Data on Delcath’s PHP Therapy presented at CIRSE 2018

NEW YORK, Sept. 24, 2018 (GLOBE NEWSWIRE) -- Delcath Systems, Inc. (OTCQB: DCTH), an interventional oncology company focused on the treatment of primary and metastatic cancers of the liver, announces that data from a study conducted in Germany of the use of the Delcath Hepatic CHEMOSAT® Delivery System to treat patients with metastatic ocular melanoma with liver metastases, was presented as a poster at the Cardiovascular and Interventional Radiology Society of Europe (CIRSE) annual meeting.

The study entitled Survival and Response of Patients with Metastatic Ocular Melanoma after Chemosaturation Percutaneous Hepatic Perfusion was conducted by M. Zeile, and A. Stang, et al of the Asklepios Barmbek Clinic in Hamburg, Germany. The study retrospectively evaluated response rates and overall survival in 12 patients with ocular melanoma liver metastases after treatment with Delcath’s PHP® Therapy. Five patients had metastases confined to the liver, and seven had additional extra-hepatic metastases. A total of 30 PHP procedures were performed in the sample, and patients received an average of 2.5 treatments.

Results of the study showed the objective response rate (ORR) was 58.3%, and the disease control rate was 91.7% (1 complete response, 6 partial responses, 4 stable disease, and 1 progressive disease). Following the first PHP treatment, progression free survival was 11.7 months and hepatic progression free survival (hPFS) was 18.6 months. Median overall survival (OS) was 30.6 months following the treatment. Of the cohort of 12 patients, three patients were judged to be candidates for surgery following treatment with PHP. Median OS among these patients was 76.8 months, though investigators cautioned that statistical conclusions cannot be drawn from the small sample size.

Commenting on the study, Jennifer K. Simpson, PhD, MSN, CRNP, President & CEO of Delcath Systems, said, "Though the cohort in this study was small, the results are consistent with the positive signals provided by other studies published or presented over the last year. The high ORR and disease control rate observed in this study is particularly encouraging, as these data points are now the primary and secondary endpoints, respectively, for our amended Registration trial in ocular melanoma liver metastases. As the study authors note, the role of secondary surgery following PHP treatment is currently unclear given the small sample size, but we believe points to the promise this therapy may have for appropriately selected patients."

The CIRSE 2018 annual meeting is being held in Lisbon, Portugal September 22-25, 2018.
