About Project

Problem: What problem is this project trying to address?

According to the WHO, Malaria affects half the world’s population, kills nearly a million annually, costs African economies $12B, and, in India alone, is responsible for 4.2 million disability­-adjusted life­ years. With only 1/8 infections properly diagnosed, there is a desperate need for simple and accurate diagnostics. Without such diagnostics, treatment cannot be administered for fear of resistance, costs, and potential side effects.

Solution: What is the proposed solution? Please be specific!

DDG's flagship product, the Rapid Assessment of Malaria (RAM), yields a quantitative diagnosis, in less than a minute, from a drop of blood, at 1/4th the cost and 100x the accuracy of current solutions by malaria's inherent magnetic biomarker. RAM is a purely mechanical, reusable device that takes and ultra low-cost plastic consumable cuvette which offers a simple intuitive diagnostic requiring minimal medical expertise. Critically, RAM will be the only point-of-care device sensitive enough to diagnose early-stage infections, filling the void in the elimination setting, and offer $1.2B in annual cost savings while helping stabilize developing economies by saving lives, limiting hospital stays, and conserving resources.

Impact: How does it Work

Example: Walk us through a specific example(s) of how this solution makes a difference; include its primary activities.

RAM's will fill the void in the elimination setting. RAM will be the only POC device capable of diagnosing the asymptomatic population. It can go to patients, as active screening tool, and, because of its speed and sensitivity, will allow NGOs and countries to screen and treat entire villages before the disease can spread and before the cost of treatment increases (treatment of symptomatic patients costs at least 6x more). Not only will this result in direct cost saving to these communities, but the saved lives and limited hospital stays will increase the productivity of the economy. In the future, our technology will be applied in a multiplex device capable of offering a diagnosis among a number of diseases, further increasing the value

Impact: What is the impact of the work to date? Also describe the projected future impact for the coming years.

RAM is not yet on the market, but once it achieves WHO approval following upcoming field trials, it is poised to make a huge impact because it merges the advantages and eliminates the disadvantages of current solutions. RAM matches the portability of an RDT while maintaining the accuracy, heat stability, and reusability of a microscope, without a need for expertise. And, while RAM is innovative and disruptive in nature, our business model and mechanical technology offer unprecedented partnership opportunities. In addition to saving organizations $100K over the lifetime of the device, lowering costs associated with treatment, and increasing economic productivity, the device is simple and label free, meaning that it can empower individuals in developing countries who don't have extensive training to use the device themselves and create a sustainable system for screening.

Spread Strategies: Moving forward, what are the main strategies for scaling impact?

Based on being best-in-class in all 6 WHO metrics, RAM will become the standard, and at 1/4th the cost, will increase the ratio of tests to treatment from under 1:1 to 4:1, meaning that every infection will be diagnosed. More critically, RAM will interrupt transmissions, allowing eradication, and because RAM provides a quantitative assessment of the infection, DDG can quantify how many more diagnoses were made, how much money was saved in treatment, how many lives are saved, and how much productivity was increased by limiting hospital visits. We anticipate impacting 1 million lives by 2018.

Financial Sustainability Plan: What is this solution’s plan to ensure financial sustainability?

We'll sell a reusable device that accepts a plastic consumable. The model balances profitability and social impact, and reduces lead-time and quality problems. Our $0.25 price point, equal to the COGS for RDT, is very favorable to NGOs and international institutions with whom we have spoken, saving them $100K over the lifetime of the device. Industry standard pays 30% upfront to sellers, making RAM, with COGS equal to 25%, immediately sustainable

Marketplace: Who else is addressing the problem outlined here? How does the proposed project differ from these approaches?

We have no real direct competitors, as our RAM device matches or surpasses current best in class standards and will provide the only quantitative diagnostic tool with a portable footprint. Through our customer interviews we understand the public market to be interested in scaling up RDTs, but this is not a long-term solution, as RDTs cannot distinguish low-level infections, have prices that scale significantly with sensitivity, and are limited due to their heat instability and short shelf life.

Founding Story

Diagnostics have been my passion since high school Science Olympiad and I got interested in malaria specifically after a childhood friend contracted the disease. As a Masters Student, I was working on a low­ cost ventilation system for malaria bed nets, when I became introduced me to the extent of the disease and began working with a team of physicists and biologists on the device, as I wanted to be a social entrepreneur to commercialize diagnostics for real impact. When I saw our first prototype, which we built with off-the-shelf components, work with for the first time with synthetic hemozoin, it was a very profound moment and I haven't looked back since.
