FLUORO: This Phase II trial is trying to understand the effect of chemotherapy (obinutuzumab and atezolizumab) with or without radiotherapy in people with advanced follicular lymphomaFrontline Treatment of Follicular Lymphoma With AtezolizUmab and Obinutuzumab With and Without RadiOtherapy

Clinical summary


This is a non-randomised trial with one experimental arm. All participants will receive an intravenous infusion of Obinutuzumab (1000mg) + Atezolizumab (1200mg) q3/52 x 6 cycles (plus 1000mg Obinutuzumab on day 8 and 15 of cycle 1). Responding participants (those with a partial response (PR) or stable disease (SD)) who do not achieve a CR at the end of cycle 2 will receive involved site radiotherapy (4Gy, 2 fractions) between cycle 3 and 4. At the end of cycle 6 and completion of the induction phase, responding participants (CR/PR/SD) will receive maintenance phase Obinutuzumab (1000mg intravenously) q8/52 for up to 12 cycles.


This trial is treating patients with follicular lymphoma.

  2. Male or female aged ≥ 18 years or older at written informed consent
  3. Histologically proven FL grade 1-3A according to the current World Health Organisation classification (2016) including all morphological variants. The B-cell nature of the proliferation must be verified by the positivity with an anti-CD20 antibody
  4. No previous chemotherapy, or other investigational drug for this indication apart from focal RT
  5. Stage I disease not amenable to single-agent definitive-dose RT, stage II, III or IV (as per Ann Arbor criteria - see appendix 1), suitable for treatment with non-curative intent
  6. At least one site of radiographically measurable disease not previously irradiated (at least one bi-dimensionally measurable site of disease: nodal disease >1.5 cm or an extranodal lesion > 1.0 cm in longest perpendicular diameter)
  7. Deemed to need treatment by treating Investigator. Reasons for treatment can include, but are not limited to:

    • Any nodal or extranodal tumour mass >7cm AND/OR multiple extranodal disease sites
    • Involvement of at least 3 sites each with diameter >3cm
    • Symptomatic splenic enlargement
    • Organ involvement/compression
    • Ascites or pleural effusion
    • (LDH) elevated
    • Presence of systemic symptoms
    • Disease progression in preceding 3 months
    • Evidence of marrow infiltration with marrow compromise. (e.g. haemoglobin, WBC or platelet count below lower limit of institutional normal range)
  8. Adequate bone marrow function within 7 days prior to registration defined as:

    • ANC ≥1.0x109/L
    • WBC ≥2.0x109/L
    • Platelets ≥100x109/L (with no platelet transfusion in the preceding 14 days)
    • Haemoglobin ≥90 g/L (with no red blood cell transfusion in the preceding 14 days) Unless these are attributed to bone marrow infiltration by lymphoma. In cases were one or more results are lower than those specified above due to bone marrow infiltration by FL, patient may be eligible following consultation with the CPI.
  9. Adequate organ function within 7 days prior to registration, defined as

    • Total bilirubin ≤1.5 x upper ULN with the exception of patients with known Gilbert's syndrome may be included if their total bilirubin is ≤3.0 x ULN and direct bilirubin ≤1.5 x ULN)
    • AST and(ALT) ≤3 x ULN
    • Adequate renal function with serum creatinine ≤1.5 x ULN or CrCl ≥ 40mL/min (using Cockroft-Gault formula, see Appendix 2)

    • For patients receiving therapeutic anticoagulation: stable anticoagulant regimen
  10. ECOG performance status 0-2 (see Appendix 3)
  11. Life expectancy greater than 6 months
  12. Patients of childbearing potential must adhere to the following:

    • Female patients of childbearing potential must have a negative serum pregnancy test within 7 days prior to registration Note: A woman is considered to be of childbearing potential if she is postmenarchal, has not reached a postmenopausal state (> 12 continuous months of amenorrhea with no identified cause other than menopause), and is not permanently infertile due to surgery (i.e., removal of ovaries, fallopian tubes, and/or uterus) or another cause as determined by the investigator (e.g., Müllerian agenesis). The definition of childbearing potential may be adapted for alignment with local guidelines or regulations.
    • Female patients of childbearing potential must be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the trial through to 18 months after the last dose of treatment. Women must refrain from donating eggs during this same period.

    Note: The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not adequate methods of contraception.

    • Women must not be breastfeeding during study treatment and for 18 months after the last dose of obinutuzumab/study treatment.
    • Male patients must agree to use an adequate method of contraception for the course of the trial through to 18 months after the last dose of treatment. Men must refrain from donating sperm during this same period.
  13. Able to comply with the study protocol requirements and follow-up procedures.
