Study arms

  • Experimental
    Experimental: clarithromycin and lenalidomide

    CLARITHROMYCIN: daily orally administration in cycles of 28 days; 500mg film-coated tablets LENALIDOMIDE: every cycle of treatment lasts 28 days; daily orally administration is of 21 consecutive days with a week of rest. 20mg capsule hard. The maximum treatment duration is 12 months.

    Drug: clarithromycin and lenalidomide

Interventions

  • Drugclarithromycin and lenalidomide

    Drug pages: Clarithromycin · Lenalidomide

    Each treatment course will consist of: Oral Lenalidomide (Revlimid) once daily for 21 days at a dose 20 mg; in case of drug-related adverse events the dose can be reduced to 15 and 10 mg/day; Oral Clarithromycin 500 mg twice daily for 28 days. Courses will be repeated every 28 days. After the first 3 courses patients with stable disease or better response will be given another three courses. Patients with complete remission or disease progression after 6 courses will be taken off study, while patients with partial response or stable disease will receive 3 further courses of treatment. Again, patients with complete response or disease progression will stop therapy, while patients with partial response/stable disease will receive 3 further courses up to a maximum of 12 courses in total.

What researchers measure

Primary outcomes

  1. Tumor response assessment

    The primary outcome measure is tumour response assessed according to the Revised Response Criteria for Malignant Lymphoma, either clinically (including appropriate imaging procedures) or endoscopically and histologically (in patients affected by gastric lymphoma, according to the GELA scoring system).

    Time frame: During the active treatment period after the 3rd cycles of both drugs administration

Secondary outcomes

  1. Adverse Events assessments

    1. Treatment-emergent adverse events (AEs) incidence, severity and relationship to study treatment. 2. Time from first IMP administration to assessment of disease progression or death due to any cause, whichever occurs earlier.

    Time frame: During the active treatment period

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Apr 2017 to primary completion in Nov 2019, 31 months.

Of 70 non-industry phase 2 interventional studies under Lymphoma, B-Cell, Marginal Zone, half reached primary completion within 69 months of starting (the median), counting those still running; a quarter within 50 and three quarters within 110. This study's 31 months is below that.

Counting every sponsor, half of 86 studies reached it within 67 months; a quarter within 37 and three quarters within 101.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 30, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
