About This Medication

# Genentech Patient Foundation Patient Guide: How to Get LUNSUMIO (mosunetuzumab) at Low or No Cost LUNSUMIO (mosunetuzumab) is a prescription medication used to treat certain types of relapsed or refractory follicular lymphoma in adults who have received at least two prior systemic therapies. The **Genentech Patient Foundation** offers this important drug at no cost to eligible patients facing financial barriers, whether uninsured or insured with high out-of-pocket costs. ## About LUNSUMIO (mosunetuzumab) LUNSUMIO is a bispecific antibody therapy that works by engaging the body's immune system to target and destroy cancer cells expressing CD20, a protein found on B-cells. It's administered via intravenous infusion, typically starting with step-up doses to manage potential side effects like cytokine release syndrome (CRS), followed by full doses every 28 days. Common side effects include fatigue, headache, musculoskeletal pain, and infusion reactions. Always consult your healthcare provider for personalized advice on treatment, risks, and monitoring. This guide explains how the Genentech Patient Foundation can help you access LUNSUMIO without the high costs, which can exceed tens of thousands of dollars per cycle. The program provides free medication for up to one year, with continued access as long as you remain eligible—no re-enrollment needed.[8][5] ## Who Qualifies? The Genentech Patient Foundation supports U.S. patients (treated by a U.S.-licensed physician) who meet specific financial and insurance criteria. You may qualify if you fall into one of these groups:[5][9] - **Uninsured patients** with household income under $150,000 (some exceptions apply). - **Insured patients** whose out-of-pocket maximum exceeds 7.5% of their yearly household income, based on household size. - **Underinsured patients** unable to afford cost-sharing requirements for their Genentech medicine. No citizenship or immigration information is required. The program does not cover patients enrolled in government programs like Medicare or Medicaid as primary coverage for the medication, but commercially insured or underinsured patients with financial concerns may qualify.[5][1] ## Income Eligibility Breakdown Eligibility hinges on household income and size, with a cap at $150,000 annually for uninsured patients.
