As 3D printing technology gains acceptance with pharmaceutical companies, clinical laboratories could see increased demand for pharmacogenomic testing
Will physicians someday “print” prescription drugs for patients in-office? It sounds like science fiction, but research being conducted at the University College London (UCL) indicates the capability may be closer than we think, and it could bring about a new type of collaboration between clinical laboratories, ordering physicians, and pharmacies.
UCL’s new 3D technique, which it calls “volumetric 3D printing,” is intended to enable the pharmaceutical industry to tailor drug dosage, shape/size, and release to an individual patient’s needs and preference. A key element of precision medicine.
According to GlobalData Healthcare, 3D printing also can “significantly reduce cost, wastes, and economic burden as printers only deposit the exact amount of raw materials required.”
3D printing may enable pharmaceutical companies to address gender and racial disparities in prescription drug manufacturing through a developing technology that could have implications for clinical laboratory testing. Fred Parietti, PhD (above), co-founder and CEO of Multiply Labs, a technology company that develops robotics for precision medicine pharmaceuticals, told 3D Natives, “Currently, medications are developed especially for white adult men, which means that all women and children have an excessive prescription for their bodies. This fact underlines the importance of the advent of personalized medicines, as well as highlighting the individuality of each patient, since the error in the dosage of certain active ingredients can even lead to the malfunctioning of some treatments.” (Photo copyright: Multiply Labs.)

Increased Demand for Pharmacogenomic Testing
Though 3D printing of prescription drugs is not directly in the clinical laboratory/pathology space, it is noteworthy because it shows how technological advancements are progressing that actualize the ability to deliver precision medicine care to individual patients.
In turn, this could increase physician/patient demand for pharmacogenomic tests performed by clinical laboratories. The test results would be used by treating physicians to determine proper dosages for their individual patients prior to ordering 3D-printed drugs.
Being able to provide medication tailored to patients’ specific needs could bring about a revolution in pharmaceutical manufacturing. If 3D printed prescription drugs become mainstream, the demands could affect the clinical laboratory and pathology industries as well.
How Far Are We from Mass Production of 3D Printed Drugs?
The first and only 3D printed pharmaceutical drug on the American market is Spritam (levetiracetam) an anti-epileptic drug developed by Aprecia Pharmaceuticals, according to Medical Device Network. It received FDA clearance under the name Keppra in 1999.
Headquartered in Blue Ash, Ohio, Aprecia’s patented ZipDose manufacturing process allows 3D-printed pills to hold a larger dosage and dissolve rapidly. They currently have the only FDA process-validated 3D printing platform for commercial-scale drug production. They are leading the way on this new 3D technology and others are following suit.
FabRx, a start-up 3D printing company developed by academic researchers in 2014 at the University College London, released its first pharmaceutical 3D printer for personalized medicine called M3DIMAKER according to LabioTech.eu. The system is “controlled by specialized software, allowing the selection of the required dose by the pharmacist according to the prescription given by the clinician,” the company’s website notes.
The technology also allows for additional customization of pills, including the application of Braille for visually impaired patients, and printing of Polypills, which combine more than one drug into a single pill.
Other company’s developing 3D printing of pharmaceuticals, according to LabioTech.eu, include:
Germany’s Merck: currently in clinical trials of 3D printing medication with the goal of reaching large scale production.
China’s Triastek: which holds “41 patents that account for more than 20% of global 3D printing pharmaceuticals applications.”
We are still far away from large scale production of drugs using 3D printing, but that doesn’t mean it should not be on clinical laboratory leaders’ radar.
The rise of 3D printing technology for precision medicine could lead to big changes in the pharmaceutical world and alter how patients, providers, and clinical laboratories interact. It also could increase demand for pharmacogenomic testing to determine the best dosage for individual patients. This breakthrough shows how one line of technology research and development may, as it reaches clinical use, engage clinical laboratories.
The antibodies target portions of the SARS-CoV-2 spike protein that resist mutation, potentially leading to better treatments and vaccines
One challenge in the battle against COVID-19 is the emergence of SARS-CoV-2 variants, especially the Delta variant, which may be more resistant to neutralizing antibodies compared with the original coronavirus. But now, scientists led by researchers at the Fred Hutchinson Cancer Research Center (Fred Hutch) in Seattle say they have identified antibodies that could be broadly protective against multiple sarbecoviruses, the subgenus that contains SARS-CoV-2 as well as SARS-CoV-1, the virus responsible for the 2002-2004 severe acute respiratory syndrome (SARS) outbreak.
