First approval for romosozumab

January 10, 2019 by Janice Reichert

Japan’s Ministry of Health, Labor and Welfare has granted a marketing authorization for romosozumab (EVENITY) for the treatment of osteoporosis in patients at high risk of fracture. Developed by Amgen and UCB, romosozumab is a humanized IgG2 monoclonal antibody that targets sclerostin. The approval in Japan is based on results from the Phase 3 FRAME and BRIDGE studies, which included 7,180 postmenopausal women with osteoporosis and 245 men with osteoporosis, respectively.

A biologics license application (BLA) for romosozumab as a treatment of osteoporosis in postmenopausal women at high risk for fracture was submitted to the U.S. Food and Drug Administration (FDA) in July 2016, but additional safety and efficacy data was requested in the FDA’s complete response letter, as announced by Amgen and UCB in July 2017. In July 2018, Amgen and UCB announced that the BLA had been resubmitted. In addition to data from early-stage clinical studies, the original BLA included data from the Phase 3 FRAME study. The resubmitted BLA includes results from the more recent Phase 3 ARCH study, an alendronate-active comparator trial including 4,093 postmenopausal women with osteoporosis who experienced a fracture, and the Phase 3 BRIDGE study. The FDA’s Bone, Reproductive and Urologic Drugs Advisory Committee is scheduled to review data supporting the BLA for romosozumab at a meeting on January 16, 2019.

The European Medicines Agency is also currently reviewing a marketing application for romosozumab.

“Antibodies to watch in 2019”

December 23, 2018 by Janice Reichert

The latest “Antibodies to watch” article is now freely accessible at mAbs! 

For the past 10 years, the annual ‘Antibodies to watch’ articles have provided updates on key events in the late-stage development of antibody therapeutics, such as first regulatory review or approval, that occurred in the year before publication or were anticipated to occur during the year of publication. To commemorate the 10th anniversary of the article series and to celebrate the 2018 Nobel Prizes in Chemistry and in Physiology or Medicine, which were given for work that is highly relevant to antibody therapeutics research and development, the scope of the data presented was expanded to include an overview of all commercial clinical development of antibody therapeutics and approval success rates for this class of molecules. The data indicate that: 1) antibody therapeutics are entering clinical study, and being approved, in record numbers; 2) the commercial pipeline is robust, with over 570 antibody therapeutics at various clinical phases, including 62 in late-stage clinical studies; and 3) Phase 1 to approval success rates are favorable, ranging from 17–25%, depending on the therapeutic area (cancer vs. non-cancer).

As of November 2018, a record number of antibodies (erenumab (Aimovig), fremanezumab (Ajovy), galcanezumab (Emgality), burosumab (Crysvita), lanadelumab (Takhzyro), caplacizumab (Cablivi), mogamulizumab (Poteligeo), moxetumomab pasudodox (Lumoxiti), cemiplimab (Libtayo), ibalizumab (Trogarzo), tildrakizumab (Ilumetri, Ilumya), emapalumab (Gamifant)) that treat a wide variety of diseases were granted a first approval in either the European Union (EU) or United States (US). Also as of November 2018, 4 antibody therapeutics (sacituzumab govitecan, ravulizumab, risankizumab, romosozumab) were being considered for their first marketing approval in the EU or US, and an additional 3 antibody therapeutics developed by Chinese companies (tislelizumab, sintilimab, camrelizumab) were in regulatory review in China. In addition, the data show that 3 product candidates (leronlimab, brolucizumab, polatuzumab vedotin) may enter regulatory review by the end of 2018, and at least 12 (eptinezumab, teprotumumab, crizanlizumab, satralizumab, tanezumab, isatuximab, spartalizumab, MOR208, oportuzumab monatox, TSR-042, enfortumab vedotin, ublituximab) may enter regulatory review in 2019. Notably, approximately half (18 of 33) of the late-stage pipeline of antibody therapeutics for cancer are immune checkpoint modulators or antibody-drug conjugates. Of these, 7 (tremelimumab, spartalizumab, BCD-100, omburtamab, mirvetuximab soravtansine, trastuzumab duocarmazine, and depatuxizumab mafodotin) are being evaluated in clinical studies with primary completion dates in late 2018 and in 2019, and are thus ‘antibodies to watch’. The Antibody Society looks forward to documenting progress made with these and other ‘antibodies to watch’ in the next installment of this article series.

Update: Data in “Antibodies to watch in 2019” is as of November 2018. As noted in the post below, risankizumab was approved by FDA on December 21, 2018, bringing the total number of antibody therapeutics approved in the EU or US during 2018 to 13.

