Alvotech announces resubmission of U.S. Biologics License Applications for AVT05, a proposed biosimilar to Simponi® and Simponi Aria®, and AVT06, a proposed biosimilar to Eylea®

REYKJAVIK, Iceland, June 4, 2026 - Alvotech (NASDAQ: ALVO; ALVO-SDB), a global biotechnology company specializing in the development and manufacture of biosimilar medicines for patients worldwide, today announced the resubmission to the U.S. Food and Drug Administration (FDA) of Biologics License Applications (BLAs) for AVT05, a proposed biosimilar to Simponi® and Simponi Aria® (golimumab), and AVT06, a proposed biosimilar to Eylea® (aflibercept) 2 mg.

Under a partnership with Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA), Alvotech is responsible for the development and manufacturing of AVT05 and AVT06, while Teva is responsible for commercialization.

The resubmissions follow the submission of Alvotech’s response to the FDA’s Post-Application Action Letter (PAAL) related to the company’s Reykjavik manufacturing facility. In addition, the company has submitted responses to observations from a routine cGMP surveillance FDA inspection at the facility, completed in May 2026, and has continued to strengthen its quality systems and manufacturing operations as part of its ongoing enhancement program.

The company expects the FDA to conduct a six-month review of the resubmitted applications, consistent with the applicable regulatory timelines.

AVT03, Alvotech’s proposed biosimilar to Prolia® and Xgeva® (denosumab), is partnered with Dr. Reddy’s Laboratories Ltd. which, as applicant, is responsible for the U.S. regulatory submission.

“These resubmissions represent an important milestone following extensive work across our manufacturing and quality organization,” said Lisa Graver, Chief Executive Officer of Alvotech. “We have worked closely with the FDA throughout this process, including responding to the agency’s Post-Application Action Letter and supporting a routine inspection of our Reykjavik facility in May. As previously disclosed, we believe the outcome of the recent inspection demonstrated the strong cGMP fundamentals of the site and the robustness of the improvements implemented since last year. We remain focused on execution, operational discipline and bringing high-quality biosimilars to patients worldwide.”

AVT05 is a proposed biosimilar to Simponi® and Simponi Aria® (golimumab), biologic medicines used to treat a variety of chronic inflammatory conditions. AVT06 is a proposed biosimilar to Eylea® (aflibercept) 2 mg, a biologic medicine used to treat several serious retinal disorders, including conditions that may lead to vision loss or blindness.
