Objective of this trial is to establish the efficacy of an upfront targeted therapy consisting of Chlamydophila psittaci (Cp)-eradicating therapy with prolonged administration of doxycycline followed by eradication monitoring and antibiotic re-treatment at infection re-occurrence in patients with newly diagnosed ocular adnexae marginal zone lymphoma The primary endpoint is the 2-year progression-free survival (PFS) of patients with newly diagnosed stage-IE lymphoma treated with the experimental strategy.

Condition Intervention Phase
Marginal Zone Lymphoma of Ocular Adnexal Drug: Doxycycline Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: International Prospective Phase 2 Trial Addressing the Efficacy of First-line Chlamydophila Psittaci-eradicating Therapy With Protracted Administration of Doxycycline Followed by Eradication Monitoring and Antibiotic Re-treatment at Infection Re-occurrence in Patients With Newly Diagnosed Ocular Adnexal Marginal Zone Lymphoma (OAMZL)

Primary Outcome Measures:
  • progression-free survival (PFS) [ Time Frame: 2-year from start of treatment ]
    from the date of the start of treatment to relapse, progression or death, or to the last date of follow-up

Enrollment: 34
Study Start Date: March 2013
Estimated Study Completion Date: September 2023
Primary Completion Date: May 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Doxycycline Drug: Doxycycline
All enrolled patients will be treated with doxycycline 100 mg bid daily, orally, for four weeks followed by four weeks rest, repeated for three cycles. Response will be assessed by MRI (magnetic resonance imaging) and ophthalmologic examination at the end of the planned treatment. Patients who will achieve complete response, partial response or have a stable disease at 3 months from upfront doxycycline will be monitored for infection re-occurrence and assessed for response with MRI and ophthalmologist evaluation every six months for the first five years.
