Brief summary: The efficacy and safety of Pazopanib combined with Palbociclib in the third line and above treatment of refractory solid tumors co amplified in the 11q13 region (FGF3/4/19/CCND1).

Detailed description: Based on literature review, this study first conducted a phase Ib study to observe the dose limiting toxicity (DLTs) of the combination therapy of pazopanib and palbociclib and to determine the recommended dose for phase II study (RP2D); Further phase II studies will be conducted to evaluate the efficacy of pazopanib combined with palbociclib in the third line and above treatment of refractory solid tumors co amplified in the 11q13 region using objective response rate (ORR) or progression free survival 2/progression free survival 1 (PFS2/PFS1). And observe and evaluate the progression free survival (PFS), time to remission (TTR), disease control rate (DCR), and overall survival (OS) of pazopanib combined with palbociclib for third line and above treatment of refractory solid tumors co amplified in the 11q13 region. Evaluate the safety of Pazopanib combined with palbociclib for the third line and above treatment of refractory solid tumors co amplified in the 11q13 region.
