BMS-986253 in Myelodysplastic Syndromes

A Phase I/II Trial of BMS-986253 in Myelodysplastic Syndromes

Background:

The myelodysplastic syndromes (MDS) are a group of bone marrow neoplasms. MDS mostly affect elderly people. The drugs used to treat MDS are not always effective, and the only curative treatment is stem cell transplant. Researchers want to see if a new drug can be used to treat MDS.

Objective:

To learn if HuMax-interleukin 8 (IL-8) BMS-986253 is a safe and effective treatment for MDS.

Eligibility:

Adults aged 18 and older with MDS.

Design:

Participants will be screened with a medical history, medication review, and physical exam. They will answer questions about how well they are able to take care of themselves. Their temperature, blood pressure, breathing rate, and heart rate will be monitored. They will have an electrocardiogram to see how well their heart is working. They will give blood and urine samples. They may have a bone marrow biopsy.

Participants will be assigned to a specific group. They will receive either BMS-986253 alone or in combination with deoxyribonucleic acid (DNA) methyltransferase inhibitors (DNMTi).

Treatment will be given in 28-day cycles. Participants will get BMS-986253 as an infusion on days 1 and 15 of each cycle. Some participants also will take oral DNMTi on days 2-6 of each cycle. They will receive treatment until their disease gets worse or they have bad side effects.

At study visits, some screening tests will be repeated. Some of the samples that are collected will be used for genetic testing.

About 30 days after treatment ends, participants will have a follow-up visit to see how they are doing. After that, follow up will occur via phone every 3-6 months until the study ends.

National Institutes of Health (NIH) will cover the costs for some travel expenses....

• Intervention / Treatment: Drug: Deoxyribonucleic acid (DNA) methyltransferase inhibitors (DNMTi) Decitabine; Drug: Deoxyribonucleic acid (DNA) methyltransferase inhibitors (DNMTi) Cedazuridine; Drug: BMS-986253; Procedure: Bone Marrow Biopsy; Procedure: Bone Marrow Aspiration; Procedure: ECG

Detailed Description

Background:

The myelodysplastic syndromes (MDS) are a group of clonal bone marrow neoplasms characterized by ineffective hematopoiesis, cytopenia, and high risk for transformation to acute myeloid leukemia (AML).

MDS is primarily a disease of the elderly, with about 80% of participants being older than 65-years of age; with 10,000 new diagnoses per year in the United States (U.S.)

The only curative treatment for participants with MDS is allogeneic hematopoietic stem cell transplantation (HSCT) and only a small portion of participants are eligible. Depending on risk stratification, the median survival of high- and low-risk MDS participants is 1.5 to 5.9 years, respectively.

Deoxyribonucleic acid (DNA) methyltransferase inhibitors (DNMTi) are the standard of care therapy for high-risk MDS. However, less than half of participants respond to DNMTi, and even the best responses are transient and non-curative. More effective and less toxic therapies are needed.

Interleukin-8 (IL-8) is a proinflammatory chemokine from the chemokine (C-X-C motif) CXC family and a potent chemoattractant of granulocytes and related cells to the site of inflammation. IL-8 is uniquely upregulated and found at high levels in both the peripheral blood and bone marrow aspirates of MDS participants. In purified MDS/Acute myeloid leukemia (AML) long-term/short term stem cells and granulocyte-macrophage progenitor cells both IL-8 and the IL-8 receptor, CXCR2, are overexpressed.

Preclinical data showed that CXCR2 inhibition led to significantly reduce proliferation of leukemic cell lines. In addition, MDS cluster of differentiation 34 (CD34+) cell cultures treated with neutralizing anti-IL-8 showed improvement in erythroid colony formation.

BMS-986253 is a fully human Immunoglobulin G1 (IgG1) neutralizing antibody that showed a favorable safety profile in participants with advanced solid tumors.

