Two Houston organizations announced a new collaboration in a major move for Houston’s biotech scene.

Fannin Partners and the University of Texas MD Anderson Cancer Center have teamed up to develop drugs based on Raptamer, the creation of Fannin company Radiomer Therapeutics.

“Raptamers combine antibody level affinities with desirable physical and pharmacokinetic properties, and a rapid path to clinic,” Dr. Atul Varadhachary, CEO of Radiomer Therapeutics and Fannin managing partner, Varadhachary, explained to InnovationMap in May. “We are deploying this unique platform to develop novel therapies against attractive first-in-class oncology targets.”

The pairing of Fannin and MD Anderson makes perfect sense. Researchers at the institution have already identified novel markers that they will target with both Raptamer-based drugs and radiopharmaceutical/radioligand therapies.

“MD Anderson and Fannin bring highly complementary capabilities to the identification of novel cancer targets and Raptamer-based drug discovery,” says Varadhachary in a press release. “Our collaboration will enable us to rapidly develop targeted therapeutics against novel targets, which we hope will offer hope to patients with progressive cancers.”

Early in this meeting of minds, researchers will focus on developing targeted radiopharmaceuticals — the Radiomers for which Varadhachary’s company is named — as well as targeted drug conjugates that utilize Raptamers. Raptamers are an innovative class of targeting vectors that combine a DNA oligonucleotide backbone with added peptide functionality, for oncology indications.

“We are committed to exceptional research that can help us further our understanding of cancer and develop impactful therapeutic options for patients in need,” says Timothy Heffernan, Ph.D., vice president and head of therapeutics discovery at MD Anderson. “Fannin’s Raptamer drug discovery platform represents an innovative new modality that offers the potential to enhance our portfolio of novel therapies, and we look forward to the opportunities ahead.”

Fannin and MD Anderson will design translational studies together and collaborate to select promising targets for drug discovery. This is a great deal for Fannin, which will retain commercialization rights for the assets that are developed. But MD Anderson won’t be left out; the institution is eligible to receive some payments based on the success of Radiomers and other Raptamer-based drugs developed through the collaboration.

Earlier this year, Varadhachary joined the Houston Innovators Podcast to discuss Fannin's innovation approach and contribution to medical development in Houston. Listen to the episode below.

Early-stage cancer-fighting startup raises pre-seed, launches under Houston life science leader

ready to grow

Fannin Partners has done it again. The Houston-based life science development group behind medtech companies Procyrion and Allterum Therapeutics announced yesterday that it has launched Radiomer Therapeutics. With an undisclosed amount of pre-seed funding, Radiomer joins the $242 million-strong Fannin portfolio.

Radiomer uses Fannin’s proprietary Raptamer platform to target vectors and ligands for theranostic application. The cancer-fighting technology is a targeting agent that can address serious maladies including breast, lung, colorectal, prostate, and head and neck cancers.

And with Radiomer’s launch, Fannin is moving with its trademark aggressiveness. Lead programs expected to complete Phase 0 imaging/dosimetry trial(s) in cancer patients in the first quarter of next year. Those will be closely followed by therapeutic programs.

“Raptamers combine antibody level affinities with desirable physical and pharmacokinetic properties, and a rapid path to clinic,” Dr. Atul Varadhachary, CEO of Radiomer Therapeutics and Fannin managing partner, says in a press release. “We are deploying this unique platform to develop novel therapies against attractive first-in-class oncology targets.”

Varadhachary has operated Radiomer in stealth mode since its 2023 inception. However, Raptamer has been in the company’s portfolio since 2019. The new company has been using the platform to generate data with the rights to radiopharmaceutical applications for the past year.

“Our lead programs include Radiomers targeting both well-established and first-in-class cancer targets,” adds Dr. Phil Breitfeld, Radiomer’s chief medical officer. “Our imaging/dosimetry trials are designed to provide clinical evidence of tumor targeting and biodistribution information, positioning us to rapidly initiate a therapeutic program(s) if successful.”

For over a decade, Fannin has developed and supported promising life science innovations by garnering grant funding and using its team of expert product developers to build out the technology or treatment. The life science innovation timeline is very different from a software startup's, which can get to an early prototype in less than a year.

"In biotech, to get to that minimally viable product, it can take a decade and tens of millions of dollars," Varadhachary said on the Houston Innovators Podcast earlier this year.

Houston digital health platform Koda lands strategic investment

money moves

Houston-based advance care planning platform Koda Health has added another investor to the lineup.

The company secured a strategic investment for an undisclosed amount from UPMC Enterprises, the commercialization arm of the University of Pittsburgh Medical Center. The funding is part of Koda's oversubscribed series A funding round that closed in October, according to a release.

