Abstract
Body weight loss is frequently regarded as negatively related to outcomes in patients with malignancies. This retrospective analysis of the FIRE-3 study evaluated the evolution of body weight in patients with metastatic colorectal cancer (mCRC). FIRE-3 evaluated first-line FOLFIRI (folinic acid, fluorouracil and irinotecan) plus cetuximab or bevacizumab in mCRC patients with RAS-WT tumors (ie, wild-type in KRAS and NRAS exons 2-4). The prognostic and predictive relevance of early weight loss (EWL) regarding patient outcomes and treatment side effects were evaluated. Retrospective data on body weight during first 6 months of treatment were evaluated (N = 326). To correlate with efficacy endpoints and treatment side effects, patients were grouped according to clinically significant EWL ≥5% and <5% at Month 3. Age constituted the only significant predictor of EWL following a linear relationship with the corresponding log odds ratio (P = .016). EWL was significantly associated with the incident frequencies of diarrhea, edema, fatigue, nausea and vomiting. Further, a multivariate analysis revealed EWL to be an independent negative prognostic factor for overall survival (32.4 vs 21.1 months; hazard ratio [HR]: 1.64; 95% confidence interval [CI] = 1.13-2.38; P = .0098) and progression-free survival (11.8 vs 9.0 months; HR: 1.72; 95% CI = 1.18-2.5; P = .0048). In conclusion, EWL during systemic treatment against mCRC is significantly associated with patient age. Patients exhibiting EWL had worse survival and higher frequencies of adverse events. Early preventative measures targeted at weight maintenance should be evaluated, especially in elderly patients being at highest risk of EWL.

Abstract
BACKGROUND Immune checkpoint inhibitors and chemotherapy can synergistically increase efficacy in a variety of malignancies. We conducted this phase Ib/II study to assess the safety and efficacy of anti-PD-1 antibody camrelizumab in combination with FOLFOX4 for treatment-naive advanced hepatocellular carcinoma (aHCC). METHODS This open-label, multicenter phase Ib/II study (NCT03092895) enrolled patients with aHCC and without prior systemic treatment for treatment with camrelizumab (3 mg/kg) and FOLFOX4 every two weeks. First, six patients were enrolled, followed by an additional 28 patients after dose-limiting toxicity cases were determined to be <33% of patients. The primary endpoint was tolerability and safety of treatment. RESULTS A total of 34 aHCC patients were enrolled and received study treatment. No dose-limiting toxicity were observed in the first six patients enrolled. Twenty-nine (85.3%) of the total 34 patients had grade ≥3 treatment-related adverse events (TRAEs), with the most common ones being decreased neutrophil count (55.9%) and decreased white blood cell count (38.2%). No TRAEs-related deaths occurred. The objective response and disease control rate were 29.4% (95% CI, 15.1-47.5) and 79.4% (95% CI, 62.1-91.3), respectively. The median duration of response, progression-free survival, and overall survival was 6.9 months (range, 3.3-11.5), 7.4 months (95% CI, 3.9-9.2), and 11.7 months (95% CI, 8.2-22.0), respectively. CONCLUSION Camrelizumab combined with FOLFOX4 for first-line treatment of patients with aHCC showed good safety and tolerability, with promising preliminary antitumor activity.

Abstract
BACKGROUND Stratification of patients with stage III colon cancer into low (T1-3N1) and high (T4 and/or N2) risk groups is used to guide the duration of adjuvant chemotherapy. We determined the relative contribution of clinical and molecular features to survival by risk group. MATERIALS & METHODS Stage III colon cancer (N = 5337) patients from two adjuvant trials of FOLFOX ± cetuximab [N0147 (Alliance), PETACC-8] were risk grouped, then subgrouped by clinical features and molecular variables [KRAS and BRAF/mismatch repair (MMR) combined variable]. Distributions of disease-free survival (DFS), overall survival (OS), and survival after recurrence (SAR) were estimated. In multivariable Cox models, backward elimination was performed for analysis of candidate predictors of outcomes. Relative contributions of model-selected variables to outcomes by risk group were calculated using χ2. RESULTS Among low risk tumours, mutant KRAS and male gender were significantly associated with poorer OS multivariately. In high risk tumours, significantly poorer OS was observed for right sidedness and for mutant KRAS and BRAFV600E/pMMR, subgroups. Specifically, BRAFV600E/pMMR (OS: HR = 1.75; 95% CI: 1.36-2.24; Padj<.0001) and right- versus left-sidedness were associated with significantly poorer DFS, OS (HR = 1.56; 95% CI: 1.31-1.83; Padj<.0001), and SAR (HR = 1.64; 95% CI: 1.37-1.95; Padj<.0001). Poor prognosis of mutant KRAS for DFS and OS was similar among risk groups. BRAF/MMR and sidedness were associated with poorer SAR in both low and high risk tumours. Age, gender, and KRAS were the top three relative contributors to DFS and OS among low risk tumours; sidedness ranked first for DFS and OS, and second to BRAF/MMR for SAR among high risk tumours. CONCLUSION Sidedness and BRAF/MMR contributed the most to survival outcomes among high risk tumours and should be interpreted in the context of risk group.

