DA-EPOCH-RM: A Phase II Study Evaluating the Efficacy and Safety of Metformin in Combination With Standard Induction Therapy (DA-EPOCH-R) for Previously Untreated C-myc+ Diffuse Large B-Cell Lymphoma
Newly diagnosed histologically confirmed c-myc+ de novo DLBCL. Metformin 500 mg daily x 1
week, then 500 mg twice daily (BID) x 2 weeks, then 850 mg twice daily until 1 month after
last cycle of chemo-immunotherapy.
DA-EPOCH-R every 21 days x 4 cycles (CNS prophylaxis single or triple therapy given
intrathecally each cycle to patients deemed appropriate by treating physician).
Restage after 4 cycles with CT. Complete remission or partial remission: complete 2 more
cycles or radiation therapy (XRT) consolidation per physician. Stable or progressive disease
will go on to salvage therapy off study.

DA-EPOCH-R every 21 days x 4 cycles (CNS prophylaxis single or triple therapy given

Restage after 4 cycles with CT. Complete remission or partial remission: complete 2 more
cycles or radiation therapy (XRT) consolidation per physician. Stable or progressive disease
will go on to salvage therapy off study.
Subject admitted to in-patient care for day 1 or each cycle and discharged on day 5. On day
6, subject receives Rituximab in outpatient infusion facility.
Metformin is dispensed on day 1 of each cycle and taken as follows: Cycle 1 days 1-7 500 mg
daily. Days 8-21, 500 mg twice daily. Cycle 2 through end of treatment, metformin given 850
mg twice daily.
Inpatient treatment: DA-EPOCH every 21 days Etoposide (VP-16) 50 mg/m2/d civi d1-4
(continuous infusion) Prednisone 60 mg/m2 BID po d1-5 Vincristine 0.4 mg/m2/d civi d 1-4
(continuous infusion) Doxorubicin (Adriamycin) 10 mg/m2/d civi d1-4 (continuous infusion)
Cyclophosphamide (Cytoxan) 750 mg/m2 IV over 15 min d5 If clinically indicated, patients who
are deemed appropriate for central nervous system (CNS) prophylaxis by their treating
physician will receive either single agent intrathecal methotrexate (12 mg) or triple therapy
(15 mg methotrexate, 30 mg cytarabine, 30 mg hydrocortisone) with each cycle of chemotherapy.
Rituximab 375 mg/m2 IV every 21 days on D6-8 post DA-EPOCH (per standard institutional
guidelines) DA-dose adjustment paradigm based on twice weekly complete blood count (CBC)
(dose adjustment above starting doses apply to Etoposide (VP-16), Doxorubicin (Adriamycin)
and Cyclophosphamide (Cytoxan). If nadir absolute neutrophil count(ANC)>500/microliter (uL),
20% increase in all 3 drugs. If nadir<500/uL on 1 or 2 measurements, same doses as last
cycle. If nadir <500/uL on at least 3 measurements, or nadir platelet <25,000/uL on 1
measurement, 20% decrease in Etoposide, Doxorubicin and Cyclophosphamide below last cycle.
Filgrastim (Neupogen) 5 mcg/kg sc qd beginning on d6 until ANC>5,000/uL or Pegfilgrastim
(Neulasta) 6 mg sc 24-72 hours post chemotherapy.
Restaging with CT scans is done after cycle 4 and:
complete remission (CR)/partial remission (PR) - complete 2 more cycles of therapy OR
consolidation radiation therapy per treating physician.
stable disease (SD)/progressive disease (PD) - salvage therapy off study.
6, subject receives Rituximab in outpatient infusion facility.
