简要总结
Background:
Metastatic castration sensitive and castration resistant prostate cancer (mCSPC and mCRPC) are prostate cancers that have spread to other parts of the body. Use of the drug docetaxel with androgen deprivation therapy can improve survival for men with mCSPC. Researchers want to see if combining this treatment with other drugs can help delay the time it takes for mCSPC and mCRPC to get worse.
Objective:
To learn if giving docetaxel with PDS01ADC is safe and effective for men with prostate cancer.
Eligibility:
Men age 18 and older with mCSPC or mCRPC.
Design:
Participants will be screened with a medical history and physical exam. Their diagnosis will be confirmed. Their symptoms and how well they do their normal activities will be reviewed. They will have blood and urine tests. Their heart will be evaluated. They will have imaging scans of the chest, abdomen, and pelvis. They will have bone scans with intravenous (IV) injections of Tc99 to check for tumor spread in the bones.
Some screening tests will be repeated during the study.
Participants may have tumor biopsies.
Participants will get treatment in cycles. Each cycle will last 21 days. They will get docetaxel through IV infusion. They will get PDS01ADC as an injection under the skin.
Participants with mCSPC will have up to 6 cycles. Those with mCRPC will be treated until they cannot tolerate the side effects or their disease gets worse.
Participants will have a follow-up visit 30 days after treatment ends. Those with mCSPC will then have follow-up visits at the clinic every 3 months.
详细描述
Background:
- A phase III trial demonstrated that combining docetaxel and androgen deprivation therapy (ADT) significantly improved survival (57.6 vs 44.0 months (hazard ratio HR=0.56, (0.44- 0.70), p <0.0001) for men with metastatic castration sensitive prostate cancer (mCSPC). The greatest benefit was seen in men with high volume disease (visceral disease or 4+ bone lesions with at least one beyond the pelvis and spine.)
- Docetaxel has limited efficacy in metastatic castration resistant prostate cancer (mCRPC) patients who have already progressed on anti-androgen therapy (abiraterone or enzalutamide).
- Intensification of treatment in de novo mCSPC patients by adding abiraterone to docetaxel and ADT has been shown in a phase III trial to significantly improve OS (0.82, (0.69 - 0.98) p=0 (Summation)030) and rPFS (HR=0.54,(0.41-0.71) p <0.0001)
- Clinical data have indicated that PSA <=0.20 ng/ml eight months after starting androgen deprivation therapy (ADT) is prognostic for overall survival based on data from the phase III trial.
- Preclinical data demonstrates that docetaxel increases uptake of PDS01ADC, an IL-12 immunocytokine that targets necrosis.
- Additional preclinical data demonstrates the potential anti-tumor synergy of PDS01ADC when combined with docetaxel.
Objectives:
Phase I:
To evaluate safety and tolerability of docetaxel in combination with PDS01ADC in participants who have metastatic prostate cancer.
