Privacy The advantage of Penpulimab Injection lies in adopting the IgG1 subtype and undergoing Fc fragment engineering modification, which can effectively reduce antibody-dependent cell-mediated cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC), while enhancing anti-tumor efficacy, optimizing treatment safety and reducing autoimmune-related side effects.
1、Penpulimab is indicated for the treatment of adult patients with relapsed or refractory classical Hodgkin's lymphoma who have received at least two lines of systemic chemotherapy.
This indication is conditionally approved based on the objective response rate and duration of response from a single-arm clinical trial. The full approval of this indication is contingent upon the confirmatory randomized controlled clinical trial (planned) demonstrating a significant clinical benefit of Penpulimab treatment over standard therapy.
2、Penpulimab in combination with paclitaxel and carboplatin is indicated for the first-line treatment of adult patients with locally advanced or metastatic squamous non-small cell lung cancer (NSCLC).
This product must be administered under the guidance of a physician experienced in cancer treatment.
Classical Hodgkin's Lymphoma: This product is administered by intravenous infusion at a recommended dose of 200 mg once every 2 weeks until disease progression or unacceptable toxicity occurs.
Locally Advanced or Metastatic Squamous Non-Small Cell Lung Cancer (NSCLC): This product is administered by intravenous infusion at a recommended dose of 200 mg once every 3 weeks until disease progression or unacceptable toxicity occurs.
When penpulimab is administered in combination with chemotherapy, penpulimab intravenous infusion should be given first, followed by chemotherapy after an interval of at least 30 minutes. See also the prescribing information for the chemotherapeutic agents administered.
Atypical responses may be observed (e.g., temporary tumor enlargement or the appearance of new lesions within the first few months of treatment, followed by tumor regression). If the patient's clinical symptoms are stable or continuously relieved, even if there is initial evidence of disease progression, continuation of treatment with this product may be considered based on the judgment of overall clinical benefit until disease progression is confirmed.
Contraindicated in patients with hypersensitivity to penpulimab or any of the excipients.
