COVID-19: Letter from Sun Pharmaceutical Industries

YONSA® is the first and only micronized abiraterone acetate formulation approved by the FDA, when used in combination with methylprednisolone. The advanced technology used in the formulation of YONSA® reduces abiraterone acetate particle size down to 200 to 800 nanometers in diameter2

Proprietary YONSA®
micronization provides:

  • No food restrictions1

    YONSA® gives patients the flexibility to take it with or without food2
  • Increased absorption

    Because a greater part of the active drug is getting absorbed, YONSA® is given as a 500 mg dose (four 125 mg tablets) taken once daily in combination with 4 mg methylprednisolone twice daily1,3
  • Similar bioavailability1

    YONSA®, in combination with 4 mg methylprednisolone, provides similar bioavailability to 1000 mg of abiraterone acetate with corticosteroid at a 500 mg dose.

YONSA® is the first and only micronized formulation of abiraterone acetate

 

 

Micronization increases the particle’s surface area and enables more rapid dissolution and absorption; this results in3:

  • A 500 mg dose (four 125 mg tablets plus two 4 mg methylprednisolone)1

YONSA® is the only abiraterone acetate with no food restrictions1

YONSA® gives patients dosing administration flexibility

  • YONSA®, taken in combination with methylprednisolone, is the only abiraterone acetate with no food restrictions, giving patients the flexibility to take it with or without food1,2
  • The formulation was designed to improve oral bioavailability and reduce food effects3

Only YONSA® is FDA-approved to treat mCRPC at a 500 mg dose1

  • YONSA® 500 mg (four 125 mg tablets) is administered orally once daily in combination with oral methylprednisolone (4 mg per dose twice daily)1
Tablets not to scale.

Dose modification

  • For patients with baseline moderate hepatic impairment (Child-Pugh Class B), reduce the YONSA® starting dose to 125 mg once daily1
  • For patients who develop hepatotoxicity during treatment, hold YONSA® until recovery. Retreatment may be initiated at a reduced dose. YONSA® should be discontinued if patients develop severe hepatotoxicity1

YONSA® 500 mg, in combination with 4 mg methylprednisolone, provides similar bioavailability to the 1000 mg dose of another abiraterone acetate taken in combination with a corticosteroid

YONSA® may not be interchangeable with other abiraterone acetate products. To avoid substitution errors and overdose, be aware that YONSA® tablets may have different dosing and food effects than other abiraterone acetate products.1

In patients with mCRPC who received prior docetaxel chemotherapy:

    • A total of 1195 patients were randomized 2:1 to receive either abiraterone acetate orally at a dose equivalent to 500 mg of YONSA® once daily in combination with a different corticosteroid orally twice daily (N=797) or placebo once daily plus a different corticosteroid orally twice daily (N=398). Patients randomized to either arm were to continue treatment until disease progression (defined as a 25% increase in prostate-specific antigen [PSA] over the patient’s baseline/nadir together with protocol-defined radiographic progression and symptomatic or clinical progression), initiation of new treatment, unacceptable toxicity, or withdrawal

 

  • Significant improvement in overall survival was seen among patients receiving abiraterone acetate at a dose equivalent to YONSA® 500 mg once daily in combination with methylprednisolone twice daily vs placebo1

IMPORTANT SAFETY INFORMATION

ADVERSE REACTIONS

The most common adverse reactions (≥10%) are fatigue, joint swelling or discomfort, edema, hot flush, diarrhea, vomiting, cough, hypertension, dyspnea, urinary tract infection and contusion.

The most common laboratory abnormalities (>20%) are anemia, elevated alkaline phosphatase, hypertriglyceridemia, lymphopenia, hypercholesterolemia, hyperglycemia, elevated AST, hypophosphatemia, elevated ALT and hypokalemia.

Please see additional Important Safety Information throughout.


In patients with mCRPC who did not receive prior cytotoxic chemotherapy:

  • 1088 patients were randomized 1:1 to receive either abiraterone acetate at a dose equivalent to 500 mg of YONSA® once daily (N=546) or placebo once daily (N=542). Both arms were also given a different corticosteroid twice daily. Patients continued treatment until radiographic or clinical (cytotoxic chemotherapy, radiation, or surgical treatment for cancer; pain requiring chronic opioids; or Eastern Cooperative Oncology Group [ECOG] performance status decline to 3 or more) disease progression, unacceptable toxicity, or withdrawal. Patients with moderate or severe pain, opiate use for cancer pain, or visceral organ metastases were excluded
