ADC Therapeutics SA (NYSE: ADCT), a commercial-stage biotechnology company improving the lives of those affected by cancer with its next-generation, targeted antibody drug conjugates (ADCs) for patients with hematologic malignancies and solid tumors, announced today that a permanent J-code, J9359, has been issued for ZYNLONTA® by the U.S. Centers for Medicare & Medicaid Services (CMS) effective as of April 1, 2022.

“As we expand our U.S. ZYNLONTA business from the academic institutions and early adopting community networks into an increasing number of community accounts, our permanent J-code will offer accounts predictability in terms of reimbursement,” said Jennifer Herron, Chief Commercial Officer of ADC Therapeutics. “The permanent J-code for ZYNLONTA will improve access for patients and will simplify the reimbursement process for treating physicians and their staff.”

J-codes are permanent reimbursement codes used by commercial insurance plans, Medicare, Medicare Advantage, and other government payers for Medicare Part B injectable drugs like ZYNLONTA that are administered by a physician. Claims submission and documentation are simplified with a permanent J-code, facilitating and streamlining the billing and reimbursement process.

The permanent J-code for ZYNLONTA, J9359 (Injection, loncastuximab tesirine-lpyl, 0.075 mg), took effect April 1, 2022. The permanent J-code is also published online on the CMS website here.

About ZYNLONTA® (loncastuximab tesirine-lpyl)

ZYNLONTA® is a CD19-directed antibody drug conjugate (ADC). Once bound to a CD19-expressing cell, ZYNLONTA is internalized by the cell, where enzymes release a pyrrolobenzodiazepine (PBD) payload. The potent payload binds to DNA minor groove with little distortion, remaining less visible to DNA repair mechanisms. This ultimately results in cell cycle arrest and tumor cell death.

The U.S. Food and Drug Administration (FDA) has approved ZYNLONTA (loncastuximab tesirine-lpyl) for the treatment of adult patients with relapsed or refractory (r/r) large B-cell lymphoma after two or more lines of systemic therapy, including DLBCL not otherwise specified, DLBCL arising from low-grade lymphoma and also high-grade B-cell lymphoma. The trial included a broad spectrum of heavily pre-treated patients (median three prior lines of therapy) with difficult-to-treat disease, including patients who did not respond to first-line therapy, patients refractory to all prior lines of therapy, patients with double/triple hit genetics and patients who had stem cell transplant and CAR-T therapy prior to their treatment with ZYNLONTA. This indication is approved by the FDA under accelerated approval based on overall response rate and continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

ZYNLONTA is also being evaluated as a therapeutic option in combination studies in other B-cell malignancies and earlier lines of therapy.