In “SARS-CoV-2 RBD Antibodies That Maximize Breadth and Resistance to Escape,” the researchers described how they compared 12 antibodies obtained from patients infected with either SARS-CoV-2 or SARS-CoV-1. They pointed to one antibody in particular—S2H97—that could lead to development of new vaccines and therapies against current and future variants. It might even protect against sarbecoviruses that have not yet been identified, they wrote.
Unsaid in the news release about these research findings is the fact that these particular antibodies could eventually become useful biomarkers for clinical laboratory tests designed to help physicians determine which patients have these antibodies—and the protection from infection they represent—and which do not.
So far, however, S2H97 has only been tested in hamsters. But results are promising.
“This antibody, which binds to a previously unknown site on the coronavirus spike protein, appears to neutralize all known sarbecoviruses—the genus of coronaviruses that cause respiratory infections in mammals,” said Jay Nix, PhD, an affiliate in Berkeley Lab’s Biosciences Area and Beamline Director of the Molecular Biology Consortium at Berkeley Lab’s Advanced Light Source (ALS), in a Berkeley Lab news release. “And, due to the unique binding site on mutation-resistant part of the virus, it may well be more difficult for a new strain to escape,” he added.
Scientists have long known that the SARS-CoV-2 virus uses the spike protein to attach to human cells. The federal Centers for Disease Control and Prevention (CDC) notes that the variants have mutations in their spike proteins that make some of them more transmissible.
The Delta variant, the CDC notes, was the predominant variant in the US as of August 28, 2021. It “has been shown to have increased transmissibility, potential reduction in neutralization by some monoclonal antibody treatments, and reduction in neutralization by post-vaccination sera,” the agency states.
The key to S2H97, the researchers wrote, is that it targets a portion of the spike protein that is common among sarbecoviruses, and that is likely to be resistant to mutations.
The researchers used a variety of techniques to analyze how the 12 antibodies bind to the virus. They “compiled a list of thousands of mutations in the binding domains of multiple SARS-CoV-2 variants,” Nature reported. “They also catalogued mutations in the binding domain on dozens of SARS-CoV-2-like coronaviruses that belong to a group called the sarbecoviruses. Finally, they assessed how all these mutations affect the 12 antibodies’ ability to stick to the binding domain.”
William Schaffner, MD (above), Professor of Preventive Medicine in the Department of Health Policy as well as Professor of Medicine in the Division of Infectious Diseases at the Vanderbilt University School of Medicine in Nashville, believes that “people who test positive for SARS-CoV-2 and who are at risk of progressing to severe disease—including those who are over the age of 65 years and those who have weakened immune systems—should talk with a doctor about receiving monoclonal antibody treatment,” Medical News Today reported. “[The monoclonal antibody treatment is] designed to prevent the evolution of the infection from a mild infection into a serious one,” he noted. “In other words, you’ve just [contracted the virus], but we can now give you a medication that will help prevent [you] being hospitalized and getting seriously ill.” (Photo copyright: Vanderbilt University.)
Earlier Antibody Treatment Receives an EUA from the FDA
In issuing the EUA for sotrovimab, the FDA cited “an interim analysis from a phase 1/2/3 randomized, double-blind, placebo-controlled clinical trial in 583 non-hospitalized adults with mild-to-moderate COVID-19 symptoms and a positive SARS-CoV-2 test result. Of these patients, 291 received sotrovimab and 292 received a placebo within five days of onset of COVID-19 symptoms.”
Among these patients, 21 in the placebo group were hospitalized or died compared with three who received the therapy, an 85% reduction.
“While preventive measures, including vaccines, can reduce the total number of cases, sotrovimab is an important treatment option for those who become ill with COVID-19 and are at high risk—allowing them to avoid hospitalization or worse,” stated Adrienne E. Shapiro, MD, PhD, of the Fred Hutchinson Cancer Research Center in a GSK news release. Shapiro was an investigator in the clinical trial.
The EUA allows use of sotrovimab in patients who have tested positive for SARS-CoV-2, have mild-to-moderate symptoms, and “who are at high risk for progression to severe COVID-19, including hospitalization or death. This includes, for example, individuals who are 65 years of age and older or individuals who have certain medical conditions.” It is not authorized for patients who are hospitalized or for those who require oxygen therapy.
The therapy was originally known as VIR-7831. The companies say they have developed a similar treatment, VIR-7832, with modifications designed to enhance T cell function against the disease.
The antibody, they wrote, targets a region of the SARS-CoV-1 spike protein that is “highly conserved” among sarbecoviruses. Clinical laboratory testing, they wrote, also indicated that the therapy was likely to be effective against known SARS-CoV-2 variants.
