PTx Assist Patient Assistance Program Guide: How to Get Bizengri (zenocutuzumab-zbco) at Low or No Cost

Bizengri (zenocutuzumab-zbco) is a prescription medication offered through Partner Therapeutics' PTx Assist Patient Assistance Program (PAP), which provides free or low-cost access for eligible patients who are uninsured or have limited insurance coverage[2][4]. This guide explains eligibility, application steps, and support options to help you access this important treatment.

About Bizengri (zenocutuzumab-zbco)

Bizengri is a bispecific antibody used to treat certain cancers, such as NRG1 fusion-positive tumors in non-small cell lung cancer (NSCLC) and pancreatic ductal adenocarcinoma (PDAC)[5]. Administered via intravenous infusion, it targets HER2 and HER3 proteins to block tumor growth signals. Partner Therapeutics, a biopharmaceutical company focused on cancer therapies, markets Bizengri through its PTx Assist services, supporting patients throughout treatment[3][5].

This program is part of Partner Therapeutics' commitment to patients with serious diseases, offering medication at no cost for those who qualify[1][2]. Always consult your doctor to confirm if Bizengri is right for your condition.

Who Qualifies for the Program?

The PTx Assist PAP is designed for patients facing financial barriers to treatment[4]. Key qualifications include:

• Uninsured or underinsured: Ideal for those without prescription coverage or with high out-of-pocket costs[2][4].
• U.S. residency: Program serves patients in the United States[1].
• Valid prescription: Must be prescribed by a licensed healthcare provider[7].
• Financial need: Eligibility based on income, household size, and insurance status—call for personalized assessment[2].

Patients with Medicare, Medicaid, or commercial insurance may still qualify if coverage is limited or copays are unaffordable[4]. The program does not publicly list strict income thresholds online; contact PTx Assist at 1-877-353-8546 for details[2][9].

Income Eligibility Breakdown

Specific income thresholds (as a percentage of the Federal Poverty Level, FPL) are not detailed publicly and vary by case[2]. Typically, PAPs like this cover households at or below 400-500% FPL, but confirmation is required via phone[1]. Use the table below for general guidance—exact eligibility depends on your situation.

Table based on 2026 FPL estimates; program may use different criteria. Assets, expenses, and insurance factor in[1][2].

Insurance Requirements

• No insurance required: Uninsured patients are priority[4].
• Limited coverage accepted: If your plan doesn't cover Bizengri fully, the program bridges the gap[2].
• Government insurance: Medicare Part D or Medicaid patients may qualify for copay assistance or free drug if out-of-pocket exceeds limits[4].
• Employer plans: Submit proof of denial or high copays[7].

Pro tip: Gather insurance cards, Explanation of Benefits (EOB), and denial letters before applying[1].
