Exactly! This is the biology we’re building @IN8bio around. So much potential!
NEW FRONT IN THE WAR ON CANCER: THE CELLS THAT DON’T PLAY BY THE RULES Forget the T cells you know. There’s a rogue branch of the immune system - γδ T cells - and they’re not waiting for your MHC permission slip. These cells don’t need to “see” cancer the old-fashioned way. They hunt by instinct - detecting stress, mutation, and molecular chaos where αβ T cells see nothing. Think of them as the immune system’s black ops, trained to strike tumors that hide from mainstream defenses. The kicker? They can be mass-produced from healthy donors. No bespoke cell cocktails, no waiting for weakened patients to donate their own. “Off-the-shelf” soldiers, ready to deploy. Early trials show they kill tumors, boost immune memory, and even help repair damage - all without torching healthy tissue. γδ T cells could do what αβ therapies can’t: take the fight to every cancer, in every body, without the side effects that make remission feel like survival’s fine print. The next generation of immunotherapy isn’t coming from a lab - it’s been sitting in our blood all along. Source: Science, Hayday et al.

Exciting data from our Phase 1 INB-200 program presented in an oral session this weekend at ASCO2025! I heard great feedback from KOLs across the country as we try to make a real impact for these patients with GBM. Please join us on a conference call at 8:30am EDT as we review the data where median PFS for patients receiving repeated doses surpassed historical median OS for standard-of-care.
IN8bio Presents Positive Phase 1 Data of INB-200 in Newly Diagnosed GBM Demonstrating Prolonged Progression-Free Survival. Join us today, June 2nd at 8:30 am, for a company conference call to discuss the data with IN8bio management and Dr. Burt Nabors, the lead clinical investigator.

When we founded IN8bio, the idea was simple but ambitious: bring smarter, safer cell therapies to patients who need better options. Glioblastoma is one of the deadliest cancers, with virtually no progress in over two decades. Many told us not to bother because it was too hard, too small, too costly, or just because it's impossible. But for patients like Jim and their families, that’s not an acceptable answer. Jim’s inspiring story shows what’s possible when science, perseverance, and courage come together. It’s a testament to innovation, to the vision of our scientific team, and to the dedication of physicians who refuse to give up. We're still in the fight to find a path forward. Join us in a few weeks for an update at ASCO2025. We’re proud of what our team and partners have accomplished, but the fight is far from over. Patients are still waiting. This is why we do what we do.
Jim was diagnosed with glioblastoma—one of the deadliest brain cancers. Facing dismal survival rates and a standard of care that hasn’t changed in over 20 years, he joined an @In8bio trial using his immune system to fight back. Jim's alive today—he is defying the odds. Watch his story. #BrainTumorStrong #BrainTumorAwareness #GBM #BrainCancer #Immunotherapy #CancerZero @SenJohnMcCain @mbsings @NBTStweets @BrainTumourOrg @theABTA @braintumourrsch @glioblastomaorg

Exciting progress on our preclinical pipeline presented this week at AACR2025. Our lead T cell engager candidates, INB-619 (targeting CD19) and INB-633 (targeting CD33), have shown potent anti-cancer activity with some distinct advantages! They effectively eliminated cancer cells in models without the secretion of potentially harmful inflammatory signals such as IL-6 that are associated with conventional engagers and drive significant toxicities like cytokine release syndrome. We're optimistic about the potential of these candidates in the fight against cancer! #CancerZero

Thanks to @KarenJagoda for inviting me on her Empowered Patient Podcast to talk about @In8bio’s mission and how gamma-delta T cells are one of the most exciting frontiers in immunotherapy. We’re building smarter, and potentially safer and more effective therapies for cancer & autoimmune disease.   Full interview here: empoweredpatientradio.com/ga…

