Artificial intelligence in the health care setting has a lot of potential, and one Houston institution is looking into one particular use.

Researchers at Baylor College of Medicine’s Human Genome Sequencing Center have trained an AI assistant to explain genetic test results to patients. According to findings published in the Journal of the American Medical Informatics Association (JAMIA), the team has developed generative AI to understand and interpret genetic tests. They have also tested its accuracy against Open AI’s ChatGPT 3.5.

“We created a chatbot that can provide guidance on general pharmacogenomic testing, dosage implications, and the side effects of therapeutics, and address patient concerns,” explains first author Mullai Murugan in a press release. Murugan is director of software engineering and programming at the Human Genome Sequencing Center. “We see this tool as a superpowered assistant that can increase accessibility and help both physicians and patients answer questions about genetic test results.”

The initial chatbot training specifically targeted pharmacogenomic testing for statins, meaning a patient’s potential response to cholesterol-lowering drugs, as dictated by genetics.

Murugan explains why they decided to create their own chatbot in the key publication on statin pharmacogenomics was published in May 2022, four months after the training cutoff date for ChatGPT 3.5 in January 2022. Alternatively, her team’s technology uses Retrieval Augmented Generation (RAG) and was trained on the most recent guidelines.

How did the two AI assistants compare? Four experts on cardiology and pharmacogenomics rated both chatbots based on accuracy, relevancy, risk management, and language clarity, among other factors. Though the AI scored similarly on language clarity, Baylor’s chatbot scored 85 percent in accuracy and 81 percent in relevancy compared to ChatGPT’s 58 percent in accuracy and 62 percent in relevancy when asked questions from healthcare providers.

“We are working to fine-tune the chatbot to better respond to certain questions, and we want to get feedback from real patients,” Murugan says. “Based on this study, it is very clear that there is a lot of potential here.” Nonetheless, Murugan emphasized that there is much work still to be done before the program is ready for clinical applications. That includes training the chatbot to explain results in the language used by genetic counselors. Funds from the NIH’s All of Us Research Program helped to make the research possible.

German biotech co. to relocate to Houston thanks to $4.75M CPRIT grant

money moves

Armed with a $4.75 million grant from the Cancer Prevention and Research Institute of Texas, a German biotech company will relocate to Houston to work on developing a cancer medicine that fights solid tumors.

Eisbach Bio is conducting a clinical trial of its EIS-12656 therapy at Houston’s MD Anderson Cancer Center. In September, the company announced its first patient had undergone EIS-12656 treatment. EIS-12656 works by suppressing cancer-related genome reorganization generated by DNA.

The funding from the cancer institute will support the second phase of the EIS-12656 trial, focusing on homologous recombination deficiency (HRD) tumors.

“HRD occurs when a cell loses its ability to repair double-strand DNA breaks, leading to genomic alterations and instability that can contribute to cancerous tumor growth,” says the institute.

HRD is a biomarker found in most advanced stages of ovarian cancer, according to Medical News Today. DNA constantly undergoes damage and repairs. One of the repair routes is the

homologous recombination repair (HRR) system.

Genetic mutations, specifically those in the BCRA1 and BCRA1 genes, cause an estimated 10 percent of cases of ovarian cancer, says Medical News Today.

The Cancer Prevention and Research Institute of Texas (CPRIT) says the Eisbach Bio funding will bolster the company’s “transformative approach to HRD tumor therapy, positioning Texas as a hub for innovative cancer treatments while expanding clinical options for HRD patients.”

The cancer institute also handed out grants to recruit several researchers to Houston:

  • $2 million to recruit Norihiro Goto from the Massachusetts Institute of Technology to MD Anderson.
  • $2 million to recruit Xufeng Chen from New York University to MD Anderson.
  • $2 million to recruit Xiangdong Lv from MD Anderson to the University of Texas Health Science Center at Houston.

In addition, the institute awarded:

  • $9,513,569 to Houston-based Marker Therapeutics for a first-phase study to develop T cell-based immunotherapy for treatment of metastatic pancreatic cancer.
  • $2,499,990 to Lewis Foxhall of MD Anderson for a colorectal cancer screening program.
  • $1,499,997 to Abigail Zamorano of the University of Texas Health Science Center at Houston for a cervical cancer screening program.
  • $1,497,342 to Jennifer Minnix of MD Anderson for a lung cancer screening program in Northeast Texas.
  • $449,929 to Roger Zoorob of the Baylor College of Medicine for early prevention of lung cancer.

On November 20, the Cancer Prevention and Research Institute granted funding of $89 million to an array of people and organizations involved in cancer prevention and research.

West Coast innovation organization unveils new location in Houston suburb to boost Texas tech ecosystem

plugging in

Leading innovation platform Plug and Play announced the opening of its new flagship Houston-area location in Sugar Land, which is its fourth location in Texas.

Plug and Play has accelerated over 2,700 startups globally last year with corporate partners that include Dell Technologies, Daikin, Microsoft, LG Chem, Shell, and Mercedes. The company’s portfolio includes PayPal, Dropbox, LendingClub, and Course Hero, with 8 percent of the portfolio valued at over $100 million.

The deal, which facilitated by the Sugar Land Office of Economic Development and Tourism, will bring a new office for the organization to Sugar Land Town Square with leasing and hiring between December and January. The official launch is slated for the first quarter of 2025, and will feature 15 startups announced on Selection Day.

"By expanding to Sugar Land, we’re creating a space where startups can access resources, build partnerships, and scale rapidly,” VP Growth Strategy at Plug and Play Sherif Saadawi says in a news release. “This location will help fuel Texas' innovation ecosystem, providing entrepreneurs with the tools and networks they need to drive real-world impact and contribute to the state’s technological and economic growth."

Plug and Play plans to hire four full-time equivalent employees and accelerate two startup batches per year. The focus will be on “smart cities,” which include energy, health, transportation, and mobility sectors. One Sugar Land City representative will serve as a board member.

“We are excited to welcome Plug and Play to Sugar Land,” Mayor of Sugar Land Joe Zimmerma adds. “This investment will help us connect with corporate contacts and experts in startups and businesses that would take us many years to reach on our own. It allows us to create a presence, attract investments and jobs to the city, and hopefully become a base of operations for some of these high-growth companies.”

The organization originally entered the Houston market in 2019 and now has locations in Bryan/College Station, Frisco, and Cedar Park in Texas.