Concomitant treatment with DNMTi and BMS-986253 may improve treatment responses in participants with MDS by attenuating chemoattraction of myeloid derived suppressor cells to the bone marrow, indirectly disinhibiting natural killer (NK)- and T-cell responses against MDS stem cells, reducing neoangiogenesis, and improving cytopenia.

Objectives:

Primary objectives:

Phase I: To determine the optimal biological dose (OBD) and recommended phase 2 dose (RP2D) of BMS-986253 with or without DNMTi (decitabine and cedazuridine) therapy in MDS participants, and to describe the safety and tolerability of BMS-986253.

Phase II: To determine overall response rate (ORR) to BMS-986253 with or without DNMTi (decitabine and cedazuridine) therapy in MDS, measured according to the proposed revised International Working Group (IWG) 2018 response criteria.

Eligibility:

Participants must have histologically or cytologically confirmed MDS according to 2016 World Health Organization (WHO) criteria and

• have higher risk (HR) MDS Revised International Prognostic Scoring System (R-IPSS >= 3.5) and received a minimum of 2 and maximum of 8 cycles of DNMTi for Phase I (and a maximum of 4 cycles for Phase 2), or
• have lower risk (LR) MDS (R-IPSS <3.5) and at least one cytopenia (for both Phases I and II).

Age >=18 years

Eastern Cooperative Oncology Group (ECOG) performance status <=2 (KPS >= 60%)

Design:

This study consists of two phases:

Phase I: safety evaluation with determination of optimal biological dose (OBD) of BMS-986253 with or without DNMTi (decitabine and cedazuridine), and

Phase II: efficacy evaluation of BMS-986253 with or without DNMTi (decitabine and cedazuridine)

In both Phase I and II, participants will be enrolled into two cohorts:

A) Higher-risk cohort (HR-MDS), including high-risk and higher intermediate-risk disease, defined as those with R-IPSS >= 3.5: treatment with BMS-986253 in combination with DNMTi (decitabine and cedazuridine)

B) Lower-risk cohort (LR-MDS), including low-risk and lower intermediate-risk disease participants, defined as those with R-IPSS <3.5: treatment with BMS-986253 given as monotherapy

For Phase I, the safety endpoint will be dose limiting-toxicity (DLT) by D28 with the objective of defining the OBD and RP2D for BMS-986253. In addition, follow up for safety will be assessed 100 days after the end of the treatment cycle. For Phase II, the primary endpoint will be overall response rate after 6 cycles, reported separately by cohort.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Phase I: Optimal Biological Dose (OBD) for Human Humax (HuMax)-Interleukin 8 (IL-8) (BMS-986253)	OBD of BMS-986253 with and without deoxyribonucleic acid (DNA) methyltransferase inhibitors (DNMTi), as determined by dose limiting toxicity (DLT) occurring by cycle 1 day 28 (C1D28). DLT is defined as any of the following: any grade ≥ non-hematologic toxicity that is possibly, probably, or definitely related to study drug. Liver injury as defined by a positive Hy's Law. And adverse reaction that leads to dose reduction or withdrawal. OBD is the lowest tolerated dose level showing optimal biological activity, defined as maximal suppression of serum free IL-8 levels. The goal is to achieve IL-8 levels below the lower limit of detection of the assay in real time by Ultrasensitive immunoassay based on Quanterix Simoa technology. The lower limit of quantification = 0.86 pg/mL by Myriad-Rules Based Medicine (RBM).	First 28 days (C1D28) on up to 30 days.

A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.	From first study intervention, study day 1, through study day 100 after the end of the treatment cycle; approximately 7 months.
Phase I: Proportion of Participants With Dose-limiting Toxicities (DLT)	DLT is defined as any of the following: ang grade ≥ non-hematologic toxicity that is possibly, probably, or definitely related to study drug. Liver injury as defined by a positive Hy's Law. And adverse reaction that leads to dose reduction or withdrawal.	First 28 days
