Innovative Cancer Treatment: The SHREAD Technology Revolution
Written on
Chapter 1: A New Dawn in Cancer Treatment
Recent advancements in cancer therapy have sparked optimism in the medical community. While the world collectively breathes easier with the rollout of effective COVID-19 vaccines, cancer remains a formidable adversary. This disease is one of the leading causes of mortality worldwide and has long eluded safe and effective treatments. Thankfully, signs of hope are emerging, with innovative therapies being developed and tested.
The advent of a new cancer vaccine has shown significant promise as it enters human trials. Just last month, I reported on a brain cancer vaccine that demonstrated both efficacy and safety during its Phase I trials. It’s encouraging to witness a shift in focus toward developing treatments for cancer, especially when we can create pandemic solutions in under a year.
Section 1.1: SHREAD Technology Explained
One remarkable advancement comes from researchers at the University of Zurich, who have created a novel technology that allows for the on-demand production of therapeutic agents precisely where they are needed in the body. This innovation aims to significantly reduce the adverse effects associated with traditional invasive treatments like chemotherapy and radiation. Additionally, it could enhance the delivery of COVID-19 therapies directly to the lungs.
“The therapeutic agents, such as therapeutic antibodies or signaling substances, mostly stay at the place in the body where they’re needed instead of spreading throughout the bloodstream where they can damage healthy organs and tissues.”
~ Andreas Plueckthun, Lead Researcher
Subsection 1.1.1: How It Works
Researchers began by modifying a common respiratory virus, adenovirus, to act as a Trojan horse, delivering genes for cancer therapeutics directly into tumor cells. This method is non-toxic to healthy cells but effectively instructs cancer cells to produce therapeutic antibodies and signaling substances that eliminate tumors from within.
Named ‘SHREAD’ (SHielded, REtargetted ADenovirus), this technology builds on previous advancements by the team, allowing for precise targeting of adenoviruses while evading the immune system. In animal studies, the SHREAD system demonstrated the ability to generate a clinically approved breast cancer antibody, trastuzumab, more effectively than direct injections.

Section 1.2: Promising Results
A few days later, researchers found that SHREAD produced a higher concentration of the antibody within the tumor compared to traditional methods. Moreover, it achieved lower levels in the bloodstream and surrounding tissues, thereby minimizing the risk of side effects. A sophisticated high-resolution 3D imaging technique was employed to visualize how the therapeutic antibody creates pores in the tumor's blood vessels, effectively destroying cancer cells from the inside.
While these trials focused on breast cancer, researchers are optimistic that SHREAD's lower side effect profile could make it suitable for a variety of potent biologics that are typically too toxic for standard treatments. Team members are now exploring its application for effective COVID-19 therapies. Notably, vaccines from companies like Johnson & Johnson and AstraZeneca utilize adenoviral vectors.
Chapter 2: Looking Ahead
As research continues, the potential for SHREAD technology to revolutionize cancer treatment is promising. This innovative approach may not only provide hope for cancer patients but could also pave the way for advancements in treating other diseases.
