(Appendix 1)
4. Measurable extramedullary disease by any imaging modality (at least one site of

radiotherapy). Presence of biochemical measurable disease is not required. 5. Have received at least 2 prior lines of therapy including a PTI and an IMiD. Patient
must have undergone at least 1 complete cycle of treatment for each line of therapy,
unless PD was the best response to the line of therapy (Appendix 2) Note: induction
with or without haematopoietic stem cell transplant, consolidation and maintenance
therapy is considered a single line of therapy.
6. Have an ECOG Performance Status score of 0 or 1 (Appendix 3)
7. Have a life expectancy of ≥3 months, as judged by the Investigator. 8. Able to undergo apheresis for mononuclear cell collection. 9. Have clinical laboratory values meeting the following criteria within 7 days prior to
registration (enrolment):
- - Haemoglobin ≥80g/L (recombinant human erythropoietin use is permitted)
- ANC ≥1 × 109/L (prior growth factor support is permitted but must be without
support in the 7 days prior to the laboratory test)
- Platelet count ≥50 × 109/L.
- - Absolute lymphocyte count ≥0.3 × 109/L.
- - Total bilirubin ≤2.0× ULN; except in patients with congenital bilirubinaemia,
such as Gilbert's syndrome (in which case direct bilirubin ≤2.0× ULN is required)
- Calculated CrCl ≥40mL/min calculated by the Cockcroft-Gault formula (Appendix 4),
nuclear medicine assessment or a 24-hour urine collection.
10. When a woman is of childbearing potential, the patient must commit either to
abstaining continuously from heterosexual intercourse or agree to practice 2 methods
of reliable birth control simultaneously. Where one of the methods is highly effective
method of contraception (failure rate of <1% per year when used consistently and
correctly; see examples below) and one other effective method (i.e., male latex or
synthetic condom, diaphragm, or cervical cap) and patient must agree to remain on both
methods from the time of signing the PICF until at least 1 year after receiving a
cilta-cel infusion (Appendix 5). Reliable contraception is indicated even where there
has been a history of infertility, unless it is due to hysterectomy. WOCBP should be
referred to a qualified provider of contraceptive methods, if needed. Examples of
highly effective contraceptives include:
- - User-independent methods: 1) implantable progestogen-only hormone contraception
associated with inhibition of ovulation; 2) intrauterine device; intrauterine
hormone-releasing system; 3) vasectomised partner.
- - User-dependent method: progestogen-only hormone contraception associated with
inhibition of ovulation (oral or injectable)

man who is sexually active with a WOCBP or a pregnant woman must agree to use a
barrier method of contraception (e.g., latex or synthetic condom with spermicidal
foam/gel/film/cream/suppository) from the time of signing the PICF until at least 1
year after receiving a cilta-cel, even if they have undergone a successful vasectomy. 12. Women and men must agree not to donate eggs (ova, oocytes) or sperm, respectively,
until at least 1 year after receiving a cilta-cel infusion. 13. Patient must be willing and able to adhere to the following lifestyle restrictions