Abstract
Modified FOLFOX6 is an established therapy for patients with metastatic colorectal cancer (mCRC). We conducted a single-arm phase Ib study to address the hypothesis that addition of pembrolizumab to this regimen could safely and effectively improve patient outcomes (NCT02375672). The relationship between immune biomarkers and clinical response were assessed in an exploratory manner. Patients with mCRC received concurrent pembrolizumab and modified FOLFOX6. The study included safety run-in for the first six patients. The primary objective was median progression-free survival (mPFS), with secondary objectives including median overall survival, safety, and exploratory assessment of immune changes. To assess immunological impact, peripheral blood was collected at baseline and during treatment. The levels of soluble factors were measured via bioplex, while a panel of checkpoint molecules and phenotypically defined cell populations were assessed with flow cytometry and correlated with RECIST and mPFS. Due to incidences of grade 3 and grade 4 neutropenia in the safety lead-in, the dose of mFOLFOX6 was reduced in the expansion cohort. Median PFS was 8.8 months and median OS was not reached at data cutoff. Best responses of stable disease, partial response, and complete response were observed in 43.3%, 50.0%, and 6.7% of patients, respectively. Several soluble and cellular immune biomarkers were associated with improved RECIST and mPFS. Immunosuppressive myeloid and T cell subsets that were analyzed were not associated with response. Primary endpoint was not superior to historic control. Biomarkers that were associated with improved response may be informative for future regimens combining chemotherapy with immune checkpoint inhibitors.

Abstract
PURPOSE We evaluated study outcomes in patients enrolled in Asian regions in the phase III EMBRACA trial of talazoparib vs. chemotherapy. MATERIALS AND METHODS Patients with human epidermal growth factor receptor 2-negative germline BRCA1/2-mutated advanced breast cancer who received prior chemotherapy were randomized 2:1 to talazoparib 1 mg/day or chemotherapy (physician's choice). Primary endpoint was progression-free survival (PFS) per independent central review in the intent-to-treat (ITT) population. This post-hoc analysis evaluated efficacy/safety endpoints in the ITT population of patients enrolled in Asian regions. RESULTS Thirty-three patients were enrolled at Asian sites (talazoparib, n=23; chemotherapy, n=10). Baseline characteristics were generally comparable with the overall EMBRACA population. In Asian patients, median PFS was 9.0 months (95% confidence interval [CI], 3.0 to 15.2) for talazoparib and 7.1 months (95% CI, 1.2 to not reached) for chemotherapy (hazard ratio [HR], 0.74 [95% CI, 0.22 to 2.44]). Objective response rate was numerically higher for talazoparib vs. chemotherapy (62.5% [95% CI, 35.4 to 84.8] vs. 25.0% [95% CI, 3.2 to 65.1]). Median overall survival was 20.7 months (95% CI, 9.4 to 40.1) versus 21.2 months (95% CI, 2.7 to 35.0) (HR, 1.41 [95% CI, 0.49 to 4.05]). In Asian patients, fewer grade 3/4 adverse events (AEs), serious AEs (SAEs), grade 3/4 SAEs, and AEs resulting in dose reduction/discontinuation occurred with talazoparib than chemotherapy; for talazoparib, the frequency of these events was lower in Asian patients versus overall EMBRACA population. CONCLUSION In this subgroup analysis, talazoparib numerically improved efficacy versus chemotherapy and was generally well tolerated in Asian patients, with fewer grade 3/4 treatment-emergent AE (TEAEs), SAEs, and TEAEs leading to dose modification vs. the overall EMBRACA population.

