The XLH Network and Kyowa Kirin Launch the XLH Community Guidebook to Help People Navigate Lifelong Journey with XLH
Rare disease and oncology portfolio advancing with regulatory wins, expanded access, and strategic pipeline consolidation.

Executive Summary
- The most recent release (June 23, 2026) announces the launch of the XLH Community Guidebook, a joint initiative between Kyowa Kirin and The XLH Network.
- The guidebook is an online, evidence-based resource designed to help patients and caregivers manage X-linked hypophosphatemia (XLH) across all life stages.
- Content covers symptom management, care coordination, physical/emotional well-being, and life transitions.
- Initial development was a partnership, but full site management and future editions will transition to The XLH Network by the end of 2026.
- This is a patient advocacy and support resource launch, not a clinical, regulatory, or commercial sales update.
Material Impact
- Patient support and community resource initiatives are standard operational practices in the biopharmaceutical sector, particularly for rare disease therapies.
- The guidebook does not directly impact revenue, pricing, reimbursement, or clinical trial outcomes.
- Indirectly, it supports patient adherence, brand loyalty, and potentially aids market penetration for CRYSVITA (burosumab), which was recently expanded with new dosing options and Canadian public reimbursement.
- No financial metrics, sales data, or market share figures are provided to quantify commercial impact.
- The initiative is expected, incremental, and aligns with standard post-approval market access strategies.
