| Data from RAGNAR, the largest tumor-agnostic study reported for a targeted therapy and the first to evaluate FGFR-driven malignancies, featured in oral presentation at the 2022 ASCO Annual Meeting CHICAGO, June 7, 2022 /PRNewswire/ -- The Janssen Pharmaceutical Companies of Johnson & Johnson today announced initial results from the pivotal Phase 2 RAGNAR study evaluating the investigational use of BALVERSA® (erdafitinib), a fibroblast growth factor receptor (FGFR) kinase inhibitor, in patients with advanced solid tumors with prespecified FGFR alterations. At a planned interim analysis (IA), responses were observed across a variety of FGFR-driven solid tumors for patients who had exhausted standard treatment options prior to being treated with BALVERSA®.1 These results will be featured in an oral presentation (Abstract #3007) today at the 2022 American Society of Clinical Oncology Annual Meeting. RAGNAR (NCT04083976) is a Phase 2 clinical study designed to evaluate the efficacy and safety of BALVERSA® in patients with advanced or metastatic solid tumors and prespecified FGFR gene alterations, regardless of tumor location or histology (tumor-agnostic). The IA was based on 178 patients with 32 distinct solid tumor histologies.1 Patients in the study were prospectively identified by local molecular testing or central next-generation sequencing (NGS); the most common tumor types were cholangiocarcinoma (bile duct cancer) (n=31), high-grade glioma (tumor of the brain or spinal cord) (n=29), breast cancer (n=14), pancreatic cancer (n=13) and squamous non-small cell lung cancer (n=11).1 The study also included tumors that occur less frequently in the real world such as salivary gland and parathyroid carcinomas (rare endocrine malignancies), as well as tumors of unknown primary origin.1 Study participants were heavily pretreated, with 74.7 percent (n=133) having received two or more prior lines of therapy.1 The primary endpoint of the RAGNAR study is the overall response rate (ORR) as assessed by an independent review committee (IRC). At the IA data cutoff, IRC assessed an ORR of 29.2 percent (95 percent confidence interval [CI], 22.7-36.5) and a disease control rate (DCR) of 72.5 percent (95 percent CI, 65.3-78.9) for the overall tumor-agnostic patient population.1 Investigators observed responses in 14 distinct tumor types. This included responses in hard-to-treat malignancies such as salivary gland cancer (100 percent ORR; treated n=5, responders n=5), pancreatic cancer (31 percent ORR; treated n=13, responders n=4) and glioblastoma (21 percent ORR; treated n=29, responders=6).1 Investigators also observed an overall 7.1-month median duration of response (DOR) (95 percent CI, 5.5-9.3)1. At the data cutoff, 51.1 percent (n=24) of patients who had responded to treatment continued to show a response.1 The primary analysis for all patients treated in this RAGNAR cohort, known as the broad panel cohort, is anticipated later this year. The safety profile of BALVERSA® observed in RAGNAR was consistent with the known safety profile of BALVERSA® in metastatic urothelial carcinoma (mUC). Across tumor types, 44.9 percent of patients experienced adverse events of grade three or above.1 Adverse events were manageable with supportive care and treatment interruptions or reductions, when necessary.1 The discontinuation rate due to drug-related adverse events was 7.3 percent.1 “Diagnostic advances in the identification of FGFR gene alterations have opened the door to targeted, tumor-agnostic treatment approaches for patients,” said Yohann Loriot, M.D., Ph.D., Institut Gustave Roussy and University of Paris-Saclay, and principal study investigator.‡ “Results from the RAGNAR study show that, through the targeted inhibition of FGFR receptors, we may be able to tailor treatment for patients with advanced FGFR-driven cancers, regardless of tumor location or histology.” In 2019, BALVERSA® was granted accelerated approval by the U.S. Food and Drug Administration (FDA) as a targeted therapy for adult patients with locally advanced or mUC with susceptible FGFR2 or FGFR3 alterations and who have progressed during or following at least one line of prior platinum-containing chemotherapy, including within 12 months of neoadjuvant or adjuvant platinum-containing chemotherapy.2 “Janssen is committed to advancing precision medicine approaches for the treatment of patients with biomarker-driven cancers, an area of clear unmet need,” said Kiran Patel, M.D., Vice President, Clinical Development, Solid Tumors, Janssen Research & Development, LLC. “RAGNAR, Janssen’s first tumor-agnostic study, demonstrates our commitment to understand the biology of disease, identify new treatment pathways and improve patient outcomes. We look forward to progressing the development of BALVERSA for these patients and sharing additional updates on this program in the future.” About FGFR Alterations About the RAGNAR Study The primary endpoint of RAGNAR is IRC-assessed ORR. Key secondary endpoints include investigator-assessed ORR, DOR, DCR, clinical benefit rate, progression free survival, overall survival and incidence and severity of adverse events. About BALVERSA® In addition to RAGNAR, BALVERSA® is being studied in clinical trials including the Phase 3 THOR (NCT03390504) study evaluating BALVERSA® versus standard of care, consisting of chemotherapy (docetaxel or vinflunine) or anti-PD-1 agent pembrolizumab, in participants with advanced urothelial cancer and selected FGFR aberrations with disease progression following one or two prior lines of therapy; and the randomized Phase 2 THOR-2 (NCT04172675) study examining BALVERSA® versus investigator choice of intravesical chemotherapy in participants who received Bacillus Calmette-Guérin and recurred with high risk non-muscle-invasive bladder cancer.7,8 In 2008, Janssen Pharmaceutica NV entered into an exclusive worldwide license and collaboration agreement with Astex Pharmaceuticals to develop and commercialize BALVERSA®.

