Frequently asked questions about Cemiplimab-Rwlc

What is Cemiplimab-Rwlc used for in Non-small Cell Lung Cancer Stage III?

Cemiplimab-Rwlc is being studied for the treatment of Non-small Cell Lung Cancer Stage III, specifically in a neoadjuvant setting. It is administered as part of a chemo-immunotherapy regimen before surgical resection in patients with locally advanced disease and N3 lymph node involvement. The drug is currently in Phase 2 clinical development.

What does Cemiplimab-Rwlc target?

Cemiplimab-Rwlc targets the PD-1 receptor, a protein on immune cells that tumors can exploit to evade detection. By blocking PD-1, the drug helps the immune system recognize and attack cancer cells. This mechanism is being evaluated in the context of non-small cell lung cancer, where it is combined with chemotherapy before surgery.

Who makes Cemiplimab-Rwlc?

Cemiplimab-Rwlc is developed by Regeneron Pharmaceuticals, Inc., a biopharmaceutical company traded on the Nasdaq under the ticker symbol REGN. The company is conducting a Phase 2 clinical trial to evaluate the drug in patients with stage III non-small cell lung cancer.

What phase is Cemiplimab-Rwlc in?

Cemiplimab-Rwlc is in Phase 2 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities. The ongoing trial is recruiting patients with Non-small Cell Lung Cancer Stage III to assess the safety and efficacy of the neoadjuvant chemo-immunotherapy approach.

What clinical trials is Cemiplimab-Rwlc in?

Cemiplimab-Rwlc is being evaluated in a single Phase 2 clinical trial with the identifier NCT06449313. This trial, titled 'Neoadjuvant Chemo-Immunotherapy and Surgical Resection in Locally Advanced Non-small Cell Lung Cancer With N3 Lymph Node Involvement,' is recruiting 21 participants in the United States. The study is uncontrolled and not blinded.

Is Cemiplimab-Rwlc the same as Libtayo?

Cemiplimab-Rwlc is the generic name for the drug marketed as Libtayo. However, in the context of this specific clinical trial, the drug is being tested as a neoadjuvant treatment for stage III non-small cell lung cancer. The trial is sponsored by Regeneron Pharmaceuticals and is currently in Phase 2 development.
