Abstract
BACKGROUND The phase III KEYNOTE-604 study confirmed the benefit of pembrolizumab combined with chemotherapy in the first-line treatment of extensive-stage small-cell lung cancer (ES-SCLC). Taken into account the clinical benefits of pembrolizumab and its high cost, this study aimed to assess the cost-effectiveness of adding pembrolizumab to standard first-line etoposide-platinum (EP) for patients with ES-SCLC from the US payer perspective. METHODS A Markov model was developed to compare the cost and quality-adjusted life-year (QALY) of pembrolizumab plus EP and placebo plus EP over a 10-year time horizon. Clinical efficacy and safety data were pooled from the KEYNOTE-604 trial. Utilities were obtained from published resources. Costs were mainly collected from Medicare in 2020. Sensitivity analyses were performed to examine the robustness of our model. RESULTS Adding pembrolizumab to standard first-line EP resulted in the better effectiveness than EP chemotherapy alone for ES-SCLC by 0.22 QALYs. Pembrolizumab plus EP was dominated economically by placebo plus EP, leading to an incremental cost-effectiveness ratio (ICER) of $334,373/ QALY. Deterministic sensitivity analyses indicated that the uncertainty in model parameters exerted no substantial effect on our results. Probability sensitivity analysis indicated that probabilities for pembrolizumab plus EP being cost-effective within a wide range of willingness to pay were modest. CONCLUSION From the US payer perspective, the first-line treatment for ES-SCLC with pembrolizumab plus EP was not cost-effective compared with placebo plus EP. Although pembrolizumab combination chemotherapy was beneficial to the survival of ES-SCLC, price reduction may be the necessary to improve its cost-effectiveness.

Abstract
OBJECTIVES IRX-2 is a primary-cell-derived immune-restorative consisting of multiple human cytokines that act to overcome tumor-mediated immunosuppression and provide an in vivo tumor vaccination to increase tumor infiltrating lymphocytes (TILs). A randomized phase II trial was conducted of the IRX regimen 3 weeks prior to surgery consisting of an initial dose of cyclophosphamide followed by 10 days of regional perilymphatic IRX-2 cytokine injections and daily oral indomethacin, zinc and omeprazole (Regimen 1) compared to the identical regimen without IRX-2 cytokines (Regimen 2). METHODS A total of 96 patients with previously untreated, stage II-IV oral cavity SCC were randomized 2:1 to experimental (1) or control (2) regimens (64:32). Paired biopsy and resection specimens from 62 patients were available for creation of tissue microarray (n = 39), and multiplex immunohistology (n = 54). Increases in CD8+ TIL infiltrate scores of at least 10 cells/mm2 were used to characterize immune responders (IR). RESULTS Regimen 1 was associated with significant increases in CD8+ infiltrates (p = 0.01) compared to Regimen 2. In p16 negative cancers (n = 26), significant increases in CD8+ and overall TILs were evident in Regimen 1 (p = 0.004, and 0.04 respectively). IRs were more frequent in Regimen 1 (74% vs 31%, p = 0.01). Multiplex immunohistology for PD-L1 expression confirmed an increase in PD-L1 H score for Regimen 1 compared to Regimen 2 (p = 0.11). CONCLUSIONS The findings demonstrate significant increases in TILs after perilymphatic IRX-2 injections. Three quarters of patients showed significant immune responses to IRX-2. (NCT02609386).