Abstract
OBJECTIVE/BACKGROUND The purpose was to determine whether adding Pmab versus no Pmab to an adjuvant regimen of hepatic arterial infusion (HAI) of floxuridine (FUDR) plus systemic (SYS) leucovorin, fluorouracil, and irinotecan (FOLFIRI) improves 15-month recurrence-free survival for patients with RAS wild-type colorectal cancer. Secondary endpoints included overall survival, toxicity, and influence of predictive biomarkers. METHODS This phase II trial randomized patients with KRAS wild-type resected colorectal liver metastases to adjuvant HAI FUDR + SYS FOLFIRI +/- Pmab (NCT01312857). Patients were stratified by clinical risk score and previous chemotherapy. Based on an exact binomial design, if one arm had ≥24 patients alive and disease-free at 15 months that regimen was considered promising for further investigation. RESULTS Seventy-five patients were randomized. Patient characteristics and toxicity were not different in the 2 arms, except for rash in +Pmab arm. Grade 3/4 elevation in bilirubin or alkaline phosphatase did not differ in the 2 arms. Twenty-five (69%; 95% CI, 53-82) patients in the Pmab arm versus 18 (47%; 95% CI, 32-63) patients in the arm without Pmab were alive and recurrence-free at 15 months. Only the Pmab arm met the decision rule, while the other arm did not. After median follow-up of 56.6 months, 3-year recurrence-free survival was 57% (95% CI, 43-76) and 42% (95% CI, 29-61), and 3-year overall survival was 97% (95% CI, 90-99) and 91% (95% CI, 83-99), +/- Pmab, respectively. CONCLUSIONS The addition of Pmab to HAI FUDR + SYS FOLFIRI showed promising activity without increased biliary toxicity and should be further investigated in a larger trial.

Efficacy and safety of sorafenib plus vitamin K treatment for hepatocellular carcinoma: A phase II, randomized study.
Haruna, Y, Yakushijin, T, Kawamoto, S
Cancer medicine. 2021;(3):914-922
Abstract
The previous retrospective study suggested that dosing vitamin K may enhance the anticancer action of sorafenib against hepatocellular carcinoma. To confirm it, we performed a phase II, randomized, open-label study. Patients with hepatocellular carcinoma were randomly assigned to receive sorafenib + vitamin K2 (menatetrenone, 45 mg daily, orally) or sorafenib only. Between 1 May 2012 and 1 May 2016, 68 patients were screened. Forty-four eligible patients were assigned at a 1:1 ratio to each cohort. The objective response rate in the vitamin K-dosed group was significantly higher than that in the sorafenib only group (27.3% vs 4.5%, respectively; p = 0.039). The median time of progression-free survival was significantly extended in the vitamin K-dosed group compared with the sorafenib only group (4.9 months vs 2.7 months, respectively; hazard ratio (HR), 0.44; 95% confidence interval (CI): 0.21-0.89; p = 0.018). Although there was no significant difference between the two groups in the median time of overall survival, patients in the vitamin K-dosed group with a complete response or partial response achieved a significantly extended median time of overall survival compared with the other patients in the vitamin K-dosed group or the patients in the sorafenib only group (26.1 months vs 9.0 months; HR, 0.34; 95% CI: 0.11-0.95; p = 0.046 or 11.5 months; HR, 0.16; 95% CI: 0.034-0.70; p = 0.006, respectively). Dosing vitamin K could augment the anticancer action of sorafenib against HCC.

Abstract
PURPOSE Palbociclib, a cyclin-dependent kinase (CDK) 4/6 inhibitor, blocks proliferation in a RB and cyclin D-dependent manner in preclinical prostate cancer models. We hypothesized that cotargeting androgen receptor and cell cycle with palbociclib would improve outcomes in patients with metastatic hormone-sensitive prostate cancer (mHSPC). PATIENTS AND METHODS A total of 60 patients with RB-intact mHSPC were randomized (1:2) to Arm 1: androgen deprivation (AD) or Arm 2: AD + palbociclib. Primary endpoint was PSA response rate (RR) after 28 weeks of therapy. Secondary endpoints included safety, PSA, and clinical progression-free survival (PFS), as well as PSA and radiographic RR. Tumors underwent exome sequencing when available. Circulating tumor cells (CTC) were enumerated at various timepoints. RESULTS A total of 72 patients with mHSPC underwent metastatic disease biopsy and 64 had adequate tissue for RB assessment. A total of 62 of 64 (97%) retained RB expression. A total of 60 patients initiated therapy (Arm 1: 20; Arm 2: 40). Neutropenia was the most common grade 3/4 adverse event in Arm 2. Eighty percent of patients (Arm 1: 16/20, Arm 2: 32/40; P = 0.87) met primary PSA endpoint ≤4 ng/mL at 28 weeks. PSA undetectable rate at 28 weeks was 50% and 43% in Arms 1 and 2, respectively (P = 0.5). Radiographic RR was 89% in both arms. Twelve-month biochemical PFS was 69% and 74% in Arms 1 and 2, respectively (P = 0.72). TP53 and PIK3 pathway mutations, 8q gains, and pretreatment CTCs were associated with reduced PSA PFS. CONCLUSIONS Palbociclib did not impact outcome in RB-intact mHSPC. Pretreatment CTC, TP53 and PIK3 pathway mutations, and 8q gain were associated with poor outcome.

