Tisotumab vedotin approved by FDA for cervical cancer

September 21, 2021 by Janice Reichert

On September 20, 2021, FDA granted accelerated approval to TIVDAK (tisotumab vedotin-tftv) for the treatment of adult patients with recurrent or metastatic cervical cancer with disease progression on or after chemotherapy. The BLA for TIVDAK for this indication was given a Priority review. TIVDAK’s approval was based on tumor response and the durability of the response; verification and description of clinical benefit in confirmatory trials may be necessary for continued approval for this indication.

TIVDAK is an ADC comprising Genmab’s human tissue factor IgG1k antibody targeting tissue factor conjugated to MMAE via a protease-cleavable linker using Seagen’s ADC technology. The companies are co-developing the product. The recommended dose of TIVDAK is 2 mg/kg (up to a maximum of 200 mg) given as an intravenous infusion over 30 minutes every 3 weeks until disease progression or unacceptable toxicity.

FDA’s approval was based on results of the pivotal single-arm Phase 2 innovaTV 204 study (NCT03438396), which included 101 patients with recurrent or metastatic cervical cancer who had received no more than two prior systemic regimens in the recurrent or metastatic setting, including at least one prior platinum-based chemotherapy regimen. Patients received tisotumab vedotin 2.0 mg/kg IV every 3 weeks  until progression or toxicity. The major efficacy outcome measures were confirmed objective response rate as assessed by an independent review committee using RECIST v1.1 criteria and duration of response (DOR). The objective response rate was 24% [95% CI: 15.9%-33.3%], including 7 patients (7%) with a complete response and 17 patients (17%) with a partial response, and the median DOR was 8.3 months (95% CI: 4.2, not reached).

TIVDAK is the 9th antibody therapeutic to be first approved for marketing in the EU or US in 2021. Explore our searchable table of antibody therapeutics approved in the US or EU for details.

FDA grants first approval to belantamab mafodotin-blmf

August 7, 2020 by Janice Reichert

On August 5, 2020, the U.S. Food and Drug Administration (FDA) approved belantamab mafodotin-blmf (BLENREP) for the treatment of adult patients with relapsed or refractory multiple myeloma who have received at least 4 prior therapies including an anti-CD38 monoclonal antibody, a proteasome inhibitor, and an immunomodulatory agent. BLENREP was granted an accelerated approval for this indication based on response rate. Further adequate and well-controlled studies/clinical trials must be done to verify and describe clinical benefit.

Belantamab mafodotin-blmf is an antibody-drug conjugate (ADC) composed of a humanized IgG1 monoclonal antibody and the cytotoxic agent maleimidocaproyl monomethyl auristatin F. The ADC binds to B-cell maturation antigen found on myeloma cell surfaces and is internalized. In the cell, the cytotoxic agent is released and kills the cells.

Belantamab mafodotin-blmf was evaluated in the Phase 2 DREAMM-2 (NCT03525678), an open-label, multicenter trial. Efficacy was based on overall response rate (ORR) and response duration. In patients receiving the recommended dose of 2.5 mg/kg, the ORR was 31% (97.5% CI: 21%, 43%) 73% of responders had response durations ≥6 months. Detailed results of the study were published in The Lancet Oncology in February 2020.

On July 24, 2020, the European Medicines Agency’s (EMA) human medicines committee recommended granting a conditional marketing authorization in the European Union for Blenrep (belantamab mafodotin) to treat adult patients with relapsed and refractory multiple myeloma who no longer respond to treatment with an immunomodulatory agent, a proteasome inhibitor and a CD-38 monoclonal antibody. Blenrep was accepted in EMA’s PRIME scheme, and it was designated as an orphan medicinal product. EMA recommended a conditional marketing authorization, and this opinion was sent to the European Commission for the adoption of a decision on an EU-wide marketing authorization.

Antibodies to watch

Belantamab mafodotin-blmf is the 7th antibody therapeutic to be granted a first approval in the US or EU in 2020. The Antibody Society maintains a comprehensive table of approved monoclonal antibody therapeutics and those in regulatory review in the EU or US. The table, which is located in the Web Resources section of the Society’s website, can be downloaded in Excel format. Information about antibody therapeutics approved outside the US or EU can be found in the table notes.

Information about other antibody therapeutics that may enter regulatory review in 2020 can be found in ‘Antibodies to watch in 2020’.

FDA approves sacituzumab govitecan (Trodelvy®) for triple-negative breast cancer

April 22, 2020 by Janice Reichert

On April 22, 2020, the US Food and Drug Administration (FDA) granted an accelerated approval to Trodelvy® (sacituzumab govitecan-hziy) for the treatment of patients with metastatic triple-negative breast cancer who received at least two prior treatments for metastatic disease. Sacituzumab govitecan is composed of an anti-TROP-2 humanized IgG1 antibody conjugated to the topoisomerase inhibitor SN38, which is the active metabolite of irinotecan.

The approval was based on the results of a clinical trial of 108 patients with metastatic triple-negative breast cancer who had received at least two prior treatments for metastatic disease. In this study, the overall response rate was 33.3%, with a median duration of response of 7.7 months. Of the patients who responded to treatment, 55.6% maintained their response for 6 or more months and 16.7% maintained their response for 12 or more months.

The accelerated approval program allows FDA to approve drugs for serious conditions to fill an unmet medical need based on a surrogate endpoint, i.e., a result that is reasonably likely to predict a clinical benefit to patients. Additional clinical trials are required to confirm Trodelvy’s clinical benefit, and the FDA can remove the drug from the market if the confirmatory trial does not show that the drug provides clinical benefit.

Good and bad news for antibody-drug conjugates

September 3, 2019 by Janice Reichert

On August 23, 2019 GlaxoSmithKline announced positive headline results from the pivotal DREAMM-2 study of the antibody-drug conjugate belantamab mafodotin (GSK2857916) for multiple myeloma. The two-arm study met its primary objective and demonstrated a clinically meaningful overall response rate with belantamab mafodotin in the patient population. The safety and tolerability profile was consistent with that observed in DREAMM-1, the first time in human study of belantamab mafodotin. Data from the DREAMM-2 study will be the basis for regulatory filings starting later this year.

•             Belantamab mafodotin is a humanized anti-B-cell maturation antigen monoclonal antibody that is afucosylated and conjugated to the microtubule-disrupting agent monomethyl auristatin-F.

On August 29, 2019 AbbVie announced that MERU (NCT03033511), a Phase 3 trial evaluating the antibody-drug conjugate rovalpituzumab tesirine (Rova-T) as a first-line maintenance therapy for advanced small-cell lung cancer, demonstrated no survival benefit at a pre-planned interim analysis for patients receiving Rova-T as compared with placebo. The overall safety profile was generally consistent with that observed in previous studies. The MERU trial is being closed, and the Rova-T research and development program has been terminated. AbbVie will move forward prioritizing other development programs within its oncology pipeline.

•             Rovalpituzumab tesirine is an antibody-drug conjugate composed of a humanized monoclonal antibody, dipeptide linker, and pyrrolobenzodiazepine dimer toxin with a drug-to-antibody ratio of 2. The antibody component targets cancer-stem cell-associated delta-like protein 3.
