Full description
This study is an open-label, multicenter, Phase 1/2 study with a Dose-Escalation phase (Phase 1) and an Expansion phase (Phase 2).
Dose-Escalation (Phase 1): The dose-escalation phase will follow a classical 3+3 design but the first patient (sentinel) will be treated at dose level 1 (0.015 mg/kg) for one cycle, and, if no Dose-Limiting Toxicities (DLTs) occur, at dose level 2 (0.032 mg/kg) from cycle 2 onwards. Once the patient 1 (sentinel) is allowed to enter dose level 2, two additional patients will be enrolled to complete the cohort at dose level 2, and the dose-escalation phase will continue the 3+3 design. DLTs will be assessed based on the safety observed in cycle 1 (28 days) for all patients except for patient 1 (sentinel) where DLT will be assessed on safety observed in cycle 1 (at dose level 1) and cycle 2 (at dose level 2). For the first trial patient (sentinel) a single cycle will be completed (28 days) at dose level 0.015 mg/kg. Doses will not be escalated before all patients entered at the current dose level have been treated and observed for at least one complete cycle (28 days) at the intended dose- cohort IDP-121 dose and the number of DLTs among those patients in their first cycle has been determined. Before each escalation, Clinical Investigators will be consulted as part of a cohort review meeting to review and discuss all data (including safety, PK, PD and efficacy data) and agree on a dose-escalation, as appropriate.
During the study, the Sponsor and Investigators may request that cohorts be enlarged or that intermediate doses between 2 planned escalation steps be explored based on all data existing at that time, including emerging safety and efficacy data and determinations of PK and PD. Also, the study will allow for alternative IDP-121 doses and/or schedules to be evaluated based on emerging data e.g., once a week dosing of IDP-121 (instead of twice a week). Data from all patients at all dose levels will be used to guide further dose-escalation or/and the MTD/RP2D.
Expansion-Phase (Phase 2): Additional 17 patients will be enrolled for treatment at the RP2D level to further study safety and evaluate efficacy. Patients will receive 28-day cycles up to a maximum of 12 cycles of treatment or until any IDP-121 treatment discontinuation criteria are met (disease progression, unacceptable toxicity, etc). Patients in the Expansion- Phase may include one or more tumor types from those evaluated in dose-escalation.

Patient is, in the investigator's opinion, willing and able to comply with the protocol requirements.
Patient has given voluntary written informed consent before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to their future medical care.
Patients diagnosed with chronic lymphocytic leukemia (CLL), B-cell lymphomas, and multiple myeloma (MM) who are ineligible to reveive the available treatments.
Adequate hematological or biochemical parameters as specified below
Left ventricular ejection fraction > 50% or above the Institutional Lower Limit of Normal (LLN), whichever is lower, determined by echocardiogram.
Exclusion criteria
Persistent clinically significant non-hematological toxicity related to previous treatments. The presence of alopecia and NCI-CTC grade <2 symptomatic peripheral neuropathy is allowed.
Pregnant or lactating women; men and women of reproductive potential* (as defined in the Appendix 2) who are not using effective contraceptive methods (combined hormonal contraception associated with inhibition of ovulation; progestogen-only hormonal contraception associated with inhibition of ovulation, intrauterine device, intrauterine hormone-releasing system, bilateral tubal occlusion, vasectomised partner, sexual abstinenence).
*A woman is considered of childbearing potential (WOCBP), i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. A man is considered fertile after puberty unless permanently sterile by bilateral orchidectomy.
History of any other neoplastic disease in the last five years (except basal cell carcinoma, skin epithelioma or carcinoma in situ of any site)
History of clinically significant hypotension.
History of clinically significant allergic or hyper-sensitivity reactions.
History or known clinically significant vascular disease or known high risk of vascular disease (as assessed by the treating physician) including (but not limited to):
Other relevant diseases or adverse clinical conditions:
Clinically significant or active infection.
Significant non-neoplastic liver disease (e.g., cirrhosis, active chronic hepatitis)
The patient is known to be human immunodeficiency virus (HIV) positive, unless the patient is on antiviral therapy with HIV RNA levels <50 copies/mL; Hepatitis B surface antigen-positive or active hepatitis C infection, unless treated with undetectable hepatitis B DNA or hepatitis C RNA levels; or active CMV infection (IgM positive).
Concomitant anti-tumor therapy within 14 days prior to Day 1 of Cycle 1.
Prior allogeneic transplantation in the last 3 months or currently active GVHD with immunosuppressive treatment
Limitation of the patient's ability to comply with the treatment or follow-up protocol.
If a COVID-19 vaccine is administered, it should be done >72 hours prior to study treatment initiation or after the completion of the dose-limiting toxicity (DLT) period (if patient is participating in the dose-escalation phase").
