Criteria

Inclusion criteria

• Age >18 years

• Histologically confirmed (according to the WHO 2016 classification) mantle cell lymphoma stage I-IV

• Who have received at least 1 prior rituximab-containing chemotherapy regimen, with documented relapse or disease progression following the last anti-MCL treatment OR

• Are not considered to be candidates for chemotherapy due to frailty or comorbidity

• At least 1 measurable site of disease (>1.5 cm long axis)

• WHO performance status 0 - 3

• Written informed consent.

• Female subjects of childbearing potential must (see page 52 for definition of not fertile):

• Understand that the study medication is expected to be teratogenic

• Agree to use, and be able to comply with, highly effective contraception without interruption, 4 weeks before starting study drug, throughout study drug therapy (including dose interruptions) and for 4 weeks after the end of study drug therapy, even if she has amenorrhoea.

• All fertile women must agree to perform monthly pregnancy tests while on study medication and until 4 weeks after completion of study drug. Tests must have a minimum sensitivity of 25 mIE/ml and be medically witnessed

• Highly effective contraception include:

Implant* Levonorgestrel-releasing intrauterine system (IUS)* Medroxyprogesterone acetate depot Tubal sterilisation Sexual intercourse with a vasectomised male partner only; vasectomy must be confirmed by two negative semen analyses Ovulation inhibitory progesterone-only pills (i.e., desogestrel) NB! Patients using a hormonal method, must also use a second barrier method. Sexual abstinence (if refraining from heterosexual intercourse during the entire period of risk associated with the study treatments. The reliability of sexual abstinence needs to be evaluated in relation to the preferred and usual lifestyle of the subject).

• Male subjects must

• Agree to use condoms throughout study drug therapy, during any dose interruption and for one week after cessation of study therapy if their partner is of childbearing potential and has no contraception.

• Agree not to donate semen during study drug therapy and for one week after end of study drug therapy.

• All subjects must

Subjects with Gilbert's Syndrome may have a bilirubin > 1.5 × ULN, per discussion between the investigator and medical monitor. Elevated Bilirubin due to haemolytic anemia or caused by lymphoma, is not an exclusion criterion.
