About this study

Official title: A Phase 1b/2a, Open-label, Multicentre Study to Assess the Safety, Tolerability, Pharmacokinetics, and Antitumor Activity of Vactosertib in Combination With Imatinib in Patients With Advanced Desmoid Tumor (Aggressive Fibromatosis)

This is a phase I/II, open-label, non-randomized, multicentre study to evaluate the clinical activity of vactosertib plus imatinib in desmoid tumor. Based on the background, TGF-β inhibition as a potential therapeutic target for desmoid tumor and convey significant implications for the clinical development. Therefore, investigator will conduct the phase II trial of vactosertib in combined with imatinib in desmoid tumor.

Read the detailed description

Desmoid tumor (aggressive fibromatosis) is a mesenchymal neoplasm associated with mutations, resulting in -catenin-mediated transcriptional activation. It is composed of a clonal proliferation of mesenchymal, fibroblast-like cells occurred sporadic or as a part of familial adenomatosis polyposis. This tumor has high local recurrence rate after complete excision (~40%). Therefore, although lacking metastatic capability, patients experience repeated recurrence with attendant severe morbidity. Various systemic therapy using NSAID, cytotoxic agent (doxorubicin and vinblastine), biologic agents (tamoxifen, low-dose interferon), and tyrosine kinase inhibitors (imatinib) are recommended with modest activity. Among them, imatinib has shown promising activity and approved as standard treatment for desmoid tumor. However, still there is modest response (10-15% responses) and further combination strategy is warranted to improve antitumor efficacy.

The transforming growth factor-β (TGF-β) family of cytokines has 33 members in humans, including TGF-β isoforms, activins, bone morphogenetic proteins (BMPs), and growth and differentiation factors (GDFs). These factors regulate growth, survival, differentiation and migration of cells, and have important roles during embryonal development and in the control of adult tissue homeostasis. During carcinogenesis, TGF-β has a dual role; initially it suppresses tumorigenesis by inducing growth arrest and promoting apoptosis, however, in advanced cancers, where TGF-β often is overexpressed. In addition, TCGA (the cancer genome atlas) pan-cancer also demonstrated high expression of TGF-β responsive signature in desmoid tumor. Regarding the combination, TEW-7197 (vactosertib), a TGF-β inhibitor and imatinib demonstrated synergistic effect in vitro and xenograft model. Compared to imatinib alone, administration of imatinib plus vactosertib to mice significantly delayed disease relapse and prolonged survival. Collectively, these results indicate that vactosertib may be a promising candidate for a new therapeutic strategy.

Based on the background, TGF-β inhibition as a potential therapeutic target for desmoid tumor and convey significant implications for the clinical development. Therefore, investigator will conduct the phase II trial of vactosertib in combined with imatinib in desmoid tumor.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing vactosertib/imatinib combination in people with Desmoid Tumor, run by Hyo Song Kim at 1 site in South Korea.

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 13 inclusion and 11 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 13 May 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. 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?

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?

adverse event (time frame: 4 weeks). The study lists 2 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 13 May 2024.
