Problem

According to the WHO, in 2018, the global cancer burden increased to 18.1 million new cases, causing 9.6 million deaths. Despite the many advances in the matter of treatments, it is estimated that in 2040, cancer cases will increase to 29.5 million, and approximately 16.3 million will die because of it. One of the main reasons cancer has such a high mortality rate is due to the current lack of clinical tests with sufficient sensitivity and specificity to enable a timely diagnosis of this disease. In addition, the scarcity of technological resources to provide effective monitoring of the treatments applied, significantly reduces the patients’ chances of survival. The isolation of circulating tumor cells from the blood is a novel alternative to address these issues. 

Finding the needle in the hay stack

For most types of cancer, when a person develops a tumor, even if it hasn’t spread yet, it releases malignant cells into the bloodstream, known as circulating tumor cells or CTCs, which play a key role in establishing metastasis in other organs.

In the past few years, it has been demonstrated that CTCs can be isolated from blood, facilitating their enumeration and analysis. This could enable early cancer diagnosis and allow the proper monitoring of the therapies’ effectiveness when being administered to the patient. However, the isolation of these malignant cells from blood represents a major technological challenge due to their rareness. You can find ~37.5 billion cells in 7 ml of blood but, in a cancer patient, only 1 to 50 of those would be tumor cells; this is equivalent to identifying just a couple of people within the population of 5 Earths.

Even though there are cell sorting methods such as flow cytometry, density gradient centrifugation, among others, they do not have sufficient sensitivity and specificity to isolate CTCs. To be able to detect these rare cells, current methods would have to be ~100X more sensitive.

Cytocatch: detecting circulating tumor cells

Solution

At Delee we have created the CytoCatch™, a device that with a simple blood extraction starts a rapid process to successfully isolate circulating tumor cells.

Unlike other tests, CytoCatch™ possesses the required sensitivity and specificity to analyze the CTCs genetic features, as well as predictive and therapeutic markers expressed on them. Facilitating the early detection of cancer and enabling the personalization and optimization of each patient’s treatment. Because of this, patients and their families will be able to save time, reduce costs, prevent side effects of inefficient therapies, and more importantly, increasing their odds of defeating cancer.

Product

Able to diagnose and

monitor treatment

Once blood samples have been previously extracted by conventional methods, CytoCatch™ isolates the CTCs and automatically performs the necessary procedures to stain the captured cells with fluorescent antibodies, in order to discriminate the tumor ones from the other cellular components of the blood. Later, the integrated imaging system, which possesses artificial intelligence algorithms, analyzes the malignant cells, based on their morphology and the expression of specific antigens.

Our device is capable to individually collect tumor cells by implementing micromanipulation techniques, enabling to perform molecular analysis and assess the genetic characteristics of the CTCs. Finally, a report with the results will be given to the physician.

Clinical applications

The CytoCatch™ has the specificity and sensibility required to successfully isolate and analyze circulating tumor cells from blood, deriving on the following clinical applications:

Benefits

The early detection of cancer and the personalization of treatments for each patient can be translated into invaluable benefits for them and their families; the most important, and the main reason for our work is to increase their chances of defeating cancer and saving their lives. Monitoring the effectiveness of cancer therapies could also reduce the overall investment cost and the negative side effects caused by drugs that would not be effective.

For what types of cancer?

There is clinical evidence that supports CTCs as a powerful biomarker that can be used to early detect cancer and to monitor the effectiveness of the therapies that are being administered to patients with cancer, such as prostate, breast, colorectal, lung, cervical, melanoma, ovarian, among others. From the types mentioned above, the first four, alone, are responsible for more than a third of the defunctions occasioned by this disease.

Traction

We’ve gotten great traction since our pre-commercial launch of the CytoCatch™ device. To date, presales with a value of $1.4 million USD in potential revenue have been secured from research centers of various hospitals, to use our technology prior to FDA clearance. In addition, we’ve received attention from major research institutions and industry partners, including Harvard University, Stanford University, TEC de Monterrey, UANL, among others.

Delee has partnered with Sheppard Mullin, one of the top multinational intellectual property firms, to develop a strong IP strategy that strengthens our business globally. We’ve submitted both an international patent application PCT and provisional patent applications that encompasses hardware, software, biological protocols, applications, and data analysis methods.

Our work has been published in top peer-reviewed journals, and has been presented in various international conferences. Recently, our research was awarded by the Fundació Puigvert, a highly renowned international institution in the urology field, as the best clinical work presented at the congress of the American Confederation of Urology, this validates the interest of the medical community in our technology.

Customers

A tool for researchers and pharma

Prior to FDA clearance, Delee plans to commercialize the CytoCatch™ as a research tool; being pharmaceutical companies and research centers our main customers. Once the technology obtains the FDA approval, it can be commercialized, as an in vitro diagnostic medical device, to hospitals and laboratories. 

Business Model

Recurring revenue through consumable and reagent sales

Prior to FDA clearance, the razor and blades business model will be followed, obtaining recurrent revenue by selling the necessary reagents and consumables to perform each test. This model will be maintained after obtaining FDA approval for the commercialization of our technology.

Market

A $28.3B market by 2023

According to the report published by Market Research Future, in 2017, the global market for circulating tumor cells was valued at 9.39 billion USD, and it is estimated that by the end of 2023 it will reach a valuation of 28.3 billion USD. The increase in market valuation will be driven by the increment of the number of new cases and the expected mortality over time.

At Delee we are aiming to initially validate the CytoCatch™ in prostate and breast cancer and to further expand the validation to other types, such as lung and colorectal cancer. Because these four types of cancer are responsible for 40% of the new cases worldwide, triggering the deaths of 3.6 million people a year.

Competition

The more effective way

to capture CTCs

Most tests employed as auxiliaries for cancer diagnosis and therapies’ monitoring measure tumor marker levels in blood, typically proteins like PSA, CA 125 and AFP for prostate, ovarian and liver cancer, respectively. Nevertheless, those tests lack sufficient sensitivity and specificity, leading to an elevated number of false positive and negative results.

The isolation and analysis of CTCs is a relatively new practice, and physicians are starting to recognize all its potential benefits. Most CTCs technologies, including the CellSearch® System, which is considered the gold standard, rely on the existence of specific proteins on the cell membrane to capture CTCs. However, cancer cells are incredibly heterogeneous; when entering the bloodstream, they undergo a process in which the proteins used to capture CTCs are downregulated, limiting the capture of tumor cell subpopulations with diminished expression of there specific proteins, thereby losing valuable information. Our technology changes the norm by isolating CTCs irrespective of the lev of proteins expressed in their membranes, allowing us to capture cells that other technologies can’t.
