CASTRES, France, June 5, 2024 /PRNewswire/ -- Pierre Fabre Laboratories today announced the filing of an investigational new drug ("IND") application to the U.S. Food and Drug Administration ("FDA") to initiate a first-in-human (FIH) Phase I/II clinical trial with PFL-002/VERT-002 for solid tumors including non-small cell lung cancer (NSCLC). Continue Reading View PDF The PFL-002/VERT-002 Phase I/II trial is a multi-center, international study aimed to assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and preliminary efficacy of PFL-002/VERT-002 in NSCLC patients with MET alterations, including those acquired as resistance mechanism to other treatments. The FDA will review the application and determine its acceptability. "We are looking forward to initiating the first-in-human trial of PFL-002/VERT-002 later this year. We are confident that this new drug holds significant promise, as a novel therapeutic option with a differentiated mechanism of action, for patients facing MET-altered solid tumors, including NSCLC" said Francesco Hofmann, Head of Research and Development for Medical Care at Pierre Fabre Laboratories. About PFL-002/VERT-002 PFL-002/VERT-002 is a monoclonal antibody developed by Vertical Bio, offering a unique and differentiating mechanism of action, acting as a degrader of c-MET, a known disease driver in patients with solid tumors, including non-small cell lung cancer (NSCLC) presenting mutations or amplification of MET. The antibody has been optimized preclinically by Vertical Bio, which has been acquired by Pierre Fabre Laboratories. Pierre Fabre Laboratories is progressing PFL-002/VERT-002 into clinical development and hope to enroll a first patient in the FIH trial by end 2024. About Pierre Fabre R&D Pipeline and Portfolio Pierre Fabre Laboratories has expanded its efforts in precision oncology by adding several assets to its R&D pipeline. In partnership with Scorpion Therapeutics, PFL-241/STX-241 and PFL-721/STX-721, two mutant-selective EGFR inhibitors, will be developed for the treatment of EGFR-driven non-small cell lung cancer (NSCLC) patients. Through the acquisition of Vertical Bio, PFL-002/VERT-002 will undergo clinical testing in solid tumors driven by MET genetic alterations. More recently, the pan-RAF inhibitor exarafenib was acquired from Kinnate Biopharma with the aim to expand targeted therapy options for RAS/RAF-driven solid tumors. These new additions to its clinical development portfolio complement Pierre Fabre Laboratories' existing precision oncology portfolio targeting BRAF, MEK, HER2, with encorafenib, binimetinib and neratinib, respectively.

LOS ANGELES--(BUSINESS WIRE)-- Puma Biotechnology, Inc. (NASDAQ: PBYI), a biopharmaceutical company, announced the presentation of alisertib for the treatment of patients with advanced osimertinib-resistant epidermal growth factor receptor-mutated (EGFR-mutated) non-small cell lung cancer (NCT04085315) at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting currently being held in Chicago. The poster (Abstract #8572, Poster Bd #436), entitled, “A Phase I/Ib study of the aurora kinase A inhibitor alisertib in combination with osimertinib in advanced osimertinib-resistant EGFR-mutated lung cancer,” was presented by Turja Chakrabarti, MD., University of California, San Francisco, at the Lung Cancer – Non-Small Cell Metastatic Poster Session, on June 3 at 1:30 p.m. CDT. A copy of the poster is available on the Puma website. This open-label, single-center Phase I/Ib study enrolled 21 evaluable patients with stage IV EGFR-mutated NSCLC (EGFR driver mutation: 76.1% exon 19 deletion; 14.3% L858R; 9.5 % L861Q) who had progressed on osimertinib monotherapy. 