“Our distinctive scientific approach has led to a single monoclonal antibody that, based on an interim analysis, resulted in an 85% reduction in all-cause hospitalizations or death, and has demonstrated, in vitro, that it retains activity against all known variants of concern, including the emerging variant from India,” stated Vir Biotechnology CEO George Scangos, PhD, in the GSK news release. “I believe that sotrovimab is a critical new treatment option in the fight against the current pandemic and potentially for future coronavirus outbreaks, as well.”
Pathologists and clinical laboratory managers working with rapid molecular tests and antibody tests for COVID-19 will want to monitor the development of monoclonal antibody treatments, as well as further research studies that focus on these specific antibodies.
23andMe executives say they plan to leverage their database of millions of customer genotypes ‘tohelp accelerate personalized healthcare at scale,’ a key goal of precision medicine
In what some financial analysts believe may be an indication that popularity of direct-to-consumer (DTC) genetic testing among customers who seek info on their ethnic background and genetic predisposition to disease is waning, personal genomics/biotechnology company 23andMe announced it has completed its merger with Richard Branson’s VG Acquisition Corp. (NYSE:VGAC) and is now publicly traded on NASDAQ.
According to a 23andMe news release, “The combined company is called 23andMe Holding Co. and will be traded on The Nasdaq Global Select Market (“NASDAQ”) beginning on June 17, 2021, under the new ticker symbol ‘ME’ for its Class A Common shares and ‘MEUSW’ for its public warrants.”
Now that it will file quarterly earnings reports, pathologists and clinical laboratory managers will have the opportunity to learn more about how 23andMe serves the consumer market for genetic types and how it is generating revenue from its huge database containing the genetic sequences from millions of people.
After raising $600 million and being valued at $3.5 billion, CNBC reported that 23andMe’s shares rose by 21% during its first day of trading.
“23andMe is more than just a genetics company. We are an activist brand that is approaching healthcare and drug discovery with the individual at the center, as our partner,” said Anne Wojcicki (above), 23andMe’s co-founder and Chief Executive Officer, during remarks she gave after ringing the opening bell on the company’s first day of public trading, a 23andMe blog post noted. “We are going to continue pioneering a consumer-centered personalized healthcare world. We are going to show that drug discovery can be more efficient when you start with a human genetic insight,” she continued. (Photo copyright: TechCrunch.)
Might the quick rise in its stock price be a sign that 23andMe—with its database of millions of human genotypes—has found a lucrative path forward in drug discovery?
23andMe says that 80% of its 10.7 million genotyped customers have consented to sharing their data for research, MedCity News reported, adding that, “The long-term focus for 23andMe still remains using all of its accumulated DNA data to strike partnerships with pharmaceutical companies.”
Time for a New Direction at 23andMe
While 23andMe’s merger is a recent development, it is not a surprising direction for the Sunnyvale, Calif.-based company, which launched in 2006, to go.
Even prior to the COVID-19 pandemic, both 23andMe and its direct competitor Ancestry had experienced a decline in direct-to-consumer testing sales of at-home DNA and genealogy test kit orders. This decline only accelerated during the pandemic.
Meanwhile, 23andMe Therapeutics, a division focused on research and drug development, has been on the rise, Bloomberg News reported. On its website, 23andMe said it has ongoing studies in oncology, respiratory, and cardiovascular diseases.
“It’s kind of an ideal time for us,” Wojcicki told Bloomberg News.
“There are huge growth opportunities ahead,” said Richard Branson, founder of the Virgin Group, which sponsors the special-purpose acquisition company (SPAC) VG Acquisition Corp., in the 23andMe news release.
In a VG Acquisition Corp. news release, Branson said, “Of the hundreds of companies we reviewed for our SPAC, 23andMe stands head and shoulders above the rest.”
“As an early investor, I have seen 23andMe develop into a company with enormous growth potential. Driven by Anne’s vision to empower consumers, and with our support, I’m excited to see 23andMe make a positive difference to many more people’s lives,” he added.
Report Bullish on Consumer Genetic Testing
Despite the apparent saturation of the direct-to-consumer (DTC) genetic testing market, and consumers’ concerns about privacy, Infiniti Research reported that worldwide sales of DTC tests “are poised to grow by $1.39 bn during 2021-2025, progressing at a CAGR [compound annual growth rate] of over 16% during the forecast period.”
“This study identifies the advances in next-generation genetic sequencing as one of the prime reasons driving the direct-to-consumer genetic testing market growth during the next few years. Also, reduction in the cost of services and growing adoption of online service platforms will lead to sizable demand in the market,” the report states.
