The sequence is quoted from: *****

In this phase 1, double-blind, parallel-group trial, 111 healthy male volunteers were randomized 1:1:1 to receive a single 6-mg/kg intravenous infusion of BP02, EU-trastuzumab, or US-trastuzumab and were evaluated for 78 days. Serum drug concentration-time data were analyzed by non-compartmental methods. The PK similarity of BP02 to the two reference products, and between EU-trastuzumab and US-trastuzumab, was determined using the standard 80-125% bioequivalence criteria.

RESULTS:

Baseline demographics for the 111 subjects with evaluable pharmacokinetics were similar across all treatment groups. PK profiles were similar for the three products. The 90% confidence intervals (CIs) for the ratios of area under the serum concentration-time curve (AUC) from the time of dosing to infinity (AUC_0-inf), AUC from the time of dosing until the time of the last quantifiable concentration (AUC_0-t), and peak serum concentration of trastuzumab (C_max) were within 80% to 125% for all three pairwise comparisons. Adverse events (AEs) were similar across all arms, with treatment-related AEs reported by 73.0%, 73.0%, and 89.2% of the subjects in the BP02, EU-trastuzumab, and US-trastuzumab groups, respectively. The most common AEs were headache, infusion-related reactions, and upper-respiratory-tract infections. Four subjects-three in the US-trastuzumab group and one in the BP02 group-discontinued the study due to AEs. All post-dose samples except for two tested negative for anti-drug antibodies.

CONCLUSION:

This study demonstrates the PK similarity among BP02, EU-trastuzumab, and US-trastuzumab. The safety and immunogenicity profiles observed for the three products in this study are consistent with previous reports for trastuzumab.

Efficacy and Safety of BP02 (Trastuzumab Biosimilar) in HER2-Positive Metastatic Breast Cancer: A Multicenter Phase III Study

BACKGROUND AND OBJECTIVE:

Trastuzumab targets human epidermal growth factor receptor 2 (HER2) receptors and is indicated for treating HER2-positive metastatic breast cancer. BP02, a recombinant IgG1 kappa humanized monoclonal antibody, is being developed as a trastuzumab biosimilar. The objective of this study was to evaluate the equivalence of BP02 with reference trastuzumab (RT: Herceptin^®-EU) in patients with HER2-positive metastatic breast cancer.

METHODS:

This double-blinded, 1:1 randomized, parallel-group, active-controlled, phase III equivalence trial recruited women aged 18-75 years with histologically/cytologically confirmed HER2- positive, locally recurrent or metastatic breast cancer with systemic metastasis, from 59 sites in India. Patients were randomly allocated 1:1 stratified by estrogen receptor/progesterone receptor status to receive BP02/RT (8-mg/kg loading dose on day 1-cycle 1, 6 mg/kg on day 1-cycles 2-8, of each 3-week cycle) combined with docetaxel (75 mg/m² on day 1-cycles 1-8) [induction phase]. Participants with complete or partial response, or stable disease at the end of the induction phase continued the study drug until disease progression/treatment discontinuation [maintenance phase]. The primary efficacy endpoint was the objective response rate per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.

RESULTS:

Between 23 September, 2020 and 16 September, 2022, 690 patients were recruited (n = 345 each to BP02/RT). At the end of the induction phase (intent-to-treat population), a similar proportion of patients achieved an objective response rate with BP02 (n = 231 [67.0%], 95% confidence interval [CI] 62.0, 71.9) and RT (n = 238 [69.0%], 95% CI 64.1, 73.9). The 95% CI of risk difference (-2.03, 95% CI -9.15, 5.09) and 90% CI of risk ratio (0.97, 90% CI 0.89, 1.06) were within equivalence margins of ± 13% and (0.80, 1.25), respectively. Treatment-emergent adverse events leading to treatment withdrawal were reported in 2.9% and 3.2% patients with BP02 and RT, respectively.

CONCLUSIONS:

BP02 showed an equivalent efficacy and similar safety profile to RT at the end of 24 weeks.

UK MHRA approves Aurobindo Pharma Cancer biosimilar Dazublys

Mumbai: Aurobindo Pharma biosimilars arm CuraTeQ Biologics Trastuzumab —a cancer therapy—biosimilar version ‘ Dazublys ’ has received marketing approval in the UK. Sharing the update with the stock exchange, Aurobindo disclosed that its trastuzumab biosimilar version, developed by the company’s wholly owned step-down subsidiary, CuraTeQ Biologics has obtained marketing authorisation from UK’s Medicines and Healthcare products Regulatory Agency (MHRA).' Dazublys is indicated for the treatment of adult patients with HER2-positive breast cancer and gastric cancer . As per the company, the drug was earlier approved by the European Union from the European Commission (EC) in July this year. With this approval CuraTeQ’s UK portfolio includes four biosimilars including Bevqolva —a VEGF targeting therapy approved for colorectal cancer, small cell lung cancer and several other indications. The other two drugs include Zefylti— a therapy to stimulate white blood cells in bone marrow; and Dyrupeg— a supportive therapy to reduce white blood cell loss, fever etc. By Online Bureau ,

Aurobindo Pharma arm CuraTeQ gets positive EMA opinion for biosimilar Zefylti

Hyderabad: Aurobindo Pharma ’s wholly-owned subsidiary, CuraTeQ Biologics Private Limited , received a positive opinion from the Committee for Medicinal Products for Human Use (CHMP) of the European drug regulatory body, the European Medicines Agency ( EMA ), for its filgrastim biosimilar , Zefylti. The committee recommended granting marketing authorisation. The Hyderabad-based company stated that Zefylti is its first biosimilar to receive a positive opinion from the EMA’s CHMP after it received the GMP (good manufacturing practices) certificate from the EMA in November this year. Zefylti, codenamed BP13, is intended for the treatment of neutropenia and the mobilisation of peripheral progenitor cells (PBPCs). It will be available in dosages of 30 MU per 0.5 mL and 48 MU per 0.5 mL. “Two more products, our biosimilar versions of pegylated filgrastim (BP14) and trastuzumab (BP02), are currently under review with the EMA, and a biosimilar to bevacizumab (BP01) is under review with the UK-MHRA. We are confident and on track to bring these treatment options to patients next year,” Aurobindo Pharma stated. The Hyderabad-headquartered CuraTeQ is a global biopharmaceutical company focused on developing biosimilars for the treatment of various cancers and autoimmune diseases. It currently has a pipeline of 14 biosimilars for the oncology and immunology segments. The company has end-to-end capabilities in producing a range of products, from bulk drug substances to fill-finish and packaged drug products. By Swati Bharadwaj ,
