Safety and Activity of SNX-5422 Plus Ibrutinib in CLL
A Phase 1 study testing SNX-5422 plus ibrutinib in people with Cancer, run by Esanex Inc. at 1 site in United States.
Trial summary
SNX-5422 is a prodrug of SNX-2112, a potent, highly selective, small molecule inhibitor of the molecular chaperone heat shock protein 90 (HSP90). Hsp90 inhibitors may overcome ibrutinib resistance in Mantle cell lymphomas and this study will investigate whether the addition of SNX-5422 to an established dose of… Read more about this study

About this study
Official title: A Phase 1, Open-label Study of SNX-5422 and Ibrutinib in Chronic Lymphocytic Leukemia Subjects With a Mutation in Bruton's Tyrosine Kinase
SNX-5422 is a prodrug of SNX-2112, a potent, highly selective, small molecule inhibitor of the molecular chaperone heat shock protein 90 (HSP90). Hsp90 inhibitors may overcome ibrutinib resistance in Mantle cell lymphomas and this study will investigate whether the addition of SNX-5422 to an established dose of ibrutinib will result in the removal of mutated BTK from blood mononuclear cells and/or prevents or delays disease progression of subjects with CLL
Read the detailed description
Chronic lymphocytic leukemia (CLL) is the most prevalent leukemia in adults and is not considered curable outside of allogeneic stem cell transplantation.
BTK is a critical kinase in the B cell receptor signaling pathway. This pathway is amplified in CLL and results in amplification of proliferation and anti-apoptotic signals. By inhibiting BTK, ibrutinib eliminates the activation of these pro-survival pathways and microenvironment survival signals. While response to ibrutinib has been high with therapy well-tolerated overall, some patients have relapsed while others have been taken off therapy for toxicity or other reasons. Relapse in CLL can be mediated by at least two separate mechanisms. One is by mutations in BTK, which both decrease ibrutinib's affinity for BTK, and also changes the binding from irreversible to reversible. This is a proof of concept study to investigate whether the addition of SNX-5422 to an established dose of ibrutinib will reduce mutated BTK from CLL cells and/or prevents or delays disease progression of subjects with CLL.
This is an open-label study of SNX-5422 combined with ibrutinib. In each 28 day cycle, SNX-5422 will be dosed in the morning once every other day for 21 days, followed by a 7-day drug-free period. Subjects will continue to receive daily oral ibrutinib at their established dose level in the afternoon every day for 28 days. cycle

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing SNX-5422 plus ibrutinib in people with Cancer, run by Esanex Inc. at 1 site in United States.
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 17 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: withdrawn, as of the sponsor's last update on 30 Jul 2018. 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 United States. 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 was withdrawn before enrolling participants, so there are no results.
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?
Efficacy of the combination of SNX-5422 and ibrutinib (time frame: Every 12 weeks up to 52 weeks). 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 30 Jul 2018; AzTrials last refreshed its copy on 8 Nov 2026.
