<b><i>Introduction:</i></b> Radiation dermatitis (RD) is a side effect of radiation therapy (RT) which is experienced by over 90% of patients being treated for breast cancer. The current clinical trial was conducted to measure the preventative effects of a boron-based gel on several different clinical outcomes (dermatitis, erythema, dry desquamation, and moist desquamation) after 25 radiotherapy sessions. <b><i>Methods:</i></b> This research used a double-blind parallel-group design with a placebo control (<i>n</i> = 76) and randomized group (<i>n</i> = 181), with all participants being between 18 and 75 years old. Fifteen minutes before each radiotherapy, participants in the intervention group were given a gel containing 3% sodium pentaborate pentahydrate, while those in the placebo group received a gel with no chemical substance. Dermatitis, erythema, dry desquamation, and moist desquamation were compared between the 2 groups. <b><i>Results:</i></b> At baseline, there were no significant differences between the groups (<i>p</i> &#x3e; 0.05), except for body mass index. After 14 days of treatment, dermatitis (98.7% vs. 9.9%; <i>p</i> &#x3c; 0.001), erythema (96.1% vs. 12.2%; <i>p</i> &#x3c; 0.001), dry desquamation (50% vs. 3.9%; <i>p</i> &#x3c; 0.001), and moist desquamation (18.4% vs. 0.6%; <i>p</i> &#x3c; 0.001) were much more common in the placebo group than the intervention group. To prevent dermatitis, erythema, dry desquamation, and moist desquamation in 1 patient, on average, 1.1 (95% confidence interval [CI]: 1.1–1.2), 1.2 (95% CI: 1.1–1.3), 2.2 (95% CI: 1.7–2.9), and 5.6 (95% CI: 3.8–11.0) patients need to be treated, respectively. <b><i>Conclusion:</i></b> The boron-based gel has a significant preventive effect on several categories of RD which might be used by clinicians in breast cancer.

TPS5606 Background: Oregovomab binds tumor-associated CA125 rendering the target antigen CA125 more immunogenic or “neoantigen-like” through altered and enhanced antigen processing and presentation to specific T cells. This phenomenon is hypothesized to bypass tumor-associated immune suppression when administered in combination with chemotherapy. In a randomized phase II study, immunization with oregovomab in a schedule-dependent combination with paclitaxel and carboplatin induced tumor immunity and demonstrated significant improvement in PFS (median (months) 41.8 PCO vs 12.3 PCP, HR 0.44 p = 0.0027, and OS median N.E. PCO vs 43.2 PCP HR O.34 (p = 0.0077)) in patients with previously untreated EOC. The FLORA-5, the definitive confirmatory global registration trial, is currently recruiting patients in the front-line setting. Methods: The study is a phase 3, multicenter, double-blind, placebo-controlled clinical trial. Optimally debulked patients with FIGO III/IV EOC and serum CA125 > 50 U/ml receiving adjuvant (Cohort 1) or neoadjuvant (Cohort 2) chemotherapy will be randomized post-surgery to paclitaxel and carboplatin with or without oregovomab. Patients with germline BRCA1/2 mutations will be excluded. Chemotherapy will be administered every 3 weeks in both cohorts. Oregovomab/placebo is administered simultaneously at cycles 1, 3, and 5 of chemotherapy with a single maintenance dose at 12 weeks following cycle 5 in Cohort 1. Neoadjuvant patients (Cohort 2) will be administered oregovomab/placebo post interval debulking surgery at cycles 4 and 6 with maintenance doses at 6- and 18-weeks following cycle 6. No other post front-line maintenance therapy is permitted. The primary objective is PFS determined by RECIST 1.1 criteria. Cohort 1 will recruit 372 patients with a 90% power to detect a difference with an alpha of 0.025 and a hazard ratio of 0.65 when 252 PFS events have been observed. Cohort 2 will be analyzed separately recruiting 232 patients with a 90% power to detect a difference with an alpha of 0.025 and a hazard ratio of 0.60 when 165 PFS events have been observed. An interim analysis for futility will be performed. Secondary objectives include OS, frequency and severity of adverse events, and quality of life. Exploratory objectives include iRECIST, TFST, TSST, PFS2, and evaluation of potential biomarkers. The study is actively enrolling in the US with 9 patients enrolled at time of submission. Centers in Europe, South America and Asia are expected to begin accruing shortly. Clinical trial information: NCT04498117.

Objective. To evaluate the effects of ezetimibe/simvastatin (EZE/SIMV) and rosuvastatin (ROSUV) on oxidative stress (OS) markers in patients with diabetic polyneuropathy (DPN).Methods. We performed a randomized, double-blind, placebo-controlled phase III clinical trial in adult patients with Type 2 Diabetes Mellitus (T2DM) and DPN, as evaluated by composite scores and nerve conduction studies (NCS). Seventy-four subjects with T2DM were allocated 1 : 1 : 1 to placebo, EZE/SIMV 10/20 mg, or ROSUV 20 mg for 16 weeks. All patients were assessed before and after treatment: primary outcomes were lipid peroxidation (LPO), and nitric oxide (NO) surrogate levels in plasma; secondary outcomes included NCS, neuropathic symptom scores, and metabolic parameters. Data were expressed as mean ± SD or SEM, frequencies, and percentages; we used nonparametric analysis.Results. LPO levels were reduced in both statin arms after 16 weeks of treatment (p<0.05versus baseline), without changes in the placebo group. NO levels were not significantly affected by statin treatment, although a trend towards significance concerning increased NO levels was noted in both statin arms. No significant changes were observed for the NCS or composite scores.Discussion. EZE/SIMV and ROSUV are superior to placebo in reducing LPO in subjects with T2DM suffering from polyneuropathy. This trial is registered withNCT02129231.
