What is the purpose of this trial?

This trial tests a new approach to treating cardiac sarcoidosis, a heart condition that can cause heart rhythm problems and weakness. Researchers aim to determine if a lower dose of Prednisone (a medication used to reduce inflammation) combined with Methotrexate (another anti-inflammatory drug) is as effective as a higher dose of Prednisone alone, but with fewer side effects. Individuals diagnosed with active cardiac sarcoidosis and experiencing heart rhythm issues or heart weakness might be suitable candidates. Participants should not have received recent non-topical treatment for sarcoidosis or be currently taking Methotrexate or Prednisone for another condition. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to a potentially groundbreaking treatment.

Will I have to stop taking my current medications?

The trial requires that you are not currently taking Methotrexate or Prednisone for another health condition, and you must not have received non-topical treatment for sarcoidosis recently (within two months). If you are on these medications, you may need to stop them to participate.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that Methotrexate and Prednisone (or Prednisolone) have been studied for safety in treating sarcoidosis, including its impact on the heart. Methotrexate carries a lower risk of causing infections compared to azathioprine. One study found a 6.8% infection risk with Methotrexate over six months, compared to a 12% risk with azathioprine, suggesting Methotrexate is relatively safe for people with sarcoidosis.

Prednisone (or Prednisolone) is often used to treat heart-related sarcoidosis. It is effective, but high doses over a long period can cause side effects. The study aims to determine if using a lower dose with Methotrexate can reduce these side effects while maintaining effectiveness.

Overall, research supports that these treatments are generally well-tolerated. However, it is important to consult a doctor about any concerns before joining a trial. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for cardiac sarcoidosis because they explore different dosing strategies and combinations of existing medications to improve patient outcomes. Methotrexate, combined with varying doses of Prednisone or Prednisolone, offers a potentially more effective approach by using a lower steroid dose, which can reduce side effects. Additionally, the trial includes specific dosing adjustments for Japanese patients, acknowledging and addressing potential regional differences in drug metabolism and response. This tailored approach might lead to more personalized and effective treatment plans for patients with this challenging heart condition.

What evidence suggests that this trial's treatments could be effective for cardiac sarcoidosis?

In this trial, participants will receive either Prednisone (or Prednisolone) or Methotrexate as part of their treatment for cardiac sarcoidosis. Research has shown that prednisone, a type of steroid, effectively treats cardiac sarcoidosis and can help reduce long-term health problems in patients with good heart function. However, prednisone can cause serious side effects, especially at higher doses. Methotrexate, used in this trial alongside a reduced dose of prednisone, can help manage cardiac sarcoidosis. Studies suggest that methotrexate may help control the condition and lower the risk of recurrence. Using a lower dose of prednisone with methotrexate might provide effective treatment while reducing side effects. ^{6 7 8 9 10}

\[Dose everywhere except Japan\] Methotrexate 15-20 mg orally, sc, or IM once a week for 6 months + Prednisone 20 mg po daily for one month then 10 mg po daily for one month then 5 mg po daily for one month and then stop. Also Folic Acid OD (exact dose and directions at physicians discretion) for 6 months. \[Dose in Japan\] Methotrexate 5-20mg mg orally, sc, or IM once a week for 6 months+ Prednisone or Prednisolone 20mg OD for 1 month then 10mg OD for 1 month then 5 mg OD one month. Also Folic Acid 2 mg po daily for 6 months.

Group II: Prednisone (or Prednisolone) Active Control 1 Intervention

\[Dose everywhere except Japan\] Prednisone 0.5 mg kg/day for 6 months (max dose 30 mg) \[Dose in Japan\] Prednisone or prednisolone 0.5 mg/kg po (max 30mg) for one month then reduce by 5 mg per month for five months

Published Research Related to This Trial

Corticosteroids are commonly used to treat sarcoidosis, especially in cases involving cardiac, neurologic, or eye disease, but some patients may not respond well or may experience adverse effects.

Methotrexate and azathioprine are preferred alternative treatments for sarcoidosis due to their safety and efficacy, although there is no clear consensus on when to use these cytotoxic agents.

Glucocorticosteroids, particularly prednisolone at doses of 30-60 mg/day, are the primary treatment for sarcoidosis, with various administration routes available, including oral and inhaled options for pulmonary cases.

Other steroid-sparing medications like methotrexate and azathioprine can be effective alternatives, especially for patients requiring long-term treatment, which may last from 6 months to a lifetime depending on disease activity.

The CHASM CS-RCT is the first randomized controlled trial aimed at evaluating treatment strategies for cardiac sarcoidosis, comparing a low-dose prednisone/methotrexate combination to standard-dose prednisone in 194 patients with active cardiac involvement.

The study hypothesizes that the combination therapy will not only be equally effective but also improve patients' quality of life by reducing the side effects commonly associated with higher doses of prednisone.

In a trial involving 40 sarcoidosis patients treated with intramuscular triamcinolone acetonide (Kenacort A), the treatment showed a higher rate of improvement in chest findings compared to oral prednisolone, indicating its efficacy.

The intramuscular treatment also resulted in fewer side effects and a significant improvement in ocular lesions, suggesting it may be a safer alternative to oral corticosteroids.

In a study of 200 sarcoidosis patients, both methotrexate and azathioprine effectively reduced the need for prednisone, with 70% of patients achieving a decrease of at least 10 mg in their daily prednisone dose after one year.

While both treatments improved lung function, methotrexate and azathioprine had similar side effects, except that the azathioprine group experienced a higher rate of infections (34.6% vs 18.1%).

In a study of 61 newly diagnosed cardiac sarcoidosis patients, treatment with prednisone, methotrexate, or a combination of both led to significant reductions in myocardial FDG uptake, indicating effective metabolic response after 6 months.

No significant differences in clinical outcomes or major adverse cardiovascular events were observed among the treatment groups, suggesting that methotrexate may be a viable steroid-sparing option in managing cardiac sarcoidosis.

Prednisone vs methotrexate in treatment naïve cardiac sarcoidosis. Vis, R., Mathijssen, H., Keijsers, RGM., et al.[2023]

In a survey of 56 patients with pulmonary sarcoidosis, those taking prednisone reported significantly more side effects (78%) compared to those on methotrexate (49%), suggesting that methotrexate may be a safer alternative.

The study highlights the need for a larger prospective study to confirm these findings, as methotrexate appears to have fewer and less bothersome side effects than the first-line treatment, prednisone.
