TARRYTOWN, N.Y., May 13, 2020 /PRNewswire/ --
Regeneron will host investor webcast on Monday, June 1 to discuss oncology program strategy and progress
Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced the company will share updates from its diverse clinical oncology portfolio at the 2020 American Society of Clinical Oncology (ASCO) Annual Meeting from May 29-31 taking place virtually.
Among the accepted abstracts are new, longer-term data for PD-1 inhibitor Libtayo® (cemiplimab-rwlc) in advanced cutaneous squamous cell carcinoma (CSCC). The data published today, which will be updated during ASCO, add to the most mature dataset for any therapy in advanced CSCC and show that median overall survival and median duration of response have yet to be reached for Libtayo-treated patients with no new safety signals observed. Additional abstracts outline the clinical trial designs for Regeneron's first costimulatory bispecific REGN5678 (PSMAxCD28) in metastatic castration-resistant prostate cancer and the company's first tumor-targeted bispecific REGN5093 (METxMET) in MET-altered advanced non-small cell lung cancer (NSCLC).
"Regeneron is committed to advancing an oncology program to potentially transform treatment paradigms across multiple solid tumors and blood cancers where there are significant unmet needs," said Israel Lowy, M.D., Senior Vice President, Translational and Clinical Sciences, Oncology at Regeneron. "We've already made significant progress. Libtayo is the standard of care for advanced cutaneous squamous cell carcinoma, and we recently announced clinically meaningful outcomes from our pivotal Libtayo trials in advanced non-small cell lung cancer and advanced basal cell carcinoma. At ASCO, we will build on these milestones with three-year data from Libtayo in advanced cutaneous squamous cell carcinoma and updates from our expanding bispecific antibody platform."

About the Regeneron Bispecific Antibody Platform
All of Regeneron's bispecifics are designed to closely resemble natural human antibodies and bind to two different targets. They are derived from a next-generation version of Regeneron's proprietary VelocImmune® technology and created using the company's Veloci-Bi® platform. These allow for the creation of bispecifics with no linkers or artificial sequences. Additionally, Regeneron bispecifics are manufactured using similar approaches used for human antibody medicines, with similar pharmacokinetics.
There are six Regeneron investigational bispecific antibodies currently in ongoing clinical trials for multiple blood cancers and solid tumors. These bispecifics fall into three categories:
- CD3 bispecifics are designed to bridge T-cells and tumor cells. At the tumor site, they activate T-cells via their CD3 receptors and promote T-cell killing of the cancer cells. Investigational candidates include:
- CD20xCD3 (odronextamab) for B-cell non-Hodgkin lymphoma;
- Two distinct BCMAxCD3s (REGN5458 and REGN5459) for multiple myeloma;
- MUC16xCD3 (REGN4018) for ovarian cancer.
- CD28 costimulatory bispecifics are also designed to bridge T-cells and tumor cells. At the tumor site, they costimulate T-cells via their CD28 receptors and may synergize with PD-1 inhibitors and/or CD3 bispecifics. Investigational candidates include:
- PSMAxCD28 (REGN5678) in combination with Libtayo for prostate cancer.
- Tumor-targeted bispecifics are designed to target proteins only on the cancer cell. In this way, they may affect various signaling pathways to hamper the cancer cells' ability to survive and proliferate. Investigational candidates include:
- METxMET (REGN5093) for NSCLC that is driven by MET mutations and/or amplifications. REGN5093 targets two different parts of the MET receptor on cancer cells to degrade the receptor and block its ability to trigger cell proliferation.
The bispecifics mentioned in this release are currently under clinical development, and their safety and efficacy have not been evaluated by any regulatory authority. Libtayo in combination with REGN5678 is currently under clinical development for metastatic castration-resistant prostate cancer, and its safety and efficacy have not been evaluated by any regulatory authority for this use.
As part of a global collaboration agreement, Regeneron and Sanofi are jointly developing the BCMAxCD3 and MUC16xCD3 bispecific programs.
Libtayo is a fully-human monoclonal antibody targeting the immune checkpoint receptor PD-1 on T-cells. By binding to PD-1, Libtayo has been shown to block cancer cells from using the PD-1 pathway to suppress T-cell activation.
Libtayo is the first and only immunotherapy approved in the U.S., European Union, and other countries for adults 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 in its approved indication 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.
The extensive clinical program for Libtayo is focused on difficult-to-treat cancers. In skin cancer, this includes a potentially registrational Phase 2 trial in basal cell carcinoma and additional trials in adjuvant and neoadjuvant CSCC. Libtayo is also being investigated in potentially registrational Phase 3 trials in NSCLC and cervical cancer, as well as in trials combining Libtayo with novel therapeutic approaches for both solid tumors and blood cancers. These potential uses are investigational, and their safety and efficacy have not been evaluated by any regulatory authority.
Libtayo was invented using Regeneron's proprietary VelocImmune technology that utilizes a proprietary genetically-engineered mouse platform endowed with a genetically-humanized immune system to produce optimized fully-human antibodies. VelocImmune technology has been used to create multiple antibodies including Dupixent® (dupilumab), Praluent® (alirocumab) and Kevzara® (sarilumab), which are approved in multiple countries around the world. Regeneron previously used these technologies to rapidly develop a treatment for Ebola virus infection, which is currently under review by the FDA, and is now being used in efforts to create preventative and therapeutic medicines for COVID-19.
IMPORTANT SAFETY INFORMATION AND INDICATION FOR U.S. PATIENTS
What is Libtayo?
Libtayo is a prescription medicine used to treat people with a type of skin cancer called cutaneous squamous cell carcinoma (CSCC) that has spread or cannot be cured by surgery or radiation.
It is not known if Libtayo is safe and effective in children.
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.
