TARRYTOWN, N.Y. and PARIS, July 1, 2019 /PRNewswire/ --
Libtayo is the only treatment approved in the EU for adult patients with metastatic or locally advanced cutaneous squamous cell carcinoma who are not candidates for curative surgery or curative radiation
CSCC is one of the most common skin cancers worldwide and is especially difficult to treat in advanced stages
Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) and Sanofi today announced that the European Commission (EC) has granted conditional marketing authorization for Libtayo® (cemiplimab) for the treatment of adults with metastatic or locally advanced cutaneous squamous cell carcinoma (CSCC) who are not candidates for curative surgery or curative radiation. Libtayo is a fully-human monoclonal antibody targeting the immune checkpoint receptor PD-1 (programmed cell death protein-1) and is the only treatment approved in advanced CSCC in the European Union (EU).
"With no other medical treatments approved for advanced CSCC in the EU, Libtayo represents an important new option for patients affected with this advanced skin cancer who cannot be cured by surgery or radiation," said Axel Hauschild, M.D., Ph.D., an investigator in the pivotal CSCC clinical program and Professor and Head of the Interdisciplinary Skin Cancer Center at the University Hospital Schleswig-Holstein in Kiel, Germany. "Results from the Libtayo pivotal trial are very encouraging and demonstrated substantial and durable responses following Libtayo treatment, including in the elderly and regardless of PD-L1 expression levels."
Updated data from the registrational EMPOWER-CSCC-1 trial were recently shared at the 2019 American Society of Clinical Oncology Annual Meeting.
CSCC is one of the most commonly diagnosed skin cancers worldwide, and its incidence is estimated to be substantially increasing in some European countries. Although the vast majority of patients with CSCC have a good prognosis when discovered early, the cancer can be especially difficult to treat when it progresses to advanced stages. Advanced CSCC includes both patients with locally advanced disease (where the cancer cannot be cured by surgery and/or radiation) and patients with metastatic disease (when the cancer spreads to other parts of the body). Based upon historical data, patients with advanced CSCC have a life expectancy of approximately one year.
The EC approval is based on data from the pivotal, open-label, multi-center, non-randomized Phase 2 trial known as EMPOWER-CSCC-1 (Study 1540) and supported by two advanced CSCC expansion cohorts from a multi-center, open-label, non-randomized Phase 1 trial (Study 1423). These trials provide the largest prospective clinical data set evaluating a systemic therapy in patients with advanced CSCC to date.
The recommended dose of Libtayo is 350 mg every 3 weeks administered by intravenous infusion over 30 minutes. Treatment may be continued until disease progression or unacceptable toxicity.
The conditional approval recognizes the extreme unmet need in advanced CSCC. As part of the conditional approval, Regeneron and Sanofi will add a new patient group to EMPOWER-CSCC-1 to further support the benefit-risk profile of Libtayo, and report the results to the European Medicines Agency (EMA). As is standard practice for conditional approvals, the EMA reviews new information at least every year and updates product labeling as necessary.
Libtayo is being jointly developed by Regeneron and Sanofi under a global collaboration agreement. Libtayo was invented by Regeneron using the company's proprietary VelocImmune® technology that yields optimized fully-human antibodies.
In addition to the EU, Libtayo is also approved in the U.S., Canada and Brazil for adult patients with metastatic CSCC or locally advanced CSCC who are not candidates for curative surgery or curative radiation. In the U.S., the generic name for Libtayo is cemiplimab-rwlc, with rwlc as the suffix designated in accordance with Nonproprietary Naming of Biological Products Guidance for Industry issued by the U.S. Food and Drug Administration.
Beyond the ongoing EMPOWER-CSCC-1 trial, Libtayo is also being investigated in adjuvant and neoadjuvant trials in CSCC and in potential registrational trials in non-small cell lung cancer, basal cell carcinoma and cervical cancer. Additional studies include trials in squamous cell carcinoma of the head and neck, melanoma, colorectal cancer, prostate cancer, multiple myeloma, Hodgkin's lymphoma and non-Hodgkin's lymphoma. These trials are designed to investigate Libtayo as monotherapy; in combination with conventional treatments like chemotherapy; or in combination with other investigational agents, including vaccines, oncolytic viruses and bispecific antibodies, among others. These potential uses are investigational, and their safety and efficacy have not been evaluated by any regulatory authority.
IMPORTANT SAFETY INFORMATION AND INDICATION FOR U.S. PATIENTS
What is the most important information I should know about Libtayo?
Libtayo is a medicine that may treat a type of skin cancer 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. 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 symptoms of the following problems or these symptoms get worse:
- Lung problems (pneumonitis). Signs and symptoms of pneumonitis may include new or worsening cough, shortness of breath, and chest pain.
- Intestinal problems (colitis) that can lead to tears or holes in your intestine. Signs and symptoms of colitis may include diarrhea (loose stools) or more frequent bowel movements than usual; stools that are black, tarry, sticky or that have blood or mucus; and severe stomach-area (abdomen) pain or tenderness.
- Liver problems (hepatitis). Signs and symptoms of hepatitis may include yellowing of your skin or the whites of your eyes, severe nausea or vomiting, pain on the right side of your stomach area (abdomen), drowsiness, dark urine (tea colored), bleeding or bruising more easily than normal, and feeling less hungry than usual.
- Hormone gland problems (especially the adrenal glands, pituitary, thyroid and pancreas). Signs and symptoms that your hormone glands are not working properly may include headaches that will not go away or unusual headaches, rapid heartbeat, increased sweating, extreme tiredness, weight gain or weight loss, dizziness or fainting, feeling more hungry or thirsty than usual, hair loss, feeling cold, constipation, deeper voice, very low blood pressure, urinating more often than usual, nausea or vomiting, stomach-area (abdomen) pain, and changes in mood or behavior, such as decreased sex drive, irritability, or forgetfulness.
- Kidney problems, including nephritis and kidney failure. Signs of these problems may include decrease in your amount of urine, blood in your urine, swelling in your ankles, and loss of appetite.
- Skin problems. Signs of these problems may include rash, itching, skin blistering, and painful sores or ulcers in the mouth, nose, throat, or genital area.
- Problems in other organs. Signs of these problems may include headache, tiredness or weakness, sleepiness, changes in heartbeat (such as beating fast, seeming to skip a beat, or a pounding sensation), confusion, fever, muscle weakness, balance problems, nausea, vomiting, stiff neck, memory problems, seizures (encephalitis), swollen lymph nodes, rash or tender lumps on skin, cough, shortness of breath, vision changes, or eye pain (sarcoidosis), seeing or hearing things that are not there (hallucinations), severe muscle weakness, low red blood cells (anemia), bruises on the skin or bleeding, and changes in eyesight.
- Rejection of a transplanted organ. Your doctor should tell you what signs and symptoms you should report and monitor you, depending on the type of organ transplant that you have had.
- Infusion (IV) reactions that can sometimes be severe and life-threatening. Signs of these problems may include chills or shaking, itching or rash, flushing, shortness of breath or wheezing, dizziness, fever, feeling of passing out, back or neck pain, and facial swelling.
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 delay or completely stop treatment 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 had an organ transplant;
- have lung or breathing problems;
- have liver or kidney problems;
- have diabetes;
- are pregnant or plan to become pregnant; Libtayo can harm your unborn baby.
Females who are able to become pregnant:
- 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 include tiredness, rash, and diarrhea. These are not all the possible side effects of Libtayo. Call your doctor for medical advice about side effects.
