Company separated from Novan pre-IPO is looking to commercialize later this year

Durham-based medical device company PhotonMD – focused on light therapy – is looking to take its first product to market later this year, according to President and CEO Dr. Nicholas Medendorp Jr.

PhotonMD started in January 2016 after separating from Novan (Nasdaq: NOVN) – which is developing a treatment for acne without the use of antibiotics – prior to its initial public offering. Novan’s IPO closed in September and raised $51.9 million, before underwriters’ discounts and commissions.

Novan was focused on medical dermatology and “the light-based medical devices did not really fit that asset class,” says Medendorp. Ultimately, PhotonMD was spun out as a portfolio company of KNOW Bio, which has “additional IP assets” it is planning to take to market.

He says that PhotonMD is preparing for its 510(K) premarket submission to the U.S. Food and Drug Administration for its first product next quarter. The product will “likely be cleared in the second half of 2017,” he says and also “available to the marketplace,” later this year.

While Medendorp declined to discuss the specifics of the product at this point, he said it involves a safer form of light therapy for an aesthetic application.

Medendorp previously served as vice president of medical devices at Novan, and prior to that, served as vice president of research and development as well as vice president of operations at Cree.

F. Neal Hunter, founder and former CEO of Cree, is among Novan’s largest shareholders. He also serves as chairman of KNOW Bio.

Medendorp says that PhotonMD will be “leveraging technology for other indications” as well and that the company currently consists of eight full-time employees. We “have a hiring plan [and] we’ll likely double the size of the company in the next 12 months,” he says.

In terms of its commercialization plan and additional assets, Medendorp says PhotonMD “will be raising additional capital in the future.” He declined to comment further on funding.

The company has office space at Keystone Technology Park.
