Trial summary

Many tumor cells, in contrast to normal cells, have been shown to require the amino acid glutamine to produce energy for growth and survival. To exploit the dependence of tumors on glutamine, CB-839, a potent and selective inhibitor of the first enzyme in glutamine utilization, glutaminase, will be tested in this… Read more about this study

About this study

Official title: A Phase 1 Study of the Safety, Pharmacokinetics, and Pharmacodynamics of Escalating Oral Doses of the Glutaminase Inhibitor CB-839 in Patients With Advanced and/or Treatment-Refractory Hematological Malignancies

Many tumor cells, in contrast to normal cells, have been shown to require the amino acid glutamine to produce energy for growth and survival. To exploit the dependence of tumors on glutamine, CB-839, a potent and selective inhibitor of the first enzyme in glutamine utilization, glutaminase, will be tested in this Phase 1 study in patients with advanced hematologic malignancies.

This study is an open-label Phase 1 evaluation of CB-839 in subjects with hematological tumors. Patients will receive CB-839 capsules orally two or three times daily. The study will be conducted in 2 parts. Part 1 is a dose escalation study to identify the recommended Phase 2 dose and will enroll patients with advanced and/or treatment-refractory Non-Hodgkin's Lymphoma (NHL), Multiple Myeloma (MM), or Waldenström's macroglobulinemia (WM)

In Part 2, all patients will receive the recommended Phase 2 dose. This part will enroll patients with advanced and/or treatment-refractory Non-Hodgkin's Lymphoma (NHL), Multiple Myeloma (MM), or Waldenström's macroglobulinemia (WM). All patients will be assessed for safety, pharmacokinetics (plasma concentration of drug), pharmacodynamics (inhibition of glutaminase), biomarkers (biochemical markers that may predict responsiveness in later studies), and tumor response.

As an extension of Part 2, a cohort of patients with relapsed and refractory MM will be enrolled to receive low dose dexamethasone and CB-839. A second cohort of patients with relapsed or refractory disease following at least 2 prior treatment regimens will be enrolled to receive CB-839 in combination with standard-dose pomalidomide and low-dose dexamethasone to further evaluate this triple combination.

What is being measured

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

  1. Safety and tolerability of CB-839: Incidence of adverse events

    Measured: Every 21 days from study start until disease progression or unacceptable toxicity, assessed for an expected average of 6 months

Secondary outcomes (3)
  1. Pharmacokinetics: Area under the Curve (AUC) of CB-839 concentration in blood

    Measured: Study Days 1, 15, and 22

  2. Pharmacodynamics: % inhibition of glutaminase in blood

    Measured: Study Days 1 and 15

  3. Clinical activity: Change in tumor size from baseline

    Measured: Every 9 weeks (NHL) or 3 weeks (MM and WM), assessed for an expected average of 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CB-839, CB-839 and low dose dexamethasone and CB-839, pomalidomide, and low dose dexamethasone in people with Non-Hodgkin's Lymphoma (NHL) and Multiple Myeloma, run by Calithera Biosciences, Inc at 7 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 0 inclusion and 9 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 18 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 7 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 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?

Safety and tolerability of CB-839: Incidence of adverse events (time frame: Every 21 days from study start until disease progression or unacceptable toxicity, assessed for an expected average of 6 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 18 Jul 2018.
