Libtayo® (cemiplimab) Approved in Japan for Advanced or Recurrent Cervical Cancer
TARRYTOWN, N.Y., Dec. 23, 2022 /PRNewswire/ -- Regeneron Pharmaceuticals (NASDAQ: REGN) today announced that the Ministry of Health, Labor and Welfare (MHLW) in Japan has granted marketing and manufacturing authorization for Libtayo® (cemiplimab) as monotherapy to treat patients with advanced or recurrent cervical cancer whose disease progressed after chemotherapy.
“In recent years, the incidence of cervical cancer has increased in Japan, with the prognosis for advanced stage disease remaining poor and treatment options limited,” said Israel Lowy, M.D., Ph.D., Senior Vice President, Translational and Clinical Sciences, Oncology at Regeneron. “With this approval, Libtayo becomes the first single-agent immunotherapy approved in Japan for the treatment of advanced cervical cancer.”
The MHLW approval is based on positive data from the international, multicenter Phase 3 EMPOWER-Cervical 1 trial, conducted in collaboration with NRG Oncology-Japan, the GOG Foundation, Inc., and the European Network for Gynaecological Oncological Trial (ENGOT) groups. The trial evaluated Libtayo compared to an investigator’s choice of chemotherapy and enrolled 608 patients across 14 countries, including Japan, irrespective of PD-L1 expression status or histology. In March 2021, the trial was stopped early based on the highly significant effect of Libtayo on overall survival among squamous cell carcinoma patients following a unanimous recommendation by the Independent Data Monitoring Committee.
“With Libtayo, Japan now has an approved treatment option that has demonstrated significant survival benefits in this cervical cancer patient population compared to chemotherapy irrespective of PD-L1 expression – a milestone no other PD-1 inhibitor has achieved in a Phase 3 trial,” said Prof. Kosei Hasegawa, Gynecologic Oncology, Saitama Medical University International medical Center, a trial investigator and a member of NRG Oncology-Japan. “We are proud to have contributed to bringing this new treatment option to women living with this difficult-to-treat cancer in Japan.
Cervical cancer is the fourth leading cause of cancer death in women worldwide and is most frequently diagnosed in women between the ages of 35 and 44. Almost all cases of cervical cancer are caused by human papillomavirus (HPV) infection. It is estimated that approximately 600,000 new cases of cervical cancer are diagnosed and 350,000 deaths from cervical cancer occur worldwide each year.
In November 2022, Libtayo was approved by the European Commission for the treatment of adult patients with recurrent or metastatic cervical cancer and disease progression on or after platinum-based chemotherapy.
Libtayo is a fully human monoclonal antibody targeting the immune checkpoint receptor PD-1 on T cells and was invented using Regeneron’s proprietary VelocImmune® technology. By binding to PD-1, Libtayo has been shown to block cancer cells from using the PD-1 pathway to suppress T-cell activation. In the U.S. and other countries Libtayo is indicated in certain patients with advanced basal cell carcinoma (BCC), advanced CSCC and advanced non-small cell lung cancer (NSCLC), as well as in advanced cervical cancer in Japan, the European Union, Canada and Brazil.
Libtayo was jointly developed by Sanofi and Regeneron under a global collaboration agreement. As of July 1, 2022, Regeneron is responsible for the development and marketing of Libtayo globally. In Japan, Libtayo is currently marketed by Sanofi on Regeneron’s behalf over the course of a defined transition period.
The extensive clinical program for Libtayo is focused on difficult-to-treat cancers. Libtayo is currently being investigated in trials as a monotherapy, as well as in combination with either conventional or novel therapeutic approaches for other solid tumors and blood cancers. These potential uses are investigational, and their safety and efficacy have not been evaluated by any regulatory authority.
U.S. FDA-approved Indications
Libtayo is a prescription medicine used to treat:
-- People with a type of skin cancer called CSCC that has spread or cannot be cured by surgery or radiation.
