Arms Assigned Interventions
Experimental: clarithromycin, oral, high dose
2 g/day clarithromycin (once a day) for 14 days followed by 7 days interval to be repeated for 4 cycles in total

Detailed Description:
A 6-month regimen of oral clarithromycin has been associated with a 35% ORR in patients with relapsed/refractory marginal zone B-cell lymphoma. Responses were more common among patients with conjunctival lymphoma. This could be explained at least in part by the elimination of clarithromycin by tears, suggesting that a higher tumor bioavailability of this antibiotic could result in a higher activity. Thus, a higher dose of clarithromycin could be associated with a higher tumor bioavailability in tissues other than the conjunctiva.
