*The Co-pay Program (“Program”) is valid ONLY for patients with commercial (private or non-governmental) insurance who have a valid prescription for a Food and Drug Administration (FDA)-approved indication of a Genentech medicine. The Program is not available to patients whose prescriptions are reimbursed under any federal, state, or government-funded insurance programs (included but not limited to Medicare, Medicare Advantage, Medigap, Medicaid, TRICARE, Department of Defense, or Veterans Affairs Programs) or where prohibited by law or by the patient's health insurance provider. If at any time a patient begins receiving prescription drug coverage under any such federal, state or government-funded healthcare programs, the patient will no longer be eligible for the Program.
Under the Program, the patient may be required to pay a co-pay. The final amount owed by a patient may be as little as $0 for the Genentech medicine (see Program specific details available at the Program website). The total patient out-of-pocket cost is dependent on the patient’s health insurance plan. The Program assists with the cost of the Genentech medicine only. It does not assist with the cost of other medicines, procedures or office visit fees. After reaching the maximum annual Program benefit amount, the patient will be responsible for all remaining out-of-pocket expenses. The Program benefit amount cannot exceed the patient’s out-of-pocket expenses for the Genentech medicine.
All participants are responsible for reporting the receipt of all Program benefits as required by any insurer or by law. The Program is only valid in the United States and U.S. Territories, is void where prohibited by law and shall follow state restrictions in relation to AB-rated generic equivalents (e.g., MA, CA) where applicable. No party may seek reimbursement for all or any part of the benefit received through the Program. The value of the Program is intended exclusively for the benefit of the patient. The funds made available through the Program may only be used to reduce the out-of-pocket costs for the patient enrolled in the Program. The Program is not intended for the benefit of third parties, including without limitation third party payers, pharmacy benefit managers, or their agents. If Genentech determines that a third party has implemented a program that adjusts patient cost-sharing obligations based on the availability of support under the Program and/or excludes the assistance provided under the Program from counting towards the patient’s deductible or out-of-pocket cost limitations, Genentech may impose a per fill cap on the cost-sharing assistance available under the Program. Submission of true and accurate information is a requirement for eligibility and Genentech reserves the right to disqualify patients who do not comply with Genentech Program Terms and Conditions. Genentech reserves the right to rescind, revoke or amend the Program without notice at any time.
Additional terms and conditions apply. Please visit the Co-pay Program website for the full list of Terms and Conditions.
†Genentech provides coverage and reimbursement services to patients to help them understand benefits, coverage, and reimbursement. Genentech provides these services to patients only after a healthcare provider has prescribed a Genentech product.
‡Complete remission at Week 104, defined as UPCR ≤0.3 g/g (24-hr collection) with a stable eGFR (≥85% of baseline), and no intercurrent events (escape therapy, treatment failure, or early study withdrawal).1,2
§Partial remission is defined as ≥50% reduction in UPCR vs baseline, UPCR >0.3 to ≤3.5 g/g, with a stable eGFR (≥85% of baseline), and no intercurrent events (escape therapy, treatment failure, or early study withdrawal).1,2
CI=confidence interval; eGFR=estimated glomerular filtration rate; UPCR=urine protein-to-creatinine ratio.
Primary membranous nephropathy, also known as MN, is an autoimmune glomerular disease and a leading cause of nephrotic syndrome in adults. In most cases, dysregulated B cells produce anti-phospholipase A2 receptor, or anti-PLA2R, antibodies. This can lead to immune complex deposits that disrupt the kidney’s filtration barrier and cause proteinuria, hypoalbuminemia, edema, and hyperlipidemia. The clinical course may range from spontaneous remission to progressive kidney function decline.
GAZYVA® (obinutuzumab) is indicated for the treatment of adult patients with primary membranous nephropathy at risk of disease progression, to induce remission of proteinuria. GAZYVA is a type II, humanized anti-CD20 monoclonal antibody designed to bind to CD20 on pre-B and mature B lymphocytes. It is engineered for higher Fc gamma receptor III binding affinity. Based on preclinical data, GAZYVA induces greater direct B-cell death, antibody-dependent cellular cytotoxicity, and antibody-dependent cellular phagocytosis compared with type I anti-CD20 antibodies.
MAJESTY was a Phase III, randomized, controlled, open-label, multicenter study evaluating GAZYVA versus tacrolimus in adults with biopsy-confirmed MN and persistent proteinuria despite best supportive care. The primary endpoint was complete remission of proteinuria while maintaining kidney function at Week 104, defined as UPCR ≤0.3 g/g (24-hr collection) with a stable eGFR (≥85% of baseline), and no intercurrent events (escape therapy, treatment failure, or early study withdrawal).
GAZYVA is administered as an intravenous infusion according to the approved dosing schedule. Premedication is required before each infusion. GAZYVA should be administered by a healthcare professional with appropriate medical support to manage severe infusion-related reactions. Blood counts should be monitored regularly.
GAZYVA carries Boxed Warnings for hepatitis B virus reactivation and progressive multifocal leukoencephalopathy. Additional risks include infusion-related reactions, hypersensitivity reactions, tumor lysis syndrome, serious and fatal infections, neutropenia, thrombocytopenia, and disseminated intravascular coagulation.
