An emerging biotech company in Houston has closed its series A with outsized success.

March Biosciences' oversubscribed raise brought in $28.4 million of financing with Mission BioCapital and 4BIO Capital leading the pack of investors. The company has now raised more than $51 million in total.

Last year, March Biosciences announced its strategic alliance with CTMC (Cell Therapy Manufacturing Center), a joint venture between MD Anderson Cancer Center and National Resilience. CEO Sarah Hein met her co-founder, Max Mamonkin, at the TMC Accelerator for Cancer Therapeutics. Along with fellow co-founder Malcolm Brenner, March Biosciences launched from the Center for Cell and Gene Therapy (Baylor College of Medicine, Houston Methodist Hospital and Texas Children’s Hospital). Its goal is to fight cancers that have been unresponsive to existing immunotherapies using its lead asset, MB-105.

An autologous CD5-targeted CAR-T cell therapy, MB-105 is currently in phase-1 trials in patients with refractory T-cell lymphoma and leukemia. The treatment is showing signs of being both safe and effective, meriting a phase-2 trial that will begin early next year. The funds raised from the series A will help to finance the Phase 2 clinical development of MB-105 to expand on the existing data with optimized manufacturing processes.

“This oversubscribed financing enables us to advance our first-in-class CAR-T therapy, MB-105, into a Phase 2 trial for T-cell lymphoma – an indication with an exceptionally poor prognosis and few treatment options,” says Hein. “With the support and confidence of our investors, we are not only advancing our lead program but also expanding our pipeline, underscoring our commitment to delivering best-in-class therapies to patients that can change the treatment paradigm for these challenging cancers.”

But that’s not the only exciting news that Hein and her associates have to report. March Biosciences has recently partnered with cell therapy venture studio, Volnay Therapeutics. Led by highly experienced cell therapy development veterans, the March Biosciences team will work to develop a scalable manufacturing process for MB-105 that will lead to commercialization. Volnay co-founder and CEO Stefan Wildt, who held key R&D leadership positions in cell and gene therapy units at Novartis and Takeda, has also joined the board of March Biosciences. The board of directors is also welcoming Cassidy Blundell of Mission BioCapital and Owen Smith of 4BIO Capital.

“The team at March Biosciences is leveraging powerful science and promising clinical data to tackle cancers with significant unmet need,” says Blundell, a partner at Mission BioCapital. “We're excited to support their journey and believe their focused approach with MB-105 could lead to significant breakthroughs in the CAR-T space.”

The Houston-born company, which is a finalist for the 2024 Houston Innovation Awards, continues to accelerate quickly, in part thanks to its home base. After all, existing local investors like TMC Venture Fund also participated in the new raise. As Hein said last year, “Working with partners here in Houston, we have all the pieces and the community rises to the occasion to support you.”

Houston health tech startup scores $2.5M SBIR grant to advance unique cell therapy AI technology

fresh funding

A Houston biotech company just announced a new award of $2.5 million.

CellChorus, a spinoff of the Single Cell Lab at the University of Houston, announced the fresh funding, which comes from an SBIR (Small Business Innovation Research) grant from the National Institute of Health (NIH) through its National Center for Advancing Translational Sciences (NCATS).

CellChorus is the business behind a technology called TIMING, which stands for Time-lapse Imaging Microscopy In Nanowell Grids. It’s a visualization AI program that helps scientists to better understand the functioning of cells, including their activation, killing and movement. This more in-depth knowledge of immune cells could be instrumental in developing novel therapies in countless disorders, including cancers and infectious diseases.

“While many cell therapies have been approved and are in development, the industry needs an integrated analytical platform that provides a matrix of functional readouts, including cell phenotype and metabolism on the same cells over time,” Rebecca Berdeaux, vice president of science at CellChorus, says in a press release. “We are grateful to NCATS for its support of the development of application-specific kits that apply dynamic, functional single-cell analysis of immune cell phenotype and function. The product we will develop will increase the impact of these therapies to improve the lives of patients.”

A two-year, $2.1 million Phase II grant will begin after the company achieves predetermined milestones under a $350,000 Phase I grant that is currently taking place. As Berdeaux explained, the funds will be used to develop TIMING kits which will manufacture analytics that provide end-users with rapid, specific and predictive results to accelerate translational research and the development and manufacture of more effective cell therapies.

TIMING is more than a great idea whose time has yet to come. It has already been proven in great depth. In fact, last June, CellChorus CEO Daniel Meyer told InnovationMap that he was initially attracted to the technology because it was “very well validated.” At the time, CellChorus had just announced a $2.3 million SBIR Fast-Track grant from the National Institute of General Medical Sciences. The company also went on to win an award in the Life Science category of the 2023 Houston Innovation Awards.

That confirmation of success comes from more than 200 peer-reviewed papers that describe myriad cell types and types of therapy, all of which used data from TIMING assays. TIMING data has benefited industry leaders in everything from research and clinical development to manufacturing. With the new grant, TIMING will become more widely available to scientists making important discoveries relating to the inner workings of the cells that drive our immunity.

Seattle biotech co. to move to Houston thanks to $13.3M grant from Texas organization

CPRIT funding spotted

A biotech company has landed a more than $13 million grant from the Cancer Prevention and Research Institute of Texas.

