Abstract Background Therapeutic targeting of host-cell factors required for SARS-CoV-2 entry is an alternative strategy to ameliorate COVID-19 severity. SARS-CoV-2 entry into lung epithelium requires the TMPRSS2 cell surface protease. Pre-clinical and correlative data in humans suggest that anti-androgenic therapies can reduce the expression of TMPRSS2 on lung epithelium. Accordingly, we hypothesize that therapeutic targeting of androgen receptor signaling via degarelix, a luteinizing hormone-releasing hormone (LHRH) antagonist, will suppress COVID-19 infection and ameliorate symptom severity. Methods This is a randomized phase 2, placebo-controlled, double-blind clinical trial in 198 patients to compare efficacy of degarelix plus best supportive care versus placebo plus best supportive care on improving the clinical outcomes of male Veterans who have been hospitalized due to COVID-19. Enrolled patients must have documented infection with SARS-CoV-2 based on a positive reverse transcriptase polymerase chain reaction result performed on a nasopharyngeal swab and have a severity of illness of level 3–5 (hospitalized but not requiring invasive mechanical ventilation). Patients stratified by age, history of hypertension, and severity are centrally randomized 2:1 (degarelix: placebo). The composite primary endpoint is mortality, ongoing need for hospitalization, or requirement for mechanical ventilation at 15 after randomization. Important secondary endpoints include time to clinical improvement, inpatient mortality, length of hospitalization, duration of mechanical ventilation, time to achieve a normal temperature, and the maximum severity of COVID-19 illness. Exploratory analyses aim to assess the association of cytokines, viral load, and various comorbidities with outcome. In addition, TMPRSS2 expression in target tissue and development of anti-viral antibodies will also be investigated. Discussion In this trial, we repurpose the FDA approved LHRH antagonist degarelix, commonly used for prostate cancer, to suppress TMPRSS2, a host cell surface protease required for SARS-CoV-2 cell entry. The objective is to determine if temporary androgen suppression with a single dose of degarelix improves the clinical outcomes of patients hospitalized due to COVID-19.

Gemcitabine And Cisplatin

TPS4162 Background: In a recently conducted study we have shown that combination of gemcitabine and oxaliplatin is superior to 5 fluorouracil and leucoverine or best supportive care. (Sharma A, Dwary AD, Mohanti BK,et al. Best supportive care compared with chemotherapy for unresectable gall bladder cancer:A randomized controlled study. J Clin Oncol. 2010; 28: 4581-4586.) In another recent publication from UK, gemcitabine and cisplatin combination was found superior to gemcitabine alone in biliary tract cancers (J W Valle, HS Wasan, DD Palmer, et al. Cisplatin plus gemcitabine versus gemcitabine for biliary tract cancer. N Eng J Med. 2010;362:1273-1281.).The current study is being planned to see whether the combination of gemcitabine and oxaliplatin is equivalent (equivalence study) to gemcitabine and cisplatin in these patients. Methods: Primary end point of the study is overall survival in subjects receiving mGEMOX or GemCis regimen. Secondary end points are: a) Comparison of progression free survival in 2 groups; b) Response rates in two groups; c) Identification of genes predictive of responses in a subset of patients; d) To evaluate role of PET CT in GBC patients predicting disease activity. Sample size was calculated taking median survival of 9.5 months in our previous study with mGEMOX and 11.7 months with GemCis. For this total of 216 patients are required (108 in each arm); to make for major protocol violation and lost to follow up additional 22 patients in each arm will be enrolled. Thus in total 260 patients (130) in each arm will be recruited. This will have alpha and beta values of 0.05 and 0.20 respectively. So far 103 patients have been enrolled and interim analysis is being planned. Treatment protocol: Cycles will be repeated every 3 weeks. Arm A- mGEMOX. Inj Oxaliplatin 80 mg/m22 hours infusion in Dextrose 5% Day 1 and 8. Inj Gemcitabine 900 mg/m2IV 30 minutes infusion day 1 and 8 maximum of 6 cycles. Arm B- GEMCIS. Inj Cisplatin 25 mg/m2PO Days 1 and 8. Inj Gemcitabine 1000 mg/m2IV 30 minutes infusion day1and 8 maximum of 8 cycles. Clinical trial information: CTRI/2010/091/001406.

Purpose We designed this study to evaluate efficacy of modified gemcitabine and oxaliplatin (mGEMOX) over best supportive care (BSC) or fluorouracil (FU) and folinic acid (FA) in unresectable gall bladder cancer (GBC). Patients and Methods Patients with unresectable GBC were enrolled for single center randomized study. Arm A, BSC; arm B, FU 425 mg/m2 and FA 20 mg/m2 intravenous (IV) bolus weekly for 30 weeks (FUFA); arm C, gemcitabine 900 mg/m2 and oxaliplatin 80 mg/m2 IV infusion on days 1 and 8 every 3 weeks for maximum of six cycles. Eighty-one patients were randomly assigned, arms A (n = 27), B (n = 28), and C (n = 26). Results Complete response plus partial response in the three groups was 0 (0%), four (14.3%), and eight (30.8%) respectively (P < .001). Two patients in the mGEMOX arm and one patient in the FUFA arm underwent curative resection after chemotherapy. One patient in the mGEMOX arm had complete pathologic response. Median overall survival (OS) was 4.5, 4.6, and 9.5 months for the BSC, FUFA, and mGEMOX arms (P = .039), respectively. Progression-free survival (PFS) was 2.8, 3.5, and 8.5 months for the three groups (P < .001). There was no difference in grade 3/4 toxicities in the chemotherapy arms except transaminitis, which was more prevalent in mGEMOX arm (P = .04). Two patients in the FUFA arm and 10 patients in the mGEMOX arm had grade 3 or 4 myelosuppression. Two patients in the mGEMOX group had neutropenic fever that resolved with antibiotics. Conclusion This randomized controlled trial confirmed the efficacy of chemotherapy (mGEMOX) compared with BSC and FUFA in improving OS and PFS in unresectable GBC.

PURPOSE: Patients with high-risk myelodysplastic syndrome (MDS) have high mortality from bone marrow failure or transformation to acute leukemia. Supportive care is standard therapy. We previously reported that azacitidine (Aza C) was active in patients with high-risk MDS.PATIENTS AND METHODS: A randomized controlled trial was undertaken in 191 patients with MDS to compare Aza C (75 mg/m2/d subcutaneously for 7 days every 28 days) with supportive care. MDS was defined by French-American-British criteria. New rigorous response criteria were applied. Both arms received transfusions and antibiotics as required. Patients in the supportive care arm whose disease worsened were permitted to cross over to Aza C.RESULTS: Responses occurred in 60% of patients on the Aza C arm (7% complete response, 16% partial response, 37% improved) compared with 5% (improved) receiving supportive care (P < .001). Median time to leukemic transformation or death was 21 months for Aza C versus 13 months for supportive care (P = .007). Transformation to acute myelogenous leukemia occurred as the first event in 15% of patients on the Aza C arm and in 38% receiving supportive care (P = .001). Eliminating the confounding effect of early cross-over to Aza C, a landmark analysis after 6 months showed median survival of an additional 18 months for Aza C and 11 months for supportive care (P = .03). Quality-of-life assessment found significant major advantages in physical function, symptoms, and psychological state for patients initially randomized to Aza C.CONCLUSION: Aza C treatment results in significantly higher response rates, improved quality of life, reduced risk of leukemic transformation, and improved survival compared with supportive care. Aza C provides a new treatment option that is superior to supportive care for patients with the MDS subtypes and specific entry criteria treated in this study.

Background: Antenatal care (ANC) in many low- and middle-income countries is under-utilized and of sub-optimal quality. Group ANC (G-ANC) is an intervention designed to improve the experience and provision of ANC for groups of women (cohorts) at similar stages of pregnancy. Methods: A two-arm, two-phase, cluster randomized controlled trial (cRCT) (non-blinded) is being conducted in Kenya and Nigeria. Public health facilities were matched and randomized to either standard individual ANC (control) or G-ANC (intervention) prior to enrollment. Participants include pregnant women attending first ANC at gestational age <24 weeks, health care providers, and sub-national health managers. Enrollment ended in June 2017 for both countries. In the intervention arm, pregnant women are assigned to cohorts at first ANC visit and receive subsequent care together during five meetings facilitated by a health care provider (Phase 1). After birth, the same cohorts meet four times over 12 months with their babies (Phase 2). Data collection was performed through surveys, clinical data extraction, focus group discussions, and in-depth interviews. Phase 1 data collection ended in January 2018 and Phase 2 concludes in November 2018. Intention-to-treat analysis will be used to evaluate primary outcomes for Phases 1 and 2: health facility delivery and use of a modern method of family planning at 12 months postpartum, respectively. Data analysis and reporting of results will be consistent with norms for cRCTs. General estimating equation models that account for clustering will be employed for primary outcome analyzes. Results: Overall 1,075 and 1,013 pregnant women were enrolled in Nigeria and Kenya, respectively. Final study results will be available in February 2019. Conclusions: This is the first cRCT on G-ANC in Africa. It is among the first to examine the effects of continuing group care through the first year postpartum.
