About this study

Official title: A Phase I/II, Multi-center, Open Label Study of DYP688 in Patients With Metastatic Uveal Melanoma (MUM) and Other GNAQ/11 Mutant Melanomas

This is a FIH, phase I/II, open label, multi-center study of DYP688 as a single agent. The purpose of this study is to characterize the safety, tolerability, and anti-tumor activity of DYP688 as a single agent in patients with metastatic uveal melanoma (MUM) and other melanomas harboring GNAQ/11 mutations.

Read the detailed description

This is a First in Human (FIH), phase I/II, open label, multi-center study of DYP688 as a single agent. There will be two parts to this study: a phase I, dose escalation part followed by a phase II part. Dose escalation will be conducted in patients with MUM and other melanomas harboring GNAQ/11 mutations. Once the MTD and/or RD(s) is determined in the dose escalation part, the study may continue with a phase II part. The phase II part will be conducted in two groups of patients with MUM, a prior tebentafusp-treated group and a tebentafusp-naïve group. In addition to MUM, a third group of patients with non-uveal GNAQ/11 mutant melanomas may also be explored. This cohort may be opened based on emerging data from the dose escalation part of the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Phase I (Dose Escalation): Incidence and severity of dose limiting toxicities (DLTs) during the first 28 days of treatment.

    A DLT is defined as an adverse event or abnormal laboratory value of Common Terminology Criteria for Adverse Events (CTCAE) grade ≥ 3 assessed as unrelated to disease, disease progression, intercurrent illness, or concomitant medications that occurs within the first cycle of treatment with DYP688. Other clinically significant toxicities may be considered to be DLTs, even if not CTCAE grade 3 or higher.

    Measured: 28 days

    Measured: 17 months

  12. Phase II: Incidence and severity of adverse events (AEs) and serious adverse events (SAEs)

    Assessment of safety of DYP688 as a single agent

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing DYP688 in people with Metastatic Uveal Melanoma, run by Novartis Pharmaceuticals at 11 sites in 7 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 28 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in United States, Australia, Germany, France, Netherlands and 2 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase I (Dose Escalation): Incidence and severity of dose limiting toxicities (DLTs) during the first 28 days of treatment. (time frame: 28 days). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05415072, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Jul 2026.
