When it comes to venture capital, the corporate model can be considered a little less risky, Jim Sledzik, North American managing director of Saudi Aramco Energy Ventures, says on last week's episode of the Houston Innovators Podcast. Over the past decade, Saudi Aramco Energy Ventures has invested $320 million into 33 portfolio companies in the United States. Sledzik, who's worked in various energy services roles around the world before entering in to investment, explains that the corporate venture model is ideal for scaling big technology — and fast.

“When you’re using the venture model in a corporate setting, you have the company and the balance sheet behind you, which brings different benefits to companies you’re investing in,” he says. “These entrepreneurs who are looking to figure out how to deploy technology at scale becomes the real interesting item. All entrepreneurs want to grow — and they want to grow fast."

Scaling fast is risky, but big corporates — like Aramco — can help address the risks by providing a foothold in the market, a place to roll out the technology, and more. Click here to stream the episode and read more.

Throughout her career, Arti Bhosale has seen the inefficiency and the ineffectiveness of selecting patients for clinical trials.

“Across the globe, more than 30 percent of clinical trials shut down as a result of not enrolling enough patients,” says Bhosale. “The remaining 80 percent never end up reaching their target enrollment and are shut down by the FDA.”

So, in 2020, Bhosale and her team developed Sieve Health, an AI cloud-based SaaS platform designed to automate and accelerate matching patients with clinical trials and increase access to clinical trials. Click here to read more.

Houston-based health tech startup is revolutionizing patient selection for clinical trials

working smarter

On many occasions in her early career, Dr. Arti Bhosale, co-founder and CEO of Sieve Health, found herself frustrated with having to manually sift through thousands of digital files.

The documents, each containing the medical records of a patient seeking advanced treatment through a clinical trial, were always there to review — and there were always more to read.

Despite the tediousness of prescreening, which could take years, the idea of missing a patient and not giving them the opportunity to go through a potentially life-altering trial is what kept her going. The one she didn’t read could have slipped through the cracks and potentially not given someone care they needed.

“Those stories have stayed with me,” she says. “That’s why we developed Sieve.”

When standard health care is not an option, advances in medical treatment could be offered through clinical trials. But matching patients to those trials is one of the longest standing problems in the health care industry. Now with the use of new technology as of 2018, the solution to the bottleneck may be a new automated approach.

“Across the globe, more than 30 percent of clinical trials shut down as a result of not enrolling enough patients,” says Bhosale. “The remaining 80 percent never end up reaching their target enrollment and are shut down by the FDA.”

In 2020, Bhosale and her team developed Sieve Health, an AI cloud-based SaaS platform designed to automate and accelerate matching patients with clinical trials and increase access to clinical trials.

Sieve’s main goal is to reduce the administrative burden involved in matching enrollments, which in turn will accelerate the trial execution. They provide the matching for physicians, study sponsors and research sites to enhance operations for faster enrollment of the trials.

The technology mimics but automates the traditional enrollment process — reading medical notes and reviewing in the same way a human would.

“I would have loved to use something like this when I was on the front lines,” Bhosale says, who worked in clinical research for over 12 years. “Can you imagine going through 10,000 records manually? Some of the bigger hospitals have upwards of 100,000 records and you still have to manually review those charts to make sure that the patient is eligible for the trial. That process is called prescreening. It is painful.”

Because physicians wear many hats and have many clinical efforts on their plates, research tends to fall to the bottom of the to-do list. Finding 10-20 patients can take the research team on average 15-20 months to find those people — five of which end up unenrolling, she says.

“We have designed the platform so that the magic can happen in the background, and it allows the physician and research team to get a jumpstart,” she says.” They don’t have to worry about reviewing 10,000 records — they know what their efforts are going to be and will ensure that the entire database has been scanned.”

With Sieve, the team was able to help some commercial pilot programs have a curated data pool for their trials – cutting the administrative burden and time spent searching to less than a week.

Sieve is in early-stage start up mode and the commercial platform has been rolled out. Currently, the team is conducting commercial projects with different research sites and hospitals.

“Our focus now is seeing how many providers we can connect into this,” she says. “There’s a bigger pool out there who want to participate in research but don’t know where to start. That’s where Sieve is stepping in and enabling them to do this — partnering with those and other groups in the ecosystem to bring trials to wherever the physicians and the patients are.”

Houston researcher secures $1.7M to develop drug for aggressive form of breast cancer

cancer research

A University of Houston researcher has joined a $3.2 million effort to develop a new drug designed to attack a cancer-driving protein commonly found in triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is one of the most difficult-to-treat forms of cancer and accounts for 10 percent to 15 percent of all breast cancer cases. The disease gets its name because tumors associated with it test negative for estrogen receptors, progesterone receptors and excess HER2 protein, making it difficult to target. Due to this, TNBC is often treated with general chemotherapy, which can come with negative side effects and drug resistance, according to UH.