First approval for ravulizumab

December 21, 2018 by Janice Reichert

On December 21, 2018, the US Food and Drug Administration approved Ultomiris (ravulizumab) injection for the treatment of adult patients with paroxysmal nocturnal hemoglobinuria (PNH), a rare and life-threatening blood disease characterized by hemolysis of red blood cells mediated by the complement system. Developed by Alexion Pharmaceuticals, ravulizumab is a humanized mAb that inhibits complement component 5 (C5). The biologics license application for ravulizumab received a Priority Review designation. In a Phase 3 study, ravulizumab demonstrated non-inferiority to Soliris® (anti-C5 eculizumab) in complement-inhibitor treatment-naïve patients with PNH. Also developed by Alexion Pharmaceuticals, Soliris® was first approved for PNH in 2007. Ravulizumab is also undergoing regulatory review in the EU. It was granted Orphan Drug designation in both the US and EU for the treatment of patients with PNH.

First approval for cemiplimab-rwlc

September 28, 2018 by Janice Reichert

On September 28, 2018, the U.S. Food and Drug Administration (FDA) approved cemiplimab-rwlc (Libtayo) for the treatment of patients with metastatic cutaneous squamous cell carcinoma (CSCC) or locally advanced CSCC who are not candidates for curative surgery or curative radiation. Cemiplimab-rwlc is the third antibody therapeutic targeting PD1 to be granted an FDA approval, but it is the first drug to be approved in the US specifically for advanced CSCC.

FDA’s approval of Libtayo was based on a combined analysis of data from an open-label, multi-center, non-randomized Phase 2 trial known as EMPOWER-CSCC-1 (Study 1540) and two advanced CSCC expansion cohorts from a multi-center, open-label, non-randomized Phase 1 trial (Study 1423). A total of 108 patients (75 with metastatic disease and 33 with locally-advanced disease) were included in the efficacy evaluation. The confirmed objective response rate for all patients treated with Libtayo was 47%. FDA granted cemiplimab Breakthrough Therapy Designation status for advanced CSCC in 2017, and the drug’s marketing application was granted a priority review.

The Antibody Society maintains a comprehensive table of approved mAb therapeutics and those in regulatory review in the EU or US. As of Sep 28, a total of 11 antibody therapeutics had been granted first approvals in either the US or EU in 2018, and marketing applications for another 5 that have not yet been approved in either the EU or US are undergoing review in these regions.

First approval for galcanezumab-gnlm

September 28, 2018 by Janice Reichert

On September 27, 2018, the U.S. Food and Drug Administration (FDA) approved galcanezumab-gnlm (Emgality) for the preventive treatment of migraine in adults. Emgality is the third antibody therapeutic approved by FDA in 2018 for this indication. As we reported in previous posts, Aimovig (erenumab-aooe) was approved on May 17, 2018 and Ajovy (fremanezumab-vfrm) was approved on September 14, 2018. The three products target either calcitonin gene-related peptide (CGRP) or the CGRP receptor. The recommended dosage of Emgality is 240 mg loading dose (administered as two consecutive injections of 120 mg each), followed by monthly doses of 120 mg.

The efficacy and safety of Emgality was demonstrated in two Phase 3 clinical trials in patients with episodic migraine (EVOLVE-1, EVOLVE-2) and one Phase 3 clinical trial in patients with chronic migraine (REGAIN). In all three studies, patients were randomized to receive once-monthly placebo, Emgality 120 mg after an initial loading dose of 240 mg, or Emgality 240 mg. In EVOLVE-1, the mean change from baseline (days) was -4.7 days (N=210) for Emgality 120 mg compared to -2.8 days (N=425) for placebo (p<0.001), while in EVOLVE-2, the mean change from baseline (days)was -4.3 days (N=226) for Emgality 120 mg compared to -2.3 days (N=450) for placebo (p<0.001). In the REGAIN study, the mean change from baseline (days) was -4.8 days (N=273) for Emgality 120 mg compared to -2.7 days (N=538) for placebo (p<0.001).

The Antibody Society maintains a comprehensive table of approved mAb therapeutics and those in regulatory review in the EU or US. As of Sep 28, a total of 10 antibody therapeutics had been granted first approvals in either the US or EU in 2018, and marketing applications for another 6 that have not yet been approved in either the EU or US are undergoing review in these regions. Please log in to access the table in either PDF or Excel formats, located in the Members Only section.
