Drug approvals and other regulatory updates are in focus in the biotech sector. The sector is also witnessing consolidation as M&A activities pick up.
Recap of the Week’s Most Important Stories:
Updates From Gilead: Gilead Sciences, Inc.’s GILD Kite announced that the European Commission (“EC”) approved its CAR T-cell therapy Tecartus (brexucabtagene autoleucel) for the treatment of relapsed or refractory (r/r) B-cell precursor acute lymphoblastic leukemia (ALL). Tecartus has been approved for this indication for adult patients 26 years of age and above.
The EC nod was supported by data from the phase I/II ZUMA-3 study of adult patients (≥18 years old) with relapsed or refractory ALL. The CHMP had earlier given a positive opinion on the same. Another cell therapy in Kite’s kitty is Yescarta. The latest approval marks Kite’s fourth indication in Europe for its two cell therapies and first in leukemia.
The company also announced positive new data from a post hoc subgroup analysis from the phase III TROPiCS-02 study evaluating the breast cancer drug Trodelvy (sacituzumab govitecan-hziy). The study evaluated Trodelvy versus comparator chemotherapies (physicians’ choice of chemotherapy, TPC) in patients with HR+/HER2- metastatic breast cancer who progressed on endocrine-based therapies and at least two chemotherapies.
The analysis examined progression-free survival (PFS) in the intention-to-treat population by HER2-immunohistochemistry (IHC) status. Results showed Trodelvy’s efficacy across HER2-low and IHC0 status in pre-treated metastatic breast cancer patients. Trodelvy improved median PFS vs. TPC in both HER2-low (IHC1+ and IHC2+/ISH-negative) and IHC0 groups.
Gilead currently carries a Zacks Rank #3 (Hold). You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.
Spero Surges on FDA Update: Spero Therapeutics SPRO surged after the company provided a positive update following the receipt of minutes from a recent Type A meeting with the FDA on its experimental candidate tebipenem HBr. The meeting was conducted to discuss the steps required to resubmit the new drug application (NDA) for tebipenem HBr to treat complicated urinary tract infection (cUTI), including pyelonephritis. Spero received a complete response letter (CRL) from the FDA in June 2022 for the same as the agency concluded that the data from phase III ADAPT-PO study were insufficient to support approval during the prior review cycle.
During the above-mentioned type A meeting, the FDA indicated that positive results from a single additional phase III study supported by confirmatory nonclinical evidence of efficacy could be sufficient to back the approval of tebipenem HBr for the treatment of cUTI, including pyelonephritis for a limited use indication. Spero also reached alignment with the FDA on key components of the proposed pivotal phase III study design, which may be the subject of a Special Protocol Assessment (SPA) request, to be confirmed once the clinical protocol is finalized.