Abstract
INTRODUCTION There is increasing evidence demonstrating the benefits of exercise in counteracting cancer treatment-related fatigue. Immunotherapy is an established treatment for advanced melanoma, and is associated with fatigue in a third of patients. The safety and efficacy of exercise in counteracting treatment-related fatigue in patients with advanced melanoma receiving immunotherapy are yet to be determined. This study aims to assess the safety, adherence to and acceptability of a mixed-methods parallel-group, pilot randomised controlled trial of a personalised, 12-week semi-supervised exercise programme prescribed by an exercise physiologist (iMove) in 30 patients with stage IV melanoma scheduled to commence immunotherapy: single agent ipilimumab, nivolumab or pembrolizumab, or combination ipilimumab and nivolumab. The trial will be used to provide preliminary evidence of the potential efficacy of exercise for managing fatigue. METHODS AND ANALYSIS Thirty participants will be recruited from a specialist cancer centre between May and September, 2019. Participants will be randomised 1:1 to receive iMove, or usual care (an information booklet about exercise for people with cancer). Feasibility data comprise: eligibility; recruitment and retention rates; adherence to and acceptability of exercise consultations, personalised exercise programme and study measures; and exercise-related adverse events. Patient-reported outcome measures assess potential impact of the exercise intervention on: fatigue, role functioning, symptoms and quality of life. Follow-up will comprise five time points over 24 weeks. Physical assessments measure physical fitness and functioning. ETHICS AND DISSEMINATION This study was reviewed and approved by the Peter MacCallum Cancer Centre Human Research Ethics Committee (HREC/48927/PMCC-2019). The findings from this trial will be disseminated via conference presentations and publications in peer-reviewed journals, and by engagement with clinicians, media, government and consumers. In particular, we will promote the outcomes of this work among the oncology community should this pilot indicate benefit for patients. TRIAL REGISTRATION NUMBER ACTRN12619000952145; Pre-results.

Abstract
BACKGROUND Topical calcipotriol plus 5-fluorouracil (5-FU) combination is an effective immunotherapy against actinic keratosis (AK), which is a precursor to squamous cell carcinoma (SCC). However, the long-term effectiveness of calcipotriol plus 5-FU treatment for SCC prevention is unknown. METHODS We performed a blinded prospective cohort study on participants of a randomized double-blind clinical trial in which a 4-day course of topical calcipotriol plus 5-FU combination was compared to Vaseline plus 5-FU (control) for AK treatment. SCC and basal cell carcinoma (BCC) incidences were assessed at 1, 2, and 3 years after trial. Tissues were analyzed for calcipotriol plus 5-FU-induced T cell immunity in the skin. RESULTS Calcipotriol plus 5-FU-induced tissue-resident memory T (Trm) cell formation in face and scalp skin associated with significantly higher erythema scores compared with control (P < 0.01). Importantly, more participants in the test cohort remained SCC-free over the more than 1,500-day follow-up period (P = 0.0765), and significantly fewer developed SCC on the treated face and scalp within 3 years (2 of 30 [7%] versus 11 of 40 [28%] in control group, hazard ratio 0.215 [95% CI: 0.048-0.972], P = 0.032). Accordingly, significantly more epidermal Trm cells persisted in the calcipotriol plus 5-FU-treated face and scalp skin compared with control (P = 0.0028). There was no significant difference in BCC incidence between the treatment groups. CONCLUSION A short course of calcipotriol plus 5-FU treatment on the face and scalp is associated with induction of robust T cell immunity and Trm formation against AKs and significantly lowers the risk of SCC development within 3 years of treatment.

Abstract
BACKGROUND Preoperative immunonutrition has been proposed to reduce the duration of hospital stay and infective complications following major elective surgery in patients with gastrointestinal malignancy. A multicentre 2 × 2 factorial RCT was conducted to determine the impact of preoperative and postoperative immunonutrition versus standard nutrition in patients with oesophageal cancer. METHODS Patients were randomized before oesophagectomy to immunonutrition (IMPACT® ) versus standard isocaloric/isonitrogenous nutrition, then further randomized after operation to immunonutrition versus standard nutrition. Clinical and quality-of-life outcomes were assessed at 14 and 42 days after operation on an intention-to-treat basis. The primary outcome was the occurrence of infective complications. Secondary outcomes were other complications, duration of hospital stay, mortality, nutritional and quality-of-life outcomes (EuroQol EQ-5D-3 L™, European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 and EORTC QLQ-OES18). Patients and investigators were blinded until the completion of data analysis. RESULTS Some 278 patients from 11 Australian sites were randomized; two were excluded and data from 276 were analysed. The incidence of infective complications was similar for all groups (37 per cent in perioperative standard nutrition group, 51 per cent in perioperative immunonutrition group, 34 per cent in preoperative immunonutrition group and 40 per cent in postoperative immunonutrition group; P = 0·187). There were no significant differences in any other clinical or quality-of-life outcomes. CONCLUSION Use of immunonutrition before and/or after surgery provided no benefit over standard nutrition in patients undergoing oesophagectomy.

