Brief Summary

Prostate cancer has the second highest incidence rate and is the fifth leading cause of cancer-related deaths among men worldwide. The purpose of this study is to assess safety, pharmacokinetics, and efficacy of ABBV-969 as a monotherapy. ABBV-969 is an investigational drug being developed for the treatment of metastatic castration-resistant prostate cancer (mCRPC). There are parts to this study. Participants will receive ABBV-969 as a single agent at different doses. Approximately 230 adult participants will be enrolled in the study across sites worldwide. In part 1 (dose escalation), ABBV-969 will be intravenously infused in escalating doses as a monotherapy. In part 2, multiple doses will be selected from Part 1 and mCRPC participants will be assigned to one of these doses in a randomized fashion to determine the recommended Phase 2 dose. The estimated duration of the study is up to 3 years. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic and may require frequent medical assessments, blood tests, and scans.

Outcome Measures

Primary Outcomes (2)

  • Percentage of Participants With Adverse Events (AEs)

    An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study. A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above.

    Up to 3 Years

  • Percentage of Participants Achieving Prostate Specific Antigen (PSA) response

    PSA response is defined as \>= 50% PSA decrease from baseline.

    Up to 3 Years

Secondary Outcomes (7)

  • Maximum Observed Plasma Concentration (Cmax) of ABBV-969

    Up to 3 Years

  • Time to Maximum Observed Concentration (Tmax) of ABBV-969

    Up to 3 Years

  • Terminal Phase Elimination Half-Life (t1/2) of ABBV-969

    Up to 3 Years

  • Area Under the Plasma/Serum Concentration Versus Time Curve (AUC) of ABBV-969

    Up to 3 Years

  • Antidrug Antibody (ADA)

    Up to 3 Years

  • +2 more secondary outcomes

Eligibility Criteria

Age18 Years+
Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Histological, pathological, and/or cytological confirmation of adenocarcinoma of the prostate.
  • Estimated life expectancy \> 6 months.
  • An Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
  • Must have progressed on prior novel hormonal agents (NHAs) (e.g., abiraterone acetate and/or enzalutamide) for the treatment of metastatic prostate cancer and/or castration-resistant prostate cancer (CRPC). Determination of progression is done per local investigator according to Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1 and/or Prostate Cancer Working Group 3 (PCWG3).
  • Serum testosterone levels \<= 50 ng/dL (\<= 1.73 nmol/L) within the screening period and prior to the first dose of the study drug.
  • Must have received at least one NHA (e.g., enzalutamide and/or abiraterone). Additionally, participants must have received at least one taxane for prostate cancer (or are intolerant to, or unable to get access to taxanes).
  • Must have \>= 1 metastatic lesion that is present on baseline computed tomography (CT), magnetic resonance imaging (MRI), or bone scan imaging obtained \<= 28 days prior to beginning study therapy.
  • Serum prostate specific antigen (PSA) level \>= 1.0 ng/mL.
  • Availability of representative baseline tumor tissue (most recent archived tumor tissue after any novel hormonal agent (NHA) and/or any Prostate-Specific Membrane Antigen (PSMA) targeted therapy or fresh biopsy collected during screening if collecting a fresh biopsy at screening is deemed safe in the judgment of the investigator) suitable for immunohistochemistry (IHC) testing.
  • Laboratory values meeting the criteria laid out in the protocol.
  • QT interval corrected for heart rate (QTc) \<= 470 msec (using Fridericia's correction), no \>= Grade 3 arrythmia, and no other clinically significant cardiac abnormalities.

You may not qualify if:

  • Unresolved Grade 2 or higher toxicities related to previous anticancer therapy except alopecia.
  • History of other active malignancy, as laid out in the protocol.
  • History of interstitial lung disease (ILD) or pneumonitis that required treatment with systemic steroids, nor any evidence of active ILD or pneumonitis on screening chest CT scan.
  • History of or active idiopathic pulmonary fibrosis, organizing pneumonia (e.g., bronchiolitis obliterans), drug-induced pneumonitis, or idiopathic pneumonitis.
  • History of or active clinically significant, intercurrent lung-specific illnesses including, but not limited to those listed in the protocol.
