Cambridge startup launching clinical trial for bra tracking heart health

• Researchers say that's because women are underrepresented in clinical trials and because many mistakenly believe heart disease is limited to men.

State of play: Bloomer Tech received a $1.9 million grant from the National Institutes of Health last year to start a clinical trial on its medical device, a bra outfitted with flexible, washable sensors.

• The company is enlisting women undergoing cardiac rehab to join the trial, says founder Alicia Chong Rodriguez.

Zoom in: The bra, which the co-founders started developing nearly a decade ago at MIT, collects data about your cardiovascular system, hormones and metabolism, showing the results on an app.

• It comes in 12 sizes, ranging from 32B to 44C.
• The device underwent a feasibility study in 2018 and other tests with humans before Bloomer Tech prepared for the latest clinical trial.

The big picture: Bloomer Tech is one of several emerging women-led startups trying to address the gender gap in health care, which has led to less clinical trial representation and fewer resources to diagnose and treat women with various diseases.

• Chong Rodriguez attended the ARPA-H summit last month, where First Lady Jill Biden announced a $100 million investment in women's health research.
• President Biden yesterday signed an executive order to strengthen data collection and provide better funding opportunities for biomedical research in hopes of advancing women's health research.

• "It's unbelievable and unacceptable that it's still harder to recognize, diagnose and treat women with heart disease," says Chong Rodriguez, who was 13 when her grandmother, an obstetrician, died from the illness in Peru.

The intrigue: Bloomer Tech's product challenges what a conventional medical device looks like, just as activist Amelia Bloomer challenged women's fashion in the 19th century.

• Bloomer encouraged women to ditch corsets for the loose-fitting pantaloons that were eventually named after her.
• "Sometimes people look at our product and they think it's a consumer device," Chong says.
• "The fact that it still doesn't click that it's a medical device, it's interesting to me how we reinvented a medical device to look like something that goes in your closet."
