Study of MK-1045 alone or with Tocilizumab in patients with Non‑Hodgkin Lymphoma to evaluate safety and efficacy

1 1 1

What is this study about?

Non-Hodgkin Lymphoma is a type of blood cancer that starts in the lymphatic system, which helps fight infection. The study is testing a new medicine called MK-1045. This drug may be given directly into a vein (intravenous) or injected under the skin (subcutaneous), and in some groups it may be combined with other cancer medicines.

The main aim of the study is to find out whether the medicine is safe and can help shrink or control the cancer. Participants will be placed into different groups that receive the drug in one of the ways described, and they will have regular visits where doctors check for side effects, take blood samples, and perform imaging scans to see how the disease is responding. The study will follow each person for several months to monitor health and any changes in the cancer.

1 consent and enrollment

after joining the study you will read a detailed information sheet and sign a consent form that explains the purpose of the trial and your rights.

your participation is recorded and you become an enrolled participant for the study.

2 baseline assessments

the study team will collect your medical history, perform physical examinations, and take blood samples to evaluate organ function.

imaging tests such as scans will be done to document the extent of non-hodgkin lymphoma before treatment begins.

3 first dose of <b>mk-1045</b>

you will receive the first administration of mk-1045 according to the arm you are assigned to.

if you are in arm 1, 2, or 4 the drug is given by intravenous (iv) infusion; if you are in arm 3 it is given by subcutaneous (sc) injection.

the exact dose amount, infusion rate, and injection volume are defined by the study protocol and will be followed by the clinical staff.

4 continued treatment cycles

additional doses of mk-1045 are given at regular intervals set by the protocol, typically every few weeks.

each cycle includes the same method of administration (iv or sc) as the first dose and continues for the number of cycles specified in the study plan.

5 safety monitoring

before each dose you will have vital signs checked and blood drawn to monitor organ function.

the study staff will ask about any new symptoms and record any adverse events that occur.

if a serious problem such as dose limiting toxicity (dlt) is identified, treatment may be paused or stopped according to protocol guidelines.

6 efficacy evaluation

periodic imaging scans are performed to assess tumor response using the lugano response criteria.

in arms 1 and 4 the response is reviewed by a blinded independent central review, while in arms 2 and 3 the investigator or designated reviewer evaluates the results.

the primary measurement of effectiveness is the objective response rate (orr), and the length of time the response lasts is called the duration of response (dor).

7 treatment completion

treatment ends after the pre‑specified number of cycles have been administered or earlier if a discontinuation criterion such as an adverse event is met.

a final set of safety labs and imaging studies is performed to document the status at the end of treatment.

8 post‑treatment follow‑up

after treatment stops you will continue to have regular visits for safety checks and to monitor disease status.

follow‑up visits may include blood tests and imaging at intervals defined by the protocol, extending for several weeks or months after the last dose.

Who Can Join the Study?

Must have Non‑Hodgkin Lymphoma that has come back (relapsed) or did not respond (refractory) after at least two different rounds of standard drug treatment.
Must have a diagnosis confirmed by looking at tissue under a microscope that the cancer is either follicular lymphoma or diffuse large B‑cell lymphoma (DLBCL).
If the cancer is DLBCL, you must have either progressed after a stem‑cell transplant or not be able to receive a transplant, and you must also have tried or be unable to receive CAR‑T cell therapy (a type of treatment that uses modified immune cells).
Must have provided a sample of tumor tissue (either from past records or a new biopsy done as part of regular care).
If you have previously received a treatment that targets CD19 (a protein on the cancer cells) and the disease got worse, a new biopsy must show that the tumor still has CD19 present.
If you have a history of HIV, the virus must be well‑controlled while you are on antiretroviral therapy (medications that keep HIV suppressed).
If you test positive for hepatitis B surface antigen (HBsAg), the hepatitis B virus must have an undetectable amount in your blood and you must be taking and continue to take hepatitis B antiviral medication.
If you have a history of hepatitis C, the hepatitis C virus must be undetectable in your blood and you must be receiving hepatitis C antiviral treatment.
You must have disease that can be measured on imaging scans according to the Lugano Response Criteria (a set of rules doctors use to assess lymphoma size and changes).
Both men and women are eligible to join the study.
People of any age group are allowed to participate.

Who Cannot Join the Study?

Trial locations

Investigated drugs:

Tocilizumab

Tocilizumab is a medication that blocks a protein called interleukin‑6, which can help reduce inflammation. In this study it is mentioned as a background reference, meaning it is not the main drug being tested but is provided for context about other treatments that affect the immune system.

MK-1045 is an experimental therapy being studied for people with Non‑Hodgkin Lymphoma. It is given either by an intravenous (IV) infusion or a subcutaneous (under the skin) injection. The trial is looking at how safe it is, how well patients can tolerate it, and whether it can shrink or control the cancer. The drug is tested alone, without other cancer medicines, to see its direct effect on the disease.

Non-Hodgkin Lymphoma – A type of cancer that begins in the white‑blood cells of the lymphatic system, which helps fight infection. It usually starts in lymph nodes but can also arise in the spleen, bone marrow, or other organs. The abnormal cells multiply and form tumors that may enlarge the affected lymph nodes. Over time the disease can spread to nearby tissues or distant parts of the body. The speed of growth can vary, with some forms progressing slowly and others advancing more quickly. Symptoms often develop as the tumors enlarge or affect organ function.
