Preclinical data supports disruption of AR regulated gene transcription, even in the presence of resistance mechanisms including ligand-binding domain point mutations and truncated splice variants, as a strategy to inhibit prostate cancer growth. In the Phase 1a dose-escalation study (NCT04421222), treatment with EPI-7386 monotherapy was safe, well tolerated up to a daily dose of 1200 mg (600 mg BID), achieved target clinical exposures and showed preliminary signals of antitumor activity in heavily pretreated mCRPC. We report here the results of the Phase 1b dose expansion first-in-human trial of EPI-7386 in mCRPC.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;This Phase 1b, open-label, multicenter, dose expansion trial was designed to evaluate the safety, pharmacokinetics, pharmacodynamics, and antitumor activity of EPI-7386 in mCRPC patients (pts) progressing on standard of care treatment, including next generation antiandrogens. Two cohorts were tested, examining the 600 mg BID and 600 mg QD dosing regimens. Circulating Tumor DNA (ctDNA) samples were also collected in the study at baseline and at cycle 4 to characterize the tumor genomic profile and quantify molecular response.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;12 pts were enrolled in the 600 mg BID cohort (median follow up 12 months) and 12 in the 600 mg QD cohort (median follow up 8 months). Pts in both arms had a median of 2 (range 1-3) lines of prior therapy for mCRPC: 71% in both cohorts received abiraterone and at least one second generation AR inhibitor (enzalutamide, darolutamide or apalutamide). EPI-7386 was safe and well tolerated at both dosing schedules. The majority of related adverse events (AEs) were grade 1 (47%), and grade 2 (41%). AEs were consistent with AEs associated with second-generation antiandrogens (i.e. anemia, fatigue and hypertension), and no differences were observed between EPI-7386 600 mg QD and BID dosing. As expected, 600 mg BID dosing resulted in higher PK parameters at steady state, with a mean AUC&lt;sub&gt;0-24&lt;/sub&gt; of 357,000 hr*ng/mL and a mean C&lt;sub&gt;last&lt;/sub&gt; of 14,500 ng/mL, in comparison to a mean AUC&lt;sub&gt;0-24&lt;/sub&gt; of 246,000 hr*ng/mL and a mean C&lt;sub&gt;last&lt;/sub&gt; of 7,120 ng/mL for the 600 mg QD cohort.

Studies suggest that the validity of PSAV thresholds varies depending on the demographics of the patient population. Few studies investigate how PSAV and PSADT can be used to stratify prostate cancer risk in black populations. Black men have the highest incidence of prostate cancer out of any group in America.

The cancer cohort was stratified to adjust for treatment (N=126, 81%). PSAV calculation used untransformed PSA values that met the previously mentioned inclusion criteria.

In the U.S., the incidence is approximately 1 per 250 males, showing a rise over recent decades, while mortality rates have decreased. For stage I or IIA nonseminomatous germ cell tumors, primary retroperitoneal lymph node dissection (RPLND) provides crucial therapeutic and diagnostic benefit due to the tumor's limited metastatic spread. Disparities persist in testicular cancer outcomes partly due to limited access to high volume specialty surgical care, and based on race and ethnicity with increased mortality noted for Hispanic men. This study aims to explore these disparities further by analyzing clinical outcomes, including presentation and surgical management, across rural and urban areas using the National Cancer Database (NCDB), to better understand how geographical factors influence testicular cancer outcomes.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;Our retrospective study, utilizing the NCDB, explores disparities in testicular cancer outcomes among men diagnosed with seminoma (SGCT) and nonseminomatous germ cell tumors (NSGCT).

It accounts for approximately 1% of all male cancers but has a high survival rate if detected early. Testicular cancer can have significant implications for fertility and quality of life, making it a critical area of focus for public health and clinical research. Despite advancements in treatment, disparities in outcomes exist based on various demographic and hospital-related factors. This study aims to estimate the prevalence, mortality rate, hospital length of stay (LOS), and total hospitalization charges for patients with testicular cancer using the National Inpatient Sample (NIS) data from 2021.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;We conducted a retrospective analysis using the NIS dataset, which included 6,666,752 observations. Testicular cancer cases were identified using the appropriate ICD-10 code. Survey procedures (svy) were utilized to account for the complex survey design of the NIS. The primary outcome of interest was in-hospital mortality, while secondary outcomes included hospital length of stay (LOS) and total hospitalization charges (TOTCHG). Descriptive statistics and regression analyses were performed to examine the associations between testicular cancer and these outcomes. Independent variables included age, gender, race, zip code income quartile, Charlson Comorbidity Index, weekend admission, hospital region, teaching status, and bed size.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;The total number of testicular cancer cases was estimated to be 8,225 (95% CI: 7,434 - 9,016). The crude total of in-hospital deaths among testicular cancer patients was 265 (95% CI: 192 - 338), resulting in a mortality rate of 3.22% (95% CI: 2.45% - 4.23%). Adjusted logistic regression analysis revealed significant associations with the Charlson Comorbidity Index (Odds Ratio [OR] = 1.390, p &lt; 0.001) and hospital teaching status (OR = 0.468, p = 0.043), while patients identified as Asian/Pacific Islander had a significantly higher odds ratio (OR = 6.210, p = 0.004).&lt;/div&gt;&lt;div&gt;The mean LOS for testicular cancer patients was 6.44 days (95% CI: 6.07 - 6.82).

The mean total hospitalization charges for testicular cancer patients were $88,194 (95% CI: $80,853 - $95,536).

In theory, the success of the procedure relies on having the disease confined within the dissected lymph nodes with no presence of any undetected organ metastatic disease outside the surgical margins. While SGCT characteristics and behavior have been well described in comparison to non-seminoma germ cell tumors (NSGCT), quantifying the probability and absolute causal effect of SGCT subtype in having advanced metastatic disease (i.e., Stage III) compared to NSGCT has not been described using large national dataset yet. Therefore, we aim to quantify and describe this relationship using the National Cancer Database (NCDB).</div></div><div><h3>Methods</h3><div>We utilized inverse propensity score weights (IPTW) calculated by age, primary tumor characteristics, patient sociodemographic, regional and facility level, and year of diagnosis to run a multivariable IPTW-weighted logistic regression model (MVA) for the outcome of stage III (vs. stage I/II) to estimate the odds ratio of SGCT presenting with stage III. Then, we utilized IPTW to estimate the absolute average causal effect of SGCT v.s.

Our IPTW-MVA showed that SGCT is significantly less likely to present with stage III disease compared to NSGCT after accounting for all available covariates (OR: 0.303, [95%CI; 0.278 – 0.330], p&lt;0.0001), based of the same model we estimated the mean causal effect of presenting as stage III to be significantly less likely in SGCT compared to NSGCT by 66.41% if all other patients parameters and variables were the same (- 62.41% [95%CI: - 65.00%, -59.82%], p&lt;0.0001).</div></div><div><h3>Conclusions</h3><div>Our results strongly validate the use of primary-RPLND in SGCT as opposed to NSGCT, as SGCT are 62.41% less likely to present with advanced stage given the same parameters in NSGCT. In addition torecent favorable clinical trial results, primary RPLND in carefully selected SGCT patients should be highly considered to avoid long-term complications associated with other treatment modalities.</div></div>","PeriodicalId":23408,"journal":{"name":"Urologic Oncology-seminars and Original Investigations","volume":"43 3","pages":"Pages 36-37"},"PeriodicalIF":2.4,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143509947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
