Purpose: Reovirus type 3 Dearing (RT3D) replicates preferentially in Ras-activated cancers. RT3D shows synergistic in vitro cytotoxicity in combination with platins and taxanes. The purpose of this phase I/II study was to assess RT3D combined with carboplatin/paclitaxel in patients with advanced cancers.Experimental Design: Patients were initially treated in a dose-escalating, phase I trial with intravenous RT3D days 1 to 5, carboplatin [area under curve (AUC) 5, day 1] and paclitaxel (175 mg/m2, day 1) 3-weekly. RT3D was escalated through three dose levels: 3 × 109, 1 × 1010, and 3 × 1010 TCID50 in cohorts of three. Primary endpoints were to define the maximum tolerated dose and dose-limiting toxicity and to recommend a dose for phase II studies. Secondary endpoints included pharmacokinetics, immune response, and antitumor activity. A subsequent phase II study using the 3 × 1010 TCID50 dose characterized the response rate in patients with head and neck cancer.Results: Thirty-one heavily pretreated patients received study therapy. There were no dose-limiting toxicities during dose-escalation and most toxicities were grade I/II. Overall effectiveness rates were as follows: one patient had a complete response (3.8%), six patients (23.1%) had partial response, two patients (7.6%) had major clinical responses clinically evaluated in radiation pretreated lesions which are not evaluable by Response Evaluation Criteria in Solid Tumors (RECIST), nine patients (34.6%) had stable disease, and eight patients (30.8%) had disease progression. Viral shedding was minimal and antiviral immune responses were attenuated compared with previous single-agent data for RT3D.Conclusions: The combination of RT3D plus carboplatin/paclitaxel is well tolerated with evidence of activity in cancer of the head and neck. A randomized phase III study is currently open for recruitment. Clin Cancer Res; 18(7); 2080–9. ©2012 AACR.

Background. Systemic inflammation is a pathogenic mechanism shared by infection and cancer. Mortality from Covid-19 is strongly linked to systemic cytokine excess. We investigated systemic inflammation as a driver of Covid-19 severity in patients with Covid-19 and cancer. Methods. Between 27/02 and 23/06/2020, OnCovid retrospectively accrued 1,318 consecutive European cancer patients with Covid-19. Patients with myeloma, leukemia, or insufficient data were excluded. The neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), prognostic nutritional index (PNI), modified Glasgow prognostic score (mGPS), and prognostic index (PI) were evaluated for their prognostic potential, with the NLR, PLR, and PNI risk stratifications dichotomized around median values, and the pre-established risk categorizations from literature utilized for the mGPS and PI. Results. 1,071 eligible patients were randomly assorted into a training set (TS, n=529) and validation set (VS, n=542) matched for age (67.9±13.3 TS, 68.5±13.5 VS), presence of >1 comorbidity (52.1% TS, 49.8% VS), development of >1 Covid-19 complication (27% TS, 25.9% VS), and active malignancy at Covid-19 diagnosis (66.7% TS, 61.6% VS). Among all 1,071 patients, deceased patients tended to categorize into poor risk groups for the NLR, PNI, mGPS, and PI (P6 (44.6% vs 28%, P6 30 days 95%CI 1-63, PNI Conclusion. Systemic inflammation drives mortality from Covid-19. Hypoalbuminemia and lymphocytopenia as measured by the PNI are the most accurate predictors of outcome and enable repurposing of the PNI as the OnCovid Inflammatory Score (OIS) as a readily available biomarker of severity.
