Brief Summary:

This research study is examining whether Neratinib has any activity in participants with prostate cancer that has spread and is no longer responding to hormonal treatment.

- The names of the study drug involved in this study is neratinib.


Condition or disease Intervention/treatment Phase
Metastatic Prostate Adenocarcinoma Castration-resistant Prostate Cancer Prostate Cancer Prostate Cancer Metastatic Drug: Neratinib Phase 2

Detailed Description:

In this research study, investigators are testing neratinib in prostate cancer that has spread and is no longer responding to hormonal therapies. This research study involves testing tumors for evidence of increased HER2 signaling, and treating those who do have increased HER2 signaling with a targeted therapy.

The research study procedures include: screening for eligibility and study treatment including evaluations and follow up visits.

- The names of the study drug involved in this study is neratinib. It is expected that about 14 people will take part in this research study.

This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific disease.

"Investigational" means that the drug is being studied. The U.S. Food and Drug Administration (FDA) has not approved neratinib for this specific disease but it has been approved for other uses.

Other Name: Nerlynx




Primary Outcome Measures :
  1. Response Rate to Neratinib [ Time Frame: 84 days ]
    defined by PSA response and/or radiographic response after three 28-day cycles of treatment.


Secondary Outcome Measures :
  1. Best PSA response [ Time Frame: 24 Months ]
    the best percent change in PSA from baseline while on neratinib among PSA evaluable patients will be visualized for each individual patient using waterfall plot

  2. Best Radiographic Response [ Time Frame: Baseline, Every 3 Cycles through study completion, up to 24 months. ]
    the maximum change of tumor area from baseline while on neratinib among target disease evaluable patients will be visualized for each individual patient using waterfall plot.

  3. Duration of Response [ Time Frame: Baseline, Every 3 Cycles through study completion, up to 24 months. ]
    patients who met either duration of biochemical response or duration of radiographic response until biochemical or radiographic response criteria are met, will be presented using Kaplan-Meier method.

  4. Progression Free Survival [ Time Frame: 24 Months ]

    Progression-Free Survival (PFS) is defined as the time from registration to the earlier of progression by PCWG3 criteria or death due to any cause.

    PCWG3 progression is defined as when the treating physician feels the patient is "no longer clinically benefitting" (NLCB) from therapy. Generally, this is understood as radiographic or clinical/symptomatic progression (i.e. not PSA progression alone), but PCWG3 criteria allow treatment beyond radiographic progression when the treating physician feels that the patient is continuing to derive clinical benefit from therapy (compared to other available treatments or no treatment). Participants alive without disease progression are censored at date of last disease evaluation


  5. Overall Survival [ Time Frame: 6 Months ]
    Overall Survival (OS) is defined as the time from registration to death due to any cause or censored at date last known alive

  6. Number of Participants with Treatment Related Adverse Events as Assessed by CTCAE v5.0 [ Time Frame: Baseline, through study (up to 24 Months, and until the end of the 30-day post-treatment follow-up. ]
    For toxicity reporting, all adverse events will be reported using CTCAE version 5.0

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Histologically or cytologically confirmed metastatic prostate adenocarcinoma (secondary components of variant histology are acceptable).
  • Castration-resistance, with progression on medical/surgical castration and confirmed baseline testosterone <50ng/dL
  • Ongoing castration, either with prior orchiectomy or ongoing gonadotropin releasing hormone (GnRH) agonist/antagonist therapy as per investigator discretion
  • Anti-resorptive therapy (e.g. denosumab, bisphosphonates) is allowable at any point
  • Prior progression on (or intolerance of) at least one androgen-receptor signaling inhibitor(i.e. abiraterone, enzalutamide, apalutamide, darolutamide). Progression is per investigator and can include prostate specific antigen (PSA), symptomatic, and/or radiographic progression. There is no limit to prior therapies, nor any requirement on taxane treatments.
  • Positive biomarker (phospho human epidermal growth factor receptor 2, pHER2) assessment on baseline tissue. Archival tissue is acceptable but must have been acquired during or after prior abiraterone and/or enzalutamide therapy and must meet tissue specifications outlined in the biomarker assessment section of the protocol. If suitable archival tissue is not available, then the patient must be willing to undergo a research biopsy to obtain tissue for biomarker assessment.
  • Evaluable for response, defined as at least one of the following:

    • Baseline PSA >=2.0 ng/mL
    • Measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1
  • Ability to understand and willingness to sign informed consent.
  • Willingness to undergo research biopsy on study, as well as at baseline if needed to obtain tissue for biomarker assessment.
  • Age >=18 years
  • Eastern Cooperative Oncology Group (ECOG) performance status ≤2
  • Adequate organ and marrow function as defined below:

    • leukocytes ≥2,000/mcL
    • absolute neutrophil count ≥1,500/mcL
    • platelets ≥100,000/mcL
    • total bilirubin ≤ 1.5 x institutional upper limit of normal (ULN), unless participant has known or suspected Gilbert's syndrome
    • AST(SGOT)/ALT(SGPT) ≤2.5 × institutional ULN or <=5 x ULN if liver metastases present
    • Estimated glomerular filtration rate (eGFR) ≥ 30 mL/min
  • Male participants must agree to use contraception with any female partners who are of reproductive potential prior to the study entry, for the duration of the study participation, and 6 months after completion of administration.
  • Human immunodeficiency virus (HIV)-infected participants on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial.
  • For participants with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated.
  • Participants with a history of hepatitis C virus (HCV) infection must have been treated and cured. For participants with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load.
  • Participants with brain metastases are eligible if (1) brain metastases are asymptomatic and patients are on a stable dose of corticosteroids (if needed) for 14 days prior to enrollment, or (2) brain metastases have been treated with local therapy and follow-up brain imaging shows no evidence of progression.
  • Participants with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial.
  • Participants must be able to swallow pills.

Exclusion Criteria:

  • Use of a strong CYP3A4/CYP2C8 inducer/inhibitor within 3 half-lives prior to first dose of study treatment
  • Participants who are receiving any other investigational agents
  • History of allergic reaction to HER2 inhibitors
  • Child-Pugh class C hepatic impairment
  • Current use of a proton pump inhibitor (no specific wash-out period)
  • Corrected QTc interval >450 msec with institutional standard correction formula. One EKG is sufficient. In the case of potentially reversible causes of QT prolongation (e.g. medications, electrolyte abnormalities), EKG may be repeated once during screening and that result may be used to determine eligibility.
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
  • Uncontrolled baseline diarrhea or uncontrolled predisposition to intermittent diarrhea, e.g. uncontrolled inflammatory bowel diseases.
