Abstract
RATIONALE Recurrence of hepatocellular carcinoma (HCC) after liver transplantation (LT) remains a major therapeutic challenge. In recent years, new molecular-targeted therapies, such as cabozantinib, have been approved for the treatment of advanced HCC. However, clinical experience with these new drugs in the treatment of HCC in the LT setting is very limited. PATIENT CONCERNS In 2003, a 36-year-old woman was referred to the hospital with right upper abdominal pain. DIAGNOSIS An initial ultrasound of the liver demonstrated a large unclear lesion of the left lobe of the liver. The magnet resonance imaging findings confirmed a multifocal inoperable HCC in a non-cirrhotic liver. Seven years after receiving a living donor LT, pulmonary and intra-hepatic recurrence of the HCC was radiologically diagnosed and histologically confirmed. INTERVENTIONS Following an interdisciplinary therapy concept consisting of surgical, interventional-radiological (with radiofrequency ablation [RFA]) as well as systemic treatment, the patient achieved a survival of more than 10 years after tumor recurrence. As systemic first line therapy with sorafenib was accompanied by grade 3 to 4 toxicities, such as mucositis, hand-foot skin reaction, diarrhea, liver dysfunction, and hyperthyroidism, it had to be discontinued. After switching to cabozantinib from June 2018 to April 2020, partial remission of all tumor manifestations was achieved. The treatment of the remaining liver metastasis could be completed by RFA. The therapy with cabozantinib was well tolerated, only mild arterial hypertension and grade 1 to 2 mucositis were observed. Liver transplant function was stable during the therapy, no drug interaction with immunosuppressive drugs was observed. OUTCOMES More than 10 years survival after recurrence of HCC after living-donor LT due to intensive multimodal therapy concepts, including surgery, RFA, and systemic therapy with cabozantinib in the second line therapy. LESSONS In conclusion, this report highlights the tolerability and effectiveness of cabozantinib for the treatment of HCC recurrence after LT. We show that our patient with a late recurrence of HCC after LT benefitted from intensive multimodal therapy concepts, including surgery, RFA, and systemic therapy.

Androgen-deprivation induced senescence in prostate cancer cells is permissive for the development of castration-resistance but susceptible to senolytic therapy. Biochem Pharmacol 2021; 193:114765. [PMID: 34536356 DOI: 10.1016/j.bcp.2021.114765] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 08/30/2021] [Accepted: 09/13/2021] [Indexed: 01/26/2023]
Abstract
Prostate cancer (PCa) is one of the leading causes of cancer-related deaths in men. Although androgen deprivation therapies (ADT) and antiandrogens confer increased survival rates, most patients eventually develop castration resistant disease (CRPC). Previous studies have shown that these treatments have limited cytotoxicity, and instead, promote tumor cell growth arrest. We show here that PCa cells grown in either charcoal-stripped serum or exposed to the antiandrogen, bicalutamide, undergo a senescent growth arrest marked by morphological changes, upregulated senescence-associated-β-galactosidase (SA-β-Gal), cathepsin D accumulation, and expression of the senescence-associated secretory phenotype (SASP). The senescent growth arrest is, however, transient, as cells can resume proliferation upon restoration of normo-androgenic conditions. Intriguingly, enrichment for senescent cells confirmed that ADT-induced senescent cells recover their proliferative capacity, even under prolonged androgen deprivation, and form androgen-independent outgrowths. Transplantation of the enriched senescent population into castrated, syngeneic mice confirmed that senescent cells escape the growth arrest and form castration-resistant tumors in vivo. Outgrowth from senescence was associated with increased expression of constitutively active androgen receptor splice variants, a common mechanism of resistance to ADT. Finally, the selective elimination of senescent PCa cells following ADT in vitro by the senolytic navitoclax (ABT-263) interfered with the development of androgen-independent outgrowth. Taken together, these data support the premise that ADT-induced senescence is a transient cell state from which CRPC populations can emerge, identifying senescence as a potential driver of disease progression. Furthermore, it is feasible that senolytic therapy to eliminate senescent PCa cells could delay disease recurrence and/or progression to androgen independence.

