The potent CYP3A4 inihibitor posaconazole is allowed in patients participating in the posaconazole DDI part of the study. Following review of the posaconazole DDI data, and with the agreement of the Safety Review Committee, concomitant use of posaconazole may be permitted thereafter in the study. • CYP3A4 and/or CYP2B6 and/or P-gp and/or OATP1B1 sensitive substrates and substates with narrow therapeutic index taken within 2 weeks of the first dose of study treatment & during Cycle 1. Note - Patients may receive pravastatin or fluvastatin (with monitoring for potential toxicities), or atorvastatin or simvastatin at 10mg daily dose only. • CYP2C8 sensitive and moderate substrates taken within 2 weeks of the first dose of study treatment and duryng Cycle 1. • Herbal medications taken within 7 days of the first dose of study treatment (4 weeks for St John's wort) or while on study treatment. • Radiotherapy with a wide field of radiation or to more than 30% of the bone marrow within 4 weeks of the first dose of study treatment; palliative radiotherapy to ≤30% of the bone marrow within 2 weeks of the first dose of study treatment. • Steroids use >10mg daily (or 20mg daily for NHL) prednisolone or equivalent within 2 weeks of the first dose of study treatment. Replacement therapy steroids (even exceeding the above daily dose), given in the context of a transfusion, inhaled, nasal, topical and ophthalmic steroids are allowed. Note: For control of lymphoma related symptoms, patients may have received a brief (<7days) course of systemic steroids (≤ 100 mg prednisone equivalent per day) prior to initiation of study therapy. MM patients may receive >10mg daily if discussed and agreed with the medical monitor. • Medications with known risk of QT/QTc interval prolongation should be avoided concomitantly with CCS1477 unless essential in clinical management of the patient.

- Active or unresolved spinal cord compression or CNS infiltration.
- History of prior malignancy except for the following: • Adequately treated carcinoma in situ or non-melanomatous skin cancer • Malignancy treated with curative intent or in remission for >6 months after the last therapy may be eligible. Maintenance treatment is allowed. Note: Patients with a history of any haematological malignancy (other than indications included in the protocol) may be included following discussion with the medical monitor
- Any evidence of severe or uncontrolled systemic disease (e.g. current unstable or uncompensated respiratory or cardiac conditions; recent history of significant cardiac incidents, eg. significant cardiac dysfunction (congestive heart failure [NY Heart Association Class III or IV]; myocardial infarction within 12 months of starting study; unstable or poorly controlled angina pectoris) history of risk factors for torsades de pointes (e.g. heart failure, hypokalemia, family history of long QT syndrome or clinically significant arrhythmia; uncontrolled diabetes; history of, or active, bleeding diatheses; uncontrolled active systemic infection, including hepatitis B&C and human immunodeficiency virus (HIV), or active HBV, HCV, SARS-CoV2 (for patients receiving elranatamab or teclistamab) which in the investigator’s opinion makes it undesirable for the patient to participate in the study or which would jeopardise compliance with the protocol.
- Repeatable QTcF prolongation (>470 msec).