BALVERSA® IMPORTANT SAFETY INFORMATION Warnings and Precautions CSR/RPED was reported in 25% of patients treated with BALVERSA®, with a median time to first onset of 50 days. Grade 3 CSR/RPED, involving central field of vision, was reported in 3% of patients. CSR/RPED resolved in 13% of patients and was ongoing in 13% of patients at the study cutoff. CSR/RPED led to dose interruptions and reductions in 9% and 14% of patients, respectively, and 3% of patients discontinued BALVERSA®. Dry eye symptoms occurred in 28% of patients during treatment with BALVERSA® and were Grade 3 in 6% of patients. All patients should receive dry eye prophylaxis with ocular demulcents as needed. Perform monthly ophthalmological examinations during the first 4 months of treatment and every 3 months afterwards, and urgently at any time for visual symptoms. Ophthalmological examination should include assessment of visual acuity, slit lamp examination, fundoscopy, and optical coherence tomography. Withhold BALVERSA® when CSR occurs and permanently discontinue if it does not resolve within 4 weeks or if Grade 4 in severity. For ocular adverse reactions, follow the dose modification guidelines [see Dosage and Administration (2.3)]. Hyperphosphatemia and Soft Tissue Mineralization – BALVERSA® can cause hyperphosphatemia leading to soft tissue mineralization, cutaneous calcinosis, non-uremic calciphylaxis and vascular calcification. Increases in phosphate levels are a pharmacodynamic effect of BALVERSA® [see Pharmacodynamics (12.2)]. Hyperphosphatemia was reported as adverse reaction in 76% of patients treated with BALVERSA®. The median onset time for any grade event of hyperphosphatemia was 20 days (range: 8–116) after initiating BALVERSA®. Thirty-two percent of patients received phosphate binders during treatment with BALVERSA®. Cutaneous calcinosis, non-uremic calciphylaxis and vascular calcification have been observed in 0.3% of patients treated with BALVERSA®. Monitor for hyperphosphatemia throughout treatment. In all patients, restrict phosphate intake to 600-800 mg daily. If serum phosphate is above 7.0 mg/dL, consider adding an oral phosphate binder until serum phosphate level returns to <5.5 mg/dL. Withhold, dose reduce, or permanently discontinue BALVERSA® based on duration and severity of hyperphosphatemia [see Dosage and Administration (2.3), Table 2: Dose Modifications for Adverse Reactions]. Embryo-fetal Toxicity – Based on the mechanism of action and findings in animal reproduction studies, BALVERSA® can cause fetal harm when administered to a pregnant woman. In a rat embryo-fetal toxicity study, erdafitinib was embryotoxic and teratogenic at exposures less than the human exposures at all doses studied. Advise pregnant women of the potential risk to the fetus. Advise female patients of reproductive potential to use effective contraception during treatment with BALVERSA® and for one month after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with BALVERSA® and for one month after the last dose [see Use in Specific Populations (8.1, 8.3) and Clinical Pharmacology (12.1)]. Most common adverse reactions including laboratory abnormalities ≥20%: *Included within onycholysis. †Included within dry eye.
