Study Comparing Ifinatamab Deruxtecan and Docetaxel for Patients with Advanced Prostate Cancer Resistant to Hormone Therapy
This trial, conducted across multiple countries including Germany, Denmark, Czechia, Sweden, and Austria, compares a new treatment called ifinatamib deruxtecan with docetaxel chemotherapy for men with metastatic castration-resistant prostate cancer.
Main inclusion criteria: Participants must be male, at least 18 years old, with confirmed prostate cancer (adenocarcinoma type without small cell features) that has spread to other parts of the body. The cancer must show progression while on hormone therapy or after surgical removal of testicles. Participants must have received treatment with 1 or 2 androgen receptor pathway inhibitors for at least 8 weeks, with the cancer continuing to progress. They need good physical function (ECOG score 0-1) and must provide tumor tissue samples.
Main exclusion criteria: Patients with other serious health conditions, those currently receiving other experimental treatments, patients with known allergies to the study drugs, uncontrolled heart conditions, severe liver or kidney problems, active infections, untreated brain metastases, other active cancers within the past 5 years, or those unable to take oral medications are excluded.
Trial focus and goals: The study evaluates whether ifinatamib deruxtecan can help patients live longer and slow cancer progression as seen on imaging scans. Researchers will monitor how long patients live, how long before their cancer worsens, response rates, and any side effects. The trial continues until disease progression, unacceptable side effects, or participant withdrawal.
Investigational drugs: Ifinatamib deruxtecan is an antibody-drug conjugate that targets specific proteins on cancer cells to deliver cancer-fighting drugs directly to them. Docetaxel is a well-established chemotherapy drug that damages cancer cell DNA to prevent growth and division.
Study of Darolutamide and Testosterone for Patients with Advanced Prostate Cancer Resistant to Standard Hormone Therapy
This German trial examines a novel approach combining darolutamide (which blocks male hormones) with bipolar androgen therapy (which alternates between high and low testosterone levels) for men with metastatic castration-resistant prostate cancer.
Main inclusion criteria: Participants must be male, at least 18 years old, with confirmed prostate cancer that has spread and continues to grow despite hormone-lowering treatments. They must have a PSA level of 1.0 ng/mL or higher and be receiving continuous hormone therapy with testosterone levels below 50 ng/dL. The cancer must have progressed while on specific medications (Apalutamide, Darolutamide, or Enzalutamide), shown by either rising PSA levels or tumor growth on scans. Participants need adequate kidney, liver, and blood cell function, and good physical status (ECOG 0-2).
Main exclusion criteria: Patients with allergies to study drugs, serious heart problems (including recent heart attack, unstable chest pain, or heart failure), history of seizures, severe liver or kidney problems, those taking certain interacting medications, recent chemotherapy recipients, those with other serious medical conditions, or those unable to follow study procedures are excluded.
Trial focus and goals: The study tests whether combining darolutamide with bipolar androgen therapy can improve progression-free survival and quality of life compared to standard care. Treatment continues until disease progression, significant side effects, or the study ends in December 2027. Researchers will monitor PSA levels, perform imaging scans, track side effects, and assess quality of life using standardized questionnaires.
Investigational drugs: Darolutamide blocks male hormone effects that stimulate cancer growth. Bipolar Androgen Therapy involves alternating between high testosterone doses (given as gel applied to skin) and low levels, which can disrupt cancer cell growth patterns. Both are combined with ongoing androgen deprivation therapy.
Study of ifinatamab deruxtecan alone or in combination with other treatments for patients with metastatic castration-resistant prostate cancer
This trial across seven European countries (Poland, France, Ireland, Spain, Netherlands, Italy, Germany) tests ifinatamib deruxtecan, either alone or combined with other medications, for men with metastatic castration-resistant prostate cancer whose disease has progressed despite hormone therapy.
Main inclusion criteria: Participants must be male, at least 18 years old, with confirmed prostate cancer (adenocarcinoma without small cell features) that has spread to other body parts. The cancer must show progression while on hormone therapy within 6 months before screening. Participants must have received and shown progression during or after treatment with 1 or 2 androgen receptor pathway inhibitors. They need good physical function (ECOG 0-1), adequate bone marrow, liver, and kidney function. If receiving bone treatments, doses must be stable for at least 4 weeks. Prior treatment with PARP inhibitors (if recommended) or being unsuitable for such treatment is required.
Main exclusion criteria: Patients younger than 18, those without metastatic castration-resistant prostate cancer, female patients, those unable to provide informed consent, patients with severe autoimmune disease, active infections (including HIV, hepatitis B or C), untreated brain metastases, other active cancers within 5 years, pregnant or breastfeeding women, those with severe organ dysfunction, psychiatric conditions affecting study compliance, or those who received previous immunotherapy with serious side effects are excluded.
Trial focus and goals: The study evaluates safety, effectiveness, and how long patients live without cancer progression. Monitoring includes PSA level measurements, imaging scans, and assessments of response to treatment and quality of life. Treatment continues until progression, unacceptable side effects, or participant withdrawal, with the study expected to continue until December 2029.
Investigational drugs: Ifinatamib deruxtecan is an antibody-drug conjugate administered through intravenous infusion that targets specific proteins on cancer cells to deliver cancer-fighting drugs directly to tumors.
Study of PF-06821497 and Enzalutamide for Men with Advanced Prostate Cancer Resistant to Hormone Therapy
This large trial across 14 European countries tests whether adding the experimental drug PF-06821497 (Mevrometostat) to enzalutamide can improve outcomes for men with metastatic castration-resistant prostate cancer.
Main inclusion criteria: Participants must be male, at least 18 years old, with confirmed prostate cancer (adenocarcinoma without small cell features) that has spread to bones or soft tissues and continues to grow despite low testosterone levels (50 ng/dL or lower). The cancer must show progression through rising PSA levels, worsening soft tissue disease, or new bone lesions. Participants need good physical function (ECOG 0 or 1), life expectancy of at least 12 months, and adequate organ function. Side effects from previous treatments must have improved to mild levels.
Main exclusion criteria: Female patients and vulnerable populations (those unable to give informed consent) are excluded.
Trial focus and goals: The study compares progression-free survival (time until cancer worsens) between patients receiving PF-06821497 with enzalutamide versus those receiving a placebo with enzalutamide. The trial is double-blind, meaning neither participants nor researchers know who receives the active drug. Regular monitoring includes physical examinations, blood tests, and imaging studies to assess disease progression and treatment side effects. The study also evaluates overall survival, time to pain progression, and quality of life.
Investigational drugs: PF-06821497 (Mevrometostat) is an experimental enzyme inhibitor taken orally that targets specific pathways involved in cancer cell growth. Enzalutamide is an established hormone therapy taken orally that blocks male hormone effects on cancer cells.
Summary
The 43 ongoing clinical trials for metastatic prostate cancer represent significant international research efforts, with studies concentrated primarily in Western and Central European countries. Notable patterns include multiple large trials testing combinations of hormone therapies with novel agents, particularly PARP inhibitors and immune checkpoint inhibitors. Several trials focus on sequencing questions - determining the optimal order and combination of treatments. A substantial number of studies target specific patient populations based on genetic markers, such as HRR gene mutations or BRCA status, reflecting the move toward personalized medicine. The geographic distribution shows strong participation from countries like Italy, Spain, France, and Germany, with many trials running across multiple nations to ensure adequate patient recruitment. Treatment approaches span from traditional chemotherapy to cutting-edge targeted therapies and immunotherapies, with particular emphasis on extending progression-free survival and improving quality of life for patients with advanced disease.