Abstract
OBJECTIVES Macropinocytosis promotes internalization of albumin into cells to serve as a nutrient supply and is constitutively driven by signaling pathways frequently hyperactivated in head and neck squamous-cell carcinoma (HNSCC). In this way, drugs bound to albumin may selectively target HNSCC. nab-paclitaxel is a nanoparticle albumin-bound formulation of paclitaxel that improves drug delivery into tumor compared to paclitaxel. The primary aim of this single-arm, multicenter, phase 2 trial was to determine if nab-paclitaxel, cetuximab, and carboplatin (CACTUX regimen) would result in longer progression-free survival (PFS) than the historical regimen (EXTREME 5-fluorouracil, cetuximab, and a platinum). MATERIALS AND METHODS Patients with untreated recurrent or metastatic HNSCC received six, three-week cycles of nab-paclitaxel, cetuximab, and carboplatin, followed by maintenance nab-paclitaxel and cetuximab until progression. We hypothesized the median PFS with CACTUX would be 35% longer than with EXTREME (corresponding to 7.6 vs 5.6 months; power 0.80, α = 0.05, one-sided test, n = 70). Secondary outcomes included objective response rate (ORR) and overall survival (OS). RESULTS Seventy-four patients enrolled into the trial; seventy were evaluable. The median PFS was 6.1 months (95% CI, 4.1-7.4). The ORR was 60%. Median follow-up was 18 months (IQR: 4.7-23). The median OS was 17.8 months (95% CI, 8.5-21.7) for all patients, and 19.8 months (95% CI, 10.9-22.0) for human papillomavirus (HPV)-related oropharynx SCC and 14.0 months (95% CI, 4.6-23.3) for HPV-unrelated HNSCC. CONCLUSION Among patients with recurrent or metastatic HNSCC, CACTUX did not result in a longer PFS than historical EXTREME. However, CACTUX did result in a more favorable ORR and OS.

Abstract
Nintedanib is a triple angiokinase inhibitor of vascular endothelial growth factor receptor 1-3, fibroblast growth factor receptor 1-3 and platelet-derived growth factor receptor-a/-b. Thereby, it targets angiogenic escape mechanisms. The trial TyRosine kinase Inhibitor for the treatment of Chemorefractory Colorectal Cancer (TRICC-C) trial evaluates the addition of nintedanib to mFOLFOX6 (fluorouracil, folinic acid and oxaliplatin) in patients with metastatic colorectal cancer (mCRC). TRICC-C is a randomised controlled, double-blinded, phase II trial in mCRC patients that received a first-line non-oxaliplatin containing chemotherapy. Patients received mFOLFOX6 + nintedanib (F + N) (2 × 200 mg p.o./d, d1-d14) or mFOLFOX6 + placebo (F + P), in a 1:1 ratio. Primary endpoint was median progression free survival (mPFS) and secondary overall response rate (ORR), overall survival (OS) and safety. Fifty-three patients (27 F + N; 26 F + P) were randomised between 12/2012 and 5/2016 (scheduled n = 180). The trial was terminated prematurely due to slow accrual. The trial did not reach its primary endpoint but mPFS, median overall survival (mOS) and disease control rate (DCR) were numerically higher in the F + N arm compared to the F + P arm; however, the difference was not significant (mPFS: F + P: 4.6 months vs F + N: 8.1 months; HR 0.65; 95% CI 0.32-1.30; P = .2156; mOS: F + P: 9.9 months vs F + N: 17.1 months; HR 1.03, 95% CI 0.48-2.23; P = .9387; DCR: F + P: 50% vs F + N: 66,7%; P = .2709). Toxicity was moderate and only different for neutropenia (F + P: 11.5%, F + N: 19.2%) and gastrointestinal disorders (F + P: 65.4%, F + N: 84.6%). Final results show safety and a nonsignificant trend towards improved PFS and DCR for the combination of mFOLFOX6 + nintedanib in the second-line therapy of mCRC.
