  "Description": "Two-stage design for single-arm phase II trials with\ntime-to-event endpoints (e.g., clinical trials on\nimmunotherapies among cancer patients) can be calculated using\nthis package. Two notable advantages of the package: 1) It\nprovides flexible choices from three design methods (optimal,\nminmax, and admissible), and 2) the power of the design is more\naccurately calculated using the exact variance in the\none-sample log-rank test. The package can be used for 1)\nplanning the sample sizes and other design parameters, and 2)\nconducting the interim and final analyses for the Go/No-go\ndecisions. More details about the design method can be found\nin: Wu, J, Chen L, Wei J, Weiss H, Chauhan A. (2020).\n<doi:10.1002/pst.1983>.",
