Update on NovoRapid PumpCart Cartridges
The Department of Health and Social Care (DHSC) announced on June 4, 2025, that supplies of the NovoRapid PumpCart 1.6ml cartridges from Novo Nordisk will be limited throughout the year.
The NovoRapid (insulin aspart) PumpCart cartridges are utilized in the mylife YpsoPump insulin pump.
The scarcity may impact initiating new prescriptions for PumpCart cartridges. Diabetes care teams could review existing PumpCart users, with current users having the option to switch to insulin vials with disposable reservoirs. Alternative insulin products such as NovoRapid vials and mylife YpsoPump Reservoirs are recommended for those in need.
Patients transitioning to the mylife YpsoPump insulin pump filling system should ensure to access vials and reservoirs for seamless continuity of care.
Close monitoring of glucose levels is recommended after changing treatment methods, and it is advisable to consult the diabetes care team if necessary. Novo Nordisk will discontinue Levemir insulin by the end of 2026, so prescribing Levemir and switching patients to alternatives should be avoided until further guidance is provided. While NovoRapid FlexTouch pens have been discontinued, alternative options like NovoRapid FlexPen and Trurapi are still available. The discontinuation of Insulatard Penfill cartridges by mid-2025 will see Humulin I KwikPen as a replacement. Patients using discontinued pre-filled insulin devices like Insulatard Innolet can opt for alternatives such as Humulin I KwikPen. Although a shortage of Fiasp FlexTouch pens is expected until January 2026, Penfill cartridges will remain accessible. Tresiba FlexTouch pens are likely to be unavailable until January 2026; however, Penfill cartridges remain an option. It is essential to become familiar with new injection pens and monitor blood sugar levels closely when initiating a new insulin device. Stakeholders are urged to consider patient needs during insulin transitions and provide the necessary prescriptions. The introduction of insulin has transformed diabetes treatment, but affordability remains a significant barrier. Taking steps to address insulin affordability is crucial.
Innovation and progression in insulin therapy have made significant strides over the past century. The evolution from animal-derived to genetically engineered human insulin in the 1980s marked a pivotal moment in diabetes treatment. Subsequent decades ushered in new formulations like rapid-acting and long-acting insulin analogs, as well as innovative delivery methods such as insulin pens and pumps. Ongoing efforts aim to enhance insulin pharmacokinetics, simplify treatment, and reduce side effects through the development of novel insulin types. Technological advancements have also led to improved insulin delivery and monitoring with continuous glucose monitoring (CGM) systems and artificial pancreas systems. Despite these advancements, rising insulin prices pose challenges to accessibility and affordability, particularly in low- and middle-income countries. Enhancing the availability and affordability of insulin is essential for effective diabetes management.
Amidst the rising costs of insulin, especially due to expensive insulin analogs, affordability remains a significant concern for individuals. The escalating prices have led to challenges in adherence to treatment regimens, with many individuals skipping or rationing insulin doses to cope with the high costs. Policies affecting medication costs, such as cost-sharing features, can further impede medication use and adherence, particularly among low-income populations. Addressing cost-sharing barriers and promoting transparency in drug pricing are crucial steps towards making diabetes medications more affordable and accessible. Efforts to introduce generic drugs, shorten market exclusivity periods, and eliminate anticompetitive practices can help lower medication costs for individuals with diabetes. Enhancing transparency in drug pricing and empowering the federal government to negotiate drug prices are crucial strategies for improving medication affordability.
Generic drugs offer a lower-cost alternative to brand-name medications, contributing to significant cost savings in the healthcare system. The introduction of biosimilar insulins, although slow, provides a more affordable option for diabetes treatment. Strategies to enhance competition, timely availability of generics, and transparency in drug pricing negotiations are necessary to control prescription drug costs effectively. Legislative measures, such as those implemented in Medicare Part D, promote competition among private plans to lower drug prices. The role of pharmacy benefit managers in managing drug costs for Medicare Part D underscores the importance of increased transparency in rebates utilization. Medicare Part D beneficiaries face high insulin costs due to the absence of generic alternatives, necessitating the need for more affordable options and lower-cost insulin analogs.
Improving access to insulin involves controlling costs through the prescription of lower-cost options, the introduction of biosimilars, and increasing flexibility in price negotiations. Healthcare providers should weigh the costs of newer insulin analogs and consider recommending lower-cost alternatives like Human NPH and regular insulins available at discounted prices. Addressing weak competitive pressures and discouraging anticompetitive practices can help lower insulin prices and improve accessibility. Policies should aim to reduce market exclusivity for biological products and discourage multiple patents on a single drug to foster competition and improve access. Emphasizing transparency in drug pricing is crucial to eliminate distortions that impact patients negatively and ensure equitable access to essential medications like insulin.
SUMMARY
Improving access to medications and ensuring costs are aligned with benefits can be achieved through value-based pricing and insurance design. By simplifying pricing based on outcomes and clinical measures, patients can more easily obtain the medications they need.
Part D Senior Savings Model
Addressing regulatory barriers that limit value-based pricing is crucial. Innovative models such as the Part D Senior Savings Model, which reduces out-of-pocket costs for insulin, can greatly benefit Medicare beneficiaries with diabetes.
Insulin, a key treatment for diabetes, has had a significant impact on the lives of those with the condition. Despite its importance, nearly half of the global diabetic population requiring insulin cannot access or afford it, with a significant portion in the United States facing financial challenges that lead to rationing or skipping doses.
To address these disparities and ensure access to insulin, collaboration among various stakeholders is essential. Government agencies, professional organizations, pharmacy benefit managers, and insulin manufacturers must work together to improve availability and affordability. Strategies such as adopting lower-cost options, facilitating biosimilar insulins, and promoting transparency in drug pricing can all contribute to making insulin more accessible to those in need.
It is important for both healthcare providers and patients to consider the costs and benefits of insulin therapy. Collaboration and implementing value-based pricing can help ensure that all individuals with diabetes have access to this essential medication, reducing the risks of complications and premature death associated with underuse due to financial constraints.
