PALYNZIQ Co-Pay Assistance Program Patient Guide: How to Get PALYNZIQ at Low or No Cost

PALYNZIQ (pegvaliase-pqpz) is an injectable enzyme therapy approved by the FDA to help lower blood phenylalanine (Phe) levels in adults and adolescents aged 12 and older with phenylketonuria (PKU), a rare genetic disorder that affects how the body processes protein.[8][9] The PALYNZIQ Co-Pay Assistance Program from BioMarin Pharmaceutical Inc. helps eligible, commercially insured patients pay as little as $0 out-of-pocket for PALYNZIQ and related auto-injectable epinephrine prescriptions, covering up to $18,200 per calendar year in co-pays.[1][3][6]

About PALYNZIQ and PKU

Phenylketonuria (PKU) is a lifelong condition where the body cannot break down phenylalanine (Phe), an amino acid found in protein-rich foods like meat, dairy, and grains. High Phe levels can harm the brain, causing intellectual disability, behavioral issues, and other problems if not managed.[9] Traditional PKU management relies on a strict low-Phe diet and medical foods, but many patients struggle to keep Phe levels controlled.

PALYNZIQ offers a breakthrough: it's the only FDA-approved enzyme substitution therapy for PKU. Administered as daily subcutaneous injections, it replaces the missing enzyme (phenylalanine ammonia lyase) to break down Phe outside the liver, allowing more dietary flexibility while lowering blood Phe levels. Clinical trials like PEGASUS showed statistically significant Phe reductions compared to diet alone.[8] Recently expanded to adolescents 12+, it's especially helpful for teens with family support to ensure adherence.[8]

However, PALYNZIQ carries serious risks, including anaphylaxis (a life-threatening allergic reaction). That's why it's only available through the PALYNZIQ REMS (Risk Evaluation and Mitigation Strategy) program—a restricted distribution system requiring certified prescribers, enrolled patients, and always carrying auto-injectable epinephrine.[2][5][7][9]

Who Qualifies for the Co-Pay Assistance Program?

This program is not a free drug program for uninsured patients—it's designed for those with commercial (private) insurance facing high co-pays. Key eligibility criteria include:[1][3][6][10]

• A valid PALYNZIQ prescription for an FDA-approved use (adults or adolescents 12+ with PKU).
• Commercial insurance coverage (e.g., employer plans, marketplace insurance—not government programs).
• Prescription not reimbursed (even partially) by federal/state programs like Medicare, Medicaid, VA, DoD, TRICARE, or state drug assistance.
• Not cash-paying or using coupons where insurance doesn't cover the product.

Income eligibility: Unlike many patient assistance programs, this co-pay program does not have income thresholds or Federal Poverty Level (FPL) limits. It's based purely on insurance type and prescription validity. Over 99% of participating patients paid $0 out-of-pocket, and 97% of insured patients secured coverage.[1][3]

Insurance Requirements

You must have commercial insurance prescribing PALYNZIQ. Government programs (Medicare, Medicaid, etc.) disqualify you.[1][6] BioMarin reports 82% prior authorization approval rate on first try and 97% overall coverage for insured patients.* Your BioMarin RareConnections Case Manager can help with prior authorizations.[3]

Note: PALYNZIQ requires REMS enrollment. Your doctor must certify, counsel you on anaphylaxis risks, and prescribe epinephrine.[5][7][9]

1. Get Prescribed: See a REMS-certified prescriber (complete one-time certification via PALYNZIQREMS.com). Discuss PKU control and risks.[2][9]

2. Enroll in REMS: Doctor counsels you, enrolls you in PALYNZIQ REMS, and ensures epinephrine prescription. Call 1-855-758-REMS (1-855-758-7367) for questions.[5][9]
