About us

Mark Summers set out on his journey to solve the problem of slow clinical trial enrollment by founding ThreeWire. As trailblazers in the field of patient recruitment, the investment community initially had its doubts, and while most said no, the company moved forward with the support of a few close investors. Over time, Natan Paz joined to expand the company internationally, beating the odds (and those initial doubts) and in the end, fundamentally changing the clinical trial market, becoming an industry leader, operating in over 40 countries worldwide and creating billions of dollars in value. Today, the field of patient recruitment attracts mainstream investments and acquisitions.

It all started in 1999…

While one problem was being solved, Mark and Natan recognized another issue. Patients came home after treatments in the hospitals and had to deal with debilitating side effects, questions about dosing, and difficulty reaching their care teams. At the same time, care teams were becoming overwhelmed by patient load and having to manage processes from afar. It was clear that the process of at-home cancer medication treatment was broken.

With experience trailblazing new fields and supported by the same investors, Dosentrx and ReX were born. Alan Paz joined the team as founder and CTO to build the platform. Similar to ThreeWire, Dosentrx works together with data, service technology, pharmaceutical companies, doctors, and pharmacists to ensure that home treatment is effective.
