The CTC offices are currently closed for refurbishment. Access to trial TMFs and patient records will be limited during this period. We will still be able to receive post during this time, but there may be a small delay in responding to this. Our fax lines may also be subject to disruption. Where possible, please direct all correspondence via email to trial-specific email addresses. We appreciate your patience and understanding.

Due to COVID-19 and current government guidance, UCL CTC staff continue to work remotely with limited access to the office. Please continue to email the trial specific mailbox with any urgent queries. For paper CRF trials, please continue to copy and scan CRFs to the trial inboxes (remove all patient identifiers except Trial Number and Initials) until further notice.

Lay summary:
A multicentre, phase III, open-label, randomized study in patients with advanced follicular lymphoma evaluating the benefit of maintenance therapy with Rituximab (MabThera®) after induction of response with chemotherapy plus Rituximab in comparison with no maintenance therapy
Design: PRIMA is an open label, international, multicentre, randomiszed study with two treatment phases.  During the first phase, patients will be evaluated for response to different induction regimens.  In the second phase patients responding to induction treatment will be randomiszed to maintenance therapy versus no further treatment (observation).
Treatment: Patients will be registered and will receive one of 3 regimens (CVP + Rituximab x 8 cycles), (CHOP x 6 cycles + Rituximab x 8 cycles) or (FCM x 6 cycles + Rituximab x 8 cycles) decided by the site in advance.  Patients that achieve a CR, Cru or PR are then randomised to either a further 12 cycles of Rituximab or Observation.  Patients on both arms will be seen every 8 weeks for 24 months.  Patients are then followed up for 5 years.
Key inclusion/exclusion criteria: Patients must be 18 or above and have histologically proven follicular lymphoma grade 1, 2 or 3a.  Patients must have at least one of the following: Bulky disease, B symptoms, Elevated serum LDH or b2 microglobulin, involvement of at least 3 nodal sites, symptomatic splenic enlargement, compressive syndrome or pleural/peritoneal effusion.  Patients can’t have CNS disease or poor renal or hepatic function.  Patients can’t have prior or concomitant malignancies except for non-melanoma skin cancer of adequately treated in situ cervical cancer.
Duration of recruitment: 2 years
The aim of this trial is to evaluate the benefit of maintenance therapy with rituximab as measured by progression-free survival (PFS) in comparison with no maintenance therapy after induction of response with chemotherapy plus rituximab in patients with high tumour burden follicular lymphoma
