Pure Biologics

Pure Biologics is happy to announce that on July 15, 2024 the first patient was dosed with the #drug candidate PBA-0405 in a Phase 0 study. The patient, diagnosed with head and neck squamous cell #carcinoma [HNSCC], was recruited at the Louisiana State University Hospital in Shreveport. Intratumoral administration of PBA-0405 was followed by surgical resection of the #tumor the next day, from which tumor material was secured and prepared for immunohistochemical analysis. The planned immunohistochemical studies are expected to provide data on the pharmacodynamics of PBA-0405, and thus information on the expected #anticancer efficacy of the drug candidate. The analysis will focus on detecting the biomarkers of immune cell activation and tumor cell killing to confirm the therapeutic mode of action of PBA-0405 in the context of the human tumor microenvironment. This is important for the Company’s plans to obtain a strategic partner, which is currently a priority for the Company. The results of the study may be a key factor shaping the project valuation and influencing the decisions of potential pharmaceutical partners. This is a critical milestone for the Company's flagship project PB004. ‘We are extremely pleased to have dosed our first patient in this first-in-man study with PBA-0405, which promises to offer a novel approach to treating cancers. This is a pivotal step in the #development of PBA-0405.’ – says John Weinberg, MD, MBA, Chief Medical Officer at Pure Biologics. The Company expects to complete the study in the coming months and partial results will be monitored during the Study. Results from the first patient are expected within 8 weeks. The study is being conducted by Presage Biosciences, Inc. based in Seattle. #cancer #therapy #immunotherapy #drugcandidate #drugdevelopment #PureBiologics

Pure Biologics proudly announces that it has received approval from the United States Food and Drug Administration (#FDA) for an exploratory Investigational New Drug (eIND) for testing PBA-0111 in a Phase 0 clinical study in solid tumor #cancer patients. The Phase 0 study will be a multicenter, open-label #study conducted in the United States in up to 12 patients with head and neck #carcinoma, soft tissue #sarcoma and triple negative breast cancer. The Phase 0 study will focus on detection of early signs of pharmacodynamic activity of PBA-0111, after a single-dose injection directly in the #tumor, including #immune-cell activation and tumor cell killing, to confirm the PBA-0111 therapeutic mode of action in a real patient setting. Pure Biologics has partnered with Presage Biosciences, Inc. (Seattle, USA) to execute the studies. The Phase 0 study is expected to be completed in the end of 2024. Before then, the Company expects partial results as the study progresses. PBA-0111 is a fully human #antibody #drug candidate targeting GARP in the tumor micro-environment. PBA-0111 alleviates #immuno-suppression, a major obstacle in current immuno-therapy treatment, as well as directly initiates tumor killing by the immune system. The results of research under the PB003G project indicate, in the Company's opinion, clear advantages over drug candidates with promising results in the early stages of clinical development. PB003G is an attractive drug concept with a very strong competitive advantage in the context of commercialization on the cancer therapy market, with potential in the treatment of solid tumors. Studies performed in tumor-bearing humanized mice suggest that PBA-0111 holds great promise for solid tumor #treatment. The Phase 0 clinical study aims at front-load the acquisition of data on effectiveness of PBA-0111 in a human patient setting to further guide clinical development towards market authorization. Dr. Pieter Spee, Chief Scientific Officer of Pure Biologics said: 'The approval of PBA-0111 is a testimony to the dedicated team of researchers involved in PBA-011 development. We are very excited about starting the PBA-0111 Phase 0 study, as it allows us to obtain first proof of the effectiveness of PBA-0111 in human cancer patients two years faster in the PBA-0111 development path than we would be able to obtain in Phase I and II clinical trials.' Dr. Filip Jelen, PhD, MBA, PhD, MBA, co-founder and President of the Management Board of Pure Biologics said: 'These are exciting times for Pure Biologics! After FDA eIND approval for PBA-0405, we have now received FDA eIND approval for PBA-0111 a few months later. The outcome of the planned Phase 0 clinical study will lead to a significant increase in the value of the project. The Company's goal is to conduct a partnering transaction for at least one of the Company’s drug candidates, PBA-0405 and PBA-0111, in the coming year.'

