| Rheumatoid arthritis evidence | 4 RCTs and observational studies show improved disease-related outcomes vs methotrexate alone; used with methotrexate for moderately–severely active RA (evidence supports net health benefit). |
| ANCA-associated vasculitides evidence | Three RCTs and observational studies demonstrating noninferiority/superiority versus cyclophosphamide for induction; maintenance benefit vs azathioprine with uncertainty. KDIGO 2024 recommends glucocorticoids + rituximab or cyclophosphamide for induction and rituximab for maintenance in many scenarios. |
| Pemphigus RCT | One RCT found rituximab plus short-term corticosteroids superior to long-term corticosteroids (better complete response, lower cumulative steroid dose, fewer severe AEs). |
| TTP evidence | Phase 2 trial and cohort data show lower relapse rates and improved outcomes versus historical controls; guideline (BCSH/ISTH) recommend rituximab in acute/refractory iTTP and for prophylaxis in low ADAMTS13. |
| MENTOR trial outcome (idiopathic membranous nephropathy) | MENTOR trial: rituximab noninferior and superior to cyclosporine for 24-month complete or partial remission; other RCTs (STARMEN, RI-CYCLO) provide comparative context. KDIGO 2021 recommends rituximab for MN with risk factors. |
| Neuromyelitis optica systematic review | Systematic reviews, RCT and observational data show significant reductions in relapse rate and improved EDSS with rituximab; NEMOS recommends rituximab as first-line. Evidence supports net benefit for relapse prevention refractory to first-line therapy. |
| HCV-associated cryoglobulinemic vasculitis evidence | Systematic reviews and 2 RCTs show improved outcomes with rituximab as add-on when antivirals fail or disease is severe/life-threatening. |
| Factor inhibitors in hemophilia | Systematic reviews, phase 2 trial, cohort studies report response rates ~25%-50% depending on mono- vs combination therapy; evidence shows improved net health outcome for refractory inhibitors. |
| Autoimmune hemolytic anemia evidence | Two RCTs and observational studies found higher overall response rates with rituximab in warm AIHA; evidence sufficient for improvement in net health outcome. |
| Multicentric Castleman disease evidence | Systematic reviews and cohort studies indicate rituximab improved overall survival and reduced incidence of NHL in multicentric Castleman disease. |
| ITP evidence | Systematic reviews and trials show mixed results; adult RCT failed to show benefit for second-line rituximab—evidence insufficient for routine coverage; ASH provides conditional recommendations favoring alternative sequencing. |
| Minimal change disease evidence | Pediatric RCTs and observational studies show benefit in children with frequently relapsing/steroid-dependent disease; adult evidence limited—KDIGO recommends rituximab as glucocorticoid-sparing in select pediatric cases. |
| Glucocorticoid-refractory chronic GVHD evidence | Multiple cohort studies demonstrate response with sustained improvements and steroid-sparing effects; evidence considered sufficient for meaningful net benefit. |
| KDIGO membranous nephropathy recommendation | KDIGO (2021) recommends rituximab or cyclophosphamide + alternate-month glucocorticoids for MN with risk factors; KDIGO AAV (2024) recommends rituximab for induction and maintenance in many patients. |
| Guideline—ISHLT (transplant) recommendations | ISHLT recommends rituximab for desensitization in HLA-sensitized heart transplant candidates and as part of combination treatment for ABMR (class 2a/2b, level C); routine induction not recommended. Evidence supports use in desensitization protocols. |
| BCSH/ISTH TTP guidance | BCSH recommends considering rituximab on admission with plasma exchange and corticosteroids for acute idiopathic TTP with neurologic or cardiac pathology and for refractory/relapsing disease; ISTH suggests adding rituximab to TPE and steroids (conditional). |
| ATS 2023 systemic sclerosis-ILD guidance | ATS conditionally recommends rituximab for SSc-ILD based on very low-quality evidence; timing and patient selection remain uncertain. |
| AAN / MS evidence | AAN (2018) found rituximab likely more effective than placebo for RRMS for some outcomes (moderate confidence) but insufficient for progressive MS; overall evidence for MS mixed and guideline inclusion variable. |
| Neuromyelitis Optica Study Group recommendation | NEMOS (2014) recommended rituximab as first-line (along with azathioprine) and second-line after azathioprine failure for NMO/NMOSD. |
| Key prescribing information / biosimilars updates | Prescribing information for Truxima, Ruxience, Riabni revised June 2025; policy incorporates biosimilar product positioning and step/second-line requirements. |
| Systematic reviews and meta-analyses cited | Multiple systematic reviews and meta-analyses across indications (e.g., NMO, AIHA, cryoglobulinemia, membranous nephropathy) underpin coverage determinations. Literature review through Aug 26, 2025. |
