Singapore-UK Team To Develop a Novel Device to Reduce Chemotherapy Side-Effects

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 Ltd (UK) (Paxman) to develop a device that may prevent or reduce numbness and pain caused by certain types of anti-cancer therapy¹. 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 affects about 1.4 million cancer patients globally every year².

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. However, 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 eight years³, previously supported by the National Health Innovation Centre Singapore (NHIC) through its Innovation to Develop grant. Working together as a team since 2019, Paxman, global leaders 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.

Principal Investigator Assistant Professor Raghav Sundar, Consultant at the Department of Haematology-Oncology at the National University Cancer Institute, Singapore (NCIS) and Investigator at The N.1 Institute for Health at NUS, said, “This collaboration will have a significant and broad impact. By preventing or reducing CIPN, the overall health and quality of life of cancer patients will be significantly enhanced, during and after chemotherapy. The treatment of CIPN is an unmet and increasingly urgent clinical need, and a preventative solution will hopefully improve patient quality-of-life.”

Co-Principal Investigator Dr Aishwarya Bandla, Head of Translational Tx Core at The NUS N.1 Institute for Health, added, “This international multidisciplinary collaboration brings together complementary cross-sector expertise from the hospital, academia, and industry. The overall product-development process will utilise a patient-centered approach, placing the patients’ safety and efficacy at the heart of the design process.”

“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 research and development process but will also significantly de-risk the project from a commercial perspective,” commented Mr Richard Paxman, CEO of Paxman.

“Paxman is determined, not only to provide patient access to scalp cooling technology to prevent chemotherapy-induced hair loss globally, but now also to give patients the chance to reduce or prevent the debilitating side effect of peripheral neuropathy. 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.”

About the National University Health System (NUHS)
The National University Health System (NUHS) aims to transform how illness is prevented and managed by discovering causes of disease, development of more effective treatments through collaborative multidisciplinary research and clinical trials, and creation of better technologies and care delivery systems in partnership with others who share the same values and vision.

Institutions in the NUHS Group include the National University Hospital, Ng Teng Fong General Hospital, Jurong Community Hospital and Alexandra Hospital; three National Specialty Centres – National University Cancer Institute, Singapore (NCIS), National University Heart Centre, Singapore (NUHCS) and National University Centre for Oral Health, Singapore (NUCOHS); the National University Polyclinics (NUP); Jurong Medical Centre; and three NUS health sciences schools – NUS Yong Loo Lin School of Medicine (including the Alice Lee Centre for Nursing Studies), NUS Faculty of Dentistry and NUS Saw Swee Hock School of Public Health.

With member institutions under a common governance structure, NUHS creates synergies for the advancement of health by integrating patient care, health science education and biomedical research.

As a Regional Health System, NUHS works closely with health and social care partners across Singapore to develop and implement programmes that contribute to a healthy and engaged population in the Western part of Singapore.

About the National University Hospital
The National University Hospital is a tertiary hospital and major referral centre with over 50 medical, surgical and dental specialties, offering a comprehensive suite of specialist care for adults, women and children.

About Paxman
Paxman develops and offers the market leading Paxman Scalp Cooling System that is used to minimize hair loss in connection with chemotherapy treatment. Presently, the system is available at a large number of cancer centres in Europe, North- and South America, Asia and Australia. With more than 3,500 delivered systems to over 50 international markets, Paxman is the leading player in its field.

Scalp cooling treatment has a strong clinical support and is a fully established therapy in, for example, the UK, Scandinavia, the Netherlands, Belgium, Australia and a number of other countries.

Paxman was founded as a family business by Glenn Paxman following his wife Sue Paxman’s hair loss in connection with chemotherapy treatment for cancer. Glenn realized that there were shortcomings in the existing methods for scalp cooling and developed a liquid-based system together with his brother in its first version in 1996. Today, their son Richard Paxman is the CEO of Paxman, and their daughter Claire Paxman is Director of Strategic Initiatives. The Paxman Scalp Cooling System is a self-contained, mobile, and electrically powered cooling unit to which a specially designed cooling cap is connected. Each cooling unit has an integrated touch screen with a menu-controlled, graphic user interface that makes it easy for healthcare staff to initiate, monitor and complete the scalp cooling process. The associated Paxman cold cap is made from lightweight, biocompatible silicone that is soft and flexible, providing an optimal fit for the patient.

The use of scalp cooling is proven to be an effective way of combating CIA and can result in a high level of retention or can completely preserve the hair. For patients, this means the opportunity to regain some control, maintain their privacy, and encourage a positive attitude toward treatment.
