This study will be treated with combination of Pembrolizumab 200mg plus platinum doublet based on histology subtypes.


Condition or disease Intervention/treatment Phase
Non-small Cell Lung Cancer Drug: Pemetrexed, Carboplatin, Pembrolizumab Drug: Paclitaxel, Carboplatin, Pembrolizumab Phase 2

Detailed Description:

This is a Phase II single center, open-label, single arm study in patients with advanced non-small cell lung cancer (stage IV) with brain metastases. Patients will be treated with combination of Pembrolizumab 200mg plus platinum doublet based on histology subtypes. After the 4 cycles of combination phase with cytotoxic chemotherapy, maintenance phase will be followed for maximum of 35 cycles. If the disease progression is observed in CNS only which can be controlled with local treatment, systemic treatment can be continued as beyond disease progression.

Non-squamous cell carcinoma:

4 cycles of pemetrexed 500mg/m2 + carboplatin AUC 5.0 + pembrolizumab 200mg every 3 weeks Followed by pemetrexed 500mg/m2 + pembrolizumab 200mg every 3 weeks up to 35 cycles

Squamous cell carcinoma:

4 cycles of paclitaxel 200mg/m2 + carboplatin AUC 6.0 + pembrolizumab 200mg every 3 weeks Followed by pembrolizumab 200mg every 3 weeks up to 35 cycles

Primary Outcome Measures :
  1. Intracranial response rate [ Time Frame: Up to 30 months ]
    To evaluate the effectiveness of combination regimen in intracranial lesion. The overall response rate will be measured by RECIST v1.1 criteria.


Secondary Outcome Measures :
  1. Progression free survival (PFS) [ Time Frame: The time until the date of either disease progression or the all-cause mortality from the date of IP administration. Up to 30 months ]
    It is a measure of the period of survival without disease progression

  2. Overall survival (OS) [ Time Frame: The time until defined by date of all-cause mortality from the date of IP Administration. Up to 30 months. ]
    Overall survival defined by date of all-cause mortality from the date of IP Administration will be calculated.

  3. Intracranial duration of response [ Time Frame: Up to 30 months. ]
    The duration for intracranial response will be calculated separately to evaluate the intracranial efficacy of IP drug

  4. Intracranial progression-free survival [ Time Frame: Up to 30 months. ]
    Progression free survival of intracranial disease defined by the date of disease progression of intracranial lesion from the date of IP administration will be calculated.

  5. Objective response rate [ Time Frame: Up to 30 months. ]
    Objective response rate of disease will be measured by RECIST v 1.1 criteria.

  6. Adverse events [ Time Frame: from the date of informed consent signature to 30 days after last drug administration ]
    Adverse event will be evaluated using CTCAE v5.0


Other Outcome Measures:
  1. Exploratory analyses based on PD-L1 expression [ Time Frame: Up to 30 months. ]
    The exploratory analyses based on the PD-L1 expression (by DAKO PD-L1 22C3 assay) from the baseline samples will be used for the exploratory analyses in subjects who are available for the PD-L1 test

Ages Eligible for Study:   19 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Male/female participants who are at least 19 years of age on the day of signing informed consent with histologically confirmed diagnosis of stage IV non-small cell lung cancer with brain metastases will be enrolled in this study.
  2. Must have at least one intracranial target lesion. Intracranial lesion must be equal or greater than the 10mm in longest diameter.
  3. Have confirmation that EGFR or ALK-directed therapy is not indicated
  4. Have measurable disease based on RECIST 1.1 as determined by the local site investigator/radiology assessment. Target lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions. Otherwise, previously treated with radiation is not considered as measurable lesion.
  5. Have not received prior systemic treatment for their advanced/metastatic NSCLC. Subjects who received adjuvant or neoadjuvant therapy are eligible if the adjuvant/neoadjuvant therapy was completed at least 6 months prior to the development of metastatic disease.
  6. Have a life expectancy of at least 3 months
  7. Have a performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) Performance Status.
  8. Have adequate organ function
  9. Male participants: A male participant must agree to use a contraception during the treatment period and for at least 120 days after the last dose of study treatment and refrain from donating sperm during this period.
  10. A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies:

    • a. Not a woman of childbearing potential (WOCBP) as defined in Appendix 3 OR

  11. The participant (or legally acceptable representative if applicable) provides written informed consent for the trial.

Exclusion Criteria:

  1. A WOCBP who has a positive urine pregnancy test within 72 hours prior to IP administration. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
  2. Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti PD L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (eg, CTLA-4, OX 40, CD137).
  3. Has received prior systemic anti-cancer therapy including investigational agents prior to IP administration as a metastatic disease treatment, including tyrosine kinase inhibitor.

  5. No measurable CNS lesion other than CNS lesion treated with stereotactic radiotherapy or surgery
  6. Had received whole brain radiotherapy or stereotactic radiotherapy to CNS disease.
  7. Has received prior radiotherapy within 1 weeks of start 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 to non-CNS disease.
  8. Has received a live vaccine within 30 days prior to the first dose of study drug. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin (BCG), and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (eg, FluMist®) are live attenuated vaccines and are not allowed.

  13. Has severe hypersensitivity (≥Grade 3) to pembrolizumab and/or any of its excipients.
  14. Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment and is allowed.
  15. Has a history of (non-infectious) pneumonitis that currently required steroids or has current pneumonitis.

These patients can be participated with appropriate treatment and prophylactic treatment based on the investigator's decision.
  19. Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the participant's participation for the full duration of the study, or is not in the best interest of the participant to participate, in the opinion of the treating investigator.
  20. Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
