Taro to Make Keveyis™ Available to Distributors Free of Cost

Effort Seeks to Address Needs of People with Periodic Paralysis, an Ultra Rare Disease

HAWTHORNE, N.Y.--(BUSINESS WIRE)--May 2, 2016-- Taro Pharmaceutical Industries Ltd. (NYSE:TARO) (“Taro” or the “Company”) today announced that its U.S. subsidiary, Taro Pharmaceuticals U.S.A., Inc., will now make Keveyis™ (dichlorphenamide) available to distributors at no cost for the treatment of primary periodic paralysis, an ultra-rare and debilitating disease. As a result, Taro will cease commercial sales and related promotional activities for Keveyis and bear all costs associated with its manufacture. In the near term, patients will continue to receive the medicine through Diplomat as the Company evaluates the best option for keeping pharmacy dispensing fees to patients as low as possible.

“We embarked on this decade-long journey to help a patient community in need and we are proud that it resulted in Keveyis, the first medicine approved for the treatment of periodic paralysis,” said Kal Sundaram, Chief Executive Officer of Taro USA. “Through heartfelt testimonials, patients have told us how their lives have changed for the better thanks to this treatment being available. This decision extends our desire to ensure that anyone with a prescription will continue to have access to the medicine regardless of insurance status or ability to pay.”

In establishing the original price for Keveyis, Taro sought to balance the investment needed to educate the patient and physician community about a largely unknown disease while also ensuring that access to patients wasn’t hindered. Through its Keys2Care support program, patients have had an average out-of-pocket cost of less than $25 per month. For some, treatment has been free through the Company’s Patient Assistance Program.

Although Taro expected to treat only a few hundred patients with Keveyis, it has become clear that reaching such a small pool of people is more difficult than previously anticipated. Among the 5,000 people estimated to be living with Periodic Paralysis, less than 1,500 are believed to be diagnosed.[1] Among these patients, a mix of lifestyle modifications and medicines prescribed off-label are often used to manage their disease. While we have continued to invest significantly in this effort, sales have been less than one million dollars since launch.

Given the high costs and resources required to identify and reach a limited number of viable patients, Taro realizes that it cannot sustain its current level of investment. Based on these learnings, Taro now believes that it can better serve all stakeholders, including patients, by ceasing commercial sales and related promotional activities for Keveyis.

About Periodic Paralysis

Periodic paralyses are a group of rare hereditary disorders that cause episodes of muscle weakness or paralysis. Many patients often endure decades of diagnostic ‘missteps,’ with a significant delay between the onset of symptoms and diagnosis.[2][3] Types of periodic paralyses are differentiated by criteria including underlying genetic mutations and changes in blood-potassium during attack. Hypokalemic and hyperkalemic are two common types of periodic paralyses.[4]

About Keveyis

Keveyis is indicated for the treatment of primary hyperkalemic periodic paralysis, primary hypokalemic periodic paralysis, and related variants.


In clinical studies, the most common side effects of Keveyis were a burning or pricking sensation, difficulty thinking and paying attention, changes in taste, and confusion. These are not all of the possible side effects that you may experience with Keveyis. Talk to your doctor if you have any symptoms that bother you or do not go away.

Keveyis is not for everyone. Do not take Keveyis if you:

  • Are on a high-dose aspirin regimen
  • Are allergic to sulfa-based drugs
  • Have liver, kidney, or certain lung conditions
  • Are pregnant, planning to become pregnant, or nursing
  • Are under 18 years old

Taking Keveyis may cause a drop in the amount of potassium (an electrolyte) in your body, which can lead to heart problems. Ask your doctor if you need to eat foods that contain high amounts of potassium while taking Keveyis.

Your body may produce too much acid or may not be able to remove enough acid from body fluids while taking Keveyis. Your doctor will run tests on a regular basis to check for signs of acid buildup and may reduce your dose or stop your treatment with Keveyis.

Keveyis may also increase the risk of falls, especially in elderly patients and patients taking high doses of Keveyis. Use caution when driving, operating machinery, or performing any other hazardous activities while taking Keveyis, as this medication may cause drowsiness.

Tell your doctor if you experience worsening of your periodic paralysis symptoms.
