Dose precision is the product.

Children with rare diseases are often dosed from adult tablets cut at home. One validated formulation prints every weight band at ±1%.

Printed, weight-banded, taste-masked chewables

A new strength, or a titration series as the child grows, is a file change, not a factory change.

Undisclosed compound · rare pediatric disease

Serious, early-onset and dosed by body weight: a dose that must change as the child grows
No FDA-approved product exists; today's treatment is improvised
Printed weight-banded, taste-masked chewable in place of hand-measured doses
Designation applications draw on published literature; an objective endpoint supports a compact, single-arm program

PharmaTher will announce the designation applications once filed. Further candidates are screened behind it.

Next: ultra-rare diseases

Too few patients for a production line. Exactly right for printing.

Ultra-rare diseases affect fewer than 1 in 50,000 people, or roughly 7,000 or fewer in the U.S. These patients may need only a few thousand doses a year, often in weight-based strengths.

PharmaTher is evaluating ultra-rare diseases with no FDA-approved treatment where a printed, precisely dosed product could become the first approved therapy, using the same regulatory approach as its lead program.
