Birth Control Market Evolves as OTC Opill Hits US Stores

 The market for oral contraception is being turned upside-down as Perrigo has begun shipping Opill to thousands of retail stores nationwide, to be sold as the first over-the-counter birth control pill in the U.S.

The FDA approved Opill July 2023 as an OTC birth control option for patients 18 and older. Perrigo did not publicly release sales projections for the product, and The Motley Fool reported last July that the company is “quite unlikely” to generate $110 million per quarter—the value needed to “make a significant dent” in overall company revenues.

The current U.S. prescription birth control pill market is likely worth about $3 billion a year, Fady Boctor, president and CEO of men’s health company Petros Pharmaceuticals, estimated based on data showing that pills represent 37% of the $8 billion contraceptive market at large in the country.

For now it remains unclear how much money the new OTC option will siphon away from prescription contraceptives. “It will be interesting to see how does this over-the-counter access increase utilization” of oral contraception, Boctor told BioSpace.

The First OTC Birth Control Pill in the US

Opill is a daily tablet that contains 0.075 mg of norgestrel, a synthetic version of progesterone whose efficacy as a contraceptive was first established with the FDA’s 1973 approval of Pfizer’s Ovrette. Clinical trials showed Opill to be 98% effective at preventing pregnancy when taken as directed.

While Opill is the first OTC option in the U.S., it may not be the only one for long. Cadence OTC has an application in to make its Zena combination oral contraceptive over-the-counter. “The expectation is that [Opill] is just the first one,” said Robyn Elliott, an Annapolis, Md.–based healthcare lobbyist who consults for women’s health advocacy campaign Free the Pill. While no other companies have publicly disclosed their intentions to seek FDA approval at this time, “what is available over the counter in many, many other countries is a wide range of birth control pills. We would expect to see in the future more consideration of other options over the counter," Elliott told BioSpace

Historically, therapeutic classes have transformed from prescription-only to majority-OTC within a decade, noted David Spangler, senior vice president for legal, government affairs and policy at the Consumer Healthcare Products Association (CHPA). He said it took about four years for OTC to dominate the non-drowsy oral antihistamine market—think Claritin, Zyrtec and Allegra—and more than six years for steroid-based nasal allergy sprays like Flonase, Nasonex and Nasocort to make the transition. Heartburn drugs made the switch over a similar timeframe.

“Here [with birth control], you don’t know exactly how fast you’ll see other switches because the molecule matters,” Spangler told BioSpace.

Opill includes only norgestrel, a progestin, but no estrogen. Fortune Business Insights reported in 2018 that the majority of those on the pill worldwide chose combined progestin-estrogen options. Combination pills have different risk-benefit profiles than progesterone-only, Spangler said.

Boctor noted that due to its contraindications, a combination pill containing estrogen might necessitate consideration of a patient’s medical history, something that might slow the transition of the whole oral birth control market to OTC.

The Future of the Birth Control Pill Market

According to Statista, in 2022, 15% of U.S. adults who used contraception in the previous month chose oral birth control. But to this point, it has not been available without a prescription.

OTC conversions have boosted overall usage in other therapeutic classes by eliminating the time and cost needed to see a physician to obtain that prescription, not to mention potentially uncomfortable conversations about certain health conditions, Spangler said. But Boctor noted that Opill—along with anti-opioid treatment Narcan, which was approved for OTC sales a year ago—represent a “new horizon” of first-in-class compounds to make the OTC transition.

It has taken since approval last summer for Perrigo to ramp up manufacturing and distribution so Opill could appear on retail shelves, so it is too early to gauge sales. A representative from CVS Health told BioSpace that it began selling Opill through its website and CVS Pharmacy app on March 21 and is beginning to offer it in more than 7,500 stores nationwide this month. Other large retailers are also rolling it out.

Price may be a barrier for some Americans, however. Opill has a suggested retail price of $19.99 for a one-month pill pack, $49.99 for three months and $89.99 for a six-month supply containing 168 doses, according to Drugs.com, and no commercial insurer currently covers Opill unless legally required to, Verda Hicks, president of the American College of Obstetricians and Gynecologists, said in a statement. Free the Pill counts eight states that require insurance companies to cover OTC contraception. Not on the list is Wisconsin, where officials announced last month that the state’s ForwardHealth and BadgerCare Plus Medicaid programs will cover Opill, but no other carriers have announced coverage other than in the eight states with statutory mandates.

Perrigo said that it will soon launch a cost-assistance program to help uninsured and low-income Americans receive Opill for free, but the company is leaning on insurers to cover the product. “Perrigo strongly supports efforts to expand coverage for all OTC contraceptives, including Opill, under the Affordable Care Act,” Triona Schmelter, executive vice president of Perrigo and president of the Irish company’s consumer self-care division for the Americas, told BioSpace in an email.

AACR: Merck, Kelun’s Anti-TROP2 ADC Shows Early Promise in Gastric Cancer

 Preliminary Phase I/II data demonstrated that Merck and Kelun-Biotech’s TROP2-directed antibody-drug conjugate SKB264 can elicit promising disease control and even potentially extend survival among heavily pretreated patients with gastric or gastroesophageal junction cancer, according to an abstract presentation Tuesday at the 2024 American Association for Cancer Research annual meeting.

SKB264 achieved a 22% objective response rate in 41 patients who were evaluated for treatment response, nine of whom were partial responders. Disease control rate was 80.5%, with a median duration of response of 7.5 months.

In a subgroup of 24 patients who had been exposed to at least two prior lines of therapy and with more mature follow-up, SKB264 also appeared to boost survival. Median progression-free survival in this population was 3.7 months, while median overall survival (OS) reached 7.6 months. The 12-month OS rate was 32.6%.

