New MedTech innovation allows tumors to eliminate themselves

MedTech innovation

MedTech seems to be reaching a new stride everyday as investments into the sector pour in at an accelerated rate, mainly due to the on-going global health crisis.

As such, a new technology has been developed by the University of Zurich (UZH), where researchers have successfully achieved innovation that allows the body to produce therapeutic agents on demand at the exact location where they are needed.

The innovation could reduce the side effects of cancer therapy and may hold the solution to better delivery of COVID-related therapies directly to the lungs.

According to a statement by UZH, scientists at the University have modified a common respiratory virus, called adenovirus, to act like a Trojan horse to deliver genes for cancer therapeutics directly into tumor cells.

“Unlike chemotherapy or radiotherapy, this approach does no harm normal healthy cells. Once inside tumor cells, the delivered genes serve as a blueprint for therapeutic antibodies, cytokines and other signaling substances, which are produced by the cancer cells themselves and act to eliminate tumors from the inside out,” the statement published by the university said.

Sneaky adenoviruses

“We trick the tumor into eliminating itself through the production of anti-cancer agents by its own cells,” says postdoctoral fellow Sheena Smith, who led the development of the delivery approach.

Research group leader Andreas Plueckthun explains that “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.”

The UZH researchers call their technology SHREAD: for SHielded, REtargetted ADenovirus.

It builds on key technologies previously engineered by the Plueckthun team, including to direct adenoviruses to specified parts of the body to hide them from the immune system.

Attacking the right target

According to UZH, with the SHREAD system, scientists made the tumor itself produce a clinically approved breast cancer antibody, called trastuzumab, in the mammary of a mouse.

They found that, after a few days, SHREAD produced more of the antibody in the tumor than when the drug was injected directly.

“The concentration in the bloodstream and in other tissues where side effects could occur were significantly lower with SHREAD. The scientists used a very sophisticated, high-resolution 3D imaging method and tissues rendered totally transparent to show how the therapeutic antibody, produced in the body, creates pores in blood vessels of the tumor and destroys tumor cells, and thus treats it from the inside,” the statement highlighted.

Uses against COVID-19

According to the main scientists spearheading this research, SHREAD is not only limited to the use of fighting breast cancer but can also be applicable for delivery in wide range of so-called biologics – powerful protein-based drugs that would otherwise be too toxic.

This is mainly due to healthy tissues no longer come into contact with significant levels of the therapeutic agent.

In fact, members of the Plueckthun group are currently applying their technology in a project aimed as a therapy for COVID-19. Adenoviral vectors are already being used in several of the COVID vaccines, including the Johnson & Johnson, AstraZeneca, China’s CanSino Biologics and Russia’s Sputnik V vaccines – but without the innovative SHREAD technology.

“By delivering the SHREAD treatment to patients via an inhaled aerosol, our approach could allow targeted production of Covid antibody therapies in lung cells, where they are needed most,” Smith explains. “This would reduce costs, increase accessibility of Covid therapies and also improve vaccine delivery with the inhalation approach.”

Vista Equity invests $300 million in telehealth software firm TigerConnect- sources

Published

Healthcare communications software provider TigerConnect has raised $300 million in growth investment from private equity firm Vista Equity Partners, sources familiar with the matter told Reuters on Monday.

The valuation of TigerConnect wasn’t known. It last raised $45 million at a valuation of $370 million in September 2020, according to PitchBook data, counting HealthQuest Capital and New Leaf Ventures as its backers. Some of the early investors have exited through Vista’s investment, one of the sources said.

Santa Monica, California-based TigerConnect delivers cloud-based clinical communication and collaboration solutions, including telehealth, to over 7,000 healthcare organizations and 700,000 caregivers.

In an interview, Brad Brooks, TigerConnect’s co-founder and chief executive confirmed the partnership with Vista, but declined to comment on the amount or valuation.

He said the company plans to use the proceeds to invest in its product to meet the growing need for clinical collaborations, as well as looking for acquisition opportunities.

The number of users on TigerConnect’s platform more than doubled during the past year as hospitals try to improve efficiency and the experience for patients during the pandemic, Brooks added.

“There had really been a dramatic lack of efforts around clinical workflow communication. We’re almost like a Slack for healthcare, putting in a common communication network so that everyone can reach everyone,” said Brooks.

The company, founded in 2010, sells subscription-based software solutions, including collaboration, communication, scheduling and patient engagement. It also plans to utilize AI and machine learning technology to provide smart solutions based on the platform data.

Vista has over $86 billion in assets under management and specializes in investing in enterprise software, data and technology companies. Last week, it invested an undisclosed amount in BlueConic, a Boston-based customer data platform.

AstraZeneca booster shot is effective against Omicron variant

Published

 on

A study from an Oxford University lab published on Thursday revealed that a three-dose course of AstraZeneca booster shot is efficient in controlling the fast spread of the Omicron variant.

The Pharmaceutical company said in its statement that the results – while they have yet to be released in a peer-reviewed medical journal – are relatively identical to those of its rivals, including Pfizer-BioNTech and Moderna. They also uncovered that their booster vaccines effectively fight the latest Coronavirus variant.

After receiving the third dose of AstraZeneca, the study highlighted that the shot had a neutralizing effect against the virus, which had an almost identical result to the two shots against its previous variant, Delta.

“As we better understand Omicron, we believe we will find T-cell response provides durable protection against severe disease and hospitalizations,” the head of AstraZeneca’s biopharmaceutical R&D, Mene Pangalos, said when referring to a significant element of the immune system that fights infection.

After taking the Vaxzervria – the third booster shot – antibody levels marked a much higher rate than antibodies in patients who had already caught the virus and naturally regained health, the Anglo-Swedish drugmaker said.

On Tuesday, the pharmaceutical firm announced that it is already working with its partner, Oxford University, to develop a vaccine exclusively directed towards fighting the Omicron variant, mirroring other MedTech companies’ attempts.

The university’s study incorporated 41 samples from individuals who had already taken the first two shots of AstraZeneca and others who took the booster one. The lab examined and analyzed blood samples from people infected with the virus and others vaccinated with the two dozes, the third booster shot, and finally, those who had already caught one of the coronavirus variants.

It is worth mentioning that AstraZeneca stated that while the Oxford University lab results support its booster shot, the study was completely independent of researchers who had previously joint efforts with the London-based firm on the vaccine.

The world is looking to halt back from the detrimental effect the pandemic is spreading, with governments and scientists seeking to heighten fortifications in their health sectors against the Omicron.

Even since its emergence on the scene, the latest COVID-19 variant proved to be one of the most dominant variants to date. Governments are worried it might become globally spread after the holidays if they fail to curb the infections rate.

Earlier this month, the UK endorsed third shots after discovering that boosters have a vital role in restoring protection against other diseases triggered by the Omicron.

Moderna, unfazed by Omicron, prepares for the 2022 vaccination campaign

Covid-19 vaccine-making veteran Moderna seems unfazed by the emergence of the Omicron variant, saying that they can begin work on developing a booster short within a couple of weeks, according to Chief Executive Stephane Bancel.

“It only needs minor adjustments for Omicron, I don’t expect any problems,” said Bancel in an interview with the Swiss newspaper TagesAnzeiger.

Though hoping to begin clinical trials in early 2022, for the time being, they will be relying on the booster dose of their mRNA-1273 vaccine to counter the fast-spreading coronavirus variant. 

The company is now awaiting vital information on the new variant to begin vaccine development, which could take up to one or two weeks.

Bancel says that it will take another few months to produce 500 million doses after all the regulatory requirements have been met, citing that their capabilities and experience as a company today have increased compared to one year ago.

In 2021, Moderna managed to create around 700 million to 800 million vaccine doses. In 2022, they expect to escalate production capacity from 100 million doses per month to 150 million per month. 

Deals were also made with Swiss-based drug manufacturer Lonza to boost production further and plan to fire up their factory lines in the first quarter of 2022.

The company is currently discussing a future ‘vaccine subscription’ service with Switzerland that works to ensure a steady supply. This move helps improve ties with the country, which Moderna is keen to proceed with after signing parliamentary agreements with Canada and Australia.

“We have a number of new vaccines in development, for example against influenza or against the RS virus, which causes a respiratory disease that is fatal in the elderly and young children,” Bancel added.

“We can combine these three mRNA vaccines into one dose and propose to governments to secure supplies for a certain amount for several years and then invest in a production facility in that country,” he added.

With this, the company can designate certain countries as having priority should another pandemic occur in the future.
