Innovative Startups Challenging Established Pharmaceutical Companies

Atom Bioworks is demonstrating a remarkably swift development trajectory and possesses substantial potential for impact. As previously highlighted in our selection of promising demo day companies, this firm appears to be nearing a significant breakthrough in biochemistry: the creation of a programmable DNA machine.

These innovative tools enable the precise “coding” of molecules, ensuring they consistently bind to specific substances or cell types, thereby facilitating a range of subsequent actions.

For example, a DNA machine could identify and attach to COVID-19 viruses, subsequently releasing a signal to indicate infection before neutralizing the viral threat. This same principle is applicable to cancerous cells or bacterial organisms.

The foundational techniques developed by Atom’s researchers have been detailed in the journal Nature Chemistry, and the company is currently focused on developing a COVID-19 diagnostic test, alongside therapies targeting the virus and other medical conditions. Projected revenues are anticipated to reach the nine-figure range.

LiliumX represents another company pursuing a similar avenue of research, concentrating on “biospecific antibodies.” These can be considered pre-fabricated DNA machines. Naturally occurring antibodies within our bodies learn to target pathogens and unwanted substances, and engineered, administered antibodies can perform analogous functions against cancer cells.

LiliumX employs an algorithmic methodology to generate potential antibody structures with high efficacy, mirroring the approach adopted by numerous AI-driven biotechnology firms. However, the company also utilizes a robotic testing platform to refine its candidates and obtain in vitro validation for the most promising options. Advancing beyond initial lead identification is a challenging step, but significantly enhances the company’s overall value.

Entelexo is further along in the development process, dedicating its resources to a promising therapeutic class known as exosomes, which hold potential for treating autoimmune diseases. These minuscule vesicles – functioning as delivery systems for intercellular communication – can transport diverse materials, including customized mRNA capable of altering cellular behavior.

Systematically modulating cell behavior could offer relief from conditions such as multiple sclerosis, although the company has not yet disclosed the precise mechanisms involved – a complex explanation requiring more than a brief overview. They have already initiated animal trials, an unusual step for a company at this stage.

Nuntius Therapeutics is taking a further step, concentrating on methods for delivering cell-specific (targeting skeletal muscle, kidney cells, and others) DNA, RNA, and CRISPR-based therapies. A key challenge with these advanced treatments is ensuring delivery: while the therapeutic action is certain upon contact with the target cell, ensuring the agent reaches those cells remains problematic. Like emergency responders lacking an address, effectiveness is compromised without accurate delivery.

Nuntius asserts that it has developed a dependable method for delivering genetic therapy payloads to a variety of target cells, exceeding the capabilities of established pharmaceutical companies like Moderna. The company also independently develops and licenses its own therapies, positioning it as a comprehensive resource for genetic medicine should its techniques prove successful in human applications.

Beyond therapeutic interventions, the field of artificial organs is rapidly evolving. These remain largely experimental, due to the persistent risk of rejection, even when utilizing biocompatible materials. Trestle Biotherapeutics is addressing a specific need – kidney failure – with implantable, lab-grown kidney tissue designed to reduce reliance on dialysis for patients.

While the ultimate goal is to create complete kidney replacements, the immediate benefit for individuals with kidney failure is significant. Reducing the need for dialysis not only improves their prospects for receiving a donor organ or advancing on the transplant list, but also alleviates the burdens associated with this often-difficult procedure.

This collaborative venture between Yale and Harvard is led by a team with extensive experience in stem cell science and tissue engineering, including the 3D printing of human tissues – a technique undoubtedly integral to their approach.

Expanding Research Capabilities

Beyond therapeutic interventions, the recent YC cohort featured several ventures focused on enhancing the processes of research and comprehension regarding various conditions and their corresponding treatments.

While numerous sectors utilize cloud-based document platforms, such as Google Docs, for collaborative work and information sharing, the standard office suite may not always meet the specialized needs of scientists. Their disciplines often require unique documentation and formatting standards.

Curvenote is a document platform specifically designed for researchers; it offers integration with Jupyter, SaturnCloud, and Sagemaker. It supports a wide range of import and export functionalities, incorporates visualization plugins like Plotly, and utilizes Git for version control. Securing departmental approval for its cost may be the next challenge.

Pipe | bio presents a more focused cloud-based solution, providing hosted bioinformatics services for the development of antibody drugs, including LiliumX. The complex computational and database requirements within the biotechnology industry often necessitate specialized expertise.

Employing a readily available, paid tool is generally more efficient than relying on data science graduate students for supplementary work. (Furthermore, avoiding special characters in company names is advisable, as it may present challenges.)

Innovative tools extend beyond laptops to encompass benchtop equipment, as demonstrated by the remaining companies operating in the physical realm.

Forcyte, previously featured in our demo day company highlights, concentrates on the physical phenomena experienced by cells, rather than solely on chemistry or molecular biology. Systematic observation of these phenomena is challenging, yet crucial for numerous reasons.

The company employs a micropatterned surface to observe individual cells, specifically monitoring contraction and other morphological alterations. Cellular constriction and relaxation are fundamental to several significant diseases and their treatments, making their observation and tracking invaluable for researchers.

Forcyte aims to provide a scalable drug testing platform targeting these properties and reports identifying promising compounds for lung fibrosis. The team’s publications in Nature and a $2.5 million SBIR award from the NIH represent substantial validation.

Kilobaser is addressing the expanding DNA synthesis market. Companies frequently outsource custom DNA molecule creation to specialized synthesis laboratories. However, smaller-scale needs may be more efficiently addressed in-house.

Kilobaser’s benchtop device simplifies the process, making it accessible even to individuals without extensive technical expertise. With a supply of argon, reagents, and microfluidic chips (available from the company), it can replicate digitally submitted DNA in under two hours. This advancement could accelerate testing in numerous small laboratories currently constrained by external facility dependencies. The company has already sold 15 machines at €15,000 each, with ongoing revenue anticipated from consumable refills.

Reshape Biotech offers a direct approach to automating routine laboratory tasks: the creation of customized robots for each specific function. While conceptually simple, its execution is complex. However, given the commonality of lab layouts and equipment, a bespoke robotic sampler or autoclave could find widespread adoption as an alternative to employing additional part-time graduate students.

Several other noteworthy companies within the biotechnology and medical sectors were present in the cohort, but a comprehensive review of each is beyond the scope of this article. It is evident, however, that this space is becoming increasingly receptive to startups as technological and software advancements overcome previously insurmountable barriers to entry.
