About this study

Official title: A Phase 1/2a Open-label Study of Pralatrexate and Gemcitabine With Vitamin B12 and Folic Acid Supplementation in Patients With Relapsed or Refractory Lymphoproliferative Malignancies

This study is for patients with lymphoproliferative malignancies that have progressed after receiving a previous treatment (relapsed) or are no longer responding to treatment (refractory). To be in this study, patients must have certain types of Hodgkin's lymphoma (HL), peripheral T-cell lymphoma (PTCL), or B-cell lymphoma, including Waldenstrom's macroglobulinemia.

This study is being done to find doses of the combination of pralatrexate and gemcitabine with vitamin B12 and folic acid that can be safely given to patients with these types of lymphoma and explore the effectiveness of the treatment.

What is being measured

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

  1. Objective Responses Assessed by International Workshop Criteria (IWC)

    Number of participants who achieved an objective response. Objective response was defined as a tumor response assessment of either complete response (CR) or partial response (PR) and was determined only for patients with measurable disease at baseline. A tumor response assessment reported by IWC without PET was used for any analyses in cases where an IWC+PET evaluation was not done.

    Measured: Assessed every 8 weeks (+/- 1 week) for Phase II and no less than every 3 cycles for Phase I

Secondary outcomes (2)
  1. Duration of Response

    Duration of response was defined as the number of days between the date of first tumor response assessment of objective response to the time of the first tumor response assessment of progressive disease (PD) or death due to any cause (date of first PD assessment or death - date of first objective response assessment + 1)

    Measured: Response assessments were performed no less than every 3 cycles in the Phase 1 part of the study and every 8 weeks (± 1 week) in the Phase 2a part of the study

  2. Progression-free Survival (PFS) Time

    PFS time was calculated as the number of days from study day 1 to the date of PD or death, regardless of cause (date of PD or death - study day 1 + 1).

    Measured: Response assessments were performed no less than every 3 cycles in the Phase 1 part of the study and every 8 weeks (± 1 week) in the Phase 2a part of the study

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Pralatrexate Injection, Gemcitabine Hydrochloride and Vitamin B12 in people with Relapsed or Refractory Lymphoproliferative Malignancies and Hodgkin's Lymphoma, run by Acrotech Biopharma Inc. at 15 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 10 inclusion and 21 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 7 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 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 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?

Yes. Results are posted in the registry (first posted 18 Sep 2012). 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?

Objective Responses Assessed by International Workshop Criteria (IWC) (time frame: Assessed every 8 weeks (+/- 1 week) for Phase II and no less than every 3 cycles for Phase I). 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 7 Jan 2020.
