Genmab Announces Very Favorable Topline Results from Phase 2 Clinical Trial of Tisotumab Vedotin in Recurrent or Metastatic Cervical Cancer

​

Company Announcement

​

​

Copenhagen, Denmark; June 29, 2020 – Genmab A/S (Nasdaq: GMAB) today announced very favorable topline results from the Phase 2 single-arm clinical trial known as innovaTV 204 evaluating tisotumab vedotin administered every three weeks for the treatment of patients who have relapsed or progressed on or after prior treatment for recurrent or metastatic cervical cancer. Results from the trial showed a 24 percent confirmed objective response rate (ORR) by independent central review (95% Confidence Interval: 15.9% - 33.3%) with a median duration of response (DOR) of 8.3 months. The most common treatment-related adverse events (greater than or equal to 20 percent) included alopecia, epistaxis (nose bleeds), nausea, conjunctivitis, fatigue and dry eye. The data will be submitted for presentation at an upcoming medical meeting.

​

Tisotumab vedotin is an investigational antibody-drug conjugate (ADC) directed to tissue factor, which is expressed on cervical cancer and can promote tumor growth, angiogenesis and metastases.¹ Standard therapies for previously treated recurrent and/or metastatic cervical cancer generally result in limited objective response rates of typically less than 15 percent with median overall survival ranging from 6.0 to 9.4 months, in an all-comers population.^1-8 Tisotumab vedotin is being developed in collaboration with Seattle Genetics.

​

“After treatment with first-line chemotherapy regimens, there is a high unmet need for new effective and tolerable treatment options for women with advanced cervical cancer, regardless of biomarkers and histology,” said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab. “These promising topline data from innovaTV 204 will be the basis of further engagement with the U.S. FDA as we continue to progress and expand our tisotumab vedotin development program in solid tumors with our partner.”

​

Additional clinical trials of tisotumab vedotin are currently enrolling patients, including in combination with pembrolizumab, carboplatin or bevacizumab, and with a weekly dosing schedule in patients with locally advanced or metastatic cervical cancer. Tisotumab vedotin is also being evaluated in other tissue factor expressing tumor types, including ovarian and other solid tumors.

​

About innovaTV 204 Trial

The innovaTV 204 trial (also known as GCT1015-04 or innovaTV 204/GOG-3023/ENGOT-cx6) is an ongoing single-arm, global, multicenter study of tisotumab vedotin for patients with recurrent or metastatic cervical cancer who were previously treated with doublet chemotherapy with bevacizumab if eligible per local standards. Additionally, patients were eligible if they had received up to two prior lines of therapy in the metastatic setting. In the study operationalized by Genmab, 101 patients were treated with tisotumab vedotin at multiple centers in the U.S. and Europe. The primary endpoint of the trial was confirmed objective response rate per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 as assessed by independent central review. Key secondary endpoints included duration of response, progression-free survival, overall survival, safety and tolerability.

​

The study was conducted by Genmab in collaboration with Seattle Genetics Inc., European Network of Gynaecological Oncological Trial Groups (ENGOT) and Gynecologic Oncology Group (GOG).

About Cervical Cancer

Cervical cancer originates in the cells lining the cervix. Over 13,500 women are expected to be diagnosed with invasive cervical cancer in the U.S. in 2020, with approximately 4,200 deaths.⁹ Cervical cancer remains one of the leading causes of cancer death in women globally, with over 311,000 women dying annually; the vast majority of these women being in the developing world.¹⁰ Routine medical examinations and the human papillomavirus (HPV) vaccine have lowered the incidence of cervical cancer in the developed world. Despite these advances, women are still diagnosed with cervical cancer, which often recurs or becomes metastatic.

​

About Tisotumab Vedotin

Tisotumab vedotin is an investigational antibody-drug conjugate (ADC) composed of Genmab’s fully human monoclonal antibody specific for tissue factor and Seattle Genetics’ ADC technology that utilizes a protease-cleavable linker that covalently attaches the microtubule-disrupting agent monomethyl auristatin E (MMAE) to the antibody and releases it upon internalization, inducing target cell death. In cancer biology, tissue factor is a protein that can promote tumor growth, angiogenesis and metastases.¹ Based on its high expression on many solid tumors and its rapid internalization, tissue factor was selected as a target for an ADC approach. Tisotumab vedotin is being co-developed by Genmab and Seattle Genetics, under an agreement in which the companies share all costs and profits for the product on a 50:50 basis.

​

Tisotumab vedotin is being evaluated in ongoing clinical trials as monotherapy in a range of solid tumors, including recurrent and/or metastatic cervical cancer, ovarian cancer and in combination with other commonly used therapies in recurrent or metastatic cervical cancer. These trials are evaluating tisotumab vedotin on a weekly or every three weeks dosing schedule.

About Genmab

Genmab is a publicly traded, international biotechnology company specializing in the creation and development of differentiated antibody therapeutics for the treatment of cancer. Founded in 1999, the company is the creator of three approved antibodies: DARZALEX^® (daratumumab, under agreement with Janssen Biotech, Inc.) for the treatment of certain multiple myeloma indications in territories including the U.S., Europe and Japan, Arzerra^® (ofatumumab, under agreement with Novartis AG), for the treatment of certain chronic lymphocytic leukemia indications in the U.S., Japan and certain other territories and TEPEZZA™ (teprotumumab, under agreement with Roche granting sublicense to Horizon Therapeutics plc) for the treatment of thyroid eye disease in the U.S. A subcutaneous formulation of daratumumab, known as DARZALEX FASPRO™ (daratumumab and hyaluronidase-fihj) in the U.S., has been approved in the U.S. and Europe for the treatment of adult patients with certain multiple myeloma indications. Daratumumab is in clinical development by Janssen for the treatment of additional multiple myeloma indications, other blood cancers and amyloidosis. A subcutaneous formulation of ofatumumab is in development by Novartis for the treatment of relapsing multiple sclerosis. Genmab also has a broad clinical and pre-clinical product pipeline. Genmab's technology base consists of validated and proprietary next generation antibody technologies - the DuoBody^® platform for generation of bispecific antibodies, the HexaBody^® platform, which creates effector function enhanced antibodies, the HexElect^® platform, which combines two co-dependently acting HexaBody molecules to introduce selectivity while maximizing therapeutic potency and the DuoHexaBody^® platform, which enhances the potential potency of bispecific antibodies through hexamerization. The company intends to leverage these technologies to create opportunities for full or co-ownership of future products. Genmab has alliances with top tier pharmaceutical and biotechnology companies. Genmab is headquartered in Copenhagen, Denmark with sites in Utrecht, the Netherlands, Princeton, New Jersey, U.S. and Tokyo, Japan.
