About this study

Official title: Multicentre, Prospective Study of First-line Antibiotic Therapy for Early-stage H. Pylori-Positive Gastric Pure (de Novo) Diffuse Large B-cell Lymphoma and Potential Predicting Factor for Treatment Outcome

Aims: A nationwide study to prospectively validate

  1. The complete histological and molecular remission rate for antibiotics as 1st-line therapy for early-stage Hp-positive gastric pure (de novo) DLBCL
  2. The durability of complete histological remission after antibiotics
  3. The usefulness of pattern of NF-kB, BCL10, BAFF, and CagA by IHC staining in prospectively predicting the Hp-dependence of gastric pure (de novo) DLBCL
  4. The frequency of t(11;18)(q21;q21) translocation in gastric pure (de novo) DLBCL in Taiwan.
  5. The association between the CYP2C18/CYP2C19 genetic polymorphisms and eradication of Hp infection after antibiotics.
Read the detailed description

The study will validate the use of antibiotics as first-line therapy for stage IE (and perhaps IIE-1) Hp-positive gastric pure (de novo) DLBCL. The status of NF-kB, BCL10, BAFF, and CagA IHC nuclear staining will help to tailoring the treatment for early-stage gastric pure (de novo) DLBCL. And 50-60% of stage IE / IIE-1 pure (de novo) DLBCL patients can be cured by 2-weeks of antibiotics rather than the 6-months of relatively toxic front-line systemic chemotherapy. The investigators shall also elucidate the distribution of CYP2C18/19 in patients with pure (de novo) DLBCL and their association with the efficacy of sequential antibiotics for eradication of Hp infection.

What is being measured

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

  1. The pathologic complete remission rate (%) for antibiotics as 1st-line therapy for early-stage Hp-positive gastric pure (de novo) DLBCL

    Measured: 10 years

  2. The median time to pathologic complete remission (months) after completion of antibiotics for Hp-dependent gastric pure (de novo) DLBCL (patients have pCR after Hp eradication therapy [antibiotics])

    Measured: 10 years

  3. The relapse-free survival of early-stage Hp-positive gastric pure (de novo) DLBCL who received antibiotics as 1st-line therapy

    A nationwide study to prospectively validate

    Measured: 10 years

Secondary outcomes (2)
  1. The overall survival of early-stage Hp-positive gastric pure (de novo) DLBCL who received antibiotics as 1st-line therapy

    Measured: 10 years

  2. The Hp eradication rate (%)

    Measured: 10 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Lansoprazole, Amoxicillin, Clarithromycin, Metronidazole in people with Gastric Diffuse Large B-cell Lymphoma, run by National Health Research Institutes, Taiwan at 1 site in Taiwan.

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 7 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 25 Mar 2016. 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 Taiwan. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Bor-Rong Chen, BS (886-2-26534401 ext. 25162, brong@nhri.org.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The pathologic complete remission rate (%) for antibiotics as 1st-line therapy for early-stage Hp-positive gastric pure (de novo) DLBCL (time frame: 10 years). The study lists 3 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 25 Mar 2016.