47.6% of patients had previously received only first-line osimertinib monotherapy, while 52.3% had received two or greater prior lines of therapy. In the Phase I portion of the trial, 10 patients were treated in a 3+3 dose escalation phase with alisertib using an intermittent dosing strategy of 30 mg (n = 6) or 40 mg (n = 4) twice daily (BID) in combination with osimertinib 80 mg daily. Alisertib was added to osimertinib treatment at the time of disease progression on osimertinib. Intermittent alisertib 30 mg BID was identified as the MTD and RP2D in combination with osimertinib 80 mg daily. In the Phase Ib expansion portion of the trial, 11 additional patients were treated at the 30 mg alisertib BID intermittent dosing schedule in combination with osimertinib 80 mg daily with alisertib being added to osimertinib treatment at the time of disease progression on osimertinib. The most common treatment-related adverse events (AEs) (any grade) included neutropenia (42.9%), anemia (42.9%), diarrhea (38.1%), and lymphopenia (33.3%). Grade 3 or higher AEs neutropenia (4.8%), anemia (4.8%), diarrhea (14.3%), and lymphopenia (4.8%). For the 21 evaluable patients, the investigator assessed overall response rate was 9.5% (95% CI: 0 to 22%) and disease control rate was 81% (95% CI: 69% to 93%). The median PFS for all patients was 5.5 months, while the median OS was 23.5 months. For patients with TP53 mutations (n=9), the overall response rate was 0%, and the disease control rate was 66.7%. For patients who were tp53 wild type (n=8), the overall response rate was 25%, and the disease control rate was 87.5%. For patients with TP53 mutations, the progression free survival was 3.7 months, and for patients who were tp53 wild type, the progression free survival was 8.0 months (hazard ratio:0.42, p = 0.05). Dr. Collin M. Blakely, the lead principal investigator of the study and senior author of the presentation, from the University of California in San Francisco, said, “We are pleased with the initial results of the clinical trial and very interested in the cohort of patients who are tp53 wild type as tp53 is known to be involved in the aurora kinase pathway. We are modifying the protocol to limit further enrollment in the trial to patients who are tp53 wild type and we look forward to further studying this combination in this biomarker directed cohort of patients.” Alan H. Auerbach, Chief Executive Officer and President of Puma Biotechnology, said, “We are pleased to see the promising efficacy signals in the cohort of patients who are tp53 wild type. As tp53 is well known to be involved in the aurora kinase pathway, we are pleased to see the activity of alisertib when given in combination with osimertinib in this population of patients. We look forward to continuing to enroll this trial in this cohort of patients.” About Puma Biotechnology Puma Biotechnology, Inc. is a biopharmaceutical company with a focus on the development and commercialization of innovative products to enhance cancer care. Puma in-licensed the global development and commercialization rights to PB272 (neratinib, oral) in 2011. Neratinib, oral was approved by the U.S. Food and Drug Administration in 2017 for the extended adjuvant treatment of adult patients with early stage HER2-overexpressed/amplified breast cancer, following adjuvant trastuzumab-based therapy, and is marketed in the United States as NERLYNX® (neratinib) tablets. In February 2020, NERLYNX was also approved by the FDA in combination with capecitabine for the treatment of adult patients with advanced or metastatic HER2-positive breast cancer who have received two or more prior anti-HER2-based regimens in the metastatic setting. NERLYNX was granted marketing authorization by the European Commission in 2018 for the extended adjuvant treatment of adult patients with early stage hormone receptor-positive HER2-overexpressed/amplified breast cancer and who are less than one year from completion of prior adjuvant trastuzumab-based therapy. NERLYNX® is a registered trademark of Puma Biotechnology, Inc. In September 2022, Puma entered into an exclusive license agreement for the development and commercialization of the anti-cancer drug alisertib, an investigational, selective, small molecule, orally administered inhibitor of aurora kinase A. Initially, Puma intends to focus the development of alisertib on the treatment of small cell lung cancer and breast cancer. In February 2024, Puma initiated ALISCA-Lung 1, a Phase II clinical trial of alisertib monotherapy for the treatment of patients with extensive-stage small cell lung cancer.
