FDA Issues Boxed Warning for Osteoporosis Drug Denosumab (Prolia)

In a recent development, the Food and Drug Administration (FDA) has taken a significant step by adding a boxed warning to the label of the osteoporosis drug denosumab, commonly known as Prolia. This warning specifically addresses the potential risk of severe hypocalcemia in patients with advanced chronic kidney disease (CKD), as announced by the agency on a recent Friday.
The decision to implement this boxed warning follows a comprehensive review of available evidence, including fresh data published in the Journal of the American Medical Association (JAMA). Based on their analysis, the FDA has concluded that denosumab carries an increased risk of severe hypocalcemia, particularly when compared to bisphosphonates, in patients with advanced CKD, particularly those undergoing dialysis. It is important to note that patients on dialysis or suffering from mineral and bone disorder (MBD) are at the highest risk of experiencing significantly low blood calcium levels.
The newly acquired data, primarily involving women undergoing dialysis, revealed alarming statistics. Approximately 41% of patients developed severe hypocalcemia within the initial 12 weeks of denosumab treatment, in stark contrast to only 2.0% of those who were prescribed oral bisphosphonates.
The boxed warning, described by the FDA as the “most prominent” warning, serves as a cautionary notice about the potential for severe harm arising from severe hypocalcemia. This harm could manifest as hospitalization, life-threatening events, and even fatalities among patients with advanced CKD who are using denosumab. Symptoms of severe hypocalcemia may vary from being asymptomatic to presenting with confusion, seizures, irregular heart rhythms, fainting, facial twitches, uncontrolled muscle spasms, or sensations of weakness, tingling, or numbness in specific body areas.
As part of their latest communication on drug safety, the FDA has advised healthcare professionals to exercise utmost caution in selecting appropriate candidates for denosumab treatment. Furthermore, they recommend intensified monitoring of blood calcium levels, especially during the initial 2 to 10 weeks following each injection. In some cases, patients may also require calcium and vitamin D supplements to manage their condition effectively.
Before prescribing denosumab, healthcare providers are strongly encouraged to assess their patients’ kidney function and carefully consider the risk of severe hypocalcemia in the context of other available osteoporosis treatment options for patients with advanced CKD, particularly those undergoing dialysis.
The FDA underscores the importance of patients not discontinuing their denosumab medication without first consulting their healthcare provider. Abruptly ceasing treatment may have adverse consequences, and patients are advised to seek professional guidance in this matter.
This label update by the FDA follows an initial safety alert issued in November 2022, which highlighted the potential risk of hypocalcemia associated with denosumab in women dependent on dialysis. The alert was prompted by interim findings from Amgen, the manufacturer of denosumab, as part of an ongoing safety study that indicated an elevated risk of hypocalcemia in patients with advanced kidney disease.
Originally approved in 2010 for postmenopausal women at high risk of bone fracture due to osteoporosis, denosumab has expanded its indications over time. It is now used to treat osteoporosis in men, glucocorticoid-induced osteoporosis, bone loss in patients receiving androgen-deprivation therapy for prostate cancer, and in women undergoing aromatase inhibitor therapy for breast cancer. Additionally, it is approved under the trade name Xgeva to reduce the risk of bone-related events in specific cancer patients.
Administered via injection every six months, denosumab functions by inhibiting the protein receptor activator of nuclear factor kappa beta (RANK), thereby preventing the breakdown of bone by osteoclasts in the body.
The FDA encourages both patients and healthcare professionals to promptly report any side effects related to denosumab to their MedWatch program, ensuring that concerns are addressed and safety is prioritized.
Filing Your Denosumab Hypocalcemia Lawsuit
If you or a loved one have experienced adverse effects or harm from denosumab (Prolia), it is crucial to seek legal guidance to understand your rights and options. Victims of such pharmaceutical issues may have grounds for legal action to seek compensation for their injuries. Product liability lawsuits can hold manufacturers accountable for producing and distributing defective drugs that cause harm to consumers.
The process of pursuing a product liability lawsuit is intricate and often necessitates the expertise of an attorney at each stage to ensure a favorable outcome. Here is an overview of the steps involved and the reasons why legal representation is crucial:
- Consultation: Victims should initiate a consultation with an attorney specializing in product liability cases. During this initial meeting, the attorney will evaluate the merits of the case and provide insights into the best course of action.
- Investigation: Attorneys will conduct a thorough investigation to gather evidence establishing the drug’s defect, its link to the injuries sustained, and the extent of damages suffered by the victim.
- Filing the Lawsuit: Once sufficient evidence is gathered, the attorney will file a product liability lawsuit against the drug manufacturer, in this instance, the maker of denosumab.
- Discovery: The discovery phase involves exchanging information between both parties. The manufacturer’s defense team will present their evidence, while the victim’s attorney continues to build their case.
- Negotiation or Trial: In some instances, negotiations may take place to reach a settlement. If an agreement cannot be reached, the case proceeds to trial, where a judge or jury determines liability and potential damages.
- Damages: In the event of a successful lawsuit, victims may be entitled to various forms of compensation, including medical expenses, lost income, pain and suffering, and punitive damages.
Legal representation is paramount at each step of this complex process, as attorneys possess the necessary expertise to navigate legal intricacies, advocate for the victim’s rights, and ensure they receive fair compensation for their suffering.
The FDA’s decision to issue a boxed warning for denosumab (Prolia) underscores the gravity of the situation and the potential harm this drug can cause.
