IN8bio's INB-200 Shows Promise with Extended Survival in GBM
Positive Results for INB-200 in Glioblastoma Treatment
IN8bio, Inc. (NASDAQ: INAB), a pioneering biopharmaceutical firm, recently unveiled encouraging findings from its Phase 1 clinical trial of INB-200 for patients newly diagnosed with glioblastoma multiforme (GBM). This innovative treatment approach highlighted remarkable outcomes, showing that repeated doses of INB-200 lead to a median progression-free survival (mPFS) of 16.1 months, which is notably over double the 6.9 months commonly associated with the standard-of-care (SOC) Stupp protocol.
Clinical Data Highlights
The Phase 1 trial outcomes demonstrated compelling results. Not only did repeated doses of INB-200 showcase impressive mPFS rates, but the treatment also remained well tolerated among patients. Reports indicated that there were no serious toxicities beyond those typically observed with chemotherapy, and critical side effects such as cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) were absent.
Of particular note, four patients who received multiple doses of INB-200 remained alive and progression-free for longer than two years. This outcome underscores the therapy's potential to significantly benefit patient survival rates and improve quality of life.
Expert Insights on the Study
Dr. Burt Nabors, Division Director of Neuro-Oncology at the Heersink School of Medicine and Principal Investigator for the study, expressed optimism regarding the findings: “The data illustrates the robust potential of INB-200 in extending mPFS in GBM patients, including those with tumors resistant to conventional chemotherapy.” He further noted the promising trend of patients experiencing functional recovery and the ability to return to work, highlighting a meaningful shift in patient outcomes.
Repeated Dosing Benefits
The therapeutic strategy involves utilizing genetically modified gamma-delta T cells administered directly into the brain, combined with SOC chemotherapy. This innovative methodology not only sought to improve mPFS but also aimed to surpass historical survival benchmarks associated with standard treatments, establishing INB-200 as a novel approach for patients battling GBM.
No Increased Safety Risks Observed
Among the 13 patients involved in the trial, there were no dose-limiting toxicities reported. Adverse events were mostly mild, corresponding with those typical of radiation and temozolomide treatments. The absence of treatment-related fatalities reinforces the safety profile of INB-200.
Further Developments and Future Outlook
Looking ahead, IN8bio is committed to advancing its research in the field of cancer therapy. The company aims to develop deeper responses in patients to improve overall survival rates. The encouraging clinical data shared at the recent ASCO Annual Meeting illustrates the significance of their gamma-delta T cell therapies in providing potentially life-changing treatment alternatives for patients with aggressive cancers like GBM.
In addition to INB-200, the ongoing research into INB-400 also shows promise. Preliminary results from a separate Phase 2 trial have indicated an mPFS of 10.8 months in newly diagnosed GBM patients, with updates expected to emerge in the future.
How INB-200 Works
IN8bio's approach harnesses the natural capabilities of gamma-delta T cells to target tumors effectively. By delivering these cells directly to the tumor site following surgery, the therapy applies sustained immune pressure, aiming to eradicate remaining cancer cells and minimize the chances of relapse.
Upcoming Conference Call
In light of these encouraging results, IN8bio will host a conference call featuring Dr. Burt Nabors to discuss the updated clinical data. Interested participants can access the webcast on the company’s website. It’s advisable for attendees to register ahead of time to ensure smooth participation.
