any cause, whichever occurs first
