The recent findings from Biora Therapeutics regarding their BT-600 drug-device combination are a significant stride in the field of targeted drug delivery for ulcerative colitis treatment. The pharmacokinetic profile indicating successful delivery and absorption in the colon is a testament to the precision of the NaviCap™ device. The reduced systemic exposure of tofacitinib, a Janus kinase (JAK) inhibitor, could indeed minimize potential side effects commonly associated with JAK inhibitors, such as increased risk of infection and blood clots. The reduced maximum plasma concentration (Cmax) observed in the trial suggests a lower risk profile while potentially maintaining therapeutic efficacy at the site of inflammation.
From a pharmacological perspective, the implications of such targeted delivery systems are vast. They allow for the possibility of using higher doses locally without the corresponding increase in systemic side effects, which is a common limitation in the treatment of gastrointestinal diseases. Furthermore, the presence of the drug in fecal samples confirms the local delivery claim and suggests minimal systemic absorption, which is important for patients who are often on long-term treatments and are at risk of cumulative systemic toxicity.
The interim results of Biora Therapeutics' clinical trial are promising, especially considering the innovative approach of combining a drug-device for localized treatment. The pharmacokinetic endpoints met and the tolerability profile observed, provide a strong foundation for the continued development of BT-600. Notably, the 3-4 times lower systemic absorption when compared to conventional oral tofacitinib administration could suggest a favorable risk-benefit ratio for BT-600, which is a critical factor in drug development and regulatory approval.
It is also worth mentioning the potential economic impact of such a treatment. If BT-600 proves to be more effective or safer than existing therapies, it could lead to market share gains for Biora Therapeutics and possibly reduce overall healthcare costs by decreasing the need for more invasive treatments or the management of side effects. As the multiple-ascending dose (MAD) portion of the trial progresses, stakeholders should closely monitor patient outcomes and any signals of efficacy that could differentiate BT-600 from other treatments currently available for ulcerative colitis.
The advancement of Biora Therapeutics' BT-600 through phase 1 clinical trials is a noteworthy development in the biotech industry, particularly for companies focusing on gastrointestinal disorders. The successful interim results could have a favorable impact on the company's valuation and investor interest, as they suggest a potential breakthrough in the efficacy and safety of treatment for ulcerative colitis. The lower systemic drug levels achieved through the NaviCap™ device could position BT-600 as a leading candidate in the space of targeted therapy for inflammatory bowel diseases (IBD).
It is important to analyze the competitive landscape and the current standard of care for UC to fully understand the potential market impact of BT-600. The ability to deliver medication directly to the colon could give Biora Therapeutics a competitive edge over systemic treatments, which often come with a broader range of side effects. Moreover, the company's pipeline and technology platform could attract partnership opportunities, licensing deals, or even acquisition interest from larger pharmaceutical companies seeking to expand their IBD portfolio. The long-term implications for Biora Therapeutics will largely depend on the outcomes of the ongoing MAD trial and subsequent phase 2 and 3 trials, which will provide more comprehensive data on efficacy and safety.
All pharmacokinetic endpoints were achieved, with a PK profile consistent with drug delivery and absorption in the colon
All NaviCap™ devices performed as intended and were well tolerated, with no safety signals observed
Multiple-ascending dose (MAD) portion of the trial is underway and progressing well
SAN DIEGO, April 04, 2024 (GLOBE NEWSWIRE) -- Biora Therapeutics, Inc. (Nasdaq: BIOR), the biotech company that is reimagining therapeutic delivery, today shared additional positive interim results from the single-ascending dose (SAD) clinical trial of BT-600, which is a drug-device combination consisting of the orally administered NaviCap™ device that delivers a proprietary liquid formulation of tofacitinib to the colon. BT-600 is being developed for the potential treatment of patients with ulcerative colitis (UC). The SAD portion of the phase 1 randomized, double-blind, placebo-controlled clinical trial tested the tolerability and pharmacokinetics of BT-600 at 5 mg and 10 mg doses of tofacitinib, compared to placebo, in healthy adult participants.
“We are extremely pleased with the interim trial results, some of which we shared during our recent quarterly call, that demonstrate the NaviCap platform’s unique ability to achieve localized delivery to the colon, with a corresponding reduction in systemic drug exposure,” said Ariella Kelman, MD, Chief Medical Officer of Biora Therapeutics. “Direct delivery of JAK inhibitors to the colon has potential for improved efficacy driven by increased colonic tissue exposure, while reducing toxicity risks related to systemic exposure. We believe this could lead to better outcomes for patients suffering from UC.”
According to the interim clinical data, all pharmacokinetic endpoints were met in all study participants. BT-600 was well tolerated with no serious adverse events. All devices performed as intended, with all participants receiving BT-600 showing systemic drug absorption. Tofacitinib was first detected in plasma at approximately six hours following administration, which is consistent with colonic delivery as opposed to absorption in the upper GI tract. The mean time to reach maximum concentration (Tmax) was 8–10 hours following administration of BT-600, versus 0.5-1.0 hours for conventional oral tofacitinib. Tofacitinib was present in fecal samples of all subjects, further confirming delivery of the drug in the colon.
Colonic delivery of BT-600 was associated with 3–4x lower systemic absorption of tofacitinib, with a maximum plasma concentration (Cmax) of 26 ng/mL for BT-600 at the 10 mg dose of tofacitinib, versus 88 ng/mL for conventionally administered oral tofacitinib at a 10 mg dose.
“Many IBD drugs could benefit from localized delivery—research shows that for JAK inhibitors, integrin inhibitors and TNF inhibitors, higher colon tissue concentrations correlate with better outcomes,” said Adi Mohanty, Chief Executive Officer of Biora Therapeutics. “Our NaviCap platform represents a new therapeutic approach to UC and beyond. We continue to demonstrate that our localized delivery technology can enable higher colon tissue concentrations, without subjecting patients to high systemic drug levels, and results from the SAD portion of our clinical trial further confirm the platform’s capability.”
Highlights from the interim results can be found in the corporate presentation on Biora’s website.
The multiple-ascending dose (MAD) portion of the trial, currently underway, will evaluate daily doses of BT-600 for 7 days at 5 mg and 10 mg tofacitinib or placebo. Final results are expected to be available in late Q2 2024.
Phase 1 Clinical Trial Design
The objectives of this phase 1 randomized, double-blind, placebo-controlled, single and multiple ascending dose (SAD/MAD) clinical trial are to evaluate the safety, pharmacokinetics and pharmacodynamics, including effects on colon tissue, of BT-600 when administered orally in healthy adult participants. The study, which is being conducted in the United States, consists of two parts. The first part is comprised of 24 participants receiving a single ascending dose of BT-600 with tofacitinib at 5 mg or 10 mg doses or placebo. The second part is comprised of 24 participants receiving multiple ascending-doses of BT-600 with tofacitinib at 5 mg or 10 mg doses or placebo daily for 7 days. The trial is listed at clinicaltrials.gov (NCT06275464).
About the NaviCap™ Targeted Oral Delivery Platform
Biora's NaviCap targeted oral therapeutics platform utilizes a novel approach that could improve patient outcomes by enabling delivery of therapeutics directly to the site of disease, increasing therapeutic levels in tissue while reducing systemic uptake. For the 1.8 million patients in the United States who suffer from inflammatory bowel disease (IBD), existing therapeutics offer less than ideal efficacy, likely because of the challenges with safely achieving sufficient drug levels in the affected tissues. Research has shown that targeted delivery of therapeutics has the potential to improve patient outcomes in IBD.
The NaviCap platform uses an ingestible device designed for targeted delivery of therapeutics to improve treatment of IBD. Once swallowed, Biora’s GItrac™ autolocation technology enables the device to autonomously identify targeted locations in the GI tract and release a therapeutic dose of up to 500µl. Studies in healthy volunteers have demonstrated accurate localization and delivery in a fasted state and demonstrated the device’s ability to function in both fasted and fed states, making it potentially the first ingestible therapeutic delivery device that does not require fasting or other food restriction for use. A device function study in participants with active UC also demonstrated successful device performance in active UC patients.
