Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

For non central nervous system (CNS) cancers, patients with symptomatic CNS involvement of his/her cancer. Subjects with stable neurological function, on stable doses of steroids/anti-epileptics over 4 weeks, and with no evidence of CNS progression within 12 weeks prior to study entry are eligible; 5. History of another malignancy within 2 years prior to registration unless adequately treated and determined free of progressive and metastatic disease for at least 6 months. Patients with a past history of adequately treated carcinoma-in-situ, basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or superficial transitional cell carcinoma of the bladder are eligible; 6. Pregnancy, lactation, or inadequate contraception. Women must be post-menopausal, infertile, or use a reliable means of contraception. Women of childbearing potential must have a negative pregnancy test done within 7 days prior to registration. Men must have been surgically sterilised or use a barrier method of contraception (double barrier, if required). 7. Known history of hypersensitivity to active or inactive components of seviteronel, dexamethasone, and/or GnRH analoge; 8. Previous treatment with seviteronel or same class of agent; 9. Treatment with any of the following anti-cancer therapies prior to the first dose of study treatment:
- - Radiation therapy, surgery or tumour embolization within 14 days prior to the first dose of study treatment.
- - Immunotherapy within 28 days prior to the first dose of study treatment; - Chemotherapy, biologic therapy, or hormonal therapy within 14 days or 5 half-lives of a drug prior to the first dose of study treatment or until recovery from previous therapy (whichever is longer); 10.
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

|Solid Tumor, Androgen Receptor Gene Overexpression|
Background: The human androgen receptor (AR) is a steroid hormone receptor that is expressed in multiple reproductive tissues and has important effects on multiple organ systems. The AR is a major target for the treatment of prostate cancer, and, more recently, for treatment of breast cancer. However, the AR is also expressed on many other tissues and plays vital roles in other cancer types, such as head and neck cancers (eg, salivary gland and thyroid cancers), cutaneous malignancies (eg, melanoma and basal cell carcinoma), sarcomas, and genitourinary cancers (eg, renal and bladder cancers). There are very few studies investigating AR-targeted therapies for indications other than prostate or breast cancer; however the few anecdotal reports and small studies that have been performed suggest that AR-positive tumours may respond to therapy with AR-targeted agents. In this study we are concentrating on GBM Seviteronel is a dual selective P450C17,20-lyase (CYP17 lyase) and AR inhibitor currently being investigated in Phase 1/2 trials for prostate and breast cancers. Seviteronel has shown promising preclinical activity in some breast cancer models, and seviteronel in combination with dexamethasone (SEVI-D) has shown promising preliminary activity for treatment of metastatic castration-resistant prostate cancer. Therefore, SEVI-D could be beneficial for the treatment of other cancers that are known to be AR-positive such as GBM Aim: The overall aim is to facilitate and expedite the clinical testing of rational therapeutic hypotheses in a population with advanced cancer and unmet need, with a particular, but not exclusive, focus on rare or neglected cancers. The program will evaluate the clinical activity of SEVI-D in subjects with AR-positive GBM Primary Objective: To test the clinical activity of novel targeted treatments and/or indications as measured by objective tumour response or the ratio of time-to-progression on study over the preceding period Secondary Objectives: 1. Overall survival (OS) (death from any cause); 2. Safety and tolerability of treatment (rates of adverse events) 3. Health related quality of life during treatment (EORTC QLQ-C30v.3 questionnaire or brief pain inventory, if applicable). 4. To evaluate the feasibility, efficiency and utility of an overarching framework protocol for multiple, parallel signal-seeking clinical substudies; 5. To evaluate a mechanism for screening patients for actionable biomarkers to be used to guide therapy. Population: Patients with AR-positive GBM as confirmed by immunohistochemistry. Treatments: Seviteronel, will be administered orally at 450 mg (3 x 150 mg tablets) for men with 0.5 mg dexamethasone (tablet) once daily plus a GnRH analogue (depot injection). Seviteronel, will be administered orally at 450 mg (3 x 150 mg tablets) for post menopausal women, once daily in combination with once daily 0.5 mg dexamethasone (tablet). For premenopausal women (with intact ovaries), a GnRH analogue (depot injection) will also need to be admistered. See Treatment Study Table below. Patients will take seviteronel and dexamethasone each day continuously in 28-day cycles. Assessments: Screening for participation in the screening platform includes the review of patient history, current health status, availability of a biospecimen for AR screening and patient willingness to be in a trial if eligible. Clinical and safety assessments are scheduled prior to registration and then every 8 weeks until death. Imaging and other response assessments are required at baseline and 8-weekly from cycle 1 day 1 until progression. Blood collection for translational studies will occur at: 1. Baseline (collected within 21 days prior to registration) or within 28 days of C1D1 treatment 2. Every 2nd cycle 3. At End of treatment
Experimental: Adrogen Postive Solid Tumours
Drug: - SEVI-D (Seviteronel in combination with dexamthasone)
Use of SEVI-D (Serivteronel and dexamethasone) in the treatment of androgen receptor positive solid tumours. Serivteronel will be administered orally at 450 mg (3 tables) once daily. It will be given in combination with one oral tablet of 0.5 mg tablet of Dexamethosone. SEVI-D will be continuously administered daily while on the study. Clinical and safety assessments are scheduled every 4 weeks during the study and then every 8 weeks after the end of the safety follow up period of the study.
