Radient Pharmaceuticals is dedicated to saving lives and money for patients and global healthcare systems through the deployment of its FDA-cleared Onko-Sure® cancer test kit for colorectal cancer treatment and recurrence monitoring. After previously trading on NYSE Amex, the Company announced today that it is now trading on the OTC market’s highest tier, OTCQX.

In making this transition, Radient Pharmaceuticals joins a growing list of companies that have chosen to move off a U.S. exchange and onto OTCQX. In doing so, the Company and its investors will continue to benefit from a compliance-driven, full-service trading platform that is more efficient and cost-effective than a traditional exchange listing.

OTCQX distinguishes the best companies traded over-the-counter (OTC) from more than 9,000 securities traded on the OTCBB and OTC Link that are not required to meet any financial standards or undergo a qualitative review.

Spencer Grimes, Merriman Capital Managing Director, said: “We are very pleased to be partnering with Radient Pharmaceuticals on their transition to OTCQX. The decision to be quoted on the more cost effective and efficient OTCQX platform is in their shareholders’ best interest and will allow management to stay focused on their core business. I have no doubt that many more companies will be following Radient Pharmaceuticals from an exchange listing to QTCQX.”

Radient Pharmaceuticals CEO, Douglas MacLellan, commented: “In moving to OTCQX, we have chosen to continue to deliver liquidity, transparency and an efficient market for our shareholders, while reducing listing costs for our company, freeing up more time and resources to execute on our core business.”
