Primary Outcome Measures
NameTimeMethod
Safety of combination camrelizumab and palbociclib as assessed by number of participants who experience adverse eventsup to 15 weeks

Number of participants who experience grade 1 or higher adverse events, as defined by Common Terminology Criteria for Adverse Events version 5.0 (CTCAE v5.0)

Feasibility of combination camrelizumab and palbociclib as assessed by number of participants who experience adverse eventsup to 15 weeks

Patients proceed to surgery without experiencing prolonged treatment-related delays. An extended treatment-related delay will be considered if it exceeds 37 days from the initially scheduled surgery date. In terms of feasibility, if there is any treatment toxicity of any grade that could adversely impact prognosis, as judged by the investigators, the planned operative date should be re-evaluated.

Secondary Outcome Measures
NameTimeMethod
Maximum Tolerated Dose (MTD) of palbociclib as determined by number of participants with dose limiting toxicities (DLT)up to 15 weeks

Maximum tolerated dose will be determined by the maximum dose at which the least number of participants experience dose-limiting toxicity. The dose limiting toxicity is defined using the Common Terminology Criteria for Adverse Events (CTCAE).

Major Pathologic Responseup to 15 weeks

Major Pathologic Response (MPR) was defined as fewer than 10% viable tumor cells.

Objective response rate (ORR)up to 15 weeks

Proportion of participants with measurable disease at baseline and have been re-evaluated after at least 1 cycle of therapy with observed reduction in tumor burden as defined by RECIST and iRECIST criteria after 2 doses of Proportion of participants with measurable disease at baseline and have been re-evaluated after at least 1 cycle of therapy with observed reduction in tumor burden as defined by RECIST and iRECIST criteria after 2 doses of camrelizumab and palbociclib

Progression free survival(PFS)Up to 2 years

Proportion of participants who achieve progression free survival post treatment

Overall survival (OS)Up to 2 years

Proportion of participants who achieve survival post treatment
