Overcoming Fear by Continuing His Fight

A white chalk mark

Hello, my name is Ron. I have relapsing-remitting multiple sclerosis (RRMS), but that doesn’t stop me from expressing myself. I like to say that my life has been a 3-round fight.

I took advantage of an opportunity to attend vocational training while still in high school and studied HVAC (heating, ventilation, air-conditioning). This became my career, and I loved all of the action. However, during the summer heat, I remember experiencing bouts of extreme fatigue. That fatigue showed up late in round 1 and that fatigue caused me to fall asleep at the wheel and roll my pickup on the highway. When it finally came to a rest, I was hit by an 18-wheeler and both trucks exploded in flames. I survived that round without spending a single night in the hospital, by what I believe was divine intervention. The accident that could have left me physically paralyzed instead left me paralyzed with fear.

I believe that all your life you will either be paralyzed by your fear or propelled by your faith. This began my lifelong battle of fear versus faith.

For the next 25 years, I worked and advanced in my career, all while experiencing extreme fatigue and right-side weakness. Several doctor visits over the years did not reveal a reason for the fatigue or weakness. Eventually, I reached the level of Operations Manager with a telecommunications giant. The demands were nonstop, and my pager and cell phone went off 24/7. Midway through 2008, I began tripping over unseen obstacles as I walked. I didn’t think much of it. But then on December 31 of that year, my right arm went limp, and I lost control of it. I thought I was having a heart attack or ministroke and contacted my primary doctor, who ruled out anything serious. She advised me to see a neurologist who did an MRI and CT scan. Two weeks later, everything changed. My neurologist called me into her office and told me I had relapsing multiple sclerosis. I freaked out. I thought MS was a death sentence. My neurologist advised me to start therapy as soon as possible, and I complied.

In the closing moments of round 2, while I was still intoxicated with fear, my sister was also diagnosed with MS. Greatly concerned about her, I knew that I would be no help to her still bogged down with fear. I thought about one of the survivors of the Titanic. When they were celebrating her 100th birthday, they asked her the secret of her longevity. Do you know what she replied? “When the ship began to sink, I got off.” And that’s what I did. I decided to get off the ship of fear and board the life raft of faith. I left fear behind and began taking a more active role in my healthcare. I realized that fear—not MS—was the bigger enemy.

The bell sounded and I headed into round 3. I knew that I needed to make some changes if wanted to win this fight. First, I changed doctors, because I wanted to be under a neurologist that specialized in MS. Secondly, I changed support groups because my first group seemed to be hosting their own pity party. I needed to be surrounded by positivity. Lastly, my doctor and I decided that I would try a new treatment when it became harder to remain compliant to my first therapy due to unwelcome side effects and the lack of motivation to stay consistent. Traveling with this treatment became burdensome as well.

Making this change was possible because I was able to express my feelings and concerns with my neurologist.

My neurologist made me aware that MAVENCLAD® (cladribine) tablets was close to being approved in the United States. I was particularly drawn to the convenient dosing schedule. We discussed the screening and monitoring that would be required before, during, and after treatment, as well as the serious side effects of MAVENCLAD, including the risk of cancer, low white blood cell counts, serious infections, and liver problems. Once we found out MAVENCLAD was approved, we agreed it might be a good option for me.

So, I scheduled my first treatment with MAVENCLAD. I admit I was a little nervous, but I contacted my neurologist, and he was able to reassure me. I share this with you because it is so important to reach out to your doctor whenever you have concerns. With that said, so far, my experience with MAVENCLAD has been positive. MAVENCLAD has afforded me the pleasure of getting up and not having to remember to take a shot, which is big in my book. The dosing gave me more flexibility to travel and spend time with my friends and family, because I no longer had to schedule my life around the injections. However, I have had occasional headaches, but my doctor advised me to manage them by taking an over-the-counter pain reliever.

Of course, my fight with MS is not done. I’ll always be in the ring with this opponent, but I’m not fighting alone. With support from my family, my neurologist, and a treatment that works well for me, I’m determined to stay in the ring and keep expressing myself with strength.

Indication and Important Safety Information

WHAT IS MAVENCLAD?

MAVENCLAD is a prescription medicine used to treat relapsing forms of multiple sclerosis (MS), to include relapsing-remitting disease and active secondary progressive disease, in adults. Because of its safety profile, MAVENCLAD is generally used in people who have tried another MS medicine that they could not tolerate or that has not worked well enough.

MAVENCLAD is not recommended for use in people with clinically isolated syndrome (CIS).

It is not known if MAVENCLAD is safe and effective in children under 18 years of age and is therefore not recommended.

IMPORTANT SAFETY INFORMATION
MAVENCLAD may cause serious side effects, including:
  • Risk of cancer (malignancies). You should follow healthcare provider instructions about screening for cancer.
  • MAVENCLAD may cause birth defects if used during pregnancy. Women must not be pregnant when they start treatment with MAVENCLAD or become pregnant during MAVENCLAD dosing and within 6 months after the last dose of each yearly treatment course. You should stop treatment with MAVENCLAD and contact your healthcare provider right away if you become pregnant during treatment with MAVENCLAD.
    • For women who are able to become pregnant:
      • Your healthcare provider should order a pregnancy test before you begin your first and second yearly treatment course of MAVENCLAD to make sure that you are not pregnant.
    • Ask your healthcare provider which contraceptive method is right for you. Women and men being treated with MAVENCLAD should use effective birth control (contraception) on the days on which they take MAVENCLAD and for at least 6 months after the last dose of each yearly treatment course.
Do not take MAVENCLAD if you:
  • have cancer (malignancy).
  • are pregnant, plan to become pregnant, or are a woman of childbearing age or a man able to father a child and you are not using birth control.
  • are breastfeeding.
  • are human immunodeficiency virus (HIV) positive.
  • have active infections, including tuberculosis (TB), hepatitis B or C.
  • are allergic to cladribine.
Before you take MAVENCLAD, tell your healthcare provider about all of your medical conditions, including if you:
  • think you have an infection.
  • have taken, take, or plan to take medicines that affect your immune system or blood cells, or other treatments for MS. Certain medicines can increase your risk of getting an infection.
  • have had a recent vaccination or are scheduled to receive any vaccinations. You should not receive live or live-attenuated vaccines within the 4 to 6 weeks preceding treatment with MAVENCLAD or receive these types of vaccines during your treatment with MAVENCLAD and unless directed by your healthcare provider.
  • have heart failure.
  • have or have had cancer.
  • have liver or kidney problems.
  • are breastfeeding or plan to breastfeed. It is not known if MAVENCLAD passes into your breast milk. Do not breastfeed on the days on which you take MAVENCLAD, and for 10 days after the last dose.
How should I take MAVENCLAD?
  • MAVENCLAD is given as two yearly treatment courses, consisting of 2 treatment weeks (cycles) about a month apart.
  • Handle MAVENCLAD with dry hands and take immediately after opening the blister pack. Take with water and do not chew the tablet. MAVENCLAD can be taken with or without food and should be taken at least 3 hours apart from other medicines.
  • Wash your hands after handling MAVENCLAD. Limit contact with your skin (especially on your face). Wash skin and surfaces with water if contact occurs.
  • If you miss a dose, take it as soon as you remember on the same day. If the whole day passes before you remember, take your missed dose the next day. Do not take 2 doses at the same time. Instead, you will extend the number of days in that treatment week.

Your healthcare provider will continue to monitor your health during the 2 yearly treatment courses, and for at least another 2 years during which you do not need to take MAVENCLAD. It is not known if MAVENCLAD is safe and effective in people who restart MAVENCLAD treatment more than 2 years after completing 2 yearly treatment courses.

MAVENCLAD can cause serious side effects. If you have any of these symptoms listed below, call your healthcare provider right away:
  • low blood cell counts have happened and can increase your risk of infections during treatment with MAVENCLAD. Blood tests are needed before you start treatment with MAVENCLAD, during your treatment with MAVENCLAD, and afterward, as needed.
  • serious infections such as:
    • life-threatening or fatal infections caused by bacteria, viruses, parasites or fungi.
    • TB, hepatitis B or C, and shingles (herpes zoster). Fatal cases of TB and hepatitis have happened with cladribine during clinical studies. Tell your healthcare provider right away if you get any symptoms of the following infection related problems or if any of the symptoms get worse, including fever, aching painful muscles, headache, feeling of being generally unwell, loss of appetite, burning, tingling, numbness or itchiness of the skin in the affected area, skin blotches, blistered rash, or severe pain.
    • progressive multifocal leukoencephalopathy (PML). PML is a rare brain infection that usually leads to death or severe disability. Although PML has not been seen in MS patients taking MAVENCLAD, it may happen in people with weakened immune systems. Tell your healthcare provider right away if you have any new or worsening neurologic signs or symptoms. These may include: weakness on 1 side of your body, loss of coordination in your arms and legs, decreased strength, problems with balance, changes in your vision, changes in your thinking or memory, confusion, or changes in your personality.
  • liver problems. Symptoms of liver problems may include: nausea, vomiting, stomach pain, tiredness, loss of appetite, dark urine, or your skin or the whites of your eyes turn yellow. Your doctor will perform blood tests to check your liver during treatment.
  • allergic reactions (hypersensitivities). You should stop treatment and seek immediate medical attention if any signs or symptoms of allergic reactions occur. Symptoms of an allergic reaction may include skin rash, swelling or itching of the face, lips, tongue or throat, or trouble breathing.
  • heart failure. MAVENCLAD may cause heart failure, which means your heart may not pump as well as it should. Call your healthcare provider or go to the closest emergency room for medical help right away if you have any signs or symptoms such as shortness of breath, a fast or irregular heart beat, or unusual swelling in your body.

The most common side effects of MAVENCLAD include: upper respiratory infection, headache, and low white blood cell counts.
