Targeting Androgen Signaling in Urothelial Cell Carcinoma - Neoadjuvant

Annually, over 80,000 people will be diagnosed with urothelial cell carcinoma (UCC) of the bladder in the USA, with over 17,000 deaths. For patients with muscle-invasive disease (stage II and IIIA), standard of care therapy is neoadjuvant chemotherapy followed by radical cystectomy. Neoadjuvant chemotherapy has been shown by multiple clinical trials and meta-analyses to improve pCR rates, disease free survival, and overall survival when compared to cystectomy alone. Specifically, neoadjuvant gemcitabine/cisplatin has been shown to be tolerable and effective and is a level 1 recommendation for treatment of muscle invasive bladder cancer by the National Comprehensive Cancer Network Guidelines. The presence of a pCR in response to neoadjuvant chemotherapy is prognostic, but only about 35% of patients achieve a pCR. Thus improved neoadjuvant chemotherapy regimens are necessary to improve recurrence free survival and overall survival rates in patients with bladder cancer. UCC is more common in men than women, with incidence rates of 3:1 to 4:1. This disparity persists even after controlling for smoking and occupational hazards/exposures and is likely influenced by androgen signaling. Androgen receptor (AR) positive UCC cells display increased proliferation, migration, and invasion in the presence of androgen and these effects are nullified in the presence of an AR antagonist. Preclinical studies show decreased rates of UCC incidence in response to a chemical carcinogen in castrated mice versus sham castrated mice and AR knockout mice versus AR intact mice. In retrospective human studies patients with UCC receiving androgen targeted therapy for concurrent prostate cancer had approximately 50% lower recurrence rates of UCC. Similarly, men receiving androgen targeted therapy for prostate cancer or benign prostatic hyperplasia have lower incidence rates of UCC than men not receiving androgen directed therapy. Two prospective human clinical trials related to this concept have been performed. The first evaluated enzalutamide (an AR antagonist) as chemoprevention in non-muscle invasive UCC. This study was closed due to poor accrual after accruing only one patient. The second study added enzalutamide to standard chemotherapy in patients with metastatic UCC. Seven patients accrued at the therapeutic dose of enzalutamide. Overall, there was no signal for increased efficacy. However, one patient achieved a complete response lasting 2 years at last report. This patient was noted to have >90% positivity for AR in their tumor and, notably, was the only woman to participate in the study (and presumably had low testosterone levels). These data support further evaluation of androgen targeted therapy in AR+ UCC. TASUC-neo is a pilot study conducted in patients with androgen receptor positive (AR+), pT2 - pT4, N0 - N1, M0 urothelial cell carcinoma (UCC) of the bladder. The study medication, Degarelix, will be administered concurrently with neoadjuvant gemcitabine/cisplatin.

ETHAN - ET for Male BC

This is an open-label, multicenter, randomized trial for men with stage I-III hormone receptor-positive (HR+)/HER2-negative breast cancer. The trial will have two phases: A 3-week window phase containing endocrine therapy followed by a 4-month treatment phase where participants are treated with one of four endocrine therapy treatment combinations. Tamoxifen is the standard of care for the treatment of breast cancer in men. Anastrozole is a standard treatment in women with breast cancer and works more effectively than tamoxifen. This study hopes to learn if anastrozole may also be effective in men. Given that gonadal suppression and CDK 4/6 inhibitors have both improved treatment in women with breast cancer, the study hopes to learn how the addition of Degarelix (gonadal suppression) and Abemaciclib (CDK 4/6 inhibitors) work in comparison to standard of care tamoxifen. The research study procedures include screening for eligibility and study treatment including laboratory evaluations and quality of life questionnaires. After completion of treatment, participants will be followed for up to 10 years It is expected that about 60 men will take part in this research study. Eli Lilly, a pharmaceutical company, is supporting this research study by providing one of the study drugs. This study is also being supported by Johns Hopkins University on behalf of the Translational Breast Cancer Research Consortium (TBCRC).

