Berlin, Germany – october 19, 2025 – A groundbreaking study presented at the 2025 European Society for Medical Oncology (ESMO) Congress indicates that adding Apalutamide to standard Androgen Deprivation Therapy (ADT) significantly reduces the risk of metastasis and castration-resistant disease in men with biochemically recurrent prostate cancer. The Phase 3 PRESTO trial demonstrated substantial improvements in several key metrics, offering renewed hope for patients facing this challenging condition.
Key Findings from the PRESTO Trial
Researchers found that the combination of ADT plus Apalutamide led to improved metastasis-free survival, extended the time before the development of castration-resistant prostate cancer, and enhanced prostate-specific antigen progression-free survival, especially in patients who regained testosterone levels. These findings suggest a powerful synergistic effect when Apalutamide is integrated into existing treatment protocols.
“Combined androgen blockade with ADT plus Apalutamide appears to improve clinically relevant long-term end points,” stated Rahul Aggarwal, MD, of the University of California, San Francisco, during the presentation of the data. “While the study wasn’t designed to directly compare all arms, the addition of abiraterone with prednisone did not show further advantages and was linked to increased side effects.”
Understanding the PRESTO study Design
The PRESTO trial involved 503 patients with biochemically recurrent prostate cancer, characterized by a short Prostate-Specific antigen (PSA) doubling time, indicating a higher risk of progression. Participants were randomly assigned to one of three treatment groups: LHRH analog alone, LHRH analog plus Apalutamide, or LHRH analog, Apalutamide, abiraterone, and prednisone.The treatment duration was 12 months for all groups.
Patients enrolled in the trial had previously undergone radical prostatectomy and displayed a PSA level exceeding 0.5 ng/mL,along with a PSA doubling time of nine months or less. Most participants had also previously received either adjuvant or salvage radiation therapy.
Treatment Outcomes: A Closer Look
initial results from the study had already established that ADT plus Apalutamide was a viable treatment option for high-risk biochemically recurrent prostate cancer. the latest analysis,with a median follow-up of 61.0 months, further solidifies these findings and provides a more comprehensive understanding of long-term benefits. The addition of both Apalutamide and abiraterone did not negatively impact the patients’ health-related quality of life.
| Endpoint | ADT alone | ADT + Apalutamide | ADT + Apalutamide + Abiraterone |
|---|---|---|---|
| Metastasis-free Survival (HR) | 1.00 | 0.80 (0.56-1.13) | 0.92 (0.56-1.13) |
| Time to CRPC (HR) | 1.00 | 0.58 (0.36-0.95) | 0.55 (0.34-0.90) |
| PSA-PFS (HR) | 1.00 | 0.72 (0.55-0.93) | 0.67 (0.50-0.90) |
Note: HR = Hazard Ratio. Lower HR values indicate a reduced risk.
Safety Considerations
While generally well-tolerated, the apalutamide combination did result in a slightly higher incidence of grade 2 or higher skin rash and an increased risk of falls compared to ADT alone. However, the addition of abiraterone and prednisone was associated with a marked increase in grade 3 or higher hypertension.

Prostate Cancer: A Growing Concern
Prostate cancer remains a significant health challenge worldwide. Advances in treatment are continuously being made, but early detection remains key. understanding risk factors, such as age, family history, and race, and engaging in proactive health management are essential steps in combating this disease. Ongoing research continues to refine treatment approaches and improve patient outcomes.
Frequently Asked Questions About Prostate Cancer Treatment
- What is androgen deprivation therapy (ADT)? ADT reduces androgen levels in the body, which can slow the growth of prostate cancer cells.
- What is Apalutamide and how does it work? Apalutamide is a medication that blocks the effects of androgens, further hindering cancer cell growth.
- What does the PRESTO trial tell us about prostate cancer treatment? The trial suggests that combining Apalutamide with ADT can significantly delay the progression of recurrent prostate cancer.
- Are there side effects associated with these treatments? ADT and apalutamide can cause side effects, including fatigue, hot flashes, and sexual dysfunction.
- Is abiraterone a beneficial addition to Apalutamide and ADT? The PRESTO trial indicated that adding abiraterone didn’t offer additional benefits and increased toxicity.
- How crucial is early detection in prostate cancer? early detection through regular screenings significantly improves treatment outcomes and increases the chances of successful recovery.
- What is castration-resistant prostate cancer (CRPC)? CRPC occurs when prostate cancer cells continue to grow even after androgen levels have been reduced through ADT.

Apalutamide Enhances Long-term Survival in Biochemically Recurrent Prostate Cancer When Combined with Androgen deprivation Therapy
Understanding Biochemically Recurrent Prostate Cancer
Biochemical recurrence (BCR) of prostate cancer, frequently enough detected by a rising Prostate-Specific antigen (PSA) level after initial treatment (surgery or radiation), doesn’t necessarily mean the cancer has visibly spread. Though, it does indicate that cancer cells remain in the body. Managing BCR is crucial to prevent metastasis – the spread of cancer to other parts of the body – and ultimately improve long-term survival. Conventional management often involves androgen deprivation therapy (ADT), but its effectiveness can wane over time. This is where apalutamide enters the picture.
The Role of Androgen Deprivation Therapy (ADT)
Androgen deprivation therapy (ADT) works by lowering the levels of androgens (like testosterone) in the body. prostate cancer cells rely on these hormones to grow. ADT can include:
* Surgical castration: Removal of the testicles.
* LHRH agonists/antagonists: Medications that stop the testicles from producing testosterone.
* Anti-androgens: Medications that block androgens from reaching cancer cells.
While initially effective, many patients develop resistance to ADT, leading to disease progression. This resistance is a notable challenge in prostate cancer management.ADT side effects – including fatigue, sexual dysfunction, and bone loss – also impact quality of life.
Apalutamide: A Next-Generation Androgen Receptor Inhibitor
Apalutamide (Erleada) is a second-generation nonsteroidal antiandrogen. Unlike older anti-androgens, apalutamide exhibits a higher affinity for the androgen receptor (AR) and more completely blocks androgen binding. This means it’s more potent at stopping cancer cell growth driven by androgens.
Here’s how apalutamide works:
- blocks Androgen Binding: Apalutamide binds to the androgen receptor,preventing testosterone and other androgens from attaching.
- Inhibits AR translocation: It prevents the AR from moving into the nucleus of cancer cells, where it normally activates genes that promote growth.
- Reduces AR Variants: Apalutamide can also reduce the levels of AR variants, which can contribute to ADT resistance.
the ENZAMET and SPARTAN Trials: Key Evidence
the efficacy of apalutamide in combination with ADT for BCR has been demonstrated in two pivotal clinical trials: ENZAMET and SPARTAN.
* ENZAMET (NCT02672954): This Phase III trial involved men with metastatic hormone-sensitive prostate cancer (mHSPC) initiating ADT.adding apalutamide significantly improved overall survival (OS) and radiographic progression-free survival (rPFS).
* SPARTAN (NCT02948734): This Phase III trial focused on men with non-metastatic castration-resistant prostate cancer (nmCRPC) who had previously been treated with ADT. Apalutamide significantly extended metastasis-free survival (MFS).
Both trials consistently showed that adding apalutamide to ADT delayed disease progression and, crucially, improved long-term survival outcomes.
Benefits of combining Apalutamide with ADT
The combination of apalutamide and ADT offers several potential benefits for men with BCR:
* Extended Survival: Clinical trials demonstrate a statistically significant betterment in overall survival.
* delayed Metastasis: Apalutamide can delay the spread of cancer to other parts of the body.
* Increased Time to Chemotherapy: By slowing disease progression, the need for more aggressive treatments like chemotherapy may be delayed.
* Improved Quality of Life: While ADT side effects persist,delaying disease progression can help maintain a better quality of life for longer.
managing Side Effects of Apalutamide
like all medications, apalutamide can cause side effects. Common side effects include:
* Fatigue
* Hypertension (high blood pressure)
* Falls
* Fractures
* Cardiovascular events (rare, but important to monitor)
regular monitoring by a healthcare professional is essential to manage these side effects. Lifestyle modifications, such as exercise and a healthy diet, can also help mitigate some of the adverse effects. Open interaction with your doctor about any side effects you experience is crucial.
Patient Selection and Treatment Considerations
Not all men with BCR are suitable candidates for apalutamide.Factors considered when determining eligibility include:
* PSA Level: The level of PSA at the time of recurrence.
* Time to BCR: The length of time between initial treatment and recurrence.
* Gleason Score: A measure of the aggressiveness of the cancer.
* Overall Health: The patient’s general health and ability to tolerate treatment.
Treatment duration with apalutamide is typically continued until disease progression or unacceptable toxicity.
