Primary current-line option
- Indication
- IND-CLL-2L-VENR-MURANO
- Regimen
- Venetoclax + Rituximab (VenR), 24-month fixed-duration (MURANO schedule)
- Drugs + NSZU
- Venetoclax (DRUG-VENETOCLAX) 5-week ramp-up cycle 1: 20 → 50 → 100 → 200 → 400 mg PO daily (week 1-5); then 400 mg PO daily continuous for total 24 months from start of full dose
· PO daily, total 24 months therapy · PO ✓ NSZU covered
- Rituximab (DRUG-RITUXIMAB) 375 mg/m² (cycle 1) then 500 mg/m² (cycles 2-6) · IV day 1 of each 28-day cycle for 6 cycles total (start after venetoclax ramp completed) · IV ⚠ NSZU — not for this indication
- Allopurinol (DRUG-ALLOPURINOL) 300 mg PO daily · Start 72h before venetoclax ramp; continue ≥1 week after reaching 400 mg · PO ⚠ NSZU — not for this indication
- Supportive care
- SUP-TLS-PROPHYLAXIS, SUP-PJP-PROPHYLAXIS
- Hard contraindications
- CI-HBV-NO-PROPHYLAXIS
- Reason
- Primary current-line option selected by ALGO-CLL-2L at step 2; branch-driving red flag: RF-PRIOR-BTKI-PROGRESSION.
Why this branch was chosen
Triggers from the patient profile that fired and drove the chosen branch.
Step 2 → branch IND-CLL-2L-VENR-MURANO
- RF-PRIOR-BTKI-PROGRESSION ★ winner: Progression on covalent BTK inhibitor (ibrutinib, acalabrutinib, zanubrutinib). Triggers selection of non-covalent BTKi (pirtobrutinib), BCL2i (venetoclax-based regimens), CAR-T (lisocabtagene maraleucel, brexucabtagene autoleucel), or PI3Ki — depending on disease (CLL, MCL, WM). Resistance often driven by BTK C481S or PLCG2 mutation.

What NOT to do
Explicit prohibitive rules, each grounded in a regimen / supportive care / contraindication entity
Standard plan (IND-CLL-2L-VENR-MURANO)
- Do NOT skip the venetoclax 5-week ramp-up — fatal TLS documented.
- Do NOT prescribe with concomitant strong CYP3A4 inhibitor during ramp-up — fatal concentration increase.
- Do NOT start without HBV screening + entecavir prophylaxis if HBsAg+ or anti-HBc+ (anti-CD20 reactivation).
- Do NOT skip TLS prophylaxis (allopurinol + hydration) — especially with ALC >25K or bulky disease.
- Do NOT do ramp-up on an outpatient with high-burden disease — hospitalization with q6-8h labs required.
- Do NOT forget PJP prophylaxis on prolonged therapy.
- Do NOT use in prior BCL2i resistance — low efficacy; consider pirtobrutinib or CAR-T.
Monitoring schedule
Monitoring schedule by treatment phase
Standard plan · MON-CLL-BTKI
| Phase | Window | Tests | Checkpoints |
|---|
| baseline | Within 2 weeks before start | TEST-CBC, TEST-CMP, TEST-LFT, TEST-LDH, TEST-B2-MICROGLOBULIN, TEST-FISH-PANEL, TEST-NGS-LYMPHOID-PANEL, TEST-IMMUNOGLOBULINS, TEST-HBV-SEROLOGY, TEST-HCV-ANTIBODY, TEST-HIV-SEROLOGY, TEST-CECT-CAP, TEST-ECHO | - Confirm CLL diagnosis: CD19+ CD5+ CD23+ flow on PB ≥5K monoclonal B-cells
- Risk stratification: del(17p), TP53, IGHV mutational status, karyotype
- iwCLL treatment indication documented (if asymptomatic — defer to surveillance)
- Cardiac baseline (atrial fibrillation history, hypertension control)
- HBV status + entecavir prophylaxis if HBsAg+ or anti-HBc+ (anti-CD20 in VenO regimen)
|
| on_treatment_btki | Monthly × 3 months, then every 3 months | TEST-CBC, TEST-CMP, TEST-LFT | - ALC trend (lymphocytosis early on BTKi is expected — not progression)
- Bleeding events; major bleed → hold BTKi
- AF symptoms → ECG; if AF → cardiology + anticoagulation strategy
|
| on_treatment_veno | Per CLL14 schedule during 12-month VenO course | TEST-CBC, TEST-CMP, TEST-LFT, TEST-URIC-ACID | - TLS labs (K+, phosphate, calcium, uric acid, creatinine) per ramp-up schedule
- ANC + platelets pre each obinutuzumab dose
- Infusion reactions to obinutuzumab (especially first dose)
|
| response_assessment | After cycle 6 (VenO) or every 6 months on BTKi | TEST-CBC, TEST-CECT-CAP, TEST-FLOW-CYTOMETRY | - iwCLL response criteria (CR, PR, PR-L on BTKi, SD, PD)
- MRD assessment by flow on PB at end of VenO 12-month course
|
| follow_up | Every 3-6 months after treatment / continuously on BTKi | TEST-CBC, TEST-CMP, TEST-LFT | - Surveillance for relapse (median PFS years for both regimens)
- Watch for Richter transformation (rapid LDH rise, new B-symptoms, isolated mass) — re-biopsy
- Second primary malignancy screening
