Non-Small Cell Lung Cancer With EGFR T790M MutationWith Brain and/or Leptomeningeal Metastasis1 more

AZD9291 is an oral potent irreversible EGFR TKI selective for sensitizing EGFR mutation and T790M resistance mutation but sparing wild-type EGFR. Preclinical studies indicate that AZD9291 has significant exposure in the brain and activity against EGFR mutant brain metastasis. In addition, anti-tumor activities of AZD9291 in patients with advanced stage EGFR mutant NSCLC including patients with brain metastasis have been reported in an ongoing Phase I study. More recently, AZD9291 at a dose of 160mg also showed promising efficacy in heavily pre-treated patients with leptomeningeal disease from EGFR mutant NSCLC. Among 11 evaluable for response, 6 patients had LM imaging improvement and 3 out of 7 patients with abnormal neurological exam at baseline had symptomatic improvement. Compared to AZD9291, other 3rd generation EGFR TKIs, rociletinib or HM61713 has not been reported to be effective in most of CNS disease of NSCLC. Further, previous studies with AZD9291 showed anecdotal case series or undetermined for T790M mutation status, indicating more systematic study is warranted. Based on these data, the investigators are going to conduct phase II study of AZD9291 in NSCLC patients harboring T790M mutation who failed EGFR TKIs and brain and/or leptomeningeal metastasis.

Osimertinib With or Without Bevacizumab for EGFR- Mutant Non-small Cell Lung Cancer With Leptomeningeal...

Leptomeningeal MetastasisNon-small Cell Lung Cancer1 more

Leptomeningeal metastasis (LM) is a devastating and terminal complication of advanced non-small-cell lung cancer (NSCLC), especially in patients harboring epidermal growth factor receptor (EGFR) mutations. Osimertinib is an oral,third-generation, irreversible epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) that selectively inhibits both EGFR-TKI-sensitizing and EGFR T790M resistance mutations .AURA I/II study and other preclinical study suggested that Osimertinib exhibited a better blood-brain barrier(BBB) penetration than the other EGFR-TKIs (gefitinib, erlotinib, or afatinib).The BLOOM 、AURA and FLURA study demonstrated that osimertinib showed encouraging activity and manageable tolerability in pretreated EGFR-mutant NSCLC patients with LM. Bevacizumab is a monoclonal antibody against vascular endothelial growth factor (VEGF). Animal study and autopsy specimens showed that VEGF is an essential factor in LM. Recently study showed EGFR-TKIs plus bevacizumab prolonged PFS and OS in patients with EGFR-mutant NSCLC and multiple brain mteastasis when compared with EGFR-TKIs alone. Howerver osimertinib combined with bevacizumab could benefit patients with LM from EGFR- mutant NSCLC remains undetermined. Therefore, the purpose of the study is to evaluate the safety and efficacy of osimertinib combined with bevacizumab for EGFR- mutant non-small cell lung cancer with leptomeningeal metastasis

Clinical and Pharmacological Study With 2B3-101 in Patients With Breast Cancer and Leptomeningeal...

Meningeal Carcinomatosis

Leptomeningeal metastases (LM) develop when tumor cells reach the cerebrospinal fluid (CSF) and infiltrate the leptomeninges. The median survival of patient with breast cancer and LM is 4-6 months with up to 25% long-term survivors. Many potentially highly efficacious intravenous chemotherapies are currently not effective to treat LM because they do not adequately cross the blood-CSF barrier. Doxorubicin, the anthracycline chemotherapeutic agent, has a well-established antineoplastic activity in breast cancer. To optimally enhance the delivery of liposomal doxorubicin to the brain, to-BBB technologies B.V. has designed a glutathione (GSH) pegylated liposomal doxorubicin hydrochloride formulation (2B3-101). Coating of liposomes with PEG ensures the prolonged circulation time in plasma, whilst conjugation of GSH to the tips of the PEG molecules targets the liposomes towards the active GSH transporters on the BBB to enhance the delivery of doxorubicin to the brain. This is a a clinical and pharmacological study that aims to determine preliminary efficacy of treatment with 2B3-101 in patients with leptomeningeal metastases of breast cancer using the LM response score.

Osimertinib With Bevacizumab for Leptomeningeal Metastasis From EGFR-mutation Non-Small Cell Lung...

Leptomeningeal MetastasisNon-small Cell Lung Cancer1 more

Leptomeningeal metastasis (LM) is a fatal complication of advanced non-small cell lung cancer (NSCLC) associated with poor prognosis and rapid deterioration of performance status. The incidence of LM is increasing, reaching 3.8% in molecularly unselected NSCLC patients, being more frequent in adenocarcinoma subtype and up to 9% in epidermal growth factor receptor mutation (EGFRm) lung cancer patients, one-third of patients have concomitant brain metastasis . This increased incidence may in part be conducive to the increased survival of patients with EGFRm advanced NSCLC since the introduction of EGFR-tyrosine kinase inhibitions (TKIs).Currently, no standard therapeutic regimen for LM has been established because of its rarity and heterogeneity[11], and no approved therapies exists to specifically target LM in patients with EGFRm NSCLC. TKIs therapy is the first-line treatment of patients with EGFRm of NSCLC. The leptomeningeal space is a sanctuary site for tumour cells and therapeutic agents due to the presence of an active blood-brain barrier (BBB), so CSF concentration is an important factor affecting treatment of LM by TKIs. Standard-dose first- and second-generation EGFR-TKIs have good systemic efficacy but sub-optimal CNS penetration, as evidenced by preclinical studies of brain distribution and clinical reports of CSF penetration[15, 16]. Osimertinib is a third-generation EGFR-TKI, irreversible, oral EGFR-TKI that potently and selectively inhibits both EGFR-TKI sensitizing and EGFR T790M resistance mutations, which has demonstrated efficacy in NSCLC CNS metastasis[17-22]. Preclinical, I/II clinical studies and AURA program (AURA extension, AURA2, AURA17 and AURA3) have shown that Osimertinib has higher brain permeability than the first- and second-generation. Bevacizumab is a recombinant humanized monoclonal antibody against vascular endothelial growth factor (VEGF), animal studies and autopsy specimens show that VEGF plays an important role in LM. VEGF and EGFR share many overlapping and parallel downstream pathways. The biological rationale shows that inhibiting of EGFR and VEGR signaling pathways could improve the efficacy of antitumor and remove the resistance of EGFR inhibition. Besides, preclinical researches have shown the similar results. Based on these, numbers of clinical trials have confirmed that VEGF inhibitors in combination with EGFR-TKI significantly prolong patients' survival.

Leptomeningeal Metastasis

The purpose of this study is to learn whether the DNA from cancer tumor cells can be found in the cerebral spinal fluid (CSF) that bathes the brain and spinal cord of patients before malignant the cancer cells themselves are able to be found in the CSF. The researchers doing this study hope this information can be used to develop a way to diagnose LM earlier .

Leptomeningeal MetastasisLeptomeningeal Disease3 more

The FORESEE Study is a multi-center, prospective clinical trial enrolling patients with Breast or Non-Small Cell Lung Cancer (NSCLC) who have suspicious or confirmed Leptomeningeal Metastases (LM). Standard of Care methods to diagnose, or assess the treatment response of LM (Clinical Evaluation, MRI and Cytology) have limited sensitivity and specificity. This creates challenges for physicians to manage LM or determine the best course of treatment. CNSide, is a Laboratory Developed Test (LDT ) that is used commercially at the Physician's discretion in Biocept's CLIA certified, CAP accredited laboratory. CNSide can detect and quantify tumor cells in the CSF from patients with Breast Cancer or NSCLC having a suspicious or confirmed LM. The goal of the FORESEE Study is to evaluate the performance of CNSide in monitoring the LM's response to treatment and to assess the impact of CNSide on treatment decisions made by Physicians.
