However, given the growing costs and complexities of early-phase trials, trial activation and enrollment barriers may be greatest for these studies at healthcare facilities that provide care to the most diverse patient groups, including those in historically underserved communities (e.g., safety-net healthcare systems). To promote diverse and equitable access to early-phase cancer clinical trials, we are implementing a novel program for the transfer of care to enhance access to early-phase cancer clinical trials. We will then perform a mixed-methods study to determine perceptions and impact of the program. Specifically, we will screen, recruit, and enroll diverse patients from an urban, integrated safety-net healthcare system to open and active early-phase clinical trials being conducted in a university-based cancer center. To evaluate this novel program, we will: (1) determine program impact and efficiency; and (2) determine stakeholder experience with and perceptions of the program. To achieve these goals, we will conduct preliminary cost analyses of the program. We will also conduct surveys and interviews with patients and caregivers to elucidate program impact, challenges, and areas for improvement. We hypothesize that broadening access to early-phase cancer trials conducted at experienced centers may improve equity and diversity. In turn, such efforts may enhance the efficiency and generalizability of cancer clinical research.</p></div>","PeriodicalId":37937,"journal":{"name":"Contemporary Clinical Trials Communications","volume":"39 ","pages":"Article 101292"},"PeriodicalIF":1.5,"publicationDate":"2024-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2451865424000395/pdfft?md5=3cc23e5e9c345fabd1afdaea296dc5b6&pid=1-s2.0-S2451865424000395-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140539222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pre-menstrual disorders are associated with debilitating symptoms that onset in the days prior to menses. A complex interplay between hormonal fluctuations, cellular sensitivity, and psychosocial stressors likely underly the pathophysiology of pre-menstrual disorders. Current treatment options include selective serotonin reuptake inhibitors, hormonal therapies, and psychosocial support. There is growing evidence for oestrogen, progesterone, gonadotropin Releasing Hormone analogues and Complementary and Alternative Medicines in treating Pre-menstrual disorders. (S)–S-adenosylmethionine is a complementary and alternative medicine with postulated roles in the treatment of depression, with a rather rapid onset of action and minimal side effect profile. We propose a protocol for investigating the efficacy of (S)–S-adenosylmethionine in the treatment of pre-menstrual disorders. The proposed study is an open label pilot study, that will recruit thirty women between the ages of 18–45 who experience a pre-menstrual disorder. Daily and interval questionnaires will provide a quantification of symptoms across four menstrual cycles (16 weeks). During two consecutive menstrual cycles it is proposed that participants receive oral (S)–S-adenosylmethionine Complex 400 mg three times a day (total daily dose 1200 mg), during the pre-menstrual time-period (14 days prior to menses). Changes in pre-menstrual disorder symptoms between control and treatment cycles will assist in elucidating the clinical efficacy of (S)–S-adenosylmethionine.