Cardiometabolic Consequences of the Loss of Ovarian Function

Menopause accelerates cardiovascular disease (CVD) risk due to adverse changes in risk factors (e.g., increased body fat) and vascular health, related to changes in the hormone environment. The investigators showed that measures of vascular health progressively worsen across the menopause transition, related to increased oxidative stress. The oxidative stress-mediated vascular dysfunction was related to the loss of estrogen. The loss of estrogen with menopause also causes an increase in percent body fat levels, particularly in the abdominal region. However, it is unknown if the increase in abdominal body fat worsens vascular dysfunction with the loss of estrogen. Thus Aim 1 of Project 1 will investigate the impact of increased abdominal adiposity superimposed on the direct effects of estrogen deficiency on vascular function in women. In collaboration with SCORE Projects 2 and 3, Aim 2 and an Exploratory aim will investigate the underlying causes for the increase in abdominal body fat and vascular dysfunction. There is emerging evidence that links the tryptophan-kynurenine (TRP-KYN) pathway as a regulator of vascular function, body fat and the aging process. TRP is an essential amino acid that is metabolized to KYN and various metabolites. KYN and some of its breakdown products have been associated with an increase in body fat and an impairment in vascular function. It is unknown if estrogen regulates this pathway. Thus, Aim 2 and the Exploratory aim will investigate if the TRP-KYN pathway is dysregulated with the loss of estrogen, and if this is associated with an increase in abdominal body fat and an impairment in endothelial function. The Aims of Project 1 will be accomplished by conducting an intervention trial in premenopausal women randomized to a low estrogen condition (gonadotropin releasing hormone antagonist, GnRHant, plus a placebo patch) or a high estrogen condition (GnRHant plus an estrogen patch) to isolate the actions of estrogen. Women will wear a patch daily that will be switched out weekly. At weeks 9 and 17, women will receive 5 mg of medroxyprogesterone acetate (MPA) for 12 days to prevent endometrial hyperplasia. Outcomes will be assessed before the intervention and after 2 and 20 weeks of the intervention, except where indicated. All women will continue their intervention until testing has been completed. Initially, women interested in the study will undergo a phone or e-mail screening to assess likelihood for eligibility.

Androgen Deprivation, With or Without pTVG-AR, and With or Without T-Cell Checkpoint Blockade, in Patients With Newly Diagnosed, High-Risk Prostate Cancer

The original design of this protocol was to examine the use of a plasmid DNA vaccine encoding Androgen Receptor (AR), alone or with nivolumab, to induce and/or augment therapeutic T-cells following androgen deprivation in participants with newly diagnosed prostate cancer scheduled to undergo prostatectomy in one of three treatment arms. Based on emerging preclinical data that the timing of PD-1 blockade with the first immunization may be critical, and that combining PD-1 and LAG-3 blockade can improve the anti-tumor efficacy of vaccination in murine models of prostate cancer, the trial was amended to include two additional treatment arms testing the timing of PD-1 blockade and the addition of LAG-3 blockade. All participants will receive treatment with degarelix for 8 weeks prior to prostatectomy. In the first part of the study encompassing the first 3 treatment arms, participants will be also be randomized to receive either no additional treatment, a DNA vaccine encoding AR, or a DNA vaccine encoding AR and nivolumab. The additional arms will randomize patients to receive cemiplimab (PD-1 antagonist) with vaccine or cemiplimab with fianlimab (LAG-3 antagonist) and vaccine, with each agent initiated with the first immunization. Participants receiving vaccination will begin that treatment prior to degarelix, based on preclinical findings that this may be a preferred sequence of treatment. The overall goal is to determine whether a DNA vaccine can augment the number of prostate tumor-specific infiltrating CD8+ T cells elicited with androgen deprivation, and whether this might be further augmented by combination with T-cell checkpoint blockade. Because these cells should have cytolytic effector function, the primary clinical endpoint is pathological response (pCR and secondarily MRD) at the time of prostatectomy. This endpoint was chosen based on observations from previous clinical trials evaluating androgen deprivation therapies alone in this setting. Safety will also be a primary objective of the current study, as this vaccine and nivolumab have not been previously used in this early stage population. An additional secondary clinical endpoint will be 1-year PSA progression-free survival, after completion of all therapy, and with evidence of testosterone recovery. Laboratory and correlative endpoints will include whether vaccination, with or without concurrent T-cell checkpoint blockade, elicits greater numbers of CD8+ tumor-infiltrating lymphocytes, and whether AR-specific prostate tissue-infiltrating CD8+ T cells and persistent systemic immunity are detectable after treatment with vaccination. Other correlative studies will evaluate FLT PET/CT (Arms 1-3) as an investigational means of specifically identifying tumor infiltration by proliferating T cells as an early marker of treatment response, and whether uptake in other normal tissues is associated with autoimmune toxicity. While this is a relatively small trial, given a focus on correlative endpoints, a phase 2 expansion design was chosen to further evaluate the safety and clinical efficacy if pathological responses are observed in the initial part of the trial. If pathological responses exceeding 20% are observed, this will be considered significantly different from what has been historically observed, and would justify proceeding with future larger studies evaluating these combination approaches in the neoadjuvant stage of prostate cancer. Primary Objectives: 1. To evaluate the safety of androgen deprivation and pTVG-AR DNA vaccine, alone or in combination with T-cell checkpoint blockade, in patients with newly diagnosed prostate cancer 2. To determine if pathological complete responses or minimal residual disease (MRD) can occur in patients with prostate cancer treated with androgen deprivation and pTVG-AR, alone or in combination with T-cell checkpoint blockade, prior to definitive surgery Secondary Clinical Objective: 1. To estimate 1-year PSA progression-free survival (post-prostatectomy) 2. To determine whether treatment with androgen deprivation and pTVG-AR DNA vaccine, alone or in combination with T-cell checkpoint blockade, leads to residual cancer burden (RCB) <0.25 cm3 at the time of prostatectomy 3. To determine the median progression-free survival Laboratory / Correlative Objectives: 1. To evaluate whether treatment with pTVG-AR elicits persistent systemic AR-specific Th1-biased T-cell responses 2. To determine whether treatment with androgen deprivation and pTVG-AR elicits greater numbers of prostate tissue-infiltrating CD8+ T cells compared with androgen deprivation alone, and whether this is augmented with nivolumab, cemiplimab, or cemiplimab and fianlimab 3. To determine if vaccination with pTVG-AR elicits AR-specific tumor-infiltrating CD8+ T cells 4. To determine whether PD-1 +/- LAG-3 blockade treatment with androgen deprivation and vaccine increases the frequency of CD8+ T cells with memory and effector function, relative to exhausted phenotype, compared with androgen deprivation and vaccine alone 5. To determine whether treatment elicits changes detectable by FLT PET imaging (Arms 1-3) 6. To determine whether LAG-3 with PD-1 blockade and vaccination (Arm 5) elicits greater CD8 T cell infiltration compared to PD-1 blockade and vaccination alone (Arm 4) 7. To determine whether prostate-tumor infiltrating T cells can be expanded and recognize AR

Talazoparib With Androgen Deprivation Therapy and Abiraterone for the Treatment of Castration Sensitive Prostate Cancer

PRIMARY OBJECTIVES: I. Increase the efficacy of first-line therapy for men with metastatic castration-sensitive prostate cancer by adding the PARP inhibitor talazoparib to standard therapy with androgen deprivation therapy (ADT) + abiraterone acetate (abiraterone). II. Study the efficacy of abiraterone and talazoparib in an ethnically diverse population. III.

OUTLINE: Patients receive talazoparib orally (PO) once daily (QD), abiraterone acetate PO QD, and prednisone PO QD on days 1-28. Patients also receive androgen deprivation therapy consisting of degarelix subcutaneously (SC) on day 1; leuprolide acetate intramuscularly (IM) on day 1 and bicalutamide PO QD on days 1-28 of cycle 1 and then leuprolide acetate IM on day 1 of subsequent cycles; leuprolide acetate IM on day 1 and bicalutamide PO QD on days 1-28 of cycle 1 and then leuprolide acetate IM on day 1 of cycles 2, 5, 8, and 11; or goserelin acetate SC monthly or every 3 months. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 30 days.

Radiotherapy Combined With a LHRH (Ant)Agonist Versus Apalutamide in Patients With Biochemical Recurrence After RP

After radical prostatectomy, around one third of patients will have biochemical progression. Salvage radiotherapy (SRT) is still potentially curative, but about 40-50% of patients will progress further. Recently, success rates of SRT were significantly improved through the use of concomitant anti-androgen (AAT) or androgen-deprivation (ADT) therapy. In RTOG 96-01, 2 years of bicalutamide 150 mg resulted in a 5% overall survival benefit at 12-years. In GETUG-AFU 16, 5-year progression-free survival was significantly improved when SRT was combined with 6 months of an LHRH agonist. Based on GETUG-AFU 16, most radiation oncologists now combine SRT with at least 6 months of ADT. However, ADT comes with several serious side-effects, both physical (cardiovascular, metabolic, musculoskeletal) and psychological (sexual, emotional and cognitive). It appears worthwile to look for alternatives in the form of AAT. In that respect, apalutamide, a potent competitive and purely antagonistic second-generation anti-androgen, is the ideal candidate. This trial is a phase II randomized, open-label study comparing salvage radiotherapy in combination with 6 months of ADT (arm A) versus AAT with apalutamide 240mg daily (arm B) in hormone-naïve patients with biochemical progression after radical prostatectomy. All subjects will receive salvage radiotherapy as standard of care and will be randomly assigned in a 1:1 ratio to receive either 6 months of ADT with LHRH agonist or antagonist through 6 monthly, two 3-monthly or one 6-monthly injections (control arm A) or 6 28-day cycles of apalutamide 240mg daily (interventional arm B). The study will include a screening phase, treatment phase, and a post-treatment phase. 1. Screening phase: allows for assessment of subject eligibility up to 35 days prior to randomization. 2. Treatment phase: includes the hormonal treatment for 6 months, to be started at the most 2 weeks after randomization and standard salvage radiotherapy. During the treatment phase, patients will have 3 study visits: 1. treatment initiation visit: first injection of LHRH (ant)agonist (arm A) or cycle 1, day 1 (C1D1) of apalutamide (arm B). 2. Concurrent with RT visit: if necessary (depending on product prescribed) injection of LHRH (ant)agonist (arm A) or cycle 4, day 1 (C4D1) of apalutamide (arm B). 3. End of treatment visit: at the end of the 6 months of hormonal therapy. 3. Post-treatment phase: will begin after a subject completes the treatment phase and the end of treatment visit and will continue until the primary endpoint is reached, i.e. the 9-months (3 months after end of treatment visit) EPIC-26 sexual domain score. The primary objective of the trial is to compare sexual function between the 2 groups based on the EPIC-26 sexual domain (0 - 100 scale, with higher scores representing better sexual function) at 9 months after start of hormonal treatment (primary endpoint). The following secondary endpoints will be explored: 1. Quality of life: assessed using EPIC-26 as well as the EORTC quality of life questionnaires C30 and PR25 as well as FACT-P. 2. Toxicity: will be assessed using the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. 3. Efficacy: prostate-specific antigen (PSA) response rates, defined as a decline from baseline in PSA level of 80% or greater, as well as PSA complete response rates, defined as a decline from baseline in PSA level of 90% or greater, will be prospectively collected at the 4 treatment visits. At this point in time, no study has directly compared apalutamide to LHRH agonists or antagonists in combination with SRT. This trial may be a preamble to the design of a registration trial in such patients or indeed patients with a intermediate and high-risk localized disease that are scheduled for EBRT or brachytherapy as radical treatment and also benefit from 6 months of hormonal treatment.
