Mechanism & Pharmacology

Simplified explanation

Casodex, known generically as bicalutamide, acts as an anti-androgen. But what does that mean?

In simple terms, it blocks the effects of male hormones, primarily testosterone, on prostate cells. This is crucial since prostate cancer cells often rely on testosterone to grow and thrive.

By inhibiting these hormones, Casodex helps slow the progression of the cancer or even shrink existing tumours. It's primarily used in combination with other treatments, like hormone therapy, to provide a more comprehensive approach to managing prostate cancer.

Clinical terms

Understanding the clinical terminology associated with bicalutamide enhances comprehension of its therapeutic use:

• Anti-androgen: A substance that blocks the action of androgens (male hormones).
• Hormonal therapy: Treatment that alters hormone production or action to manage diseases such as cancer.
• Prostate cancer: A common cancer in men that occurs in the prostate, a small walnut-sized gland that produces seminal fluid.
• Metastatic: Referring to cancer that has spread from its original site to other parts of the body.

Indications & Off-Label Uses

Approved indications by TGA

According to the Therapeutic Goods Administration (TGA) of Australia, Casodex is approved for treating:

• Metastatic prostate cancer: Typically used in combination with LHRH analogues.
• Locally advanced prostate cancer: Used as monotherapy in certain non-metastatic cases.

These approved indications highlight its crucial role in prostate cancer management, especially in advanced stages where hormone dependency is significant.

Off-label uses in Australian clinical practice

While primarily indicated for prostate cancer, Casodex may also be used off-label in Australian clinical practice. For instance:

• Adjuvant therapy: Following surgery to reduce recurrence risk.
• Advanced breast cancer: In cases where other hormonal treatments are unsuitable.

These off-label applications should be approached with caution and assessed on a case-by-case basis, considering potential benefits versus risks.

Key Clinical Findings

Recent studies examining the efficacy and safety of bicalutamide have surfaced between 2022 and 2025, focusing on post-treatment outcomes:

• One notable Australian study evaluated the long-term effects of Casodex when used in combination therapies. It highlighted improved survival rates in patients with metastatic prostate cancer.
• Internationally, a large clinical trial emphasised safety, finding that most side effects were manageable and minor.
• Overall, these studies reaffirmed Casodex's vital role in prostate cancer treatment, demonstrating both its effectiveness and relative safety.