A big thank you to #IO360, Kate Woodard, @AxelHoos and Valerie Bowling for giving me the opportunity to share why I think @In8bio is taking a fundamentally different approach in the race to bring a new therapy to autoimmune diseases. By my last count, over 45 programs are chasing CD19 CAR-T for autoimmunity. But few are asking tough questions about safety, scalability, or patient access. At IN8bio, we chose not to follow the herd. Instead, we’ve built something new: a gamma-delta T cell engager designed to deeply deplete B cells potentially without the toxicity seen with CAR-T or traditional CD3-based engagers. We think this is important for a number of reasons: • Many CAR-T trials quietly avoid enrolling women due to lymphodepletion risks—especially permanent ovarian damage. • There are a huge number of commercial and operational challenges around delivering complex CAR-T therapies in autoimmune settings, especially across multiple siloed departments in hospitals (hematology, rheumatology, etc.). • T cell engagers offer a simpler, potentially safer, and more scalable path—but most γδ approaches to date haven’t worked due to poor expansion. We may have cracked the code. Our INB-619 candidate has been shown to deliver significant expansion of γδ T cells, with robust B cell killing and no IL-6 spike—which could mean no CRS or ICANS. This is a major moment of opportunity, and risk for companies entering autoimmunity. Thoughtful design, commercially attractive profiles and a path to patients will separate the real contenders. #CancerZero

Yesterday we presented at TD Cowen—excited to unveil INB-600, our next-gen γδ T cell engager! • TCEs are a billion-dollar success in immunotherapy (J&J, Roche) • INB-619 not only engages γδ T cells but expands them for a stronger, longer-lasting immune response • Designed for blood cancers & autoimmune diseases with a potentially safer, more effective approach than CD3-based TCEs A game-changer for γδ T cell therapies. More to come! $INAB

So proud of the @In8bio team and truly honored to partner with Dr. McGuirk and the whole @KUCancerCenter team. Together we are working towards our mission of achieving Cancer Zero and making a difference for leukemia patients!
"These results are truly exciting. We are seeing something we rarely encounter in high-risk leukemia patients: sustained, durable remissions with minimal side effects to date. These continued results of INB-100, with the manageable toxicity profile, suggest it could become an attractive cellular therapy with the potential to extend survival in this difficult-to-treat patient population.” - @KUCancerCenter's Dr. Joseph McGuirk

Wrapping up #JPM2025, the mood seemed quite dour, especially on the buy side. However, starting the week on the oncology panel for #BiotechShowcase, I'm optimistic! Many are advancing innovative science to make a difference for cancer patients. Thanks to the great panel members including @pmunstermd, Mo Trikha, @histosonics, Joel Sandler, and @MyOncology. Good luck to all in 2025!

Yesterday, we proudly announced long-term PFS data in our Ph 1 trial of INB-100 allogeneic #gdTcells for #Leukemia at #ASH24. Read more: bit.ly/4iveWCU. Our entire team in collaboration with @KUcancercenter have worked hard to continue to advance this trial, bringing a potential new therapy to older adults with high-risk AML. #CancerZero is more than our Mission; it is our continued effort to bring impactful therapies to patients with severe diseases and significant unmet needs. We look forward to continued data from these patients and our expansion cohort in 2025! $INAB #CellTherapy #Oncology #ASH2024 #CellTherapy #Leukemia #AML @IN8bio

TV and the media often portray #CEOs as symbols of #success and glamour. Yet seldom showcased are the relentless challenges - the constant travel, lack of sleep, jet lag, stress and endless meetings in dreary conference rooms. But what makes it all truly worthwhile? It's the team we've assembled and our mission of achieving #CancerZero that fuel us. As the leader of this remarkable group at IN8bio, I take pride in educating investors, analysts, clinicians and others about the groundbreaking technology we are developing and the progress we are making. Here's to a fantastic 2024, filled with #innovation, advancement and shared #victories! Together, let's continue our journey towards conquering cancer. $INAB, #Biotech, #GDTcells; #Leadership, #CancerResearch, #CEOinsights, #MissionDriven, #2024Goals