Clinical laboratory leaders will want to stay abreast of 23andMe rise as a publicly-traded company. It will be interesting to see if Wojcicki’s vision about moving therapies into clinics in five years comes to fruition.
The merger is expected to boost investment in 23andMe’s consumer health and therapeutics businesses
After years of spectacular growth, the popularity of direct-to-consumer (DTC) genetic testing is beginning to wane. Nevertheless, opportunities still exist in the DTC genetic testing market for visionaries with funds to invest.
One such visionary is billionaire Richard Branson, founder of the multinational venture capital conglomerate Virgin Group (VG). Branson’s VG Acquisition Corp. (NYSE:VGAC), a special purpose acquisition company (SPAC), announced it is merging with 23andMe of Sunnyvale, Calif., to create a publicly-traded company with the New York Stock Exchange ticker symbol ME.
In a VG press release, Branson states his reason for the merger. “Of the hundreds of companies we reviewed for our SPAC, 23andMe stands head and shoulders above the rest,” he said. “As an early investor, I have seen 23andMe develop into a company with enormous growth potential. Driven by [CEO Anne Wojcicki’s] vision to empower consumers, and with our support, I’m excited to see 23andMe make a positive difference to many more people’s lives.”
According to a 23andMe press release, the deal values the company at approximately $3.5 billion and will net the consumer genetics and research company as much as $759 million in additional cash. Wojcicki and Branson each invested $25 million themselves as part of the $250 million fund to take the company public.
“As a fellow industry disruptor as well as an early investor in 23andMe, we are thrilled to partner with Sir Richard Branson and VG Acquisition Corp. as we approach the next phase of our business, which will create new opportunities to revolutionize personalized healthcare and medicine,” 23andMe co-founder and CEO Anne Wojcicki (above) said in the press release. “We have always believed that healthcare needs to be driven by the consumer, and we have a huge opportunity to help personalize the entire experience at scale, allowing individuals to be more proactive about their health and wellness. Through a genetics-based approach, we fundamentally believe we can transform the continuum of healthcare.” (Photo copyright: Inc. magazine.)
Participation in Research Key to Future of DTC Genetics Testing
Though DTC genetic testing kit sales have slowed in recent years for both 23andMe and rival Ancestry, Wojcicki believes the company’s database of 10 million customers—with 80% of customers agreeing to participate in research—is the key to its future.
“We have always seen health as a much bigger opportunity” than genealogy, Wojcicki told The Wall Street Journal (WSJ).
According to the WSJ, 23andMe customers fill out more than 30,000 surveys each day on health and related issues. With that information, the company has determined its database includes 1.7 million people with high cholesterol, nearly 1.6 million with depression and 539,000 with Type 2 diabetes, information that is highly valued by medical researchers and those running clinical trials.
Personalizing Healthcare through DTC Genetic Testing
Wojcicki expects the merger will propel the consumer DNA-testing company into personalized medicine and therapeutics. “We have always believed that healthcare needs to be driven by the consumer, and we have a huge opportunity to help personalize the entire experience at scale, allowing individuals to be more proactive about their health and wellness,” Wojcicki said in a statement. “Through a genetics-based approach, we fundamentally believe we can transform the continuum of healthcare.”
In August 2020, the US Food and Drug Administration “granted 23andMe a 510(k) clearance for a pharmacogenetics report on two medications—Clopidogrel, prescribed for certain heart conditions, and Citalopram, which is prescribed for depression,” 23andMe announced in a blog post.
“This impactful pharmacogenetics information can now be delivered without the need for confirmatory testing, a testament to the clinical validity of 23andMe results,” said Kathy Hibbs, 23andMe Chief Legal and Regulatory Officer, in the blog post. “23andMe remains the only company with direct-to-consumer pharmacogenetic reports cleared by the FDA.”
23andMe’s trove of genetic data already has netted it a partnership with GlaxoSmithKline (GSK). According to a GSK press release, in 2018, the two companies signed a four-year research and development agreement. The collaboration targets novel medicines and potential cures using human genetics as the basis for discovery.
COVID-19 Boosts 23andMe’s Sales
During a joint interview with Branson in Bloomberg News about the merger, Wojcicki said, “COVID-19 has really opened up doors.” Now more than ever, she said, people are interested in preventative healthcare. “I’ve had this dream since 2003 that genetics would revolutionize healthcare and that’s really the era I see we can now usher in,” she added.