SKB264 is an investigational antibody-drug conjugate (ADC) targeting the TROP2 cell surface protein, which is a well-validated target in gastric cancer and is associated with poor prognosis. The ADC’s toxic payload is a belotecan-derivative topoisomerase I inhibitor that causes DNA damage and triggers cell death.

The ADC also uses a novel linker that is cleaved by pH changes in the vicinity of the tumor and by enzymes inside the cancer cells, allowing the payload to exert its anti-cancer effect in a targeted manner.

“It is interesting to note the change in antitumor activity and safety profile that results from changing payloads and linkers, even among ADCs aiming at the same target,” Jordi Rodon, study lead author and associate professor of investigational cancer therapeutics at the MD Anderson Cancer Center, said in a statement.

“One of the big results of this trial is that, by using a different linker-payload combination, we did not see the interstitial lung diseases associated with other ADCs,” Rodon added.

MD Anderson Cancer Center said in Tuesday’s announcement that a global Phase III study is being planned to evaluate SKB264 in comparison to the current standard of care in patients with at least three prior lines of therapy in gastric or gastroesophageal junction adenocarcinomas.

Merck in 2022 exercised its option for worldwide rights—except in the Greater China region—to SKB-264, which aside from gastric cancer is also being assessed in a Phase III study for triple-negative breast cancer and in a Phase II trial for non-small cell lung cancer and other advanced tumors. Merck and Kelun, a subsidiary of China-based Sichuan Kelun Pharmaceutical, forged an oncology partnership shortly after.

'GLP-1s Like Novo Nordisk’s Ozempic Do Not Increase Thyroid Cancer Risk: Study'

 GLP-1 receptor agonists—a popular drug class that includes Novo Nordisk’s Ozempic (semaglutide) and Victoza (liraglutide)—do not appear to increase the risk of thyroid cancer, according to a new study published Wednesday in The BMJ.

The Scandinavian study, led by researchers at Swedish medical university Karolinska Institutet, drew from national registry data in Denmark, Norway and Sweden. The researchers looked at around 145,000 patients who had been treated with GLP-1s, primarily semaglutide and liraglutide, which is also sold by Novo under the brand name Saxenda. The study used data from more than 290,000 patients receiving other diabetes treatments, primarily DPP4 inhibitors.

Over an average follow-up of just under four years, patients treated with GLP-1 receptor agonists did not see a significantly higher risk of developing thyroid cancer. This result remained consistent when GLP-1 analogs were compared with SGLT2 inhibitors, another common class of diabetes medication.

“Our study covers a broad group of patients and provides strong support that GLP-1 analogues are not associated with an increased risk of thyroid cancer,” Björn Pasternak, principal researcher at the Department of Medicine at Karolinska Institutet, said in a statement.

At the same time, the researchers were quick to point out that their findings do not definitively establish that GLP-1 agents are completely free of thyroid cancer risk.

“We cannot rule out that the risk of certain subtypes of thyroid cancer is increased in smaller patient groups that we could not study here,” Peter Ueda, assistant professor at the Department of Medicine at Karolinska Institutet, said in a statement. Patients who are more susceptible to congenital medullary thyroid cancer, for instance, are “advised against using these drugs.”

GLP-1 receptor agonists are a top-selling class of diabetes and obesity medications that work by mimicking the GLP-1 hormone to induce the production and secretion of insulin from the pancreas. Novo’s semaglutide and Lilly’s tirzepatide currently dominate the GLP-1 space, with the two companies projected to control around 80% of the multibillion-dollar market by 2030.

Amid soaring demand, however, GLP-1s have been flagged for several potential safety issues. In July 2023, the European Medicines Agency (EMA) launched an investigation into the drug class over a potential association with thyroid cancer. A few months later, however, the regulator found no conclusive evidence to support the link.

GLP-1 therapies are also being reviewed for their potential risk of increasing suicidal ideation and self-harm. The EMA kicked off its probe in July 2023 and its Pharmacovigilance Risk Assessment Committee is scheduled to continue discussions this week.

The FDA in January 2024 also initiated an investigation into the suicidal ideation and self-harm risks of GLP-1 analogs, but a week later found no evidence to support such an association.

Alex Jones To Sue CIA After Undercover Report Claims Agency "Went After Him Hardcore"

 Infowars founder and host Alex Jones says he plans to sue the CIA following the release of an undercover sting in which an alleged CIA officer claims that the US intelligence community "took his [Jones's] money away" to "chop his legs off."

The employee, a CIA contracts officer in San Diego named Gavin O'Blennis, tells the undercover journalist: "You can kind of put anyone in jail if you know what to do," adding "You set ’em up. You create the situation to where they have no choice but to act on their impulse. And once they act on that impulse, some would call that entrapment."

"Nothing like putting out a fake social media thing to like really get people mad," O'Blennis continued.

When asked who the CIA has messed with, O'Blannis mentioned Alex Jones, implying that the agency was involved in Jones' lawsuit, and encouraged Sandy Hook families to sue.

"We just say ‘there’s no federal statute being broken but you have the option for a civil case and it’s a pretty good case in our opinion.’"

Jones to Sue

Following the release of the footage, Alex Jones told journalist Benny Johnson that he's going to sue the CIA.

"He needs to be subpoenaed by Congress," Jones said of O'Blennis. "I am planning to launch a lawsuit against the CIA and the FBI. We have to bring all this out and right as my bankruptcy comes to a close and right as all this stuff is being finalized it’s really God’s work working here that this came out at this time."

Jones says he's speaking with several lawyers to explore options. Watch:
