Prostate cancer is the uncontrolled growth of cells in the prostate, a gland in the male reproductive system below the bladder. Early prostate cancer causes no symptoms. Most cases are detected after screening tests – typically blood tests for levels of prostate-specific antigen (PSA) – indicate unusual growth of prostate tissue. Diagnosis requires a biopsy of the prostate. If cancer is present, the pathologist assigns a Gleason score, with a higher score representing a more dangerous tumor. Medical imaging is performed to look for cancer that has spread outside the prostate. Based on the Gleason score, PSA levels, and imaging results, a cancer case is assigned a stage 1 to 4. Higher stage signifies a more advanced, more dangerous disease.
Nicholas J. Vogelzang was a medical oncologist with Comprehensive Cancer Centers of Nevada (CCCN). He serves as medical director of the Research Executive Committee and Associate Chair of the Developmental Therapeutics and Genitourinary Committees for US Oncology Research. His research interests include clinical trials for genitourinary malignancies and mesothelioma.
Satraplatin is a platinum-based antineoplastic agent that was under investigation as a treatment of patients with advanced prostate cancer who have failed previous chemotherapy. It has not yet received approval from the U.S. Food and Drug Administration. First mentioned in the medical literature in 1993, satraplatin is the first orally active platinum-based chemotherapeutic drug; other available platinum analogues—cisplatin, carboplatin, and oxaliplatin—must be given intravenously.
Abiraterone acetate, sold under the brand name Zytiga among others, is a medication used to treat prostate cancer. Specifically it is used together with a corticosteroid for metastatic castration-resistant prostate cancer (mCRPC) and metastatic high-risk castration-sensitive prostate cancer (mCSPC). It should either be used following removal of the testicles or along with a gonadotropin-releasing hormone (GnRH) analog. It is taken by mouth.
Enzalutamide, sold under the brand name Xtandi, is a nonsteroidal antiandrogen (NSAA) medication which is used in the treatment of prostate cancer. It is indicated for use in conjunction with castration in the treatment of metastatic castration-resistant prostate cancer (mCRPC), nonmetastatic castration-resistant prostate cancer, and metastatic castration-sensitive prostate cancer (mCSPC). It is taken by mouth.
Radium-223 is an isotope of radium with an 11.4-day half-life. It was discovered in 1905 by T. Godlewski, a Polish chemist from Kraków, and was historically known as actinium X (AcX). Radium-223 dichloride is an alpha particle-emitting radiotherapy drug that mimics calcium and forms complexes with hydroxyapatite at areas of increased bone turnover. The principal use of radium-223, as a radiopharmaceutical to treat metastatic cancers in bone, takes advantage of its chemical similarity to calcium, and the short range of the alpha radiation it emits.
Olaparib, sold under the brand name Lynparza, is a medication for the maintenance treatment of BRCA-mutated advanced ovarian cancer in adults. It is a PARP inhibitor, inhibiting poly ADP ribose polymerase (PARP), an enzyme involved in DNA repair. It acts against cancers in people with hereditary BRCA1 or BRCA2 mutations, which include some ovarian, breast, and prostate cancers.
Veliparib (ABT-888) is a potential anti-cancer drug acting as a PARP inhibitor. It kills cancer cells by blocking a protein called PARP, thereby preventing the repair of DNA or genetic damage in cancer cells and possibly making them more susceptible to anticancer treatments. Veliparib may make whole brain radiation treatment work more effectively against brain metastases from NSCLC. It has been shown to potentiate the effects of many chemotherapeutics, and as such has been part of many combination clinical trials.
Cabazitaxel, sold under the brand name Jevtana, is a semi-synthetic derivative of a natural taxoid. It is a microtubule inhibitor, and the fourth taxane to be approved as a cancer therapy.
Sipuleucel-T, sold under the brand name Provenge, developed by Dendreon Pharmaceuticals, LLC, is a cell-based cancer immunotherapy for prostate cancer (CaP). It is an autologous cellular immunotherapy.