-- People with a type of skin cancer called BCC:
- That cannot be removed by surgery (locally advanced BCC) and have received treatment with a hedgehog pathway inhibitor (HHI), or cannot receive treatment with an HHI.
- That has spread (metastatic BCC) and have received treatment with an HHI, or cannot receive treatment with an HHI. This use is approved based on how many patients responded to treatment and how long they responded. Studies are ongoing to provide additional information about clinical benefit.
-- Adults with a type of lung cancer called NSCLC:
- Libtayo may be used in combination with chemotherapy that contains a platinum medicine as your first treatment when your lung cancer has not spread outside your chest (locally advanced lung cancer) and you cannot have surgery or chemotherapy with radiation, OR your lung cancer has spread to other areas of your body (metastatic lung cancer), AND your tumor does not have an abnormal “EGFR”, “ALK” or “ROS1” gene.
- Libtayo may be used alone as your first treatment when your lung cancer has not spread outside your chest (locally advanced lung cancer) and you cannot have surgery or chemotherapy with radiation, OR your lung cancer has spread to other areas of your body (metastatic lung cancer), AND your tumor tests positive for high “PD-L1”, AND your tumor does not have an abnormal “EGFR”, “ALK “or “ROS1” gene.
It is not known if Libtayo is safe and effective in children.
IMPORTANT SAFETY INFORMATION FOR U.S. PATIENTS
What is the most important information I should know about Libtayo?
Libtayo is a medicine that may treat certain cancers by working with your immune system. Libtayo can cause your immune system to attack normal organs and tissues in any area of your body and can affect the way they work. These problems can sometimes become severe or life-threatening and can lead to death. You can have more than one of these problems at the same time. These problems may happen anytime during treatment or even after your treatment has ended.
Call or see your healthcare provider right away if you develop any new or worsening signs or symptoms, including:
- Lung problems: cough, shortness of breath, or chest pain
- Intestinal problems: diarrhea (loose stools) or more frequent bowel movements than usual, stools that are black, tarry, sticky or have blood or mucus, or severe stomach area (abdomen) pain or tenderness
- Liver problems: yellowing of your skin or the whites of your eyes, severe nausea or vomiting, pain on the right side of your stomach area (abdomen), dark urine (tea colored), or bleeding or bruising more easily than normal
- Hormone gland problems: headache that will not go away or unusual headaches, eye sensitivity to light, eye problems, rapid heartbeat, increased sweating, extreme tiredness, weight gain or weight loss, feeling more hungry or thirsty than usual, urinating more often than usual, hair loss, feeling cold, constipation, your voice gets deeper, dizziness or fainting, or changes in mood or behavior, such as decreased sex drive, irritability, or forgetfulness
- Kidney problems: decrease in your amount of urine, blood in your urine, swelling of your ankles, or loss of appetite
- Skin problems: rash, itching, skin blistering or peeling, painful sores or ulcers in mouth or nose, throat, or genital area, fever or flu-like symptoms, or swollen lymph nodes
- Problems can also happen in other organs and tissues. These are not all of the signs and symptoms of immune system problems that can happen with Libtayo. Call or see your healthcare provider right away for any new or worsening signs or symptoms, which may include: chest pain, irregular heartbeat, shortness of breath or swelling of ankles, confusion, sleepiness, memory problems, changes in mood or behavior, stiff neck, balance problems, tingling or numbness of the arms or legs, double vision, blurry vision, sensitivity to light, eye pain, changes in eyesight, persistent or severe muscle pain or weakness, muscle cramps, low red blood cells, or bruising
- Infusion reactions that can sometimes be severe. Signs and symptoms of infusion reactions may include: nausea, chills or shaking, itching or rash, flushing, shortness of breath or wheezing, dizziness, feel like passing out, fever, back or neck pain, or facial swelling
- Rejection of a transplanted organ. Your healthcare provider should tell you what signs and symptoms you should report and monitor you, depending on the type of organ transplant that you have had
- Complications, including graft-versus-host disease (GVHD), in people who have received a bone marrow (stem cell) transplant that uses donor stem cells (allogeneic). These complications can be serious and can lead to death. These complications may happen if you underwent transplantation either before or after being treated with Libtayo. Your healthcare provider will monitor you for these complications
Getting medical treatment right away may help keep these problems from becoming more serious. Your healthcare provider will check you for these problems during your treatment with Libtayo. Your healthcare provider may treat you with corticosteroid or hormone replacement medicines. Your healthcare provider may also need to delay or completely stop treatment with Libtayo if you have severe side effects.
Before you receive Libtayo, tell your healthcare provider about all your medical conditions, including if you:
-- have immune system problems such as Crohn’s disease, ulcerative colitis, or lupus
-- have received an organ transplant
-- have received or plan to receive a stem cell transplant that uses donor stem cells (allogeneic)
-- have received radiation treatment to your chest area
-- have a condition that affects your nervous system, such as myasthenia gravis or Guillain-Barré syndrome
-- are pregnant or plan to become pregnant. Libtayo can harm your unborn baby
Females who are able to become pregnant:
- Your healthcare provider will give you a pregnancy test before you start treatment.
- You should use an effective method of birth control during your treatment and for at least 4 months after your last dose of Libtayo. Talk with your healthcare provider about birth control methods that you can use during this time.
- Tell your healthcare provider right away if you become pregnant or think you may be pregnant during treatment with Libtayo.
-- are breastfeeding or plan to breastfeed. It is not known if Libtayo passes into your breast milk. Do not breastfeed during treatment and for at least 4 months after the last dose of Libtayo.
Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
The most common side effects of Libtayo when used alone include muscle or bone pain, tiredness, rash, and diarrhea. The most common side effects of Libtayo when used in combination with platinum-containing chemotherapy include hair loss, muscle or bone pain, nausea, tiredness, numbness, pain, tingling, or burning in your hands or feet, decreased appetite. These are not all the possible side effects of Libtayo. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

About Regeneron’s VelocImmune Technology
Regeneron’s VelocImmune technology utilizes a proprietary genetically engineered mouse platform endowed with a genetically humanized immune system to produce optimized fully human antibodies. When Regeneron’s co-Founder, President and Chief Scientific Officer George D. Yancopoulos was a graduate student with his mentor Frederick W. Alt in 1985, they were the first to envision making such a genetically humanized mouse, and Regeneron has spent decades inventing and developing VelocImmune and related VelociSuite® technologies. Dr. Yancopoulos and his team have used VelocImmune technology to create approximately one in five of all original, FDA-approved or authorized fully human monoclonal antibodies. This includes REGEN-COV® (casirivimab and imdevimab), Dupixent® (dupilumab), Libtayo, Praluent® (alirocumab), Kevzara® (sarilumab), Evkeeza® (evinacumab-dgnb) and Inmazeb™ (atoltivimab, maftivimab and odesivimab-ebgn).
Regeneron is a leading biotechnology company that invents, develops and commercializes life-transforming medicines for people with serious diseases. Founded and led for nearly 35 years by physician-scientists, our unique ability to repeatedly and consistently translate science into medicine has led to nine FDA-approved treatments and numerous product candidates in development, almost all of which were homegrown in our laboratories. Our medicines and pipeline are designed to help patients with eye diseases, allergic and inflammatory diseases, cancer, cardiovascular and metabolic diseases, pain, hematologic conditions, infectious diseases and rare diseases.
Regeneron is accelerating and improving the traditional drug development process through our proprietary VelociSuite technologies, such as VelocImmune, which uses unique genetically humanized mice to produce optimized fully human antibodies and bispecific antibodies, and through ambitious research initiatives such as the Regeneron Genetics Center®, which is conducting one of the largest genetics sequencing efforts in the world.
