About this study

Official title: A Multicenter Phase 2 Study of the Bruton's Tyrosine Kinase (Btk) Inhibitor, PCI-32765, in Subjects With Relapsed or Relapsed and Refractory Multiple Myeloma

The primary objective of this study is to determine the efficacy of PCI-32765, both as a single agent and in combination with dexamethasone, in subjects with relapsed or relapsed and refractory Multiple Myeloma (MM)

Read the detailed description

Bruton's tyrosine kinase (Btk) is an enzyme that is present in hematopoietic cells other than T cells and is necessary for downstream signal transduction from various hematopoietic receptors including the B cell receptor as well as some Fc, chemokine, and adhesion receptors, and is crucial for both B cell development and osteoclastogenesis. Although down-regulated in normal plasma cells, Btk is highly expressed in the malignant cells from many myeloma patients and some cell lines. PCI 32765 is a potent and specific inhibitor of Btk currently in Phase 2 clinical trials. The current study is designed and intended to determine the effects of PCI-32765 in subjects with MM.

What is being measured

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

  1. The Clinical Benefit Response (CBR)

    The clinical benefit response (CBR) rate, defined as the proportion of subjects who achieved stringent complete response (sCR), complete response (CR), very good partial response (VGPR), partial response (PR), or minimal response (MR) as assessed by the modified International Myeloma Working Group (IMWG) response criteria

    Measured: From the date of first study treatment until disease progression per IMWG, up to 60 months

Secondary outcomes (10)
  1. To Evaluate the Efficacy of PCI-32765 by Assessing ORR

  10. Duration of Response (DOR)

    The time interval between the date of initial documentation of a response and the date of first documented evidence of progressive disease, death, or date of censoring for the subjects not progressed/died. The censoring date is the last adequate tumor assessment date.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing PCI-32765 and Dexamethasone in people with Multiple Myeloma, run by Pharmacyclics LLC. at 11 sites 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 8 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: finished, as of the sponsor's last update on 10 Mar 2020. 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. 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 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?

Yes. Results are posted in the registry (first posted 26 Jun 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

The Clinical Benefit Response (CBR) (time frame: From the date of first study treatment until disease progression per IMWG, up to 60 months). 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 10 Mar 2020.
