Provectus Biopharmaceuticals Announces Presentation of Full Study Data from Metastatic Neuroendocrine Cancer Phase 1 Trial of PV-10® at European Society for Medical Oncology (ESMO) Congress 2021Tuesday September 21, 2021 KNOXVILLE, TN, September 21, 2021 (GLOBE NEWSWIRE) - Provectus (OTCQB: PVCT) today announced that data from an ongoing clinical trial of investigational cancer immunotherapy PV-10 (rose bengal disodium) for the treatment of neuroendocrine tumors (NET) metastatic to the liver (mNET) refractory to somatostatin analogs (SSAs) and peptide receptor radionuclide therapy (PRRT) (NCT02693067) was presented at the European Society for Medical Oncology (ESMO) Congress, held online from September 16-21, 2021. Highlights from the ESMO 2021mNET Presentation:

A copy of the poster is available on Provectus' website at https://www.provectusbio.com/ Simone Leyden, Chief Executive Officer and Co-Founder of NeuroEndocrine Cancer Australia, and International Neuroendocrine Cancer Alliance (INCA) Research Chair, said "The safety and efficacy data from this Phase 1 clinical trial of single-agent PV-10 present a promising therapy for refractory, symptomatic, neuroendocrine cancer patients with liver metastases, a patient population who are underrepresented when it comes to new medical research and treatment options. We look forward to seeing PV-10's future use in this refractory setting, and also in Phase 2 combination therapy testing for earlier lines of neuroendocrine cancer treatment." Dominic Rodrigues, Vice Chair of the Company's Board of Directors, added, "These data may initially position single-agent PV-10 behind somatostatin analogs and peptide receptor radionuclide therapy in the Australian patient treatment setting. Our clinical trial database should lock in the fourth quarter of 2021, providing us the opportunity to finalize data collection and analysis prior to assessing PV-10's regulatory prospects and options." This clinical trial, a single-center study at The Queen Elizabeth Hospital (TQEH) in Adelaide, Australia that completed enrollment in 2020, is led by Tim Price, MBBS, DHlthSc (Medicine), FRACP, Head of Clinical Oncology Research and Chair of the combined Hematology and Medical Oncology Unit at TQEH and Clinical Professor in the Faculty of Medicine at the University of Adelaide. The primary endpoint of the trial is safety. Secondary endpoints include ORR of injected target and measurable bystander lesions, target lesion somatostatin receptor expression, and biochemical response. Disease response assessments are conducted by independent review using Response Evaluation Criteria in Solid Tumors (RECIST) criteria. Six patients in the first cohort each received one percutaneously-administered injection of PV-10 to one target lesion per treatment cycle. Patients in the six-person second cohort can receive PV-10 injections of multiple lesions per cycle. About PV-10 Intralesional (IL) administration of PV-10 for the treatment of solid tumor cancers can yield immunogenic cell death within hours of tumor injection, and induce tumor-specific reactivity in circulating T cells within days. This IL PV-10-induced functional T cell response may be enhanced and boosted in combination with immune checkpoint blockade (CB). In CB-refractory advanced cutaneous melanoma, IL PV-10 may restore disease-specific T cell function, which may also be prognostic of clinical response. IL PV-10 has been administered to over 450 patients with cancers of the skin and of the liver. It is administered under visual, tactile or ultrasound guidance to superficial malignancies, and under CT or ultrasound guidance to tumors of the liver. Systemic administration of PV-10 is also undergoing preclinical study as prophylactic and therapeutic treatments for refractory and high-risk adult solid tumor cancers, and as a treatment for relapsed and refractory blood cancers. About NeuroEndocrine Cancer Australia NeuroEndocrine Cancer Australia is the only Australian not-for-profit medical charity focused on neuroendocrine tumors. It was co-founded in 2009 by Simone Leyden and her brother Dr. John Leyden through shared experiences with their sister Kate's diagnosis of pancreatic neuroendocrine carcinoma and liver metastases.
