Brief Summary:

The purpose of this research is to examine if an experimental drug combination impacts the survival rate of individuals with Leptomeningeal Metastases

This research study involves an experimental drug combination.

The names of the study drugs involved in this study are:

  • Pembrolizumab
  • Lenvatinib

Condition or disease Intervention/treatment Phase
Solid Tumor Solid Tumor, Adult Leptomeningeal Metastasis Drug: Pembrolizumab Drug: Lenvatinib Phase 2

Detailed Description:

This is a single arm Phase 2 study of pembrolizumab in combination with lenvatinib in patients with leptomeningeal metastases from any solid tumor.

The research study procedures include screening for eligibility and study treatment, including evaluations and follow up visits.

  • The names of the study drugs involved in this study are:
  • Pembrolizumab
  • Lenvatinib

The study treatment will last for up to 35 cycles (a cycle is 21 days long), or until the disease gets worse or unacceptable side effects. Participants will be followed for up to 90 days after the end of the study treatment.

It is expected that about 19 people will take part in this research study.

This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug combination to learn whether the drug combination works in treating a specific disease. "Investigational" means that the drug combination is being studied.

The U.S. Food and Drug Administration (FDA) has not approved pembrolizumab or lenvatinib for this specific disease but each has been approved for other uses.

Primary Outcome Measures :
  1. Proportion of Participants alive at 6 months [ Time Frame: 6 months ]
    The proportion of patients alive at 6 months will be summarized with a 90% confidence interval estimated using the method of Atkinson and Brown (Biometrics, 1985), which allows for the two-stage design. Based on a sample of 19 patients, the confidence interval will be no wider than 33%


Secondary Outcome Measures :
  1. Proportion of Participants with Grade 3 or higher toxicities [ Time Frame: first dose of study treatment up to the 30-Day Post Drug Visit up to 30 Months ]
    The proportion of patients with Grade 3 or higher toxicities will be presented with 90% exact binomial confidence intervals. The incidence of events that are new or worsening from the time of first dose of treatment will be summarized according to system organ class and/or preferred term, severity (based on Common Terminology Criteria for Adverse Events v5.0 CTCAE grade), type of adverse event, and relation to study treatment. Deaths reportable as SAEs and non-fatal serious adverse events will be listed by patient and tabulated by primary system organ class, and type of adverse event

  2. Proportion of evaluable participants with intracranial/intraspinal response [ Time Frame: 30 Months ]
    The proportion of evaluable patients with intracranial/intraspinal response (CR or PR by RANO) will be presented with a two-sided, 90% exact binomial confidence interval.

  3. Proportion of evaluable participants with extracranial response [ Time Frame: 30 Months ]

    The proportion of evaluable patients with extracranial response (CR or PR by RECIST 1.1) will be presented with a two-sided, 90% exact binomial confidence interval.

    For a sample of 19 patients, the confidence interval will have maximum width of 33%


  4. Intracranial/intraspinal Progression Free Survival (IPFS) [ Time Frame: 30 Months ]

    The distribution of intracranial/intraspinal PFS (IPFS) in participants will be summarized using the method of Kaplan-Meier. IPFS is defined as the time from registration to documented intracranial/intraspinal progression (RANO) or death, whichever occurs first.

    Patients who have neither died nor progressed at the time of analysis will be censored at the date of last adequate disease assessment.


  5. Median Intracranial/intraspinal Progression Free Survival (IPFS) [ Time Frame: 30 Months ]

    Median IPFS will be presented and accompanied by 90% confidence intervals estimated using log(-log(survival)) methodology. Point estimates at 3 and 6 months will also be presented with confidence intervals.

    .


  6. Extracranial Progression Free Survival (EPFS) [ Time Frame: 30 Months ]
    The distribution of extracranial PFS (EPFS) will be summarized using the method of Kaplan-Meier. EPFS is defined as the time from registration to documented extracranial progression (RANO) or death, whichever occurs first. Patients who have neither died nor progressed at the time of analysis will be censored at the date of last adequate disease assessment.

  7. Median Extracranial Progression Free Survival (EPFS) [ Time Frame: 30 Months ]
    Median EPFS will be presented and accompanied by 90% confidence intervals estimated using log(-log(survival)) methodology. Point estimates at 3 and 6 months will also be presented with confidence intervals.

  8. Overall Survival [ Time Frame: 30 Months ]
    The distribution of overall survival will be summarized using the method of Kaplan-Meier. (OS) is defined as the time from registration to death due to any cause, or censored at date last known alive

  9. Median Overall Survival [ Time Frame: 30 Months ]
    median OS will be presented and accompanied by 90% confidence intervals estimated using log(-log(survival)) methodology. (OS) is defined as the time from registration to death due to any cause, or censored at date last known alive

  10. Proportion of participants with leptomeningeal metastases from breast cancer alive [ Time Frame: 6 months ]
    The proportion of patients with leptomeningeal metastases from breast cancer alive at 6 months will be summarized with a 90% two-sided, exact binomial confidence interval. The maximum width of the confidence intervals is 0.55.

  • Has a known history of active TB (Bacillus Tuberculosis).
  • Has clinically significant hemoptysis or tumor bleeding within 2 weeks prior to the first dose of study treatment.
  • Bleeding or thrombotic disorders or participants at risk for severe hemorrhage. The degree of tumor invasion/infiltration of major blood vessels (e.g., carotid artery) should be considered because of the potential risk of severe hemorrhage associated with tumor shrinkage/necrosis following lenvatinib therapy.
  • Participants having > 1+ proteinuria on urine dipstick testing unless a 24-hour urine collection for quantitative assessment indicates that the urine protein is <1 g/24 hours.

  • Will need immediate local surgery or radiation for brain metastases.
  • Unable to undergo MRI.
  • Electrolyte abnormalities that have not been corrected.
  • Significant cardiovascular impairment: history of congestive heart failure greater than New York Heart Association (NYHA) Class II, unstable angina, myocardial infarction or stroke within 6 months of the first dose of study drug, or cardiac arrhythmia requiring medical treatment at Screening.
