observational study of the efficacy and safety of anlotinib combined with penpulimab in elderly lung cancer patients

Conditions: Lung Cancer; Lung Carcinoma; Non Small Cell Lung Cancer; Non-small Cell Carcinoma; Lung Neoplasm

Summary: this prospective observational study will evaluate the efficacy and safety of anlotinib in combination with penpulimab in elderly patients with lung cancer. data will be collected from each patient at baseline and after 4-6 cycles of therapy.

this research study is a phase iv clinical trial. participants are being involved in the portion of the study to observe the efficacy and safety of an observational intervention and also tries to evaluate the disease control rate (such as progression-free-survival, overall survival, objective response rate, disease control rates, duration of response, quality of life and adverse events). anlotinib is a small molecule multi-target tyrosine kinase inhibitor, can effectively inhibit vegfr, pdgfr, fgfr, c-kit and other kinases, with anti-tumor angiogenesis and tumor growth inhibiting effects. penpulimab injection is a new pd-1 monoclonal antibody drug, was approved for marketing by the state drug administration (nmpa) of china for the indication: treatment of adult patients with relapsed or refractory classic hodgkin's lymphoma (r/r chl) who have undergone at least second-line systemic chemotherapy. by putting these two drugs together, the investigators hope that it will have a greater effect on cancer growth in elderly patients with lung cancer. efficacy evaluation was performed every 2 cycles during the follow-up study. patients with disease control (complete response (cr)+partial response (pr)+stable disease (sd)) and tolerable adverse reactions continued to take the drug until the investigator considered that the patient was not suitable to continue the drug or the efficacy was evaluated as disease progression (pd). safety evaluations were performed concurrently with the dosing period. no other antitumor therapy can be administered until pd. the purpose of this study is to: * test the efficacy of these two drugs anlotinib and penpulimab in elderly lung cancer; * determine the progression-free-survival of the combination; * further evaluate the side effect profile for the combination of anlotinib and penpulimab in elderly lung cancer patients.

* prothrombin time (pt) ≤ 1.5 x uln ; * thyrotropic hormone (tsh) ≤ uln (when tsh value is abnormal, t3 and t4 levels is normal, which can be enrolled); * urine protein \< (++), or 24-hour urine protein amount \< 1.0 g ; * patients must have adequate cardiac function, defined as: left ventricular ejection fraction (lvef) \> 50% as determined by cardiac echocardiogram. -patients enrolled in this study voluntarily and signed an informed consent with a good compliance. exclusion criteria: * participants who have active infection; * patients with known immunodeficiency diseases (e.g. psoriasis, active arthritis, immune nephropathy, hiv, etc); * participants with no measurable disease; * patients with cancerous meningitis and spinal cord compression; * participants with active central nervous system (cns) metastases (clinically stable and maintained for at least 2 weeks after adequate treatment of cns metastases and do not require treatment such as glucocorticoids and dehydrating drugs are eligible for enrollment); * previously treated with chemotherapy drugs (except neoadjuvant therapy) / targeted drugs / immunotherapy; * participants who were confirmed severe abnormalities of gastrointestinal function (e.g. inability to take oral medications, uncontrollable nausea or vomiting, history of major gastrointestinal resection, untreated recurrent diarrhea, untreated gastric disease requiring long-term acid-suppressing ppi-like medications, crohn's disease, ulcerative colitis); * patients with central squamous lung cancer on imaging; * patients who had an arterial/venous thrombotic event within 6 months, such as cerebrovascular accident (temporary ischemic attack is excluded), deep vein thrombosis and pulmonary embolism; * patients whose imaging shows that the tumor has invaded a significant vessel or have a high risk of fatal hemorrhage due to tumor invasion of a significant vessel during the follow-up study judged by the investigator; or who have bleeding tendencies (e.g., active peptic ulcer) or receiving thrombolytic or anticoagulant therapy such as warfarin, heparin, or their analogs; * patients who had antineoplastic therapy against other malignancies, including radiotherapy, chemotherapy, immunotherapy and herbal medicine (except previously eradicated malignancies without recurrent metastases for ≥ 5 years); * patients with uncontrollable pleural effusion, pericardial effusion or ascites requiring repeated drainage (except patients who do not require drainage of effusion or whose effusion does not increase significantly after 3 days of cessation of drainage); * patients who have used immunosuppressive drugs within 4 weeks prior to the study treatment, except for topical glucocorticoids by nasal spray, inhalation or other routes or physiologic doses of systemic glucocorticoids (no more than 10 mg/day of prednisone or equivalent doses of other glucocorticoids); * patients who have known or suspected active autoimmune disease (congenital or acquired), such as interstitial pneumonia, uveitis, enterocolitis, hepatitis, pituitary inflammation, vasculitis, nephritis, thyroiditis, etc. (patients with vitiligo or asthma that has completely resolved in childhood and does not require any intervention in adulthood may be enrolled; patients with type i diabetes with good insulin control may be enrolled); * patients who have known allogeneic organ transplantation (except corneal transplantation) or allogeneic hematopoietic stem cell transplantation;