We are happy to inform that we are heading to San Francisco for the Biotech Showcase event during J.P. Morgan Healthcare Week 2024 from January 8 to 11. Our CSO - Pieter Spee - will represent us there! We are looking forward to numerous meetings with international investors and pharma companies. #medtech #biotech #JPMorganHealthcareConference #JPMorganHealthcareWeek #PureBiologics #aptamers #antibodies

We are proud to announce that Pure Biologics has received approval from the U.S. Food and Drug Administration (FDA) for an exploratory Investigational New Drug (eIND) for testing PBA-0405 in a Phase 0 clinical study in solid tumour cancer patients.     About PBA-0405:  PBA-0405 is a fully human IgG1 antibody that targets ROR1, a drug-target found on many solid tumours and B cell malignancies, and rarely on healthy tissues. PBA-0405 has been designed to make tumor cells visible to the immune system. Through a process called afucosylation, PBA-0405 has been engineered to optimally induce tumor killing by so-called cytotoxic immune cells. PBA-0405 is the first ROR1-targeting compound with such mode of action to reach such an advanced stage of research. In preclinical studies, PBA-0405 has shown very promising anti-cancer activity, both in vitro and in vivo, both in a solid tumor model and in a B cell leukemia model.    Phase 0 Study Focus:  The Phase 0 study will focus on detection of early signs of pharmacodynamic activity of PBA-0405, after a single-dose injection directly in the tumor, including immune-cell activation and tumour cell killing, to confirm the PBA-0405 therapeutic mode of action in a real patient setting.    Study Detailes:  In the multi-centre, open label study, performed in the USA, patients with head and neck carcinoma, soft tissue sarcoma and triple negative breast cells cancer will receive a single intra-tumoral injection of PBA-0405. For this, Pure Biologics has partnered with Presage Biosciences, Inc. (Seattle, USA) as CRO to execute the studies. Company aims to complete the Phase 0 clinical study within six months after study initiation.      #ClinicalTrials #CancerResearch #InnovativeTherapies #PBA0405 #PureBiologics #Oncology

Pure Biologics submits the first eIND application!   On November 21, 2023, Pure Biologics took a significant step forward by submitting an exploratory Investigational New Drug (eIND) application to the US Food and Drug Administration (FDA) to request approval for testing PBA-0405 in a Phase 0 clinical study in solid tumor cancer patients.   PBA-0405 is a fully human IgG1 antibody that targets ROR1, a drug-target found on many solid tumors and B cell malignancies. PBA-0405 has been designed to make tumor cells visible to the immune system. Through a process called afucosylation, PBA-0405 has been engineered to optimally induce tumor killing by so-called cytotoxic immune cells. PBA-0405 is the first ROR1-targeting compound with such mode of action to reach such an advanced stage of research.   PBA-0405 has displayed promising anti-cancer activity, both in vitro and in vivo, both in a solid tumor model and in a B cell leukemia model. Now, our focus turns to the Phase 0 clinical study. We aim to detect early signs of PBA-0405's pharmacodynamic activity, such as immune-cell activation and tumor cell destruction, validating its therapeutic potential in real patient scenarios.   The phase 0, multi-center, open-label study will take place in the USA, involving patients with head and neck carcinoma, soft tissue sarcoma, and triple-negative breast cancer. Each patient will receive a single intra-tumoral injection of PBA-0405. Once we secure FDA approval for our eIND application, we plan to wrap up the Phase 0 clinical study within six months after initiation.   At Pure Biologics, we are committed to pushing the boundaries of cancer treatment. We look forward to the next steps in the regulatory process and are hopeful that PBA-0405 will ultimately make a positive impact on the lives of patients.   #PureBiologics #CancerResearch #MedicalInnovation
