Femtech company raises €4.22m to improve gynaecological diagnostics
Endometrial cancer begins as a growth of cells in the uterus and is traditionally diagnosed with the help of an endometrial biopsy
A Spanish femtech company has raised €4.22m in funding to advance gynaecological diagnostics.
Barcelona-based start-up Mimark Diagnostics, a spin-off from the Vall d’Hebron Research Institute (VHIR), aims to speed up the discovery, verification and validation of biomarkers to develop new solutions for gynaecological patients.
Its in vitro diagnostic test for endometrial cancer is now in the last stage of prototyping and is hoped to move to the verification and validation stages.
Endometrial cancer, also known as uterine cancer, is a type of cancer that begins as a growth of cells in the uterus. It is traditionally diagnosed with the help of an endometrial biopsy, a procedure in which a tissue sample is obtained from the endometrium.
However, this could leave up to 30 per cent of patients undiagnosed due to technical failure or an inadequate amount of tissue.
Mimark’s innovation, which looks at five protein biomarkers in uterine fluid samples, aims to provide patients with a better diagnosis method and offer them more information on the histological subtype of the tumour to guide surgical treatment.
“This seed funding represents a significant milestone for Mimark and validates our commitment to improve gynecological diagnostics,” said Marina Rigau, co-founder and CEO of Mimark.
“Thanks to this funding we will advance on bringing our first product to the market; an in vitro diagnostic for endometrial cancer. We are excited about the journey ahead and the positive impact our innovations will have on women’s health.”
The investment is hoped to drive the development of the company’s solutions, with EU participation from the EIC Accelerator (European Innovation Council) and private investors, including Clave Capital, Nara Capital, Namarel Ventures, WA4STEAM, CDTI Innvierte, Inveready and Canterbury Scientific.
The funds, Rigau added, will be “instrumental” in advancing Mimark’s mission.
According to the co-founder, the start-up will be starting to accelerate the verification and clinical validation of WomEC, expand research and development efforts and strengthen collaborations with healthcare institutions in the field of gynaecology.

Small bowel microbiome differences between women and men may help explain why some conditions are more common in women, a study suggests.
The small bowel microbiome is the community of microorganisms living in this part of the digestive tract, where they play vital roles in immune function, metabolism and hormonal regulation.
Researchers found differences between women and men in the composition and organisation of these microbial communities. One bacterial community containing Granulicatella was found only in women.
The study was conducted by investigators at Cedars-Sinai Health Sciences University.
Ruchi Mathur, director of clinical research and clinical operations for the Medically Associated Science and Technology (MAST) Program at Cedars-Sinai and corresponding author of the study, said: “One intriguing finding was a bacterial community containing Granulicatella, which we found only in women.
“Bacteria in this community appear at increased levels in women with polyendocrine metabolic ovarian syndrome, formerly known as polycystic ovary syndrome.”
The researchers also identified differences between women and men in how microbes in the small bowel produce fructans, complex carbohydrates known to trigger digestive symptoms in irritable bowel syndrome (IBS).
IBS is far more common in women than men.
Mathur, who is also a professor of medicine, said: “Our findings show that biological sex is a critical variable in the small bowel microbiome.
“We must consider it as we move toward more personalised approaches to understanding and treating disease.”
An experimental cancer drug reduced bone loss and body fat in mice modelling post-menopausal changes, early research suggests.
The compound, CADD522, appeared to strengthen bones and help the animals stay leaner after surgery designed to mimic hormonal changes seen after menopause.
The treatment remains at an early experimental stage and has so far only been tested in animals.
The study, led by the University of East Anglia, investigated CADD522, which was originally developed to block a protein involved in the growth and spread of several cancers.
Mice treated with the compound for eight weeks showed significant improvements in bone health. Scans found increased bone volume and better preservation of the honeycomb-like structures inside bones that are crucial for strength and resilience.
Blood tests suggested the treatment stimulated new bone growth without interfering with the body’s normal process of breaking down and rebuilding bone.
Dr Darrell Green, lead researcher from UEA’s Norwich Medical School, said: “Osteoporosis affects around one in three women over the age of 50, leaving sufferers vulnerable to painful fractures that can seriously impact quality of life.
“Current treatments exist, but many are plagued by side effects, safety concerns or inconvenient dosing schedules that make long-term use difficult.”
The researchers also found that mice receiving CADD522 weighed less than untreated mice despite eating the same amount of food.
They had less body fat and fewer fat deposits in their bone marrow, a process commonly seen after menopause and linked to declining bone health.
The team also examined brain tissue and found that the drug appeared to reverse several menopause-related changes in fatty acids.
Levels of omega-3 fats including DHA remained largely intact, while several other lipid abnormalities shifted back towards healthier patterns.
Green said: “We didn’t directly test for memory or thinking ability, but our work raises questions about whether this drug could one day help address wider menopause-related health problems.”
Safety experiments in mice, rats and dogs found that CADD522 could be taken orally and was well tolerated.
The compound also appeared to be metabolised more slowly in human tissue than in rodents, potentially improving its performance in people.
“This is still in the early stages and has so far only been tested in animals but we hope that the benefits will translate to humans to ultimately reduce fracture rates,” added Green.
The research was led by UEA in collaboration with the University of Maryland, the Scintillon Research Institute in San Diego and the University of Stirling.
Safety testing was funded by The Sir William Coxen Trust as part of the development of CADD522 as a childhood cancer treatment.
Weight loss surgery was linked to more regular periods and fewer polyendocrine metabolic ovarian syndrome (PMOS) symptoms in women aged 18 to 45 living with obesity in a recent study.
The researchers recommend that women undergoing the procedure have access to preconception care and reproductive counselling to support their reproductive health.
Researchers at the University of Surrey analysed data over 24 months from 84 women who underwent bariatric surgery and 18 women living with obesity who did not have surgery.
Of those who underwent surgery, 49 had gastric bypass procedures and 35 had gastric sleeve surgery.
Women who underwent metabolic bariatric surgery lost more than 30kg on average at 12 and 24 months after the procedure.
Among women with polycystic ovaries, the condition persisted in only 10 per cent after 24 months.
Women also reported a resolution of clinical hirsutism, or excess body hair, by 12 months.
Women who had previously experienced irregular periods reported more regular menstrual cycles after surgery.
Professor Martin Whyte, co-author of the study and professor of metabolic medicine at the University of Surrey, said: “A large proportion of those undergoing bariatric surgery are women of reproductive age, who may be planning a pregnancy in the coming years.
“So much remains unknown about the impact of this type of surgery on women who are planning to have children.
“This raises the question of when the ideal time after surgery is to conceive.”
Women have a higher prevalence of obesity than men, with 57 per cent of women in the UK classified as overweight and 27 per cent living with obesity, which can affect fertility and the health of an unborn baby.
The researchers said 17 women had healthy pregnancies following surgery.
Although this was not specifically examined in the study, no difference in birth weight was observed between babies conceived within or after the first year.
Dr Kathryn Hart, co-author of the study and associate professor in nutrition and dietetics at the University of Surrey, said: “What we have found is that bariatric surgery positively affects the reproductive health of women living with obesity and can improve the likelihood of them having a healthy pregnancy after surgery.
“Dysregulated hormone levels, irregular periods and conditions such as polycystic ovaries are affected by obesity.
“By reducing this, what we have seen is that it can lead to improvements without the need for medication.
“We would suggest that clinicians consider medical intervention for obesity to treat irregularities in the menstrual cycle and issues with fertility.”