UH College of Pharmacy research associate professor Wei Wang is developing a drug that can target the disease more specifically. The drug will target MDM2, a protein often overproduced in TNBC that also contributes to faster tumor growth.

Wang is working on a team led by Wei Li, director of the University of Tennessee Health Science Center College of Pharmacy’s Drug Discovery Center. She has received $1.7 million to support the research.

Wang and UH professor of pharmacology and toxicology Ruiwen Zhang have discovered a compound that can break down MDM2. In early laboratory models, the compound has shown the ability to shrink tumors.

Wang and Zhang will focus on understanding how the treatment works and monitoring its effectiveness in models that closely mirror human disease.

“We will study how the drug targets MDM2 and evaluate the most promising drug candidates to determine effective dosing, understand how the drug behaves in the body, compare it with existing treatments and assess early safety,” Wang said in a news release.

Li’s team at the University of Tennessee will be working on the chemistry and drug design end of the project.

“This work could lead to an entirely new class of therapies for triple-negative breast cancer,” Li added in the release. “We’re hopeful that by directly removing the MDM2 protein from cancer cells, we can help more patients respond to treatment regardless of their tumor type.”

NASA revamps Artemis moon landing program by modeling it after Apollo

To the moon

NASA is revamping its Artemis moon exploration program to make it more like the fast-paced Apollo program half a century ago, adding an extra practice flight before attempting a high-risk lunar landing with a crew in two years.

The overhaul in the flight lineup came just days after NASA’s new moon rocket returned to its hangar for more repairs, and a safety panel warned the space agency to scale back its overly ambitious goals for humanity’s first lunar landing since 1972.

Artemis II, a lunar fly-around by four astronauts, is off until at least April because of rocket problems.

The follow-up mission, Artemis III, had been targeting a landing near the moon’s south pole by another pair of astronauts in about three years. But with long gaps between flights and concern growing over the readiness of a lunar lander and moonwalking suits, NASA’s new administrator Jared Isaacman announced that mission would instead focus on launching a lunar lander into orbit around Earth in 2027 for docking practice by astronauts flying in an Orion capsule.

The new plan calls for a moon landing — potentially even two moon landings — by astronauts in 2028.

“Everybody agrees. This is the only way forward,” Isaacman said.

The hydrogen fuel leaks and helium flow problems that struck the Space Launch System rocket on the pad at NASA's Kennedy Space Center in February also plagued the first Artemis test flight without a crew in 2022.

Another three-year gap was looming between Artemis II and the moon landing by astronauts as originally envisioned, Isaacman said.

Isaacman stressed that “it should be incredibly obvious” that three years between flights is unacceptable. He'd like to get it down to one year or even less.

Isaacman, a tech billionaire who bought his own trips to orbit and performed the world’s first private spacewalk, took the helm at NASA in December.

During NASA’s storied Apollo program, he said, astronauts’ first flight to the moon was followed by two more missions before Neil Armstrong and Buzz Aldrin landed on the moon. What's more, he added, the Apollo moonshots followed one another in quick succession, just as the earlier Projects Mercury and Gemini had rapid flight rates, sometimes coming just a few months apart.

Twenty-four Apollo astronauts flew to the moon from 1968 through 1972, with 12 of them landing.

“No one at NASA forgot their history books. They knew how to do this," Isaacman said. “Now we're putting it in action.”

To pick up the pace and reduce risk, NASA will standardize its Space Launch System rockets moving forward, Isaacman said. These are the massive rockets that will launch astronauts to the moon aboard Orion capsules. At the same time, Elon Musk's SpaceX and Jeff Bezos' Blue Origin are speeding up their work on the landers needed to get the astronauts from lunar orbit down to the surface.

Isaacman said next year will see an Orion crew rendezvousing in orbit around Earth with SpaceX's Starship, Blue Origin's Blue Moon or both landers. It's similar to the methodical approach that worked so well during Apollo in the late 1960s, he noted. Apollo 8, astronauts' first flight to the moon, was followed by two more missions before Armstrong and Aldrin aimed for the lunar surface.

“We should be getting back to basics and doing what we know works,” he said.

The Aerospace Safety Advisory Panel recommended that NASA revise its objectives for Artemis III “given the demanding mission goals.” It’s urgent the space agency do that, the panel said, if the United States hopes to safely return astronauts to the moon. Isaacman said the revised Artemis flight plan addresses the panel's concerns and is supported by industry and the Trump administration.
