Both males and females must agree to adequate birth control if conception is possible during the study and for 6 months after the last dose; in this case, patients must take a monthly pregnancy test for the duration of the study. Female patients are considered to not be of child-bearing potential if they have a history of tubal ligation or hysterectomy or are post-menopausal with a minimum of 1 year without menses. The methods that can achieve a failure rate of less than 1% per year when used consistently and correctly are considered as highly effective birth control methods. Such methods include: * combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation: * oral; * intravaginal; * transdermal * progestogen-only hormonal contraception associated with inhibition of ovulation: * oral; * injectable; * implantable. * intrauterine device (IUD); * intrauterine hormone-releasing system (IUS); * bilateral tubal occlusion; * vasectomised partner; * sexual abstinence. Additional inclusion criteria: \- Patients must agree to not donate blood during the study or for 90 days after the last dose of study treatment. Exclusion Criteria: * Any other prior therapy directed at the malignant tumor, including immunologic agents administered within 4 weeks prior to first dose of study drug * Major surgical procedures ≤ 28 days of beginning study treatment, or minor surgical procedures \< 7 days. No timeline window required for port-a-cath placement. * Patients who received radiotherapy must have completed and fully recovered from the acute effects of radiotherapy. A washout period of at least 14 days is required between end of radiotherapy and randomization. * History of any ≥ grade 3 hematological toxicity due to prior chemotherapy that persisted for more than 4 weeks. * Patient has uncontrolled hypertension according to CTCAE v. 5.0 * Grade \> 1 toxicity from prior therapy (except alopecia or anorexia) that contraindicates start of new treatment. * Patient has inability to swallow oral medications or patients with gastrointestinal disorders likely to interfere with absorption of the study medication. Note: Patient may not have a percutaneous endoscopic gastrostomy (PEG) tube or be receiving total parenteral nutrition (TPN). * Known central nervous system (CNS) disease other than neurologically stable, treated brain metastases - defined as metastasis having no evidence of progression or hemorrhage for at least 28 days after treatment (including brain radiotherapy). Must be off any systemic corticosteroids for the treatment of brain metastases for at least 14 days prior to enrollment. * Chronic assumption of drugs or other products with a narrow therapeutic index and known to be CYP3A4 substrates, or drugs or other products known to be moderate to strong inhibitors/inducers of CYP3A4 which cannot be discontinued 2 weeks prior to day -3 of dosing and withheld throughout the study until 2 weeks after the last dose of study drug. Co-administration of aprepitant or fosaprepitant during this study is prohibited. * Herbal preparations are not allowed throughout the study. These herbal medications include but are not limited to: St. John's wort, kava, ephedra (mahung), gingko biloba, dehydroepiandrosterone (DHEA), yohimbe, saw palmetto and ginseng, grapefruit and seville orange. Patients should stop using these herbal medications at least 7 days prior to first dose of study treatment. * Any known hypersensitivity or contraindication to the components of the study drugs. * Any of the following cardiac diseases currently or within the last 6 months: a. Unstable angina pectoris; b. Congestive heart failure; c. Acute myocardial infarction; d. Conduction abnormality not controlled with pacemaker or medication; e. Significant ventricular or supraventricular arrhythmias (patients with chronic rate- controlled atrial fibrillation in the absence of other cardiac abnormalities are eligible). * The patient has a personal history of any of the following conditions: syncope of cardiovascular etiology, ventricular arrhythmia of pathological origin (including, but not limited to, ventricular tachycardia and ventricular fibrillation), or sudden cardiac arrest. * Evidence of corrected QT interval (specifically QTc calculated using the Fridericia formula \[QTcF\]) \> 470 msec from a single electrocardiogram (ECG) performed at study entry or congenital or acquired long QT syndrome. * The patient has serious and/or uncontrolled preexisting medical condition(s) that, in the judgment of the investigator, would preclude participation in this study (for example, interstitial lung disease, severe dyspnea at rest or requiring oxygen therapy, severe renal impairment \[e.g. estimated creatinine clearance \<30ml/min\], history of major surgical resection involving the stomach or small bowel, or preexisting Crohn's disease or ulcerative colitis or a preexisting chronic condition resulting in baseline Grade 2 or higher diarrhea). * Pregnant or breast-feeding. Female patients should not breastfeed or store milk within 30 days of receiving the final dose of niraparib and abemaciclib. * Serious active infection at the time of study entry, or another serious underlying medical condition that would impair the ability of the patient to receive study treatment. * Presence of other active invasive cancers (except for definitively treated in-situ carcinomas \[e.g. breast, cervix, bladder, skin melanoma\], or basal or squamous cell carcinoma of the skin) within the past 24 months. * Psychological, familial, sociological, or geographical conditions that do not permit compliance with protocol. * Patients with myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML) or with features suggestive of MDS/AML. * Previous allogenic bone marrow transplant or double umbilical cord blood transplantation (dUCBT). * History of human immunodeficiency virus (HIV) infection. * History Active HBV or HCV infection.

Female patients should not breastfeed or store milk during the study treatment and within 30 days of receiving the final dose of niraparib and abemaciclib.
