Inclusion Criteria

Part A (phase I and phase IIa) and Part C (phase IIa Pharmacokinetic
Cohort):
1. Histologically confirmed (by WHO classification) relapsed incurable
non-Hodgkin B-cell lymphoma of following subtypes; follicular grade IIIIA
(for Part C, this excludes patients meeting Part B criteria, who
should enter Part B), marginal zone, small lymphocytic,
lymphoplasmacytic, mantle cell.
2. Age = 18 years.
3. Part A: A pre-study WHO performance status of 0-1; Part C: WHO
performance status of 0-2.
4. Life expectancy should be = 3 months.
5. <25% tumour cells in bone marrow biopsy (biopsy taken from a site
not previously irradiated).
6. Measurable disease by radiological methods.
7. Women of childbearing potential must:
a) understand that the study medication is expected to have teratogenic
risk.
b) have a negative pregnancy test.
c) agree to use, and be able to comply with, effective contraception
without interruption, 4 weeks before starting study drug, throughout
study drug therapy and for 12 months after end of study medication
therapy, even if she has amenorrhoea.
8. Male subjects must agree to use condoms during intercourse
throughout study drug therapy and the following 12 months.
9. Patients previously treated with native rituximab are eligible.
10. The patient is willing and able to comply with the protocol, and
agrees to return to the hospital for follow-up visits and examination.
11. The patient has been fully informed about the study and has signed
the informed consent form.

1. Histologically confirmed (by WHO classification) relapsed non-
Hodgkin B-cell FL (grade I-IIIA).
2. Male or female aged = 18 years.
3. Received at least 2 prior systemic anti-neoplastic or immunotherapy
based regimens (maintenance therapy following a CR/PR is not
considered to be a separate line of therapy). Systemic regimens
including agents such as idelalisib or other PI3K inhibitors qualify as a
prior line of therapy.
4. Prior therapy must have included a rituximab/anti-CD20 agent and an
alkylating agent – which may be been administered in separate
regimens.
5. Patients must be refractory to any at least one previous regimen that
contained rituximab or an anti-CD20 agent, with refractoriness defined
as:
i. no response (no CR or PR) during therapy, or
ii. a response (CR/PR) lasting less than 6 months after the completion of
a regimen including rituximab/anti-CD20 therapy (including occurrence
of progressive disease (PD) during rituximab/anti-CD20 maintenance
therapy, or within 6 months of completion of maintenance therapy).
6. WHO performance status of 0-2.
7. Life expectancy of = 3 months.
8. Bone marrow tumour infiltration < 25% (in biopsy taken from a site
not previously irradiated).
9. Measurable disease by CT or MRI: longest diameter (LDi) > 1.5 cm for
nodal lesion, LDi > 1.0 cm for extra nodal lesion on an assessment
performed during the screening period.
Criteria 10 and 11 must be satisfied within 72 hours of the
administration of rituximab:
10. ANC = 1.5 x 109/L.
11. Platelet count = 100 x 109/L.
Criteria 12 to 15 must be verified at time of eligibility review within 2
weeks prior to rituximab administration:
12. Haemoglobin = 9.0 g/dL.
13. Total bilirubin =1.5 x upper limit of normal (ULN) (except patients
with documented Gilbert's syndrome [< 3.0 mg/dL]).
14. Liver enzymes: Aspartate transaminase (AST); Alanine transaminase
(ALT) or ALP = 2.5 x ULN (or = 5.0 x ULN with liver involvement by
primary disease).
15. Adequate renal funct
