RARITAN, N.J. - The Janssen Pharmaceutical Companies of Johnson & Johnson announced results from the Phase 1b/2 NORSE (NCT03473743) study evaluating BALVERSA (erdafitinib) in combination with cetrelimab, an anti-programmed cell death protein 1 (PD-1) monoclonal antibody, compared to BALVERSA monotherapy in patients with locally advanced or metastatic urothelial carcinoma (mUC) with fibroblast growth factor receptor (FGFR)3 or FGFR2 genetic alterations who are ineligible for cisplatin, a current standard of care treatment for mUC. The results were highlighted in an oral presentation at the European Society for Medical Oncology (ESMO) Annual Congress 2021 virtual meeting on Friday, September 17 (Abstract #LBA 27).1

Preliminary findings suggest robust clinical activity and depth of response in patients treated with BALVERSA in combination with cetrelimab.1 The overall safety of treatment with BALVERSA in combination with cetrelimab was generally consistent with BALVERSA monotherapy and aligned with the known safety profile of approved anti-PD-1 therapies.1 At the time of analysis, the investigator-assessed objective response rate (ORR) in 19 patients treated with BALVERSA in combination with cetrelimab was 68 percent (95 percent confidence interval [CI]; 43-87), of which 21 percent (n=4) were complete responses (CR) and 47 percent were partial responses (PR).1 The disease control rate (DCR) was 90 percent (95 percent CI; 67-99) for evaluable patients using the Response Evaluation Criteria in Solid Tumors Version 1.1* (RECIST v1.1) criteria.1 The ORR in 18 patients treated with BALVERSA monotherapy was 33 percent (95 percent CI; 13-59), in which one patient showed a CR and 28 percent (n=5) were partial responses. The DCR was 100 percent (95 percent CI; 82-100).1

'PD-1 inhibitors have become treatment options for many types of solid tumors, including bladder cancer. Now, as we learn more about the genetic factors that impact treatment outcomes, we are exploring new treatment approaches that may help patients with specific mutations, including FGFR-alterations and fusions,' said Thomas Powles, MRCP, M.D., Professor of Uro-Oncology, Director of Barts Cancer Institute, London and principal study investigator.(+) 'With this combination of erdafitinib and cetrelimab, we aim to change the tumor microenvironment to make it more receptive to PD-1 intervention.'

Fibroblast growth factor receptors are a family of receptor tyrosine kinases that can be activated by genetic alterations in a variety of tumor types, potentially leading to increased tumor cell growth and survival.2 Approximately 20 percent of patients diagnosed with mUC have an FGFR genetic alteration.3,4 A current standard of care for mUC is cisplatin-based chemotherapy, however, more than 50 percent of patients with mUC may be ineligible for cisplatin treatment, underscoring a need for new treatment options.5 Alternative options for patients with newly diagnosed mUC include different chemotherapy regimens or PD-1 inhibitors, which enhance T-cell immune responses against the tumor cells.6

The findings presented at ESMO build upon the growing set of BALVERSA data. In 2019 the U.S. Food and Drug Administration (FDA) granted accelerated approval to BALVERSA, with a companion diagnostic, as a once-daily oral FGFR kinase inhibitor for patients with mUC that have susceptible FGFR3 and FGFR2 genetic 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. This indication is approved under accelerated approval based on tumor response rate. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.7

The safety profile of BALVERSA in combination with cetrelimab (n=24) was generally similar to that of BALVERSA monotherapy (n=24), with the most common treatment-emergent adverse events (AEs) being hyperphosphatemia (BALVERSA in combination with cetrelimab vs BALVERSA monotherapy, 58 percent vs 58 percent), stomatitis (54 percent vs 63 percent), diarrhea (42 percent vs 50 percent), dry mouth (58 percent vs 21 percent), dry skin (38 percent vs 21 percent) and anemia (25 percent vs 25 percent).1 Grade 3-4 AEs occurred in 12 patients (50 percent) in the BALVERSA in combination with cetrelimab arm and 9 patients (38 percent) in the BALVERSA arm.1 In the BALVERSA in combination with cetrelimab arm, the most frequent Grade 3-4 AEs were stomatitis (n=3 [12.5 percent]), lipase increased (n=3 [12.5 percent]), and fatigue (n=2 [8.3 percent]); in the BALVERSA arm, these were anemia (n=3 patients [12.5 percent]) and general physical health deterioration (n=3 [12.5 percent]).1

'As the first targeted treatment approved for patients with locally advanced or metastatic bladder cancer and FGFR3 or FGFR2 genetic alterations after platinum-based chemotherapy, we are encouraged by the data that continue to support the safety and efficacy of BALVERSA and its benefit for these patients with high unmet medical need. By investigating two active classes of drugs with BALVERSA and cetrelimab, our aim is to maximize the potential benefits of this combination approach for these patients,' said Craig Tendler, M.D., Vice President, Late Development and Global Medical Affairs, Oncology, Janssen Research & Development, LLC. 'The continued development of BALVERSA reflects Janssen's ongoing commitment to offer more personalized therapy approaches for patients with bladder cancer, a disease where there is considerable need for more effective treatment using innovative approaches.'

RECIST (version 1.1) refers to Response Evaluation Criteria in Solid Tumors, which is a standard way to measure how well solid tumors respond to treatment and is based on whether tumors shrink, remain the same or increase in size.8

About the NORSE Study9

NORSE (NCT03473743) is an open-label, Phase 1b/2 multicenter study of BALVERSA in combination with cetrelimab in patients with locally advanced or metastatic urothelial cancer and FGFR3 or FGFR2 gene alterations. Participants enrolled in Phase 1b may have received any number of lines of prior therapy, and participants enrolled in Phase 2 had no prior systemic therapy for metastatic disease and are ineligible for cisplatin-based chemotherapy, currently the standard of care. Phase 1b established the recommended Phase 2 dose (RP2D) for BALVERSA in combination with cetrelimab, and Phase 2 evaluates the safety and efficacy of the RP2D. The study is being conducted in three phases: screening phase, treatment phase and follow-up phase. Study evaluations include efficacy, pharmacokinetics, pharmacodynamics, immunogenicity, biomarkers and safety. Enrollment of the Phase 2 part of the NORSE study is currently ongoing.

About Urothelial Carcinoma

Urothelial carcinoma, also known as transitional cell carcinoma, starts in the innermost lining of the bladder.10 It is the most common and frequent form of bladder cancer, representing more than 90 percent of all bladder cancers.11 Approximately one in five patients (20 percent) diagnosed with mUC have an FGFR genetic alteration.4,5 Fibroblast growth factor receptors are a family of receptor tyrosine kinases that can be activated by genetic alterations in a variety of tumor types, and these alterations may lead to increased tumor cell growth and survival.3 In the U.S. each year, it is estimated that up to 3,000 people with urothelial carcinoma will test positive for FGFR genetic alterations.8,9,12,13 Fibroblast growth factor receptor genetic alterations can be detected through an FDA-approved companion diagnostic. The five-year survival rate for patients with Stage IV metastatic bladder cancer that has spread to distant parts of the body is currently 6 percent.14
