简要总结
This study aims to compare the efficacy of afatinib maintenance with pemetrexed maintenance following induction therapy with platinum/ pemetrexed in patients with metastatic epidermal growth factor receptor (EGFR) mutated non-small-cell lung cancer (NSCLC) progressing after first-line treatment with afatinib with respect to progression-free survival.
详细描述
This is a randomized, open-label, phase II study of maintaining pan-ERBB blockade following platinum-based induction chemotherapy in patients with EGFR mutated, metastatic NSCLC progressing after first-line treatment with afatinib.
Patients who have progressed after first-line treatment with afatinib will be screened while receiving an induction phase which consists of at least three but not more than four cycles of cisplatin/carboplatin plus pemetrexed given in 21-day cycles. Patients who do not progress (i.e. complete or partial response, or stable disease - CR, PR or SD) after completion of three or four cycles induction chemotherapy will then be randomized (1:1 ratio) to receive maintenance therapy with either afatinib (40 mg/d, or last dose if reduced during first-line treatment) or pemetrexed (500 mg/m² every 21 days, or 375 mg/m² if dose was reduced during induction therapy) until disease progression, unacceptable toxicity or patient consent withdrawal.

入选标准
- •Histologically or cytologically confirmed diagnosis of non-small-cell lung cancer (NSCLC) with no curative therapeutic option. Patients with Stage IV (UICC 7th edition) disease or Stage IIIB disease not amenable to curative intent surgery or radiotherapy are enrolled. Patients with mixed histology are eligible if NSCLC is the predominant histology
- •Documented somatic EGFR mutation as determined by medically accepted assay technology
- •Patients with documented progression after response (CR/PR) or stable disease (SD) for at least 6 months of treatment with afatinib as first tyrosine kinase inhibitor (either given as first-line therapy or being switched to afatinib after up to 4 courses of platinum-based chemotherapy)
- •Patients who have completed 3 or 4 cycles of cisplatin or carboplatin plus pemetrexed induction chemotherapy prior to randomization leading to documented response (CR/PR) or SD according to RECIST 1.1
- •At least one measurable lesion according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1
- •Male or female patient with age ≥18 years
- •ECOG performance status ≤ 2
- •Adequate organ and bone marrow function, defined as all of the following:
- •Before the last cycle of induction chemotherapy or after hematopoietic recovery from the last cycle of induction chemotherapy:
- •Absolute neutrophil count (ANC) ≥ 1,500 / mm3
- •Platelet count ≥ 100,000 / mm3
- •Creatinine clearance ≥ 45 ml / min (calculated according to Cockroft and Gault, or Tc99m-DPTA clearance or similar methodology). Patients with creatinine clearance of 45 to 79 ml/min should refrain from using NSAID at least 2 days before and 2 days after infusion of pemetrexed. Long-acting NSAID should be terminated 5 days before pemetrexed infusion.
- •Total serum bilirubin ≤ 1.5 times upper limit of institutional normal (ULN)
- •Serum aspartate amino transferase (AST) and serum alanine amino transferase (ALT) ≤ 3 times the upper limit of institutional normal (ULN) ( ≤ 5 times ULN if liver function abnormalities are due to underlying malignancy)
- •Recovered from any previous therapy related toxicity to ≤ Grade 1 at study entry (except for stable sensory neuropathy ≤ Grade 2 and alopecia)
- •Written informed consent
- •Ability to comply with the protocol for the duration of the study, including hospital/office visits for treatment and scheduled follow-up visits and examinations
排除标准
- •Systemic therapy for metastatic disease or relapse other than (a) first-line therapy with afatinib or (b) afatinib given as first EGFR-targeting agent following up to 4 courses of platinum-based chemotherapy with no disease progression between first-line chemotherapy and initiation of afatinib (prior adjuvant chemotherapy is allowed) and 3 to 4 cycles of induction chemotherapy with cisplatin or carboplatin and pemetrexed following afatinib failure
- •Prior treatment with erlotinib, gefitinib or other investigational or approved EGFR-targeting small molecules or antibodies
- •Known EGFR T790M mutation (analysis not mandatory)
- •Major surgery within 4 weeks before starting study treatment or scheduled for surgery during the projected course of the study
- •Extended radiotherapy within 4 weeks prior to randomization, except as follows:
- •Palliative, limited local radiation to non-target lesions (e.g. isolated bone metastases) may be allowed up to 2 weeks prior to randomization, and
- •single dose palliative treatment for symptomatic metastasis outside above allowance to be discussed with sponsor prior to enrolling
- •Active brain metastases except for the followings:
- •Asymptomatic brain metastases incidentally found during screening process which do not require local treatment in the opinion of the investigator.
- •Asymptomatic brain metastases for which local treatment has been given: stable for at least 4 weeks of lower dose corticosteroids (e.g., dexamethasone up to 4 mg/d) and/or non-enzyme-inducing anti-convulsants treatment before study randomization.
- •Brain metastases controlled after surgery and/or radiotherapy
- •Meningeal carcinomatosis
- •Previous or concomitant malignancies at other sites, except effectively treated non-melanoma skin cancers, carcinoma in situ of the cervix, non-invasive bladder cancer, ductal carcinoma in situ of the breast, or effectively treated malignancy that has been in remission for more than 3 years and is considered to be cured. Definitively treated localized low/intermediate risk prostate cancer (Gleason score ≤ 7) is allowed when a rise in serum PSA level by ≥ 2 ng/mL above the nadir is excluded
- •Known pre-existing interstitial lung disease
- •Any history or presence of poorly controlled gastrointestinal disorders that could affect the absorption of the study drug in the opinion of the investigator (e.g. Crohn's Disease, ulcerative colitis, chronic diarrhea, and malabsorption)
- •Clinically relevant cardiovascular abnormalities as judged by the investigator such as uncontrolled hypertension, congestive heart failure ≥ NYHA grade III, unstable angina or myocardial infarction within the past 6 months, or poorly controlled cardiac arrhythmia in the opinion of investigator
- •Any history of or concomitant condition that, in the opinion of the investigator, would compromise the patient's ability to comply with the study or interfere with the evaluation of the efficacy and safety of the test drug, or renders the patient at high risk of treatment complications
- •Women of child-bearing potential and men who are able to father a child, unwilling to be abstinent or use adequate contraception prior to study entry, for the duration of study participation and for at least 2 weeks after treatment has ended
- •Female patient pregnant or breast-feeding
- •Known active infection with HBV, HCV or HIV
- •Any contraindications for therapy with pemetrexed
- •Known hypersensitivity to afatinib or the excipients of any of the trial drugs
- •Concurrent treatment with other experimental drugs or participation in another clinical trial with any investigational drug within 60 days prior to treatment start
- •Pleurocentesis or paracentesis should be considered in patients with clinically significant pleural effusions or ascites if clinically indicated. However, per SmPC of pemetrexed the presence of effusion is not an exclusion criteria
