SNV1521 in Participants With Advanced Solid Tumors

June 23, 2026 updated by: Synnovation Therapeutics, Inc.

A Phase 1, Open-Label Dose Escalation and Expansion Study of SNV1521 in Participants With Advanced Solid Tumors

This study is testing a new medicine, SNV1521, for people with advanced cancers. The researchers want to find out if SNV1521 is safe, well-tolerated, and effective in treating solid tumors. They are investigating different doses in order to find the most effective and safe one. They are also investigating whether it can be combined with other cancer therapies.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Safety of SNV1521
Time Frame: From first dose through last dose (up to 13 months)
Treatment emergent adverse events (TEAEs)
From first dose through last dose (up to 13 months)
Tolerability of SNV1521
Time Frame: DLTs: From first dose through completion of first cycle (28 days)
Incidence and frequency of dose-limiting toxicities (DLTs) (Dose-escalation arm only)
DLTs: From first dose through completion of first cycle (28 days)

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
February 23, 2024

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
