On April 26, 2016 Celsion Corporation (NASDAQ: CLSN), an oncology drug development company, reported that the first patient in China has been enrolled in its ongoing global Phase III OPTIMA Study evaluating ThermoDox, Celsion’s proprietary heat-activated liposomal encapsulation of doxorubicin, in combination with radiofrequency ablation standardized to 45 minutes (sRFA) versus sRFA alone to treat newly diagnosed patients with primary liver cancer, also known as hepatocellular carcinoma (HCC) (Press release, Celsion, APR 26, 2016, View Source [SID:1234511405]).

The pivotal, double-blind, placebo-controlled OPTIMA Study is expected to enroll up to 550 patients globally, and has been successfully enrolling patients at 50 clinical sites in 12 different countries in North America, Europe and Asia Pacific. In December 2015, the Company announced that it had received a Clinical Trial Application (CTA) approval from the China Food and Drug Administration (CFDA) to conduct the OPTIMA Study at up to 20 additional clinical sites in China. The Company aims to enroll more than 200 patients in the China territory, the minimum number required by the CFDA to file a New Drug Application (NDA), assuming positive clinical results.

"The enrollment of the first patient in China represents a significant milestone for the OPTIMA program," said Michael H. Tardugno, Celsion’s chairman, president and chief executive officer. "With the growing incidence of primary liver cancer in China, representing approximately 50% of the 850,000 cases diagnosed annually, this country is an important element of our global registration and commercialization strategy for ThermoDox, and we are committed to driving patient enrollment in this region as we execute our OPTIMA study."

"Survival data from the subgroup analysis in the HEAT study underscore the potential of ThermoDox in combination with sRFA to serve as a potentially curative treatment in primary liver cancer, where very limited treatment options currently exist," said Dr. Nicholas Borys, Celsion’s chief medical officer. "We look forward to working with our colleagues in China and the global research team to further explore ThermoDox in this setting."

The primary endpoint for the OPTIMA Study is overall survival (OS). The statistical plan calls for two preplanned interim efficacy analyses by an independent Data Monitoring Committee (iDMC). The design of the OPTIMA Study is supported by a retrospective analysis of a large subgroup of 285 patients in the Company’s previous 701 patient HEAT Study in primary liver cancer. In a subgroup of 285 HEAT Study participants, ThermoDox plus standardized RFA demonstrated a statistically significant improvement in survival of over two years compared to standardized RFA alone. In this large subgroup, the median overall survival in the ThermoDox plus standardized RFA arm was approximately 80 months (6 ½ years), which is considered a curative treatment for HCC.

Anti-tumor cellular immunotherapies that implement a suicide gene system can limit potential undesirable effects. In a haplo-identical bone marrow transplant clinical trial, over 90% of iCaspase-9-expressing cells were eradicated after AP1903 exposure, and signs of graft-versus-host disease disappeared. Nevertheless, low numbers of genetically-modified T cells survived this treatment. We studied genetically-modified cell lines (GMCL) that carried a dual iCaspase-9/ΔCD19 DNA construct (ΔCD19=truncated CD19). With AP1903 exposure, a low percentage of cells (1.47%±0.67%; n=5 replications) persisted in-vitro. Repeated exposures to increasing AP1903 doses generated low (GMCLLR) and high AP1903-responders (GMCLHR), which expressed different levels of surface ΔCD19and intracellular iCaspase-9. Compared to GMCLHR, GMCLLR exhibited higher methylation of 5′-long-terminal repeat (LTR) promoters, both in the number of sequences with at least one methylated CpG (16 vs 51.5%, respectively) and in the number of CpG islands (1.2 vs 8.9%, respectively). Four days of 5-azacytidine exposure reduced methylation and increased ΔCD19 and iCaspase-9 expression. Interestingly, LTR demethylation restored GMCLLR sensitivity to AP1903 by 24.3-fold (1.8 vs 43.8%) without affecting GMCLHR. We showed that 5’LTR-methylation inhibited transgene expression and caused AP1903 hypo-responsiveness. Treating with a hypomethylating agent restored AP1903 sensitivity. This approach can be applied in further clinical trials to improve iCaspase-9 response if low response is detected.Gene Therapy accepted article preview online, 25 April 2016. doi:10.1038/gt.2016.39.

To prospectively test the diagnostic accuracy of the percentage of prostate specific antigen (PSA) isoform [-2]proPSA (%p2PSA) and the Prostate Health Index (PHI), and to determine their role for discrimination between significant and insignificant prostate cancer at initial and repeat prostate biopsy in men aged ≤65 years.
The diagnostic performance of %p2PSA and PHI were evaluated in a multicentre study. In all, 769 men aged ≤65 years scheduled for initial or repeat prostate biopsy were recruited in four sites based on a total PSA (t-PSA) level of 1.6-8.0 ng/mL World Health Organization (WHO) calibrated (2-10 ng/mL Hybritech-calibrated). Serum samples were measured for the concentration of t-PSA, free PSA (f-PSA) and p2PSA with Beckman Coulter immunoassays on Access-2 or DxI800 instruments. PHI was calculated as (p2PSA/f-PSA × √t-PSA). Uni- and multivariable logistic regression models and an artificial neural network (ANN) were complemented by decision curve analysis (DCA).
In univariate analysis %p2PSA and PHI were the best predictors of prostate cancer detection in all patients (area under the curve [AUC] 0.72 and 0.73, respectively), at initial (AUC 0.67 and 0.69) and repeat biopsy (AUC 0.74 and 0.74). t-PSA and %f-PSA performed less accurately for all patients (AUC 0.54 and 0.62). For detection of significant prostate cancer (based on Prostate Cancer Research International Active Surveillance [PRIAS] criteria) the %p2PSA and PHI equally demonstrated best performance (AUC 0.70 and 0.73) compared with t-PSA and %f-PSA (AUC 0.54 and 0.59). In multivariate analysis PHI we added to a base model of age, prostate volume, digital rectal examination, t-PSA and %f-PSA. PHI was strongest in predicting prostate cancer in all patients, at initial and repeat biopsy and for significant prostate cancer (AUC 0.73, 0.68, 0.78 and 0.72, respectively). In DCA for all patients the ANN showed the broadest threshold probability and best net benefit. PHI as single parameter and the base model + PHI were equivalent with threshold probability and net benefit nearing those of the ANN. For significant cancers the ANN was the strongest parameter in DCA.
The present multicentre study showed that %p2PSA and PHI have a superior diagnostic performance for detecting prostate cancer in the PSA range of 1.6-8.0 ng/mL compared with t-PSA and %f-PSA at initial and repeat biopsy and for predicting significant prostate cancer in men aged ≤65 years. They are equally superior for counselling patients before biopsy.

In December 2014, we nominated AP32788 for clinical development and are currently conducting studies necessary to support the filing of an investigational new drug (IND) application. We expect to file the IND by the end of 2015 and to commence a Phase 1/2 proof-of-concept clinical trial of AP32788 in 2016.
