RISK-ADAPT Protocol in Metastatic Hormone-Sensitive Prostate Cancer (mHSPC)

Официальное название

A Pragmatic Phase 2 Trial of Risk-Adapted Treatment Approaches Including Treatment De-escalation to Minimize Adverse Effects of Hormonal Therapy in Metastatic Hormone-Sensitive Prostate Cancer.

Обзор

This is a prospective, interventional, non-randomized, phase 2 study to assess oncologic outcomes of metastatic hormone-sensitive prostate cancer (mCSPC) patients who receive a risk-adapted treatment approach followed by treatment de-escalation at the Medstar Health network. A pragmatic design will be implemented in order to make the study available to patients at greatest needs from minority populations in the community. Additional assessments include quality-of-life (QoL) and sexual function changes as well as correlative studies. A maximum of 108 patients will be enrolled in this study. The investigators hypothesize that with a risk-adapted treatment approach followed by treatment de-escalation, more than 50% of patients will have radiographic progression-free survival (rPFS) at 36 months. Additionally, the investigators hypothesize that the risk-stratified de-escalation approach will result in fewer treatment-related adverse events and better QoL, compared to historical controls.

Вмешательства

• Препарат Androgen Deprivation Therapy (ADT)
  ADT, Gonadotropin-releasing hormone (GnRH) agonist or antagonists, as prescribed by the treating physician.
• Препарат Androgen Receptor Pathway Inhibitor (ARPI)
  Darolutamide is the preferred ARPI for this study; however, patients may receive abiraterone, apalutamide, or enzalutamide at the discretion of their oncologist and based on patient preference.
• Лучевая терапия Prostate Radiation
  prostate radiation, with or without radiation to metastatic sites
• Препарат Docetaxel
  Docetaxel will be administered as prescribed by the treating physician.

Критерии участия

Критерии включения

• Adult patients with metastatic castrate sensitive prostate cancer that are eligible for standard of care (SOC) per treating physician.

a. Low risk SOC: ADT + ARPI + radiation to the prostate i. For patients with low-risk disease (defined in Section 8.1), prior treatment with ADT or ARPI for up to 8 weeks for mCSPC is permitted; however, prior treatment with docetaxel is not allowed.

b. High risk SOC: ADT + ARPI +/- docetaxel i. For patients with high-risk disease (defined in Section 8.1), prior treatment with ADT, ARPI, or docetaxel for up to 8 weeks for mCSPC is permitted.

• Patients who can give informed consent and are willing to comply with follow-up visits and treatment plans.

Критерии исключения

• Patients for whom, in the opinion of the investigator, participation in the study, use of the drugs outlined in the study, or use of the risk-adapted treatment de-escalation strategy is not appropriate or safe.
• Patients who have received prior treatment with any of the following:

• Chemotherapy other than docetaxel for prostate cancer any time prior to enrollment;
• Radiopharmaceuticals for prostate cancer any time prior to enrollment.
• Patients who have received treatment with radiotherapy (EBRT, brachytherapy, or radiopharmaceuticals) within 2 weeks before prior to the start of study treatment.
• Patients with prior treatment with an ARPI for non-metastatic disease within 6 months of diagnosis of metastatic disease are not eligible.

a. Note: Patients who were diagnosed with metastatic disease or more than 6 months after treatment with an ARPI non-metastatic disease are eligible.

• Patients who had previous (within 28 days before the start of study drug or 4 half-lives of the investigational treatment of the previous study, whichever is longer) or concomitant participation in another clinical study with investigational medicinal product(s).
• Patients with an inability to swallow oral medications in the opinion of the clinical investigator.
• Patients with leptomeningeal disease.
