Enthusiastic Response
Other experts in the lipid field are also enthusiastic about new developments in the PCSK9s.
Jorge Plutzky, MD, director of preventive cardiology at Brigham and Women’s Hospital in Boston, said he welcomes the prospect of new approaches to PCSK9 inhibition.
“The increase in the number of safe, effective tools for LDL lowering, whether through PCSK9 or other targets, is inevitably beneficial for patients and the field,” he said during an interview.
Dr. Plutzky pointed out that although the current agents are effective, cost and coverage remain issues despite some recent progress in these areas, and new agents will increase competition and should hopefully drive prices down. Having a variety of dosing methods and frequencies provides more options for patients to find the one that works best for them.
Lerodalcibep’s once-monthly dosing schedule and the lack of need for refrigeration may be appreciated by some patients, he said, particularly those who need to travel for long periods.
Connie Newman, MD, adjunct professor of medicine at NYU School of Medicine, New York City, said there is plenty of room in the market to accommodate patient’s needs and preferences.
“Despite the US FDA approval of three medications that target PCSK9, there is a need for more anti-PCSK9 agents that reduce LDL and cardiovascular events,” she said. “In the US alone, 25% of adults have LDL levels of 130 mg/dL and above. Of all the non-statin therapies, medications targeting PCSK9 produce the greatest reduction in LDL. However, some patients may not tolerate one or more of the medications available or may prefer a monthly injection of lower volume.”
Dr. Newman said she believes there will still be a market for injectable formulations of PCSK9 inhibitors in the future, even if oral formulations are approved.
“Oral formulations usually require more frequent administration. Some people prefer longer-acting medications that can be taken less often. This might lead to better adherence,” she said.
Dr. Stein said he agrees there will always be room for different options. “And you only have to look at what is happening with the weight loss drugs to see that there is a market for injectables.” The ability to get patients to the new, more aggressive LDL goals is what is important, he added. “These drugs do that, and offering patients a choice of agents and delivery mechanisms is helpful.”
