About
The goal of this clinical trial is to evaluate the safety and tolerability of escalating doses of LP-284 and to determine the maximum tolerated dose (MTD) and the recommended Phase 2 dose (RP2D) in patients with relapsed or refractory (R/R) lymphomas and solid tumors. The secondary objectives are to characterize the pharmacokinetics (PK) of LP-284 and to assess clinical activity of LP-284.
Full description
This FIH study is an open-label Phase 1a/1b dose escalation and dose expansion study in adult patients with R/R lymphoma and solid tumors. Patients who provide informed consent and meet the eligibility criteria for the study will be enrolled and treated with LP-284 administered intravenously (IV) on Days 1, 8, 15 of a 28-day schedule.
The study will be conducted in 2 parts: dose escalation with MTD and/or RP2D confirmation (Phase 1a) and dose expansion (Phase 1b). Up to 30 evaluable patients will be enrolled in Phase 1a; the total number of patients will depend on the number of dose levels explored. Up to 40 evaluable patients will be enrolled in each of the 2 cohorts of MCL and DLBCL tumors in Phase 1b.
Patients will remain on study treatment for up to a total of one-year OR until disease progression, unacceptable toxicity, withdrawal of consent, any study-specific discontinuation criteria are met, or the Investigator determines that it is in the best interest of the patient to discontinue study treatment, whichever is shorter.

For Lymphoma patients. At least one bi-dimensionally measurable disease site. The lesion must have a greatest transverse diameter of at least 1.5 cm and greatest perpendicular diameter of at least 1.0 cm at baseline. The lesion must be positive on positron emission tomography (PET) scan.

ii Total serum bilirubin ≤ 1.5 x ULN or < 5x ULN if secondary to Gilbert's syndrome or documented lymphoma involvement of liver.
Renal Function iii Serum creatinine clearance ≥60 mL/min, either measured or calculated using standard Cockcroft-Gault formula.
iv Serum electrolyte (potassium, calcium, and magnesium) levels within the normal reference range (may be supplemented according to institutional standards).
Bone Marrow Function:
v Absolute neutrophil count (ANC) ≥ 1500/μL. (Phase 1b: ANC ≥ 1000/μL if documented by investigator as the normal baseline for the patient) vi Hemoglobin ≥ 8 g/dL (for those patients undergoing red blood cell [RBC] transfusion, hemoglobin must be evaluated after at least 14 days after the last RBC transfusion).
vii Platelet count ≥ 100,000/μL (assessed ≥ 7 days following last platelet transfusion in patients with thrombocytopenia requiring platelets). (Phase 1b: ≥ 75,000/μL may be acceptable after discussion with the Sponsor)
Women of child-bearing potential (WOCBP) must agree to use highly effective contraceptive methods and avoid egg donation for the duration of study treatment and for 6 months after the last dose of study drug.
Women of child-bearing potential must have a negative serum pregnancy test at Screening and within 72 hours prior to the first dose of study drug.
Men must agree to use highly effective contraceptive methods and avoid sperm donation during the study treatment and for 3 months after the last dose of study drug if the partner is a WOCBP.
Phase 1a ONLY:
Histologically confirmed diagnosis of B-cell NHL according to the 2016 World Health Organization (WHO) classification that has relapsed from or is refractory to at least two prior standard of care treatments or tumors for whom standard therapies are not available. Diffuse large B-cell lymphoma (DLBCL) includes: DLBCL not otherwise specified (NOS) with or without MYC and BCL2 and/or BCL6 rearrangements; Epstein-Barr virus (EBV) positive DLBCL, NOS; human herpesvirus 8 (HHV8) positive DLBCL, NOS; DLBCL associated with chronic inflammation; and Primary cutaneous DLBCL, leg type. Patients with indolent lymphoma are eligible if they meet criteria for systemic treatment.
OR Histologically or pathologically confirmed advanced solid tumor that has relapsed from or is refractory to standard treatment, or for which no standard treatment is available.
Notes: Archival formalin fixed paraffin embedded (FFPE) tumor tissue is preferred but optional.
Patients with small lymphocytic lymphoma (SLL) are only eligible if they do not require immediate cytoreductive therapy or if they do not have available treatments with potential benefit.
Patients with solid tumors Only: Non-measurable or Measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 (Eisenhauer, 2009) for solid tumors at Screening.
Phase 1b ONLY
Histologically confirmed diagnosis of DLBCL or MCL according to the 2016 WHO classification. DLBCL includes: DLBCL not otherwise specified (NOS) with or without MYC and BCL2 and/or BCL6 rearrangements; Epstein-Barr virus (EBV) positive DLBCL, NOS; HHV8+ DLBCL, NOS; DLBCL associated with chronic inflammation; and Primary cutaneous DLBCL, leg type

Documented tumor alteration status. Archival (preferably collected within 6 months prior to first dose [C1D1]) FFPE tumor sample must be submitted for determination of genomic signature by Lantern Pharma's validated laboratory developed test regardless of whether a local test has been performed for enrollment.