As 23andMe pushes further into personalized therapeutics, clinical laboratories and pathology groups would be wise to watch and see if this new entrant accelerates healthcare’s shift to the precision medicine model of personalized care.
Though gene sequencing is touted as a key component of precision medicine, the medical value of direct-to-consumer testing has yet to show up in improved health outcomes, nor have clinical laboratories benefitted
In a recent example that the market for genetic genealogy testing may have peaked and the days of spectacular growth in the number of direct-to-consumer (DTC) genetic test orders and revenue is over, private-equity firm Blackstone—in a $4.7 billion deal—announced it will acquire a majority stake in Ancestry, which also does some clinical laboratory genetic testing as well.
Blackstone (NYSE:BX) acquired Ancestry of Lehi, Utah, one of the two largest genealogy testing companies (the other being 23andMe of Sunnyvale, Calif.), from a group of equity holders led by investment firms Silver Lake, GIC, Spectrum Equity, and Permira, noted a press release. GIC will retain a “significant minority stake” in Ancestry.
“We are very excited to partner with Ancestry and its management team. We believe Ancestry has significant runway for further growth as people of all ages and backgrounds become increasingly interested in learning more about their family histories and themselves,” David Kestnbaum, a Senior Managing Director at Blackstone, said in the press release. “We look forward to investing behind further data, functionality, and product development across Ancestry’s market leading platform to continue to provide a differentiated service.”
Is Genetic Testing for Genealogy Still a Growth Industry?
Ancestry is the global leader in digital family history services, operating in more than 30 countries with more than three million paying subscribers across its Ancestry online properties and more than $1 billion in annual revenue.
However, some experts say the road ahead may not be smooth for Ancestry or its major competitor, 23andMe.
“The business landscape fell off a cliff last year,” Laura Hercher, Director of Human Genetics Research at Sarah Lawrence College in New York, told STAT. “Fads pass,” she added.
Hercher points out that Ancestry has “this enormous database, which inherently has a lot of value hidden in it—potential energy. But they have not figured out how to get that information out in the way 23andMe has.”
23andMe’s pivot into medical research gained steam in 2018 when pharmaceutical giant GlaxoSmithKline (NYSE:GSK) purchased a $300 million stake in the company with the aim of using 23andMe’s resources to develop new medicines. That collaboration began bearing fruit earlier this year when GlaxoSmithKline started human trials of the first medicine (a cancer drug) to emerge from the partnership, STAT reported.
The public’s declining interest in at-home genealogy, however, has caused both companies to reduce staffing. 23andMe began the year by laying off about 100 employees—an estimated 14% of its workers—and Ancestry followed suit in February, letting go a similar number of employees, representing roughly 6% of its workforce.
According to MIT Technology Review, direct-to-consumer genetic genealogy testing reached its zenith in 2018 when consumers purchased as many DNA tests in one year as they had in all previous years combined, propelling total sales from Ancestry, 21andMe, and other DTC gene testing companies to roughly $26 million.
In 2019, CNBC reported that, market-wide, roughly 30 million tests had been sold across the globe. However, in recent years, sales have fallen short of expectations as the number of people willing to pay $99 to learn about their ancestry has dwindled. “I suspect those that are curious about this information are thinning out and there’s less people to go around to grow,” Greg Yap (above), Partner at Menlo Ventures, told CNBC. “I think there’s a broader issue, which is that the ultimate medical value is still really unproven,” Yap added. “There’s lots of research being done, but value for mass market consumer isn’t there yet, so it keeps a ceiling on the size of that market.” (Photo copyright: VentureBeat.)
Privacy Still a Concern
Ancestry has begun to insert itself into the genetic testing healthcare arena. In a press release, the company announced the launch of AncestryHealth, a $179 DNA testing kit that uses next generation sequencing (aka, high-throughput or massive parallel sequencing), aimed at providing adult consumers information on their inherited health risks.
However, as MedCity News points out, the sale to Blackstone has increased privacy concerns around the direct-to-consumer DNA testing market. Ancestry’s consumer privacy and data protections remain unchanged under the new ownership, but Alan Butler, Interim Executive Director at Electronic Privacy Information Center (EPIC), told MedCity News, “This is one example of a very troubling trend. It’s something regulatory agencies are not up to date to deal with. It’s one of the reasons we need comprehensive privacy law in the US.”
As genealogy companies such as 23andMe and Ancestry shift their focus from providing genetic histories to improving consumers’ health through genetic testing, clinical laboratories should be mindful of the logical next step, which is predicted to be genetic tests where the consumer collects the sample at home and the test is used to aid in diagnosing and treating patients.