Galeterone is a steroidal antiandrogen which was under development by Tokai Pharmaceuticals for the treatment of prostate cancer. It possesses a unique triple mechanism of action, acting as an androgen receptor antagonist, androgen receptor down regulator, and CYP17A1 inhibitor, the latter of which prevents the biosynthesis of androgens. As a CYP17A1 inhibitor, galeterone shows selectivity for 17,20-lyase over 17α-hydroxylase.
Seviteronel is an experimental cancer medication which is under development by Viamet Pharmaceuticals and Innocrin Pharmaceuticals for the treatment of prostate cancer and breast cancer. It is a nonsteroidal CYP17A1 inhibitor and works by inhibiting the production of androgens and estrogens in the body. As of July 2017, seviteronel is in phase II clinical trials for both prostate cancer and breast cancer. In January 2016, it was designated fast-track status by the United States Food and Drug Administration for prostate cancer. In April 2017, seviteronel received fast-track designation for breast cancer as well.
Apalutamide, sold under the brand name Erleada among others, is a nonsteroidal antiandrogen (NSAA) medication which is used in the treatment of prostate cancer. It is specifically indicated for use in conjunction with castration in the treatment of non-metastatic castration-resistant prostate cancer (NM-CRPC). It is taken by mouth.
Talazoparib, sold under the brand name Talzenna, is an orally available poly ADP ribose polymerase (PARP) inhibitor marketed by Pfizer for the treatment of advanced breast cancer with germline BRCA mutations. Talazoparib is similar to the first in class PARP inhibitor, olaparib. It was approved in October 2018, in the United States and June 2019, in the European Union for germline BRCA-mutated, HER2-negative locally advanced or metastatic breast cancer.
Ralaniten acetate is a first-in-class antiandrogen that targets the N-terminal domain (NTD) of the androgen receptor (AR) developed by ESSA Pharmaceuticals and was under investigation for the treatment of prostate cancer. This mechanism of action is believed to allow the drug to block signaling from the AR and its splice variants. EPI-506 is a derivative of bisphenol A and a prodrug of ralaniten (EPI-002), one of the four stereoisomers of EPI-001, and was developed as a successor of EPI-001. The drug reached phase I/II prior to the discontinuation of its development. It showed signs of efficacy in the form of prostatic specific antigen (PSA) decreases (4–29%) predominantly at higher doses (≥1,280 mg) in some patients but also caused side effects and was discontinued by its developer in favor of next-generation AR NTD inhibitors with improved potency and tolerability.
Elacestrant, sold under the brand name Orserdu, is an anticancer medication which is used in the treatment of breast cancer. It is taken by mouth.
N-Desmethylenzalutamide is a nonsteroidal antiandrogen (NSAA) and the major metabolite of enzalutamide, an NSAA which is used as a hormonal antineoplastic agent in the treatment of metastatic prostate cancer. It has similar activity to that of enzalutamide and, with enzalutamide therapy, circulates at similar concentrations to those of enzalutamide at steady state. N-Desmethylenzalutamide is formed from enzalutamide in the liver by the cytochrome P450 enzymes CYP2C8 and CYP3A4. It has a longer terminal half-life than enzalutamide.
Systemic Therapy in Advancing or Metastatic Prostate Cancer: Evaluation of Drug Efficacy (STAMPEDE) is a clinical trial investigating treatments for high risk or terminal prostate cancer. Recruitment started in 2005 and ends in 2022 and in January 2020, over 10,000 participants have joined the trial.
Amivantamab, sold under the brand name Rybrevant, is a bispecific monoclonal antibody used to treat non-small cell lung cancer. Amivantamab is a bispecific epidermal growth factor (EGF) receptor-directed and mesenchymal–epithelial transition (MET) receptor-directed antibody. It is the first treatment for adults with non-small cell lung cancer whose tumors have specific types of genetic mutations: epidermal growth factor receptor (EGFR) exon 20 insertion mutations.
Lutetium (177Lu) vipivotide tetraxetan, sold under the brand name Pluvicto, is a radiopharmaceutical medication used for the treatment of prostate-specific membrane antigen (PSMA)-positive metastatic castration-resistant prostate cancer (mCRPC). Lutetium (177Lu) vipivotide tetraxetan is a targeted radioligand therapy.