"UPMC Enterprises’ investment is a meaningful signal, not just to Koda, but to the broader market," Dr. Desh Mohan, chief medical officer and co-founder of Koda Health, said in the news release. "It validates that health systems are ready to invest in infrastructure that makes advance care planning work the way it should: proactively, at scale, and with the human support that these conversations require. Having UPMC Enterprises as a strategic investor puts us in a unique position to prove what's possible."

Koda has raised $14 million to date, according to a representative from the company. Its series A round was led by Evidenced, with participation from Mudita Venture Partners, Techstars and the Texas Medical Center last year. At the time, the company said the funding would allow it to scale operations and expand engineering, clinical strategy and customer success. The company described the round as a "pivotal moment," as it had secured investments from influential leaders in the healthcare and venture capital space.

Koda Health, which was born out of the TMC's Biodesign Fellowship in 2020, saw major growth last year, as well, and now supports more than 1 million patients nationwide through partnerships with Cigna Healthcare, Privia Health, Guidehealth, Sentara, UPMC and Memorial Hermann Health System.

The company integrated its end-of-life care planning platform with Dallas-based Guidehealth in April 2025 and with Epic Systems in July 2025. It also won the 2025 Houston Innovation Award in the Health Tech Business category. Read more here.

New 'living pharmacy' biotech company launches out of Rice venture studio

fighting cancer

Rice University’s biotech venture studio RBL LLC has launched a new “living pharmacy” company, Duracyte, designed to make cancer treatment easier on patients.

Backed by an up to $45 million Advanced Research Projects Agency for Health (ARPA-H) award, Duracyte aims to commercialize implantable biohybrid pharmacy devices that are designed to produce therapeutic proteins inside the human body around the clock, replacing the need for regular injections and infusions for some cancer patients.

The company’s main platform is its Hybrid Advanced Molecular Manufacturing Regulator (HAMMR), a rechargeable, implantable device that can sense biological signals, monitor tumor environments and adjust therapeutic output in real time. HAMMR has wireless communication capabilities, which allow patients and clinicians to remotely monitor results through an app every five minutes and make changes to treatment plans without a hosptial visit. Additionally, the device can generate its own oxygen supply, which is key for the therapeutic cells’ survival.

“Biologic medicines such as monoclonal antibodies, cytokines and metabolic regulators already account for a significant share of modern therapeutics, but the way we deliver them today often requires frequent injections or infusions that can be demanding for patients and lead to inconsistent drug levels,” Daniel Anderson, MIT professor and co-founder of Duracyte, said in a news release. “Our vision is to enable a continuous, stable therapy by producing these medicines directly inside the body, which could improve treatment consistency, reduce side effects and ultimately transform how biologic therapies are delivered across many diseases.”

Duracyte’s first clinical trial is slated to begin by the end of 2026 and will focus on recurrent ovarian cancer. The Phase I study will build upon existing work on encapsulated cytokine pharmacy technology, and the company hopes that within a few years this treatment can reach clinical application.

The development of Duracyte is supported by ARPA-H's Targeted Hybrid Oncotherapeutic Regulation (THOR) project, which supports a multidisciplinary research consortium co-led by Omid Veiseh, a professor of bioengineering at Rice. The consortium also includes others at Rice, The University of Texas MD Anderson Cancer Center, Stanford University, Carnegie Mellon University, Northwestern University and the University of Houston, plus industry collaborators like Chicago-based CellTrans.

“What we are building is the culmination of years of progress in cell engineering, biomaterials and implantable device technology,” Veiseh added in the release. “By combining these advances with real-time sensing and adaptive drug delivery, we are working with the support of RBL to create a true ‘living pharmacy’ that can deliver continuous, precisely controlled biologic therapies and fundamentally change how these treatments reach patients.”

RBL launched in 2024 and is based out of Houston’s Texas Medical Center Helix Park. Duracyte is the third company launched by RBL, including Sentinel BioTherapeutics, a clinical-stage immunotherapy company developing localized cytokine therapies for solid tumors, and SteerBio, a regenerative medicine company targeting lymphedema.

“Duracyte exemplifies the kind of breakthrough that Houston’s ecosystem is built to produce,” Paul Wotton, managing partner of RBL LLC and co-founder of Duracyte, added in the release. “With world-class clinical infrastructure, exceptional engineering talent and initiatives like the Texas Biotech Task Force driving alignment across industry, investment and talent, this region is uniquely positioned to move the most ambitious ideas in medicine from concept to patient, faster than anywhere else.”
