Brief summary: Homologous Recombination Repair (HRR) gene mutations can be detected in many solid tumors, patients with HRR gene mutations may benefit from PARP inhibitor. Antiangiogenic drugs can induce hypoxia and increase the sensitivity to PARP inhibitor. The combination of PARP inhibitor and antiangiogenic drug can play a synergistic anti-tumor role and achieve good efficacy in HRR gene-mutated tumors. The purpose of the study is to determine the dose limiting toxicity (DLT) and maximum tolerable dose (MTD) of Niraparib plus Anlotinib in HRR gene-mutated advanced solid tumors, and evaluate the safety and effectiveness of this combination therapy preliminarily.

Detailed description: This is a single-arm, single-center, phase I study to investigate the DLT and MDT, safety and efficacy of Niraparib combined with Anlotinib in the treatment of advanced solid tumors with HRR gene mutations. In this study, 52 histological or cytological diagnosis, previous treatment failure patients of HER2 negative breast cancer, cholangiocarcinoma, gastric adenocarcinoma and pancreatic cancer are included and receive Niraparib combined with Anlotinib. Patients are required to carry pathogenic or suspected pathogenic gBRCA or sBRCA mutations, or HRR gene mutations defined by the inclusion criteria. The study will be divided into two phase. The first phase will include 6-12 patients on a 21-day cycle to determine the DLT and MTD. In the second phase, 40 patients will be included to treated with Niraparib plus Anlotinib until disease progression or intolerable toxicity or withdrawal of the trial.

Eligibility criteria: Inclusion Criteria:

* Subjects understand the trial process, sign informed consent, agree to participate in the study, and have the ability to follow the protocol;
* 18 \~ 70 years old
* HER2 negative breast cancer, cholangiocarcinoma, gastric adenocarcinoma and pancreatic cancer confirmed by histology or cytology meet any of the following conditions: first line treatment failure of HER2 negative breast cancer; first line treatment failure of cholangiocarcinoma; second line treatment failure of gastric adenocarcinoma; first line treatment failure of pancreatic cancer
* At least one measurable target lesion that meet RECIST 1.1 criteria
* Can provide paraffin-embedded tumor tissue samples or plasma samples for HRR gene detection
* Carry pathogenic or suspected pathogenic germline or somatic HRR gene mutations, HRR genes include BRCA1, BRCA2, ATM, ATR, BAP1, BRIP1, CHEK2, FANCA, PALB2 and RAD51, mutations in other HRR genes should be evaluated by researchers and the pathogenicity should be supported by published literature or clinical studies.

When liver metastases are present, it must be \<= 5 times the upper limit of normal value
* The toxic side effects of any previous chemotherapy have recovered to \<= CTCAE level 1 or baseline levels, except for sensory neuropathy or hair loss with stable symptoms \<= CTCAE level 2

Exclusion Criteria:

* People who are known to be allergic to Niraparib or Anlotinib (or active or inactive ingredients of drugs with similar chemical structure)

* Received palliative radiotherapy of \> 20% bone marrow 1 week before enrollment
* Have invasive cancer other than ovarian cancer (except fully treated basal or squamous cell skin cancer) within 2 years before enrollment
* Patients with tumor invasion of large vessels
* Previous or currently diagnosed myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML)
* Severe or uncontrolled diseases, including but not limited to: uncontrollable nausea and vomiting, inability to swallow or gastrointestinal diseases that may interfere with drug absorption and metabolism; active viral infections; mental illnesses that affect patients' signed informed consent History of bleeding tendency and thrombosis; history of severe cardiovascular disease
* Laboratory abnormalities: hyponatremia; hypokalemia; uncontrollable nail function abnormalities
* Receive platelet or red blood cell transfusions within 4 weeks
* Patients who are pregnant or nursing, or who plan to become pregnant during study treatment
* Have previously received any PARP inhibitor or Anlotinib treatment
