Conditions: Advanced Non-squamous Non-small-cell Lung Cancer; Recurrent Non-Squamous Non-Small Cell Lung Cancer; Metastatic Non-squamous Non Small Cell Lung Cancer

Summary: the goal of this clinical trial is to evaluate the efficacy and safety of albumin-bound paclitaxel-lenvatinib-pembrolizumab in advanced nonsquamous nsclc patients after progression to first-line anti-pd-1/l1 inhibitor with platinum-doublet chemotherapy. all participants will be given with albumin-bound paclitaxel, lenvatinib and pembrolizumab.


Eligibility criteria:
inclusion criteria 1. male/female participants who are at least 18 years of age on the day of signing informed consent (icf) with histologically confirmed diagnosis of metastatic nonsquamous nsclc (ajcc staging manual, version 8) will be enrolled in this study. 2. contraceptive use by men and women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. 3. male participants are eligible to participate the study if they agree to the following during the intervention period and for at least 180 days after the last dose of study intervention: be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis) and agree to remain abstinent or must agree to use contraception unless confirmed to be azoospermia (vasectomized or secondary to medical cause) as: a. agree to use a male condom plus partner use of an additional contraceptive method when having penile-vaginal intercourse with a woman of childbearing potential (wocbp) who is not currently pregnant. note: men with a pregnant or breastfeeding partner must agree to remain abstinent from penile-vaginal intercourse or use a male condom during each episode of penile-vaginal penetration. b. contraceptive use by men should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. if the contraception requirements in the local label for any of the study interventions is more stringent than the requirements above, the local label requirements are to be followed. c. please note that 7 days after lenvatinib is stopped, if the participant is on pembrolizumab only, no male contraception measures are needed d. refrain from donating sperm for at least 120 days after the last dose of lenvatinib. 4. female participant is eligible to participate if she is not pregnant or not breastfeeding, and at least one of the following conditions applies: a. not a woman of childbearing potential (wocbp). b. a wocbp who agrees to follow the contraceptive method that is highly effective (with a failure rate of \<1% per year), with low user dependency, or be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis), during the treatment period and for at least 120 days after the last dose of pembrolizumab or 30 days after the last dose of lenvatinib, study treatment, and agrees not to donate eggs (ova, oocytes) to others or freeze/store these for her own use for the purpose of reproduction during this period. the investigator should evaluate the potential for contraceptive method failure (i.e., noncompliance, recently initiated) in relationship to the first dose of study intervention. c. a wocbp must have negative highly sensitive pregnancy test (urine or serum as required by local regulations) within 24 hours before the first dose of study intervention. d. if a urine test cannot be confirmed as negative (i.e., an ambiguous result), a serum pregnancy test is required. in such cases, the participant must be excluded from participation if the serum pregnancy result is positive. e. the investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy. 5. participants must have progressed on treatment with an anti-pd-1/l1 mab administered in combination with platinum doublet chemotherapy concomitantly as first line treatment. participants who have received anti-pd-1/pd-l1(either as monotherapy or in combination with chemotherapy) as initial treatment at early-stage or locally advanced nsclc should not be enrolled in this study. anti-pd-1/pd-l1 treatment progression is defined by meeting all of the following criteria: a. has received at least 2 doses of an approved anti-pd-1/l1 mab b. has demonstrated disease progression after anti-pd-1/l1 as defined by recist v1.1. the initial evidence of pd is to be confirmed by a second assessment no less than 4 weeks from the date of the first documented disease progression, in the absence of rapid clinical progression. eligible participants should have at least 2 pre-study images as confirmed evidence of pd (assessed by investigator) on treatment of anti-pd-1/l1 mab before the study intervention. c. progressive disease has been documented within 12 weeks from the last dose of anti-pd-1/l1 mab, 6. have confirmation that egfr-, alk-, or ros1-directed therapy is not indicated as primary therapy. subjects who have failed directed therapy are not eligible for the study. 7. the participant (or legally acceptable representative if applicable) provides written informed consent for the trial. 8. have measurable disease (at least 1 measurable lesion by ct or mri) based on recist 1.1. lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions. 9. have an eastern cooperative oncology group (ecog) performance status of 0 to 1. evaluation of ecog is to be performed within 7 days prior to the first dose of study intervention. 10. have a life expectancy of at least 3 months and adequate organ function as defined in the following table. 11. have adequately controlled blood pressure (bp) with or without antihypertensive medications, defined as bp≤150/90mmhg and no change in antihypertensive medications within 1 week before treatment initiation. exclusion criteria: 1. a wocbp who has a positive urine pregnancy test within 72 hours prior to treatment initiation. if the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required. 2. has received prior therapy at any stage of disease with any anti-vegf-tkis (i.e. bevacizumab, lenvatinib, anlotinib, apatinib, etc.) as monotherapy or in combination with an anti-pd-1/l1 inhibitor. 3. has received prior paclitaxel, docetaxel or albumin-paclitaxel as monotherapy or in combination with other therapies at any stage of disease. 4. has received prior radiotherapy within 2 weeks of start of study intervention or has received lung radiation therapy \>30 gy within 6 months before the first dose of study intervention. participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis. a 1-week washout is permitted for palliative radiation (≤2 weeks of radiotherapy) to non-cns disease. 5. has had major surgery within 3 weeks prior to first dose of study interventions. note: adequate wound healing after major surgery must be assessed clinically, independent of time elapsed for eligibility. 6. active hemoptysis (bright red blood of at least 0.5 teaspoon) within 3 weeks prior to the first dose of study drug. 7. has radiographic evidence of major blood vessel invasion/infiltration. in the chest, major blood vessels include the main pulmonary artery, the left and right pulmonary arteries, the 4 major pulmonary veins, the superior or inferior vena cava, and the aorta. note: the degree of proximity to major blood vessels should be considered because of the potential risk of severe hemorrhage associated with tumor shrinkage/necrosis following lenvatinib therapy. 8. has preexisting ≥grade 3 gastrointestinal or non-gastrointestinal fistula. 9. has urine protein ≥1 g/24 hours. note: participants with proteinuria ≥2+ (≥100 mg/dl) on

lenvatinib 12. has received a live vaccine or live-attenuated vaccine within 30 days before the first dose of study intervention. administration of killed vaccines is allowed. 13. is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of study intervention. 14. has clinically significant cardiovascular disease within 12 months from first dose of study intervention, including new york heart association class iii or iv congestive heart failure, unstable angina, myocardial infarction, cerebral vascular accident, or cardiac arrhythmia associated with hemodynamic instability. note: medically controlled arrhythmia would be permitted. 15. has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of study drug. 16. has a known history of an additional malignancy, except if the participant has undergone potentially curative therapy with no evidence of disease recurrence for 3 years since initiation of that therapy. note: the requirement for no evidence of disease for 3 years does not apply to the nsclc for which a participant is enrolled in the study. this time requirement also does not apply to participants who underwent successful definitive resection of basal cell carcinoma of the skin, superficial bladder cancer, squamous cell carcinoma of the skin, in situ cervical cancer, or other in situ cancers. 17. has known active cns metastases and/or carcinomatous meningitis. participants with previously treated brain metastases may participate provided they are radiologically