Abstract
AIM: Safer and shorter antituberculosis treatment (ATT) regimens represent the unmet medical need. PATIENTS & METHODS The patients were randomly assigned into two arms: the first (n = 137) received once-daily sublingual honey lozenge formulated with botanical immunomodulator Immunoxel and the second (n = 132) received placebo lozenges along with conventional ATT. Immunoxel and placebo arms were demographically similar: 102 versus 106 had drug-susceptible TB; 28 versus 20 multidrug-resistant TB (MDR-TB); 7 versus 7 extensively drug-resistant TB (XDR-TB); and 22 versus 20 TB-HIV. The primary end point was sputum smear conversion. RESULTS After 1 month 87 out 132 (65.9%) of Immunoxel recipients became sputum smear negative, whereas 32 out of 127 (25.2%) in placebo group had converted (p < 0.0001). Sputum clearance produced by Immunoxel was equally effective across all forms of TB. In the immunotherapy arm the average weight gain was 2 kg, but placebo recipients gained only 0.6 kg. Immunoxel reduced TB-associated inflammation as evidenced by defervescence and normalization of elevated leukocyte counts and erythrocyte sedimentation rate. No adverse effects were seen at any time. The liver function tests indicate that ATT-caused hepatotoxicity was counteracted by Immunoxel. These results are in agreement with prior 20 trials of Immunoxel conducted over the past 17 years. CONCLUSION Immunoxel is affordable, safe, effective, fast-acting, commercially available immunotherapeutic intervention to supplement conventional TB chemotherapy. Clinicaltrials.gov ID: NCT01061593.

Nutricion hospitalaria. 2015;(4):1676-82
Abstract
BACKGROUND malnutrition is a common complication in patients with cancer and is associated with immunosuppression and alterations with inflammatory response. OBJECTIVE the aim of our study was to evaluate the effect of enteral nutrition supplemented with two enteral formulas on inflammatory markers (CRP, IL-6 and FNTα) in cancer patients undergoing chemotherapy. DESIGN AND METHODS randomized control trial, conducted at the Hospital Juarez of Mexico in patients with cancer undergoing chemotherapy with IRN < 97.5 and SGA B/C. Patients were randomly allocated to two groups: group I (immunomodulatory), group II (high ω3). The intervention began on the first day of chemotherapy until day 10 after. We evaluated nutritional status and an inflammatory marker on days 0, +5, +10 QT. Statistical analysis was performed with T Student, x2 and analysis of variance for repeated measurements. P < 0.05 was considered statistically significant. RESULTS a total of 29 patients were analyzed, 27 (62.8%) females and 16 (37.2%) males. Mean age 43.91 + 11.3 years old. Malnutrition prevalence was 48.8% moderate and 51.2% severe. Prealbumin levels significantly increase in group II vs group I (p < 0.05). Both groups maintenance body weight, lean mass and fat mass. No decrease levels of CRP, IL-6 and FNTα. CONCLUSIONS enteral supplementation during chemotherapy inhibits nutritional deterioration and maintenance body weight and lean mass. No decreased levels of inflammatory markers.

