TARRYTOWN, N.Y. and PARIS,/PRNewswire/ --
Companies select two clinical-stage bispecific antibodies for ongoing collaboration
Regeneron retains full rights to all its other investigational immuno-oncology programs; Sanofi able to independently pursue own immuno-oncology programs
Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) and Sanofi have restructured their global Immuno-oncology Discovery and Development Agreement for new immuno-oncology cancer treatments. The 2015 Agreement was scheduled to end in approximately mid-2020, and this revision provides for ongoing collaborative development of two clinical-stage bispecific antibody programs. The revised agreement allows Regeneron to retain all rights to its other immuno-oncology discovery and development programs and provides Sanofi increased flexibility to advance its early-stage immuno-oncology pipeline independently.
Under the terms of the restructured Agreement:
- Sanofi will pay Regeneron $462 million representing the balance of payments due under the original Immuno-oncology Agreement, which covers the Sanofi share of the immuno-oncology discovery program costs for the last quarter of 2018 and up to $120 million in development costs for the two selected clinical-stage bispecific antibodies, plus the termination fee for the other programs under the original immuno-oncology agreement.
- Sanofi secures the right to opt-in to the BCMAxCD3 and MUC16xCD3 bispecific programs when proof of concept is achieved or when the allocated funding is expended.
- Regeneron will commit up to $70 million to further develop the BCMAxCD3 bispecific antibody for multiple myeloma and up to $50 million to further develop the MUC16xCD3 bispecific for mucin-16 expressing cancers.
- Post opt-in, Sanofi will lead development and commercialization of the BCMAxCD3 bispecific and fund 100 percent of development costs, with Regeneron reimbursing up to 50 percent out of its share of collaboration profits. Sanofi and Regeneron will share global profits equally.
- Post opt-in, Regeneron will lead MUC16xCD3 bispecific development and lead commercialization in the U.S. The companies will share development costs and global profits equally. Sanofi will lead commercialization outside the U.S.
- The companies' ongoing collaboration for the development and commercialization of Libtayo® (cemiplimab-rwlc), a PD-1 antibody, is unaffected by the amended Discovery and Development Agreement.
- Regeneron retains full rights to its other immuno-oncology programs.
Under the Immuno-Oncology License and Collaboration Agreement, the companies have developed and received U.S. Food and Drug Administration approval of Libtayo for advanced cutaneous squamous cell carcinoma (CSCC). A regulatory application for Libtayo has also been submitted in the EU. An ongoing joint clinical program is investigating Libtayo in multiple other cancers, and includes potentially pivotal trials in lung, cervical and skin cancers. Libtayo's safety and efficacy has not been fully evaluated by any regulatory authority for indications beyond advanced CSCC.
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.

- 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.

- 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.