The nearly $13.3 million grant given to OncoResponse — which is relocating from Seattle to Houston, according to CPRIT's news release — will help the company develop fully human monoclonal antibodies for treatment of cancer that otherwise would not respond to immunotherapy. OncoResponse already has a partnership with MD Anderson Cancer Center, which is one of the company’s investors.

“We are thrilled to receive this recognition from CPRIT in supporting the potential of our immunotherapy candidate OR502. We greatly appreciate the additional support from our investors as we continue to make significant progress with our drug development efforts advancing immunotherapies derived from clues of Elite Responders,” says Clifford Stocks, CEO of OncoResponse, in a news release.

Aside from the grant, OncoResponse just hauled in $14 million from existing investors in a round led by RiverVest Venture Partners. Other participants in the series D round include Venture Partners, Canaan Partners, 3B Future Health Fund, Bering Capital, Takeda Ventures, and InterVest Capital Partners.

To date, OncoResponse has raised more than $180 million, according to market research company CB Insights.

A representative of OncoResponse couldn’t be reached for comment about the company’s relocation to Houston.

MD Anderson and Seattle-based Theraclone Sciences launched OncoResponse in 2015. Rice University was among the inaugural investors.

OncoResponse’s OR2805 immunotherapy product is being evaluated in a Phase 1 clinical trial. It’s the company’s leading immunotherapy candidate. OncoResponse is also working on OR502, an antibody being prepared for investigational and clinical studies.

“The modern treatment of cancer activates the body’s own immune system to attack cancer,” OncoResponse says in a summary posted on the website of the Cancer Prevention and Research Institute of Texas (CPRIT).

“These treatments, called immunotherapy, may not be successful if the cancer can recruit bad-acting cells, such as tumor associated macrophages, or TAMs, that create barriers preventing immunotherapies from activating the body’s own defenses against the cancer. To find drugs that may help counteract these TAMs, OncoResponse looked to patients who had responded very well to immunotherapy to see if their bodies made factors to block TAMs and helped them fight their cancers.”

OncoResponse’s OR502 prevents TAMs from shutting down the body’s response to cancer, thus restoring tumor-killing immune activity, CPRIT explains.

In addition to OncoResponse, recent CPRIT grant recipients from the Houston area are:

  • Houston-based 7 Hills Pharma, $13,439,001. The company is working on immunotherapies for treatment of cancer and prevention of infectious diseases.
  • Houston-based Allterum Therapeutics, $11,721,150. The company is coming up with an antibody for treatment of patients with acute lymphoblastic leukemia. This type of cancer affects blood and bone marrow.
  • Houston-based Cell Therapy Manufacturing Center, $9.1 million. The center is a joint venture between National Resilience and MD Anderson Cancer Center that is developing cell therapy manufacturing technologies to support biotech partnerships.
  • Houston-based Pulmotect, $8,851,165. The company’s PUL-042 product is aimed at treating and preventing respiratory complications in cancer patients.
  • Cancer researcher Michael King, $6 million. The grant helped lure King to Rice from Nashville’s Vanderbilt University, where he’s been the chair of biomedical engineering. King’s lab at Vanderbilt has been testing therapies for metastatic breast cancer and prostate cancer.
  • Missouri City-based OmniNano Pharmaceuticals, $2,711,437. The pharmatech company is working on two drugs for treatment of solid tumors in patients with pancreatic cancer.

“Texas is unique because of CPRIT’s ability to invest in cutting-edge research when private capital is scarce. This is yet another way Texas is leading the nation in the fight against cancer,” Wayne Roberts, CEO of CPRIT, says in a news release.

Axiom Space-tested cancer drug advances to clinical trials

mission critical

A cancer-fighting drug tested aboard several Axiom Space missions is moving forward to clinical trials.

Rebecsinib, which targets a cancer cloning and immune evasion gene, ADAR1, has received FDA approval to enter clinical trials under active Investigational New Drug (IND) status, according to a news release. The drug was tested aboard Axiom Mission 2 (Ax-2) and Axiom Mission 3 (Ax-3). It was developed by Aspera Biomedicine, led by Dr. Catriona Jamieson, director of the UC San Diego Sanford Stem Cell Institute (SSCI).

The San Diego-based Aspera team and Houston-based Axiom partnered to allow Rebecsinib to be tested in microgravity. Tumors have been shown to grow more rapidly in microgravity and even mimic how aggressive cancers can develop in patients.

“In terms of tumor growth, we see a doubling in growth of these little mini-tumors in just 10 days,” Jamieson explained in the release.

Rebecsinib took part in the patient-derived tumor organoid testing aboard the International Space Station. Similar testing is planned to continue on Axiom Station, the company's commercial space station that's currently under development.

Additionally, the drug will be tested aboard Ax-4 under its active IND status, which was targeted to launch June 25.

“We anticipate that this monumental mission will inform the expanded development of the first ADAR1 inhibitory cancer stem cell targeting drug for a broad array of cancers," Jamieson added.

According to Axiom, the milestone represents the potential for commercial space collaborations.

“We’re proud to work with Aspera Biomedicines and the UC San Diego Sanford Stem Cell Institute, as together we have achieved a historic milestone, and we’re even more excited for what’s to come,” Tejpaul Bhatia, the new CEO of Axiom Space, said in the release. “This is how we crack the code of the space economy – uniting public and private partners to turn microgravity into a launchpad for breakthroughs.”
