Future Outlook

Jazz Pharmaceuticals is focused on deepening and expanding its commitment to rare diseases, leveraging its expertise to build $1B+ franchises and strategically expand its portfolio. Key future milestones include the sBLA submission for zanidatamab in 1L GEA in 1H26 with potential approval and launch in late 2026, continued indication expansion for zanidatamab, and top-line data readouts for EmpowHER-BC-303 and the Modeyso ACTION trial in late 2027/early 2028 and late 2026/early 2027, respectively. The company also plans a Phase 3 NDA filing for Dordaviprone capsule formulation in mid-2027.

Management Comments

• "The results of the HERIZON-GEA-01 study are practice-changing. In addition to the PFS and OS benefits, the remarkably long duration of response and consistent benefit across relevant subgroups, including PD-L1 positive and negative tumors, strongly suggest that zanidatamab plus chemotherapy, with or without tislelizumab, should become the new standard of care for patients with HER2+ first-line locally advanced unresectable or metastatic GEA." (Dr. Geoffrey Ku, Associate Attending Physician on the Gastrointestinal Oncology Service in the Department of Medicine at Memorial Sloan Kettering Cancer Center and study co-author, quoted by Jazz Pharmaceuticals).
• The company's goal is to become the HER2-targeted therapy of choice and cornerstone of future growth for Jazz.

Industry Context

Jazz Pharmaceuticals is strategically refining its focus on the rare disease market, which is characterized by high unmet medical needs, smaller patient populations, concentrated call points, and lower competitive intensity. This focus aligns with a broader industry trend where pharmaceutical companies seek to capitalize on the premium pricing and specialized market access opportunities often available for orphan drugs and rare disease treatments. The company's success in establishing multiple $1B+ franchises in rare sleep, epilepsy, and oncology demonstrates its capability to compete effectively in these specialized segments, leveraging its R&D and commercial expertise. The development of zanidatamab for HER2+ GEA positions Jazz to potentially set a new standard of care in a significant oncology indication, reflecting the industry's drive for highly differentiated, targeted therapies.

Comparison to Industry Standards

• Zanidatamab's HERIZON-GEA-01 study results are described as "practice-changing" and suggesting it "should become the new standard of care" for patients with HER2+ first-line locally advanced unresectable or metastatic GEA, indicating a potential leadership position in this specific oncology segment.
• Epidiolex is highlighted as the "standard of care" in Lennox-Gastaut syndrome (LGS), Dravet syndrome (DS), and Tuberous Sclerosis Complex (TSC), demonstrating its established market leadership in rare epilepsies.
• Xywav is noted as the "only approved drug to treat IH" (Idiopathic Hypersomnia), positioning it as a unique and leading treatment option in its therapeutic area.
• The company's achievement of three $1B+ franchises (rare sleep, rare epilepsy, rare oncology) positions it among a select group of pharmaceutical companies with diversified, high-performing rare disease portfolios, comparable to other specialized biopharma leaders.
