Treatment for relapsed or refractory aggressive B-cell non-Hodgkin lymphoma

An Open Label, Phase 2 Clinical Trial of MEN1703 as Monotherapy and in Combination With Glofitamab in Patients With Relapsed or Refractory Aggressive B-cell Non-Hodgkin Lymphoma

Phase 2 Interventional Ryvu Therapeutics SA · NCT06534437

This study is testing a new treatment called MEN1703, alone and with another drug, to see if it helps people with aggressive B-cell non-Hodgkin lymphoma who haven't responded to other treatments.

What this trial studies

This study evaluates the safety and effectiveness of MEN1703 (Dapolsertib hydrochloride) as a treatment for patients with relapsed or refractory aggressive B-cell non-Hodgkin lymphoma. Participants will be divided into two groups: one group will receive MEN1703 combined with glofitamab, while the other group will receive MEN1703 alone. The treatment duration varies based on the patient's response, with a maximum of 12 cycles for the first group. The study aims to determine the best treatment approach for patients who have not responded to previous therapies.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with relapsed or refractory aggressive B-cell non-Hodgkin lymphoma who have received at least two prior lines of systemic treatment.

Not a fit: Patients with primary central nervous system lymphoma or those who have CNS involvement by lymphoma will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new option for patients with aggressive B-cell non-Hodgkin lymphoma who have limited treatment alternatives.

How similar studies have performed: Other studies have shown promise with similar treatment approaches, but this specific combination is being evaluated for the first time.

Eligibility criteria

Inclusion Criteria:

1. Age ≥18 years old
2. Documented histological confirmation of aggressive B-cell non-Hodgkin lymphoma including DLBCL NOS and transformed indolent B-cell lymphoma
3. Relapsed or refractory disease having received at least 2 prior lines of systemic treatment and, naïve to anti-CD3xCD20 bispecific antibody treatment (group 1) or exhausted all standard, available treatment options (group 2)
4. At least 1 measurable site of disease based on computed tomography (CT) or positron emission tomography (PET)-CT scan with involvement of 2 or more clearly demarcated lesions and or nodes.
5. Availability of lymph node tissue at Screening (or archival sample) (part 2 participants only)
6. Life expectancy of ≥12 weeks.
7. Eastern Cooperative Oncology Group (ECOG) Performance Status 0, 1 or 2

2. Received anti-cancer treatments, including cytotoxic chemotherapy, radiotherapy, hormonal therapy, biologic, immunotherapy, or investigational drugs within 14 days or 5 half-lives (whichever is shorter) before the first dose of study drug. Prior treatment with CAR-T cell or an anti-CD3xCD20 bispecific antibody therapy (permitted for Group 2 only), requires a wash out period of ≥4 weeks.
3. Concurrent participation in another therapeutic clinical study.
4. Ongoing clinically significant toxicity (for example, alopecia is not clinically significant) from any prior anti-cancer therapy that has not resolved to Grade 1 or less prior to the first dose of study drug.
5. Prior treatment with a PIM inhibitor.
6. