A Phase I/IIa Theranostic Study of 64Cu-SAR-bisPSMA and 67Cu-SAR-bisPSMA for Identification and Treatment of PSMA-expressing Metastatic Castrate Resistant Prostate Cancer

Active drug

Investigational drug(s) in this trial have shown anticancer activity in clinical trials

High burden on patient

The trial has a high burden on patients. An example would be a phase 1 trial with extra tumor biopsies and frequent pharmacokinetic blood draws.

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

HealthScout AI summary: Adults with PSMA-positive metastatic castration-resistant prostate cancer after at least one second-generation AR pathway inhibitor (chemotherapy excluded in expansion) undergo 64Cu‑SAR‑bisPSMA PET/CT for selection/dosimetry followed by up to four cycles of 67Cu‑SAR‑bisPSMA, a bivalent PSMA‑targeted beta‑emitting radiotherapeutic; an expansion cohort allows concomitant enzalutamide. Excludes brain mets, small cell/neuroendocrine histology, significant comorbidities, and PSMA‑negative progressing lesions (except in early phases).

ClinicalTrials.gov ID: NCT04868604

TRAMP: Tumor Necrosis Factor- α Blockade and AR Inhibition in Men With CRPC

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

HealthScout AI summary: Single-arm study for men with metastatic or non-metastatic CRPC after at least one novel hormonal therapy (± one prior taxane), ECOG 0–2, evaluating apalutamide combined with golimumab, a TNF‑α–neutralizing monoclonal antibody intended to modulate inflammation-driven resistance. Excludes small cell/neuroendocrine histology and patients with active/latent TB, significant infections, hepatitis B/C, HIV, seizure risk, or prior TNF‑α inhibitor use.

High burden on patient

The trial has a high burden on patients. An example would be a phase 1 trial with extra tumor biopsies and frequent pharmacokinetic blood draws.

Started >3 years ago
