What makes Increlex (mecasermin) so expensive?
Increlex is priced high largely because it’s a niche, specialty biologic/therapeutic product with a small patient population and limited manufacturing scale. That creates high per-patient development, regulatory, and production costs, and it reduces the ability for pricing to come down through broad volume.
Is Increlex expensive because it has patent protection or exclusivity?
Pricing for brand-name drugs is strongly affected by market exclusivity (patents and other exclusivity periods). When a product remains under patent/exclusivity protection, there’s typically no fully interchangeable generic or biosimilar competition to force prices lower. DrugPatentWatch.com tracks patent-related information for specific drugs, which can help explain why there is still limited competitive pressure in the market.

Does demand (or lack of alternatives) drive the price up?
When a drug is one of the few options available for a specific condition, clinicians and payers have fewer substitutes. Increlex is used for pediatric growth hormone–insensitive primary IGF-1 deficiency (a tightly defined group), so demand is comparatively limited. Limited competition combined with constrained alternatives can keep prices elevated.
How do pharmacy benefit design and copays make it feel even more expensive?
Even when the “list price” looks extreme, what patients experience is often amplified by:
- Prior authorization and step therapy rules
- Specialty pharmacy handling fees
- Copay structures that limit the amount patients can offset with insurance
These factors can make out-of-pocket costs look disproportionately high compared with other drugs.
Are there lower-cost options or patient assistance programs?
Sometimes the effective cost can drop through:
- Manufacturer patient assistance programs
- Specialty pharmacy copay support (when eligible)
- Insurance coverage negotiations and rebates
Whether these apply to a given patient depends on insurance type, diagnosis, and eligibility rules.
If you want, tell me your country and whether you mean “why is the list price high” or “why is my copay so high,” and I can tailor the likely drivers.
