KNOXVILLE, TN, /GLOBE NEWSWIRE/ -- Provectus (OTCQB: PVCT) today provided an update on the Company's gastrointestinal (GI) cancer clinical development program for its lead investigational drug PV-10, which is administered percutaneously when targeting liver tumors.
Provectus' ongoing, multi-center, open-label, Phase 1 clinical trial of PV-10 for patients with hepatic lesions (NCT00986661) - a "basket study" open to patients with different liver tumor types1 - has expanded to include a single-site cohort of 10 uveal melanoma patients with hepatic metastases. This site is MD Anderson Cancer Center in Houston, Texas, and the principal investigator for the basket study's new cohort is Sapna Patel, MD. Eligible metastatic uveal melanoma patients may receive either single agent PV-10 or PV-10 in combination with standard of care checkpoint inhibition.
The Company currently plans to present initial data from the metastatic uveal melanoma cohort at a medical conference in the second half of 2018, and also plans to present updated data from the entire basket study at a medical conference in the first half of 2019.
Dominic Rodrigues, Vice Chair of the Company's Board of Directors, said, "Uveal melanoma is a rare disease, where almost half of all patients develop metastases and the vast majority of them first present with liver metastasis. Treatments for metastatic uveal melanoma, like checkpoint inhibition, typically have very low response rates."
Mr. Rodrigues added, "Our metastatic uveal melanoma cohort expansion of the Company's liver basket study, like Provectus' ongoing, parallel, Phase 1 clinical trial of symptomatic neuroendocrine tumors of the liver, continues to grow the GI cancer-focused drug development of PV-10. This new work further explores the use of the Company's small molecule oncolytic immunotherapy for another cancer indication with substantial unmet need or that is a rare disease."
About Metastatic Uveal Melanoma
Uveal melanoma is a rare disease that is biologically and clinically distinct from cutaneous melanoma.2,3 Nearly 50% of uveal melanoma patients develop metastatic disease, with 80-90% of them presenting with liver as the first site of disease involvement.2,3,4 Outcomes of metastatic uveal melanoma are poor, with a median overall survival of 12 months and an 80% mortality rate within the first year.5 A new set of National Comprehensive Cancer Network (NCCN) guidelines for the diagnosis and management of uveal melanoma were created in 2018. 6
Provectus' lead investigational oncology drug product, PV-10, the first small molecule oncolytic immunotherapy, can induce immunogenic cell death. PV-10 is undergoing clinical study for adult solid tumor cancers, like melanoma and cancers of the liver, and preclinical study for pediatric cancers.
