Houston-based company is connecting the dots on patient referrals

Diagnosing doctors

When your doctor recommends that you visit another practitioner, it's only natural that you trust the suggestion. But it's one case in which your physician isn't always an expert. Married doctors Justin Bird, an orthopedic surgeon, and Terri-Ann Samuels, a specialist in female pelvic medicine and reconstructive surgery, have long noted that patients are often referred incorrectly.

No big deal, right? Just go to another doctor. But not everyone has that luxury. Bird and Samuels never intended to start their own company. But when Bird lost a patient due to faulty referrals, they knew something had to be done.

"He believes that if she hadn't been bounced around from doctor to doctor, they could have saved her life," says Chris E. Staffel, chief operating officer of Patients We Share, the app that the couple created to fix the broken aspect of the health care system.

In 2015, Bird and Samuels began their company when they were shocked to realize that such an app didn't already exist.

"They started working with physicians around the country who said, 'We really, really need this,' and they also invested in it," recounts Staffel. From those friends, they built a physician advisory board of 15 investors.

Prescribing growth
The project was accepted into Johnson & Johnson's incubator, JLABS in 2016, then TMCx's digital startup program in the spring of 2018.

"They started realizing it was gaining momentum and realized they needed to have business people on board," says Staffel.

They hired Michael Antonoff, a Rice University M.B.A., as CEO. He invited former classmate Staffel to join as COO. Having come from a background in oil and gas, Staffel jumped at the chance to try her hand in a different industry.

With new business clout behind PWS, the company is growing quickly. Currently, PWS is entering its next seed round of $2.5 million that will allow the company to pay salaries of new team members and bring some tech development in-house. Until now, the making of the app itself has been outsourced to Mobisoft Infotech, a company based in Houston and India, which has worked on many projects at the Texas Medical Center. Local Black + Grey Studio is responsible for the design.

PWS has been working with both those teams in recent months to get a prototype app ready for launch. Currently, 100 physicians around the country are part of an invite-only pilot program. Soon, Staffel hopes to allow early adopter doctors who haven't been invited to enroll in the program for free. It will likely be in 2020 that patients will start joining the community, too.

How it works
An index of all the providers on the app allows doctors to easily find practitioners in a particular specialty. But there's more to it. Detailed profiles contribute to machine learning that assures the optimal match every time. Patient reviews will also play a role.

Though referrals were the impetus for the creation of PWS, it may be even more important as a communication tool between doctors, fellow clinicians (anyone from nurse practitioners to physical therapists may be invited to join), and patients. Staffel says participants in the pilot program are already using the messaging system to compare notes on cases, even sending photos from surgery to consult on patient issues.

The app's encryption means that it's HIPAA-compliant. Patients provide permission to discuss their cases via the app. And they can be confident of the quality of care they'll receive. Likely, the app will remain largely invite-only, and everyone who joins will share their National Provider Identifier licenses to be vetted against the federal database.

Doctors will communicate directly with patients through the app, but will also share resources digitally. Instead of making copy after copy of information about post-surgical care, for instance, the physician need only press a button to share a link.

Eventually, the goal is for PWS to be used not just nationally, but internationally, not just by individuals, but by whole hospital systems. A world in which doctors can compare notes around globe could be a little safer for us all.

Houston researchers report promising first in-human trial for implantable cancer therapy

cancer breakthrough

When it comes to cancer remedies, the treatment can be as challenging for the body as its cause. But what if immunotherapy could be localized? That’s precisely what a Houston team may soon make a reality.

Rice University researchers, in partnership with MD Anderson Cancer Center, recently published their findings from the first in-human trial of an implantable cancer-fighting treatment in the journal Clinical Cancer Research. The paper details testing of AVB-001, encapsulated cells engineered to release interleukin-2 (IL-2)—a naturally occurring signaling protein that boosts immunity—in the peritoneal cavities of 14 patients. The goal is to avoid the toxicity usually experienced with less targeted treatments, as well as find a solution to IL-2s’ abbreviated half-lives.

“Traditional IL-2 therapy has shown potent antitumor activity, but its clinical use has been limited by severe side effects and delivery challenges,” Omid Veiseh, director of the Rice Biotech Launch Pad, professor of bioengineering at Rice and a senior author on the study, said in a press release. “This platform allows us to localize and sustain cytokine exposure directly where tumors reside while minimizing systemic toxicity.”

Serous ovarian carcinoma is especially well-suited to the use of AVB-001 because it tends to spread throughout the abdomen. After a minimally invasive laparoscopic procedure, patients implanted with the cells were noted to tolerate the treatment well. Half of the enrolled patients’ cancer was stabilized, with several among them reporting extended signs of benefit. No maximum tolerated dose was reached and there were no life-threatening events tied to the study.

If that sounds like less-than-earth-shaking results, this is only the beginning. The capsules were implanted for about one week because IL-2 activity drops off after that. The researchers now know that further testing should include either higher levels, repeated doses, or a combination thereof, in order to create stronger advances.

The team has already made early headway on this next step. Preclinical studies in nonhuman primates were not only tolerated well, but without added toxicity, the apes had consistent pharmacological effects.

“This is a foundational step,” Veiseh explained. “We now have evidence that the platform is safe, biologically active and potentially scalable. The next phase is optimizing dosing and exploring combination therapies to unlock its full clinical potential.”

The combination would also include a checkpoint inhibitor, which might improve AVB-001’s tumor-fighting power. “What is exciting is that we are not just delivering a drug, we are programming a microenvironment,” added Dr. Amir Jazaeri, professor of gynecologic oncology at MD Anderson, member of the Rice Biotech Launch Pad’s clinical advisory board and a senior author on the study. “This opens the door to combination strategies that could amplify immune responses in ways that have not been feasible before.”