Abstract
BACKGROUND Statin intolerance has been a major limitation in the use of statins, especially at higher doses. New effective treatments are needed for lowering low-density lipoprotein cholesterol (LDL-C) in patients who cannot tolerate daily statin doses. OBJECTIVE ODYSSEY ALTERNATIVE (NCT01709513) evaluates efficacy and safety of alirocumab, a fully human proprotein convertase subtilisin/kexin type 9 monoclonal antibody, in patients with well-documented statin intolerance and moderate to very high cardiovascular risk. METHODS This is a phase 3, multicenter, randomized, double-blind, double-dummy study in statin-intolerant patients. Intolerance was defined as inability to take at least 2 different statins because of muscle-related adverse events (AEs), 1 at the lowest approved starting dose. Patients first received single-blind subcutaneous and oral placebo for 4 weeks, and were withdrawn if they developed muscle-related AEs after the placebo treatment. Continuing patients were randomized (2:2:1 ratio) to alirocumab 75 mg self-administered via single 1 mL prefilled pen every 2 weeks or ezetimibe 10 mg/day or atorvastatin 20 mg/day (statin rechallenge), for 24 weeks. Alirocumab dose was increased to 150 mg every 2 weeks (also 1 mL) at week 12 depending on week 8 LDL-C level. The primary endpoint is percent change in LDL-C from baseline to week 24 by intent-to-treat analysis. Muscle-related AEs were assessed by spontaneous patient reports and clinic queries. RESULTS A total of 314 patients have been randomized. CONCLUSIONS This is the first and only study of a new class of LDL-C-lowering agents in patients selected with a rigorously documented intolerance to statins, using a placebo run-in and statin control arm.

Abstract
INTRODUCTION Previous studies have demonstrated that oxidative stress by mediating the excessive production of reactive oxygen species is involved in tissue damage and organ failure during and after surgery. The impact of the preoperative immunonutrition including antioxidants on the postoperative course of patients undergoing hepatic surgery was investigated in this pilot study. PATIENTS AND METHODS Twenty-three living donor liver transplantation (LDLT) donors were randomly assigned to either an experimental (AO) group, received a commercial supplement enriched with antioxidant nutrients for each of the 5 days immediately prior to surgery while maintaining normal food intake, or a control (CT) group, administered no supplement. Antioxidative capacity was measured by spectrophotometry of patient serum using a free-radical analytical system. RESULTS The antioxidative capacity of 90.9% patients in the AO group increased after immunonutrition. Compared to the CT group, the AO group was found to have higher antioxidant capacity and transferrin levels; lower WBC, lymphocyte, and neutrophil counts; and briefer duration of postoperative fever during the postsurgical period. No significant differences were found between the 2 groups regarding the nutritional parameters; liver functioning parameters; immunological parameters; intraoperative factors; postoperative outcomes. CONCLUSION Preoperative immunonutrition including antioxidants might play a beneficial role in improving postsurgical immunological response but the modest biological advantage was not associated with any significant clinical outcome.

Abstract
Immunoxel (Dzherelo) is a water-alcohol extract of medicinal plants used in Ukraine as an adjunct immunotherapy to TB and HIV therapy. Four types of solid sublingual formulations of Immunoxel were made: sugar dragées, sugar-coated pills, gelatin pastilles and dried-honey lozenges. They were administered once-daily along with TB drugs. After 1 month, 84.1% of TB patients became sputum-negative with rates in individual groups of 89.5, 70, 76.9 and 100%, respectively. The conversion rate was independent of bodyweight, age, gender, differences in chemotherapy regimens or whether subjects had newly diagnosed TB, re-treated TB, multidrug-resistant TB or TB with HIV coinfection. Patients experienced earlier clinical improvement, faster defervescence, weight gain, a higher hemoglobin content and reduced inflammation as evidenced by lower leukocyte counts and erythrocyte sedimentation rate. By contrast, in the placebo group, only 19% of patients had converted. These findings imply that mucosal delivery of solid Immunoxel is equivalent to the original liquid formula given per os twice-daily for 2-4 months.
