The Janssen Pharmaceutical Companies of Johnson & Johnson announced today that the United States Food and Drug Administration (FDA) approved Ponvory™ (ponesimod) for the treatment of relapsing forms of multiple sclerosis (MS) in adults – including clinically isolated syndrome, relapsing-remitting, and active secondary-progressive forms of MS. This new disease-modifying therapy (DMT) is taken orally (by mouth) once daily and has been shown to reduce annual relapse rates and reduce disease activity as shown on magnetic resonance imaging (MRI), compared to treatment with an approved DMT, Aubagio® (teriflunomide). Ponvory should be available by prescription in April 2021.

In addition to its proven efficacy, Ponvory is well-tolerated and provides some additional benefits, such as its quick rate of leaving the blood system should the medication need to be stopped. The most common side effects include upper respiratory tract infections, elevated liver enzymes, and high blood pressure. Those with certain heart conditions, or women who are planning to be or are currently pregnant, should not take Ponvory.

Study Findings and How Ponvory Works

The approval of Ponvory was partly based on a two-year, head-to-head Phase III clinical trial, where the efficacy, safety, and tolerability of Ponvory (20 mg taken orally, once per day) was compared to Aubagio® (teriflunomide), which was taken in oral doses of 14 mg once daily. Referred to as the OPTIMUM trial (Oral Ponesimod Versus Teriflunomide in Relapsing Multiple Sclerosis), this study included 1,133 participants and found the following results for treatment with Ponvory when compared to Aubagio:

• 30.5% lower annual relapse rate
• 71% of participants had no confirmed relapses, compared to 61% in the Aubagio group
• The number of new gadolinium-enhancing (GdE) T1 lesions and the number of new or enlarging T2 lesions were reduced by 59% and 56% respectively
• Worsening disability was prevented for most people, although the differences in rates between the two medications were not significant

Ponvory is a selective sphingosine-1-phosphate receptor (S1P) modulator that is believed to work by keeping immune cells called lymphocytes out of the blood by trapping them in the lymph nodes. Lymphocytes that circulate in the blood and cross the blood-brain barrier to enter the central nervous system are thought to cause the damage to nerves seen in MS. Other approved sphingosine-1-phosphate (S1P) receptor modulators for MS include Gilenya® (fingolimod), Mayzent® (siponimod), and Zeposia® (ozanimod).

Should this medication need to be stopped at any time, it leaves the blood within one week, and the effects on the immune system wear off in one to two weeks for most patients. This is of benefit for people who may be waiting to get a vaccine, who plan to become pregnant, or who need to stop the medication for any other reason.

According to Johnson & Johnson, “Ponvory does not require genetic testing or first-dose cardiac monitoring for most patients. Because initiation of Ponvory treatment results in a decrease in heart rate, first-dose monitoring is recommended in patients with certain preexisting cardiac conditions.”

Side Effects and Adverse Events

As noted earlier, the most common side effects include upper respiratory tract infections, elevated liver enzymes, and high blood pressure. Adverse effects can include more serious infections and a slowed heart rate (bradycardia or bradyarrhythmia) when starting Ponvory. To help minimize the potential for initial side effects, patients begin taking Ponvory in a titrated “starter pack” for the first 14 days. The starter pack begins with a low dose and gradually increases to the full dose approved by the FDA.

Ponvory lowers the number of white blood cells (lymphocytes) in the blood. This medication also increases the risk of infection, including serious infection that can be life-threatening. To monitor the risk, individuals should have a recent blood test prior to starting the medication, and while taking the medication, should watch for signs of infection, such as fever, body aches, nausea, and headache, among others.

Since Ponvory can affect the heart rate, individuals need an electrocardiogram (ECG) to check the electrical activity of their heart before taking the first dose. People with certain cardiac conditions, such as those who have had a heart attack or stroke, or those experiencing angina, heart failure, or abnormal heartbeat, should not take Ponvory.

Those pregnant or planning to become pregnant, or who are breastfeeding, should not take Ponvory. Individuals are advised to tell their doctor about any health condition prior to starting this medication.

For More Information

In the coming days, the makers of Ponvory will have two programs available to the MS community. The first is Janssen CarePath, which will offer support and information on insurance coverage, potential costs, and options for making treatment more affordable. The second is the Wellness Companion Program, which provides one-on-one education to help patients get started and continue treatment. Contact information will be provided in an update to this article.
