NCT ID NCT04533581

First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 1 time

Summary

This phase 2 study tests an oral drug called ME-401 in 61 Japanese adults with a slow-growing form of non-Hodgkin's lymphoma that has returned or not responded to at least two prior treatments. The drug is taken daily for the first two months, then on a weekly schedule. Researchers are checking how well it shrinks tumors and how safe it is.

What this could mean

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

Active substance
ME-401 (a PI3K inhibitor taken orally)
What this could lead to
If successful, this could provide a new treatment option for Japanese patients with a hard-to-treat form of lymphoma that has come back after other therapies.
What could go wrong
This is a small, early-phase study (61 people) with no comparison group. The drug may not work well enough or could cause side effects. It is also limited to Japanese patients, so results may not apply to other populations.
