About this study

The main questions to answer are: * Is the combination of Pemetrexed and Nivolumab safe to inject? * How effective is the combination in disease control? Participants will: * Intrathecal injection of 30 mg pemetrexed via Ommaya reservoir, once every 4 weeks until disease progression; * Intrathecal injection of 40 mg nivolumab via Ommaya reservoir, once every 4 weeks until disease progression; * Before each intrathecal administration, a preliminary intrathecal injection of dexamethasone, 5 mg/2 mL, is given.
