About this study

Official title: A Phase 1, Multi-center, Open Label First-in-Human Study With ABBV-CLS-579 Alone and in Combination in Subjects With Locally Advanced or Metastatic Tumors

The purpose of this study is to see how safe and effective ABBV-CLS-579 is when used alone and in combination with a PD-1 target agent or with a VEGF TKI.

ABBV-CLS-579 is an investigational drug being developed for the treatment of tumors.

The trial aims to establish a safe, tolerable, and efficacious dose of ABBV-CLS-579 as monotherapy and in combination. The study will be conducted in three parts. Part 1 Monotherapy Dose Escalation, Part 2 Combination Dose Escalation, and Part 3 Combination Dose Expansion.

Part 1, ABBV-CLS-579 will be administered alone in escalating dose levels to eligible subjects who have advanced solid tumors.

Part 2, ABBV-CLS-579 will be administered at escalating dose levels in combination with a PD-1 targeting agent to eligible subjects who have advanced solid tumors.

Part 3, ABBV-CLS-579 will be administered at the determined recommended dose in combination with a PD-1 target agent or with a VEGFR TKI in subjects with locally advanced or metastatic, relapsed or refractory head and neck squamous cell carcinoma (HNSCC), relapsed or refractory non-small cell lung cancer (NSCLC), and advanced clear cell renal cell carcinoma (ccRCC).

Adult participants with a diagnosis of some solid tumors for which no effective standard therapy exists or has failed will be enrolled. Participants will receive study treatment until disease progresses or discontinued.

There may be a higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the course of the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects, and completing questionnaires.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ABBV-CLS-579, PD-1 inhibitor and VEGFR TKI in people with Advanced Solid Tumors Cancer, run by AbbVie at 17 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 24 inclusion and 20 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: finished, as of the sponsor's last update on 25 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 17 sites in United States, Spain, Japan, France, Israel 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 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.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Maximum Observed Plasma/Serum Concentration (Cmax) Of ABBV-CLS-579 (time frame: Baseline Up to Approximately Day 44). The study lists 24 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 25 Sep 2025.