Abstract
The term “cachexia” is derived from the Greek words kakos (bad) and hexis (habit). Cachexia is a malnutrition associated with chronic diseases such as cancer, chronic heart failure, chronic renal failure, and autoimmune diseases, and is characterized by decreased skeletal muscle mass. Cancer cachexia is quite common in patients with advanced cancer. Weight loss is also a characteristic symptom of cancer cachexia, along with decreased skeletal muscle mass. As nutritional supplementation alone cannot improve cachexia, cytokines and tumor-derived substances have been attracting attention as its relevant factors. Cancer cachexia can be also associated with reduced chemotherapeutic effects, increased side effects and treatment interruptions, and even poorer survival. In 2011, a consensus definition of cachexia has been proposed, and the number of relevant research reports has increased significantly. However, the pathogenesis of cachexia is not fully understood, and there are currently few regulatory-approved standard treatments for cachexia. The main reason for this is that multiple etiologies are involved in the development of cachexia. In this review, we will outline the current status of cachexia, the mechanisms of which have been elucidated in recent years, especially from the perspective of advanced cancer.

Abstract
ABSTRACT Patient was a 73-year-old woman with metastatic renal cell carcinoma. Bone scan showed multifocal bone metastases. The patient received cabozantinib treatment for more than 1 year. On the follow-up bone scan, the previously biopsy-proven left pelvic bone lesion has improved, whereas the right maxillary lesion showed increased extent and intensity of abnormal radiotracer uptake. Given the different change pattern of these lesions, the right maxillary lesion was further evaluated. Biopsy results confirmed devitalized bone with bacterial colonies overgrowth and without tumor cell, suggestive of medication-related osteonecrosis.

Abstract
Acute lung injury (ALI) afflicts approximately 200,000 patients annually and has a 40% mortality rate. The COVID-19 pandemic has massively increased the rate of ALI incidence. The pathogenesis of ALI involves tissue damage from invading microbes and, in severe cases, the overexpression of inflammatory cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). This study aimed to develop a therapy to normalize the excess production of inflammatory cytokines and promote tissue repair in the lipopolysaccharide (LPS)-induced ALI. Based on our previous studies, we tested the insulin-like growth factor I (IGF-I) and BTP-2 therapies. IGF-I was selected, because we and others have shown that elevated inflammatory cytokines suppress the expression of growth hormone receptors in the liver, leading to a decrease in the circulating IGF-I. IGF-I is a growth factor that increases vascular protection, enhances tissue repair, and decreases pro-inflammatory cytokines. It is also required to produce anti-inflammatory 1,25-dihydroxyvitamin D. BTP-2, an inhibitor of cytosolic calcium, was used to suppress the LPS-induced increase in cytosolic calcium, which otherwise leads to an increase in proinflammatory cytokines. We showed that LPS increased the expression of the primary inflammatory mediators such as toll like receptor-4 (TLR-4), IL-1β, interleukin-17 (IL-17), TNF-α, and interferon-γ (IFN-γ), which were normalized by the IGF-I + BTP-2 dual therapy in the lungs, along with improved vascular gene expression markers. The histologic lung injury score was markedly elevated by LPS and reduced to normal by the combination therapy. In conclusion, the LPS-induced increases in inflammatory cytokines, vascular injuries, and lung injuries were all improved by IGF-I + BTP-2 combination therapy.

Abstract
BACKGROUND Cabozantinib is an effective treatment for metastatic renal cell carcinoma (mRCC). The international mRCC database consortium (IMDC) criteria is the gold standard for risk stratification in mRCC. We created a risk scoring system specific for mRCC patients treated with cabozantinib. METHODS We conducted a retrospective review of 87 patients with mRCC treated with cabozantinib at Winship Cancer Institute from 2015 to 2019. Overall survival (OS) and progression free survival (PFS) were used to measure clinical outcomes. Upon variable selection in multivariable analysis (MVA), elevated baseline monocyte-to-lymphocyte ratio (MLR), sarcomatoid histologic component, ECOG PS > 1, and absence of bone metastases were each assigned 1 point. A three-group risk scoring system was then created: low (score=0-1), intermediate (score=2), and high risk (score=3-4). The Cox proportional hazard model and Kaplan-Meier method were used for survival analyses. RESULTS The median age was 62 years-old and the majority were males (71%) with clear-cell RCC (75%). Most (67%) received at least 1 prior line of systemic therapy. High risk and intermediate risk pts had significantly shorter OS (high risk HR: 13.84, p<0.001; intermediate risk HR: 3.50, p = 0.004) and PFS (high risk HR: 7.31, p<0.001; intermediate risk HR: 1.87, p = 0.053) compared to low risk patients in MVA. CONCLUSIONS RCC patients treated with cabozantinib may benefit from specific risk stratification criteria using RCC histology, ECOG PS, sites of metastatic disease, and MLR. These variables are easily accessible in the clinical setting and may be helpful to determine which mRCC patients may benefit from treatment with cabozantinib.

Abstract
Introduction Scant evidence reveals whether the use of weekly versus daily pain ratings leads to meaningful differences when measuring pain as a clinical trial outcome. We compared the ability of weekly ratings and descriptors of daily ratings to evaluate pain as an endpoint in a randomized phase 3 drug trial. Methods Participants (n = 119) with metastatic castration-resistant prostate cancer were randomized to treatment arms and rated their pain on the average and at its worst during a baseline week and at weeks 3, 6, and 12 of study treatment. For each reporting period, participants rated their pain daily for 7 days. On day 7, participants rated their pain over the prior 7 days. We estimated mean differences and intraclass correlation coefficients of the weekly ratings and the mean and the maximum daily ratings. We compared the ability of the weekly ratings and the daily rating descriptors to detect change in pain and evaluated the agreement of the weekly rating and the mean daily rating of pain at its worst to detect treatment response. Results For both pain constructs, the weekly rating was consistently higher than the mean daily rating and lower than the maximum daily rating yet was moderately to highly correlated with both daily rating descriptors (intraclass correlation coefficient range = 0.55–0.94). The weekly rating and the daily rating descriptors consistently detected change in pain for the study sample and participant subgroups. Substantial agreement existed between the weekly rating and the mean daily rating of pain at its worst when used with trial protocol opioid criteria to detect treatment response (Cohen’s κ = 0.71). Conclusion Use of daily over weekly ratings delivered no added benefit in evaluating pain in this clinical trial. This study is the first to compare weekly and daily recall to measure pain as an endpoint in a randomized phase 3 drug trial, and the pattern of differences in ratings that we observed is consistent with other recent evaluations of weekly and daily symptom reporting.

Abstract
BACKGROUND Overexpression of certain long non-coding RNAs (lncRNAs) promotes the progression of castration-resistant prostate cancer (CRPC). The significance and potential role of the lncRNA designated pituitary tumour-transforming 3, pseudogene (PTTG3P) in CRPC is unknown. METHODS We detected PTTG3P expression by qPCR. Upregulated PTTG3P expression was performed to explore the role of PTTG3P in PCa cells resistant to ADT (androgen deprivation therapy). The relationship among PTTG3P, mir-146a-3p and PTTG1 were validated by qPCR, western blot and luciferase assay. RESULTS PTTG3P levels were significantly increased in the androgen-independent PC cell lines, as well as in CRPC tissues compared with those of the androgen-dependent prostate cancer cell line LNCaP and tumour tissues of patients with hormone-naive prostate cancers. Enforced expression of PTTG3P in androgen-deprived LNCaP cells significantly enhanced survival, clonogenicity, and tumorigenicity. Further, PTTG3P acted as a competing endogenous RNA (ceRNA, natural miRNA sponge) to upregulate PTTG1 expression by competing for mir-146a-3p in the progression to CRPC. CONCLUSION Our findings suggest that PTTG3P promotes the resistance of prostate cancer cells to androgen-deprivation therapy via upregulating PTTG1. PTTG3P may therefore represent a potential target for therapy of CRPC.

Abstract
BACKGROUND Recently, three published phase III trials highlighted the superiority of investigational drugs compared to placebo, thus leading to their approval in the second-line setting. We report here a MAIC of second-line MKI options for patients with HCC previously treated with sorafenib using individual real-world data of regorafenib and aggregate data of second-line cabozantinib from the CELESTIAL trial. METHODS Data from 278 patients who received regorafenib as second-line therapy after sorafenib failure for unresectable HCC were used as IPD. Data inclusion were adapted to those reported in the CELESTIAL trial in the subset of patients who received sorafenib as the only prior therapy. Survival medians and rates were obtained from Kaplan-Meier curves, and differences between regorafenib and cabozantinib groups were explored through Cox regression adjusted for weights originating from MAIC. RESULTS The median OS of the weighted regorafenib group was 11.1 months (IQR: 5.6-16.4) and 11.3 (IQR: 6.7-22.4) for cabozantinib; HR 0.83 (95%CI 0.62-1.09). The median PFS of the weighted regorafenib group was 3.0 months (IQR: 1.9-4.8) and 5.5 (IQR: 2.3-9.3) for cabozantinib; HR 0.50 (95%CI 0.41-0.62). In the subgroup who received prior sorafenib for < 3 months, the median OS of the regorafenib group was 6.5 months (IQR: 4.7-10.9) and 9.5 months (IQR: 5.9-18.2) for cabozantinib; HR 0.68 (95%CI 0.39-1.16). In the subgroup receiving prior sorafenib for 3 to < 6 months, the median OS of the regorafenib group was 8.0 months (IQR: 4.2-15.2) and 11.5 (IQR: 6.5-23.9) for cabozantinib; HR 0.66 (95%CI 0.42-1.02). In the subgroup receiving prior sorafenib for ≥ 6 months, the median OS of the regorafenib group was 13.4 (IQR: 8.1-46.5) and 12.3 (IQR: 6.6-22.9) for cabozantinib; HR 0.89 (95%CI 0.52-1.51). CONCLUSION Our results confirmed no differences between regorafenib and cabozantinib in terms of OS. However, in earlier progressors on prior sorafenib a larger benefit might be expected from cabozantinib treatment.

Abstract
BACKGROUND AND AIMS The 12-week regimen of ombitasvir/paritaprevir/ritonavir and dasabuvir (OPrD) has shown high efficacy and tolerability in clinical trials for the treatment of chronic hepatitis C virus (HCV). The shorter 8-week regimen has been recently incorporated into clinical guidelines and on-label indications, but real-world evidence on its use is limited. Given this knowledge gap, the AMETHYST study aimed to evaluate the effectiveness of the 8- and 12-week regimens of OPrD in treatment-naive patients with HCV with mild to moderate liver fibrosis in Romanian clinical practice. METHODS This was a secondary data collection study analyzing data from a 1-year Patient Support Program in HCV in Romania. Patients received OPrD treatment for 8 or 12 weeks. The effectiveness endpoint was sustained virologic response 12 weeks post-treatment (SVR12). RESULTS A total of 1,835 treatment-naive patients with HCV with mild or moderate fibrosis were included in the study. Of these, 426 and 1,375 completed the 8-week and 12-week regimens, respectively. SVR12 was 98.1% in the 8-week treatment group and 98.7% in the 12-week treatment group. CONCLUSION The study provides real-world evidence that 8-week and 12-week treatment regimens of OPrD are highly effective in treatment-naive patients with HCV with mild to moderate liver fibrosis.

Abstract
Background: Management of patients with advanced medullary thyroid cancer (MTC) remains a therapeutic challenge. The multi-tyrosine kinase inhibitors (TKIs) vandetanib and cabozantinib have been approved for the treatment of progressive MTC based on prolonged progression-free survival (PFS) in phase 3 clinical trials. Patients and Methods: To evaluate clinical characteristics, treatment regimens, efficacy, and treatment emergent adverse events (TEAEs) of vandetanib and cabozantinib in MTC patients outside clinical trials at four German tertiary care centers. Forty-eight patients diagnosed between 1990 and 2018 were included. PFS and overall survival (OS) probabilities were estimated using the Kaplan-Meier method and compared by log-rank test. Results: The median age at diagnosis was 46 years (15-80 years); a germ line RET (rearranged during transfection) mutation was known in 6 (13%) patients. Thirty-two (67%) patients showed progressive disease before TKI initiation. Forty-seven (98%) patients were treated with vandetanib and 23 (48%) patients with cabozantinib. Vandetanib was first-line treatment in 41 (85%) patients and cabozantinib in 7 (15%) patients. Partial response was the best response in 12 (26%) patients treated with vandetanib and in 5 (22%) patients treated with cabozantinib. Sixteen (34%) patients treated with vandetanib and 3 (13%) patients treated with cabozantinib had stable disease ≥24 weeks. The median PFS for vandetanib and cabozantinib was 17 months [95% confidence interval, CI, 9.3-24.6 months] and 4 months [CI 3.1-4.9 months], respectively. The 6- and 12-month survival rates were 98% and 86% for vandetanib and 78% and 70% for cabozantinib, respectively. The median OS for vandetanib and cabozantinib was 53 months [CI 43.7-62.3 months] and 24 months [CI 5.9-42.1 months], respectively. In vandetanib-treated patients, the PFS and OS were significantly longer in patients aged ≤60 years at TKI initiation and in patients with ≥5 TEAEs. Additionally, the PFS was longer in the absence of bone metastases. In cabozantinib-treated patients, the PFS was significantly longer in patients experiencing TEAEs and in patients aged ≤60 years, and the OS was significantly longer in patients who had TEAEs and in patients with ≥5 TEAEs. Conclusions: Vandetanib and cabozantinib are effective treatment options in the majority of MTC patients. We hypothesize that the poorer prognosis of cabozantinib-treated patients in our retrospective analysis is most likely due to its use as second-line treatment after treatment failure on vandetanib. However, different degrees of efficacy of the two drugs are possible.

Abstract
BACKGROUND Systemic therapy for hepatocellular carcinoma (HCC) consisting of the tyrosine kinase inhibitor sorafenib has remained unchanged for over a decade, although results from phase III targeted therapy trials have recently emerged. This review considers available phase III evidence on the use and sequencing of targeted therapy for intermediate and advanced non-locoregional therapy (LRT) eligible HCC and discusses implications for clinical practice. METHODS Published and presented literature on phase III data reporting on targeted therapy for advanced HCC that was not eligible for loco-regional therapies was identified using the key search terms "hepatocellular cancer" AND "advanced" AND "targeted therapy" AND "phase III" OR respective aliases (PRISMA). RESULTS Ten phase III trials assessed targeted therapy first-line and eight following sorafenib. In the first-line, atezolizumab plus bevacizumab statistically significantly improved overall survival (OS) and patient-reported outcomes (PROs) compared with sorafenib, while lenvatinib demonstrated non-inferior OS. Following progression on sorafenib, statistically significant OS improvements over placebo were seen for cabozantinib and regorafenib in unselected patients and for ramucirumab in those with baseline α-fetoprotein≥400 ng/mL. Based on improved OS and PROs, atezolizumab plus bevacizumab appears to be a preferred first-line treatment option for intermediate or advanced non-LRT eligible HCC. Phase III data informing sequencing of later lines of treatment is lacking. Therefore, sequencing principles are proposed that can be used to guide treatment selection. CONCLUSIONS Ongoing trials will continue to inform optimal therapy. Multiple targeted therapies have improved OS in intermediate or advanced non-LRT eligible HCC, although optimal sequencing is an area of ongoing investigation.

Abstract
We report a nanoparticle formulation of the SHH-pathway inhibitor vismodegib that improves efficacy for medulloblastoma, while reducing toxicity. Limited blood-brain barrier (BBB) penetration and dose-limiting extitle/citraneural toxicities complicate systemic therapies for brain tumors. Vismodegib is FDA-approved for SHH-driven basal cell carcinoma, but implementation for medulloblastoma has been limited by inadequate efficacy and excessive bone toxicity. To address these issues through optimized drug delivery, we formulated vismodegib in polyoxazoline block copolymer micelles (POx-vismo). We then evaluated POx-vismo in transgenic mice that develop SHH-driven medulloblastomas with native vasculature and tumor microenvironment. POx-vismo improved CNS pharmacokinetics and reduced bone toxicity. Mechanistically, the nanoparticle carrier did not enter the CNS, and acted within the vascular compartment to improve drug delivery. Unlike conventional vismodegib, POx-vismo extended survival in medulloblastoma-bearing mice. Our results show the broad potential for non-targeted nanoparticle formulation to improve systemic brain tumor therapy, and specifically to improve vismodegib therapy for SHH-driven cancers.

Abstract
IMPORTANCE Black patients have been underrepresented in prospective clinical trials of advanced prostate cancer. This study evaluated the efficacy of enzalutamide compared with bicalutamide, with planned subset analysis of Black patients with metastatic hormone-sensitive prostate cancer (mHSPC), which is a disease state responsive to androgen deprivation therapy (ADT). OBJECTIVE To compare the efficacy of enzalutamide vs bicalutamide in combination with ADT in men with mHSPC, with a subset analysis of Black patients. DESIGN, SETTING, AND PARTICIPANTS In this randomized clinical trial, a phase 2 screening design enabled a nondefinitive comparison of the primary outcome by treatment. Patients were stratified by race (Black or other) and bone pain (present or absent). Accrual of at least 30% Black patients was required. This multicenter trial was conducted at 4 centers in the US. Men with mHSPC with no history of seizures and adequate marrow, renal, and liver function were eligible. Data analysis was performed from February 2019 to March 2020. INTERVENTIONS Participants were randomized 1:1 to receive oral enzalutamide (160 mg daily) or bicalutamide (50 mg daily) in addition to ADT. MAIN OUTCOMES AND MEASURES The primary end point was the 7-month prostate-specific antigen (PSA) response (SMPR) rate, a previously accepted surrogate for overall survival (OS) outcome. Secondary end points included adverse reactions, time to PSA progression, and OS. RESULTS A total of 71 men (median [range] age, 65 [51-86] years) were enrolled; 29 (41%) were Black, 41 (58%) were White, and 1 (1%) was Asian. Thirty-six patients were randomized to receive enzalutamide, and 35 were randomized to receive bicalutamide. Twenty-six patients (37%) had bone pain and 37 patients (52%) had extensive disease. SMPR was achieved in 30 of 32 patients (94%; 95% CI, 80%-98%) taking enzalutamide and 17 of 26 patients (65%; 95% CI, 46%-81%) taking bicalutamide (P = .008) (difference, 29%; 95% CI, 5%-50%). Among Black patients, the SMPR was 93% (95% CI, 69%-99%) among those taking enzalutamide and 42% (95% CI, 19%-68%) among those taking bicalutamide (P = .009); among non-Black patients, the SMPR was 94% (95% CI, 74%-99%) among those taking enzalutamide and 86% (95% CI, 60%-96%) among those taking bicalutamide. The 12-month PSA response rates were 84% with enzalutamide and 34% with bicalutamide. CONCLUSIONS AND RELEVANCE The findings of this randomized clinical trial comparing enzalutamide with bicalutamide suggest that enzalutamide is associated with improved outcomes compared with bicalutamide, in terms of the rate and duration of PSA response, in Black patients with mHSPC. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02058706.

Abstract
BACKGROUND Current standard treatments for patients with metastatic renal cell carcinoma (mRCC) involve tyrosine kinase inhibitors (TKI) that inhibit angiogenesis. Cabozantinib is a multi TKI used for the treatment of mRCC in the first- and second-line setting. PURPOSE The aim of this study was the final analysis of treatment outcomes in patients with metastatic renal cell carcinoma (mRCC) treated with cabozantinib after previous targeted therapy. PATIENTS AND METHODS A total of 54 patients with mRCC from four oncology centers in the Czech Republic were evaluated retrospectively; the median follow-up was 18.5 months. Cabozantinib was administered in a dose of 60mg/day, a subset of patients received an initial dose of 40mg/day. The treatment was administered until the progression. The Kaplan-Meier analysis was used to calculate progression free survival (PFS) and overall survival (OS). We performed a multivariate analysis of risk factors for treatment outcomes (PFS, OS) by regression analysis. All statistics were evaluated at the significance level α = 0.05. RESULTS The median PFS in all patients was 9.3 months (95% CI 7.2 - 11.4). The median OS in all patients was 21.9 months (95% CI 15.5 - 28.4). The median PFS in patients with bone metastases was not statistically significantly different compared with patients without bone metastases (9.3 vs 8.7 months, P = 0.53). The median OS in patients with bone metastases was statistically significantly shorter compared with patients without bone metastases (17.7 vs 26.8 months, P = 0.021). A treatment response was observed in 40.7 % of cases, including one complete remission. The regression analysis demonstrated a significant effect on OS in patients with the presence of subsequent treatment (P = 0.001), patients with treatment duration of first line therapy 6 months (P = 0.019) and 12 months (P = 0.003) and in patients without bone metastases (P = 0.021). CONCLUSION Our final analysis of patients with mRCC treated with cabozantinib after previous targeted therapy confirmed its effectiveness.

Abstract
Hepatitis C virus (HCV) infections are more common among US veterans receiving care through Veterans Affairs (VA) Medical Centers than among the general population. Historically, HCV therapies had lower efficacy rates in VA patients, possibly due to common comorbidities such as psychiatric disorders and substance abuse. The direct-acting antivirals ombitasvir/paritaprevir/ritonavir and dasabuvir (OBV/PTV/r+DSV)±ribavirin (RBV) are approved in the US for HCV genotype 1 (GT1)-infected adults with or without cirrhosis. This study prospectively evaluated the safety and efficacy of OBV/PTV/r+DSV±RBV in VA patients with HCV GT1 infection. TOPAZ-VA was a phase 3b, open-label trial. Adult US veterans with HCV GT1 infection, without cirrhosis or with compensated cirrhosis, were eligible for enrollment. Patients with GT1a infection received OBV/PTV/r +DSV+RBV for 12 weeks or 24 weeks (for those with cirrhosis); GT1b-infected patients without cirrhosis received OBV/PTV/r +DSV for 12 weeks; those with cirrhosis received OBV/PTV/r +DSV with RBV. The primary endpoint was sustained virologic response at posttreatment week 12 (SVR12); safety was also assessed. Ninety-nine patients were enrolled at 10 sites from May through November 2015. The majority were male (96%), white (60%), and with GT1a infection (68%); 49% reported ongoing psychiatric disorders. Overall, 94% (93/99) achieved SVR12; three patients had a virologic failure. The most common AEs were fatigue (28%), headache (20%), and nausea (15%); six patients discontinued treatment due to AEs. In US veterans with HCV GT1 infection, OBV/PTV/r +DSV±RBV yielded a 94% overall SVR12 rate and was well tolerated. The presence of psychiatric disorders and/or injection drug use did not impact efficacy.

Abstract
BACKGROUND Hepatic decompensation is a fatal on-treatment side effect during chronic hepatitis C treatment with paritaprevir/ritonavir/ombitasvir and dasabuvir (PrOD). Prompt bilirubin testing can reveal hepatic failure in susceptible patients, and clinical parameters precipitating early elevation of bilirubin can warn clinicians to avoid PrOD prescription. METHODS This retrospective study included 169 Hepatitis C virus (HCV)-genotype 1b patients who underwent a 12-week course of PrOD with or without ribavirin. Laboratory data underwent χ analysis with Fisher's exact test to determine the precipitating factors causing hyperbilirubinemia in patients who had received 1 week of treatment. RESULTS Sustained viral response was achieved in 164 patients (97.0%). Total bilirubin was ≥2 mg/dL (21.3%) in 36 patients after 1 week of treatment. Pretreatment white blood cell (WBC) <4500/µL and platelet <100,000/µL correlated with total bilirubin ≥2 mg/dL (relative risk [RR]: 21.64, 95% CI: 5.23-89.64, p < 0.001) after 1 week of treatment. Pretreatment platelet ≥100 000/µL and WBC <4500/µL correlated with direct bilirubin ≥0.45 mg/dL (RR: 6.56, 95% CI: 1.42-30.38, p = 0.016) and indirect bilirubin ≥0.6 mg/dL (RR: 4.77, 95% CI: 1.03-22.15, p = 0.046). Pretreatment platelet <100,000/µL with F3/F4 fibrosis correlated with first week total bilirubin ≥2 mg/dL (RR: 3.57, 95% CI: 1.35-9.09, p = 0.010). CONCLUSION PrOD is an effective antiviral regimen for HCV genotype 1b patients. Total bilirubin ≥2 mg/dL after 1 week of treatment serves as an early warning of irreversible progression toward hepatic decompensation, and the current study provides a guide by which to monitor chronic hepatitis C patients undergoing PrOD treatment.

Abstract
Enobosarm (ostarine, MK-2866, or GTx-024) is a non-steroidal selective androgen receptor modulator. This study evaluated the effect of various regimens of enobosarm (EN) on bone healing in an orchiectomized rat model for aged male osteoporosis and compared it to testosterone (T) treatment. Ninety eight-month-old male Sprague Dawley rats were either orchiectomized (Orx) or left intact (Non-Orx) and divided into groups (n = 15/group): (1) Non-Orx; (2) Orx; (3) Orx+T-th; (4) Orx+EN-th; (5) Orx+T-pr; and (6) Orx+EN-pr. Prophylaxis (Pr) treatments were applied immediately after Orx for up to 18 weeks. Therapy (Th) treatments were applied 12 weeks after Orx for up to 6 weeks. Bilateral tibia osteotomy with plate osteosynthesis was performed 12 weeks after Orx in all groups. EN and T were mixed with the diet; the daily dosage was 0.35 ± 0.06 and 41 ± 8 mg/kg BW, respectively. Both T treatments improved bone healing by increasing callus volume and area, bone volume and density, and cortical width; they had no effect on prostate or levator ani weight. EN-pr increased the callus area and callus density and decreased cortical density, but increased prostate weight. The effect of T-pr and T-th on bone was stronger than EN-pr. EN-th affected bone healing negatively by reducing callus density and area and delaying osteotomy bridging. Levator ani weight was increased in both EN groups. EN treatment after fracture is not advisable in aged males. EN-pr treatment as a therapy for bone healing in men could be further investigated; endocrinological side effects must be closely monitored.

Abstract
Importance A high incidence of fall and fracture in a subset of patients treated with androgen receptor inhibitors (ARIs) has been reported, although the relative risk (RR) of fall and fracture for patients who receive ARI treatment is unknown. Objective To evaluate whether treatment with ARIs is associated with an elevated relative risk for fall and fracture in patients with prostate cancer. Data Sources Cochrane, Scopus, and MedlinePlus databases were searched from inception through August 2019. Study Selection Randomized clinical trials comparing patients with prostate cancer treated with any ARI or placebo were included. Data Extraction and Synthesis Two independent reviewers used a standardized data extraction and quality assessment form. A mixed effects model was used to estimate the effects of ARI on relative risk, with included studies treated as random effects and study groups treated as fixed effects in the pooled analysis. Sample size for each study was used to weight the mixed model. Statistical analysis was performed from August to October 2019. Main Outcomes and Measures The primary outcome was RR of fall and fractures for patients receiving ARI treatment. Results Eleven studies met this study's inclusion criteria. The total population was 11 382 men (median [range] age: 72 [43-97] years), with 6536 in the ARI group and 4846 in the control group. Participants in the ARI group could have received enzalutamide, apalutamide, or darolutamide in combination with androgen deprivation therapy or other enzalutamide combinations; patients in the control group could have received placebo, bicalutamide, or abiraterone. The reported incidence of fall was 525 falls (8%) in the ARI group and 221 falls (5%) in the control group. The incidence of fracture was 242 fractures (4%) in the ARI group and 107 fractures (2%) in the control group. Use of an ARI was associated with an increased risk of falls and fractures: all-grade falls (RR, 1.8; 95% CI, 1.42-2.24; P < .001); grade 3 or greater fall (RR, 1.6; 95% CI, 1.27-2.08; P < .001); all-grade fracture (RR, 1.59; 95% CI, 1.35-1.89; P < .001), and likely grade 3 or greater fracture (RR, 1.71; 95% CI, 1.12-2.63; P = .01). Conclusions and Relevance Use of ARI was associated with an increase in falls and fractures in patients with prostate cancer as assessed by a retrospective systematic review and meta-analysis. Further studies are warranted to identify and understand potential mechanisms and develop strategies to decrease falls and fractures associated with ARI use.

Abstract
Treatment of hepatitis C virus (HCV) infection in patients with chronic kidney disease was difficult in the past because of the use of interferon (IFN). It was associated with high risk IFN-related adverse reactions due to reduced renal clearance of IFN. This study aimed to evaluate the antiviral efficacy, safety, and tolerability of ombitasvir/paritaprevir/ritonavir/ribavirin in chronic kidney disease patients infected with chronic HCV.This observational, open-label prospective study was carried out on 103 patients infected chronic HCV with different grades of renal impairment. Paritaprevir/ritonavir and ombitasvir (75/50/12.5 mg) twice daily plus ribavirin were given to the patients for 12 weeks. Dose adjustment of ribavirin was done according to degree of renal impairment.Sustained virological response (12 weeks after the end of treatment) occurred in 101 patients (98.1%). Anemia occurred in 48 patients. No serious adverse events were observed in any patient.Paritaprevir/ritonavir and ombitasvir plus ribavirin for 12 weeks was considered to be safe and effective in the treatment of chronic HCV infected patients with varying degrees of renal impairment.
