Obsidian Therapeutics is leading the charge in developing cutting-edge treatments for stubborn illnesses. In a recent chat, CEO Paul Wotton shed light on how their cytoDRiVE® technology is revolutionizing the way we tackle diseases by controlling protein levels in cell and gene therapies, unlocking new possibilities for patient care.

Origins and Development of the Company

Based in the bustling hub of Cambridge, Massachusetts, Obsidian Therapeutics stands out as a beacon of innovation in the biopharmaceutical landscape. With its roots tracing back to groundbreaking research by Tom Wandless from Stanford University, this young company has quickly made a name for itself.

At its core, Obsidian’s pioneering technology hinges on an ingenious method to modulate protein and cell behaviors through medication. Imagine flipping a switch within our genes that responds to drugs, that’s exactly what they’ve achieved. By integrating a synthetic receptor into proteins, healthcare professionals can now tweak cellular activities with unprecedented precision by simply adjusting drug dosages. This technique not only marks a significant leap forward but also arms doctors with newfound capabilities to tailor treatments more closely to individual patient needs.

Their flagship innovation, dubbed cytoDRiVE®, is nothing short of revolutionary. For the first time ever, control over cell and gene therapies can be dialed up or down depending on the dose of medication administered. This advancement offers not just a new treatment modality but fundamentally changes how physicians approach care delivery.

Diving into their portfolio reveals their ambitious project: transforming tumor-infiltrating lymphocyte (TIL) therapy for cancer treatment. Traditional TIL therapy shows promise but comes saddled with drawbacks like high toxicity levels and cumbersome administration procedures due to IL-2 reliance. Obsidian’s solution? A novel program named cytoTIL15™. By substituting IL-2 with self-manufactured IL-15 within cells, they’re charting a course towards reducing side effects and costs while broadening accessibility for cancer patients worldwide.

Especially significant is the impact on melanoma treatment where approximately 20-30% of patients find themselves barred from TIL therapy options due to these very constraints. Through avoiding IL-2 altogether, Obsidian envisions a future where more patients have hope against relentless diseases.

Over merely five years since its inception in 2016, Obsidian has transcended its original research-focused identity to become a trailblazer in development amidst challenging times including the pandemic surge which didn’t slow them down but rather saw their team expand significantly.
As they edge closer to clinical trials less than twelve months away, buoyed by substantial funding secured through Series B financing totaling $115 million last fall; all signs point toward an imminent public offering on the horizon – further testament to their remarkable journey thus far and promising prospects ahead.

What are cell therapies, simplified for beginners?

In the realm of biotech innovation, cell therapies are leading the charge. This advanced approach enhances a cell’s ability to function by adding new genes that enable it to produce specific proteins. These proteins can be anything we choose, such as IL-2 or TNF-alpha, broadening the potential applications of this technology.

One practical application involves treating patients with melanoma, a prevalent form of skin cancer, by modifying their cells. By introducing an IL-15 gene into these cells, they become TIL cells which are significantly stronger and more effective in combating cancer.

Until recently, this cell modification process was performed outside the patient’s body. However, through a partnership with Vertex, strides are being made towards innovating a method that allows for direct gene editing within the patient’s body itself. This leap forward could revolutionize how we approach treatments for various conditions in the future.

Why Obsidian is a breakthrough for cancer patients

Embarking on a journey with Obsidian, I’ve set my sights on the pressing need for novel cancer treatments. The conventional methods—surgery, radiation, and chemotherapy—are relics of the past, attacking not just the cancer but the body as a whole without discrimination. Witnessing a loved one battle cancer highlighted this harsh reality to me firsthand.

The landscape of drug discovery is transforming, heralding an era where precision medicine tailors treatment to each patient’s unique condition. This shift promises to revolutionize how we combat cancer.

Central to this new frontier are immune therapies that empower patients’ own defenses to target tumors more effectively. Cancer overwhelms these natural defenses, but by bolstering them, we can fight off tumors more safely and efficiently.

I’m convinced that we’re on the cusp of a paradigm shift where cell therapies and immune technologies will become the go-to solutions, potentially rendering traditional chemotherapies obsolete in time. That day isn’t just a possibility; it’s within our grasp.

What do we know about your tech, cytoDRiVE?

Precision Oncology Treatments: Obsidian Therapeutics' Breakthrough in Enhancing TIL Therapy Safety and Efficacy

We have crafted a groundbreaking platform known as CytoDRiVE, revolutionizing the way proteins are managed within the human body through an FDA-approved molecule. This innovative approach allows for the modulation of protein levels by turning their expression on or off and adjusting their quantity with precision.

The magic behind this technology involves integrating a tiny DRD into cells, paving the way for the manipulation of protein expression via a small, safe molecule. Our flagship initiative, dubbed cytoTIL15, employs acetazolamide—a drug recognized for its safety by the FDA—as this crucial molecule. When acetazolamide interacts with the DRD, it effectively controls how much of certain proteins are produced.

Our application of CytoDRiVE technology has shown promising results in enhancing Tumor Infiltrating Lymphocytes (TILs). Here’s how it works: we extract tumor tissue from patients and isolate lymphocytes that have infiltrated the tumor. These cells are then modified to display IL-15 on their surface and reintroduced into patients’ bodies. The patient is directed to take a daily dose of acetazolamide to keep these enhanced cells active. Should there be a need to adjust the therapy’s intensity, doctors can simply modify the acetazolamide dosage accordingly, offering them precise control over treatment duration and potency.

With this pioneering method, we’re not just pushing boundaries; we’re redefining what’s possible in personalized medicine through controlled protein expression.

Have you faced any misunderstandings or moral challenges in your job?

In the realm of medical advancements, weighing the pros and cons of treatments is crucial. New therapies especially can spark a mix of hope and hesitation among people.
