Delving into the Latest Updates on Estramustine Phosphate Sodium with Synapse

This study is for men who have prostate cancer and have failed local therapy or are not a candidate for prostatectomy or radiation therapy. The purpose of this research study is to assess the safety and benefit of androgen deprivation therapy (ADT, blocks hormones) plus chemotherapy. Degarelix is the hormone blocking drug that will be used. Doxorubicin, Ketoconazole, Docetaxel and Estramustine are the chemotherapy drugs that will be used. The drugs used in this study are approved by the Food and Drug Administration (FDA).
Participants will be treated with ADT plus chemotherapy for three, four, or five 8-week cycles (12, 18, or 24 months). The number of cycles of chemotherapy they receive and the number of months they receive ADT will be based on their disease. The current standard treatment is ADT and chemotherapy. What differs in this research study is the cycling and combination of chemotherapy drugs chosen. The drugs chosen for this study have fewer side effects and are believed to provide maximum benefit.

Neoadjuvant Androgen Deprivation Therapy and Chemotherapy Followed by Radical Prostatectomy in Patients With Prostate Cancer

This is a study for men who have locally-advanced prostate cancer and are eligible to undergo prostatectomy. Standard treatment is prostatectomy alone, but there is a chance that cancer may spread to other organs in the future, even after the prostate is removed. If this were to occur, standard treatment would be androgen deprivation therapy (ADT; hormone therapy that blocks testosterone) plus chemotherapy. Clinical trials suggest that neoadjuvant treatment (treatment given before primary therapy) may prevent a recurrence. The purpose of this research study is to assess the safety and benefit of ADT plus chemotherapy given before prostate removal.

INTRODUCTION:

Serum prostate specific antigen (PSA) is a well-known prognostic parameter in men with prostate cancer. The treatment of men with very high PSA values and apparently no detectable metastases is not fully established.

PATIENTS AND METHODS:

Ancillary analysis from the GETUG 12 phase 3 trial. Patients with non-metastatic high-risk prostate cancer by bone and computerized tomography (CT) scan were randomly assigned to receive androgen deprivation therapy (ADT) and docetaxel plus estramustine or ADT alone. Relapse-free survival (RFS), clinical RFS, metastases-free survival (MFS), overall survival (OS), and prostate cancer-specific survival (PCSS) were estimated using the Kaplan-Meier method for different levels of PSA (50 ng/mL, 75 ng/mL, and 100 ng/mL). The relationship between PSA and outcomes was studied using residual-based approaches and spline functions.

RESULTS:

The median follow-up was 12 years (range: 0-15.3). Baseline PSA (<50 ng/mL, n = 328; ≥50ng/mL, n = 85) was associated with improved RFS (P = .0005), cRFS (P = .0024), and MFS (P = .0068). The 12-year RFS rate was 46.33% (CI 40.59-51.86), 33.59% (CI 22.55-44.97), and 11.76% (1.96-31.20) in men with PSA values <50 ng/mL (n = 328), 50-100 ng/mL (n = 68), and ≥100 ng/mL (n = 17), respectively. Exploratory analyses revealed no deviation from the linear relationship assumption between PSA and the log hazard of events.

CONCLUSIONS:

Men with apparently localized prostate cancer and a high baseline PSA value have a reasonable chance of being long-term disease-free when treated with curative intent combining systemic and local therapy.

Activity and safety of KEES - an oral multi-drug chemo-hormonal metronomic combination regimen in metastatic castration-resistant prostate cancer.

Article

Author: Papantoniou, Dimitrios ; Ekholm, Maria ; Asowed, Mustafa ; Elander, Nils O ; Pettersson, Linn

BACKGROUND:

Metastatic castration-resistant prostate cancer (mCRPC) remains a therapeutic challenge and evidence for late-line treatments in real-life is limited. The present study investigates the efficacy and safety of an oral metronomic chemo-hormonal regimen including cyclophosphamide, etoposide, estramustine, ketoconazole and prednisolone (KEES) administered in a consecutive biweekly schedule.

METHODS:

A retrospective cohort study in two Swedish regions was conducted. Overall (OS) and progression-free survival (PFS), biochemical response rate (bRR) and toxicities were analyzed.

RESULTS:

One hundred and twenty-three patients treated with KEES after initial treatment with at least a taxane or an androgen-receptor targeting agents (ARTA) were identified. Of those, 95 (77%) had received both agents and were the primary analysis population. Median (95% CI) OS and PFS in the pre-treated population were 12.3 (10.1-15.0) and 4.4 (3.8-5.5) months, respectively. Biochemical response, defined as ≥ 50% prostate-specific antigen (PSA) reduction, occurred in 26 patients (29%), and any PSA reduction in 59 (65%). PFS was independent of prior treatments used, and KEES seemed to be effective in late treatment lines. The bRR was higher compared to historical data of metronomic treatments in docetaxel and ARTA pre-treated populations. In multivariable analyses, performance status (PS) ≥ 2 and increasing alkaline phosphatase (ALP) predicted for worse OS. Nausea, fatigue, thromboembolic events and bone marrow suppression were the predominant toxicities.

CONCLUSIONS:

KEES demonstrated meaningful efficacy in heavily pre-treated CRPC patients, especially those with PS 0-1 and lower baseline ALP, and had an acceptable toxicity profile.
