A team of clinicians and scientists from the National University Cancer Institute, Singapore (NCIS) at the National University Hospital (NUH) and the N.1 Institute for Health at the National University of Singapore (NUS) has partnered Paxman Coolers (UK) to develop a device that may prevent or reduce numbness and pain caused by certain types of anti-cancer therapy.1
Chemotherapy-induced peripheral neuropathy (CIPN) is a severe side-effect of chemotherapy drugs called taxanes, which are used to treat common cancers such as breast, lung, ovarian and stomach cancer.
CIPN causes progressive and often irreversible pain or sensitivity in the hands and feet of patients undergoing chemotherapy leading to delays and discontinuation of treatment. It contributes to long-term poor patient well-being and significantly increases economic burden in terms of healthcare costs. The condition also leads to loss in work productivity, as affected patients are unable to return to work quickly.
Unmet clinical need
Few to no prevention and treatment strategies exist for CIPN. Recently, cryotherapy (or cooling) of the limbs during chemotherapy has demonstrated a protective effect by preventing/reducing CIPN severity. But, the currently used frozen gloves or ice packs are not user-friendly, deliver unstable cooling and can cause severe frostbite. There is a need for a medical device developed for patients’ use in a chemo suite and which can deliver stable cooling, tolerable over the entire duration of the chemotherapy.
A novel solution for CIPN
In collaboration with Paxman, the Singapore research team from NUHS comprising clinicians and researchers from the Department of Haematology-Oncology at NCIS and NUH, and the N.1 Institute for Health at NUS are developing a portable limb cryocompression device specifically targeting prevention of CIPN in cancer patients. The team has studied various proof of concept aspects of the cryocompression technology, over the past 8 years, previously supported by the National Health Innovation Centre Singapore (NHIC) through its Innovation to Develop grant. Working together as a team since 2019, Paxman, specialists in scalp cooling for prevention of chemo-induced hair loss, was identified as the ideal commercialisation partner for the project.
The research team has been awarded a translational grant from the National Research Foundation (NRF) Central Gap Fund in May 2021, which will be administered by NHIC. Pilot studies will commence in Q2 2022 to investigate the device in healthy volunteers, and cancer patients undergoing CIPN-causing chemotherapy. The efficacy of prevention will be monitored using various clinical and patient-reported outcomes.

“This funding is a testimony to the high impact the new product will have on the quality of life for cancer patients receiving taxane-based therapies, not only in Singapore, but throughout the world. It will allow our collaborative team, not only to crucially accelerate the R&D development process but will also significantly de-risk the project from a commercial perspective,” commented Mr Richard Paxman, CEO of Paxman.
“We bring to this collaboration extensive expertise in design, development, manufacture, regulatory approval, along with experience of commercialising medical cooling devices. The company is perfectly placed to roll out this technology to its existing and growing customer base throughout the world.”
