METHODS We convened an international expert committee of diverse working groups, the Prostate Cancer Working Group 4 (PCWG4), between 2016 and 2025. Our objective was to formulate updated criteria based on emerging evidence and clinical trial data in a biomarker context to provide guidance for clinical trial design, eligibility, and end point assessments for patients with advanced prostate cancer. RESULTS PCWG4 redefines terminology around the disease state and previous therapies in a patient-centric context and terminology focused on androgen pathway modulation. We consider imaging, with a particular focus on positron emission tomography (PET)–defined disease. New recommendations are provided for disease state terminology, defining eligibility criteria, response and delay/prevent end points, intervals for reassessments including imaging, and patient-reported outcome determination. We provide recommendations in a biomarker-based context of use for the intended indication, reflective of patient benefit for specific interventions. We emphasize the need for development of validated PET imaging and molecular and phenotypic criteria as well as trial designs to appropriately risk stratify patients, predict and assess benefit, and measure post-treatment outcomes reliably in a trial framework. CONCLUSION PCWG4 updates recommendations on patient and tumor characterization, therapy development, and imaging criteria and extends guidance into earlier androgen pathway modulator–naïve/sensitive disease states to reflect an evolving, heterogeneous, and diverse patient population to optimize treatment benefits for all patients. 25:[[["$","script","0",{"type":"application/ld+json","dangerouslySetInnerHTML":{"__html":"{\"@context\":\"https://schema.org\",\"@type\":\"CollectionPage\",\"name\":\"Nubeqa: brand Research & Clinical Takeaways\",\"description\":\"Explore peer-reviewed papers on Nubeqa (brand).

Outcomes included progression-free survival (PFS), overall survival (OS), and severe adverse events (AEs), with a separate systematic review of biomarker-driven trials (AMPLITUDE, CAPItello-281, PSMAddition).","key_result":"No triplet regimen showed a statistically significant OS benefit over ARPI+ADT in all-comers. However, **docetaxel+ARPI+ADT** significantly improved OS in high-volume disease (HR 0.76, 95% CI 0.61–0.95; high certainty). For PFS, docetaxel+ARPI+ADT (HR 0.66, 95% CI 0.43–1.01; moderate certainty) and PARPi+ARPI+ADT (HR 0.55, 95% CI 0.23–1.34; low certainty) showed clinically relevant but non-significant trends vs. ARPI+ADT. In biomarker-selected populations: niraparib+abiraterone improved rPFS in HRR-mutated mHSPC (HR 0.63); capivasertib+abiraterone improved rPFS in PTEN-deficient mHSPC (HR 0.81); Lu-177-PSMA+ARPI+ADT improved rPFS in PSMA-positive mHSPC (HR 0.72); OS data remain immature for all three.","limitations":"- Direct head-to-head comparisons between key triplet regimens were unavailable, requiring reliance on indirect NMA contrasts with interstudy heterogeneity.\n- Combining radiographic and clinical PFS endpoints introduced heterogeneity; earlier trials used conventional imaging vs. more sensitive modalities in recent trials, risking stage migration bias.\n- PARPi-, PSMA-, and AKT-based evidence comes from single trials with immature OS data and small phase II samples, yielding low or very low certainty.","practice_takeaway":"For patients with **high-volume mHSPC**, docetaxel+ARPI+ADT offers a proven OS benefit (HR 0.76; high certainty) and should be preferred. For patients with specific biomarkers (HRR mutation, PTEN loss, or PSMA-positive disease), targeted intensification with PARPi, AKT inhibitor, or radioligand therapy respectively shows rPFS benefit—but OS data are still maturing, so treatment decisions must weigh distinct toxicity profiles against uncertain long-term gains."}},{"doi":"10.1200/jco-25-02834","pmid":"41744290","title":"Trial Design and Objectives for Patients With Prostate Cancer: Recommendations From the Prostate Cancer Working Group 4","journal_title":"Journal of Clinical Oncology","journal_issn":"0732-183X","published_at":"2026-02-26T00:00:00.000Z","url":"https://pmc.ncbi.nlm.nih.gov/articles/PMC13132095/","source_score":61,"is_retracted":false,"is_open_access":true,"raw_metadata":{"ooir":{"day":"2026-05-02","doi":"10.1200/jco-25-02834","days":"14","issn":"0732-183X","rank":"9","field":"Clinical Medicine","score":"61","category":"Oncology","categories":["Oncology"],"_categories":["Oncology"]},"pubmed":{"doi":"10.1200/JCO-25-02834","title":"Trial Design and Objectives for Patients With Prostate Cancer: Recommendations From the Prostate Cancer Working Group 4.","journal":"Journal of clinical oncology : official journal of the American Society of Clinical Oncology","methods":"","results":"PCWG4 redefines terminology around the disease state and previous therapies in a patient-centric context and terminology focused on androgen pathway modulation.

(2) incorporating PSMA-PET as non-investigational for staging but investigational for response assessment; (3) updating the bone progression rule — ≥6 new lesions on a restaging scan no longer require a confirmatory scan (vs. the prior 2+2 rule for all cases); (4) endorsing four near-term candidate response biomarkers: pathologic response, PSA declines/nadir, CTC0, and ctDNA decline; and (5) defining PSA progression in the APM setting as any confirmed rise ≥0.2 ng/mL from baseline/nadir on two measurements ≥21 days apart.","limitations":"This is a consensus guideline document, not a primary clinical trial — recommendations are expert-based and many proposed PSMA-PET criteria (e.g., SUV-based response, PET-defined rPFS) require prospective phase III validation. The document acknowledges that most novel biomarkers (ctDNA, CTC0, PSA declines) are not yet validated surrogates for OS or regulatory approval.","practice_takeaway":"Clinicians designing or interpreting prostate cancer trials should adopt APMN/APMS/APMR terminology and obtain PSMA-PET at baseline where feasible, while tracking CT/bone scan findings independently. For bone progression on bone scintigraphy or PSMA-PET, a confirmatory scan is no longer required when ≥6 new lesions are seen — act on that finding promptly rather than waiting."}}],"initialOffset":5,"fetchConfig":{"kind":"tags","tags":[{"tag_type":"brand","value":"Nubeqa"}]},"breadcrumbItems":[{"name":"Home","href":"/"},{"name":"Research Hub","href":"/hub"},{"name":"Brands","href":"/hub/tag/brand"},{"name":"Nubeqa"}],"hrefConfig":{"basePath":"/hub/papers","webViewQueryParams":{"hub_ctx":"tag","hub_tag_type":"brand","hub_tag_value":"Nubeqa"}}}]]
