Light-Activated cream could slow growth of NF1 skin tumors

NCT ID NCT02728388

First seen Jul 10, 2026 ยท Last updated Jul 10, 2026

Summary

This trial tests whether a light-activated cream (Levulan Kerastick) followed by red light therapy can slow the growth of benign skin tumors called neurofibromas in people with neurofibromatosis type 1 (NF1). About 30 participants aged 14 and older with superficial tumors on the trunk or limbs will receive either the active treatment or a placebo. The main goal is to see how long it takes for treated tumors to grow by 50% compared to untreated ones.

What this could mean

Our plain-language read of the trial. This is informational only โ€” not medical advice or a prediction.

Active substance
aminolevulinic acid (Levulan Kerastick) with red light photodynamic therapy
What this could lead to
If it works, this could offer a non-surgical way to slow or stop the growth of painful or disfiguring skin tumors in people with NF1.
What could go wrong
This is a small early-phase trial, so results may not apply to everyone. The treatment may cause skin reactions and might not shrink existing tumors.
