Analyst report notes that Gilead’s hep C cure will make less than $4 billion this year.

One-shot cures for diseases are not great for business—more specifically, they’re bad for longterm profits—Goldman Sachs analysts noted in an April 10 report for biotech clients, first reported by CNBC.

The investment banks’ report, titled “The Genome Revolution,” asks clients the touchy question: “Is curing patients a sustainable business model?” The answer may be “no,” according to follow-up information provided.

Analyst Salveen Richter and colleagues laid it out:

Goldman Sachs wrote:The potential to deliver “one shot cures” is one of the most attractive aspects of gene therapy, genetically engineered cell therapy, and gene editing. However, such treatments offer a very different outlook with regard to recurring revenue versus chronic therapies... While this proposition carries tremendous value for patients and society, it could represent a challenge for genome medicine developers looking for sustained cash flow.

For a real-world example, they pointed to Gilead Sciences, which markets treatments for hepatitis C that have cure rates exceeding 90 percent. In 2015, the company’s hepatitis C treatment sales peaked at $12.5 billion. But as more people were cured and there were fewer infected individuals to spread the disease, sales began to languish. Goldman Sachs analysts estimate that the treatments will bring in less than $4 billion this year.

Goldman Sachs wrote: “[Gilead]’s rapid rise and fall of its hepatitis C franchise highlights one of the dynamics of an effective drug that permanently cures a disease, resulting in a gradual exhaustion of the prevalent pool of patients,” the analysts wrote. The report noted that diseases such as common cancers—where the “incident pool remains stable”—are less risky for business.
