Criteria

Inclusion Criteria:

1. age >= 18 years

2. positive PCR COVID-19 test (max. 72h old)

3. known vaccination status

4. ANC >= 1,000/mm3 and platelets >= 50,000/mm3

5. willingness to participate (written informed consent)

6. established risk factors for a severe course of COVID-19-disease, for example:

adipositas, cardiovascular disease including arterial hypertension, advanced age > 60, chronic lung disease including asthma, diabetis type I or II, chronic kidney disease, chronic liver disease

7. Oxygen supply: ≤ 2 liters/minute

8. Women of childbearing potential (WOCBP): must have a negative pregnancy test (ß- HCG urine or serum test) a. WOCBP is considered as i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile.

b. Permanent sterilization methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy.

c. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause.

9. Use of highly effective contraception method

1. All potentially fertile participants, or their male partners, must use an adequate, medically approved method of contraception or agree to abstinence during and at least 3 weeks (females) and 14 weeks (males) after treatment with Palbociclib.

2. For females, highly effective birth control should be used, i.e., combined hormonal contraception associated with inhibition of ovulation (oral, intravaginal, or transdermal), progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, or implantable), intrauterine device, or intrauterine hormone-releasing system, bilateral tubal occlusion and vasectomized partner. As there is no information available on the interaction of palbociclib with oral contraceptives, a double-barrier contraception is necessary in this case.

3. Males must agree to use a condom for at least 14 weeks after the treatment phase.

Exclusion Criteria:

1. age < 18 year

2. ECOG >= 3

3. ANC < 1,000/mm3 and platelets < 50,000/mm3

4. intensive care patient

5. treatment with any other CDK4/6 Inhibitor

6. pregnant or breast-feeding women

7. patients receiving immunosuppressants for other diseases (e.g. rheumatoid arthritis)

8. known malignancy in the past 5 years other than basal cell carcinoma

9. baseline O2-Saturation < 92%

10. participation in any other medical device or medicinal product study within the previous month
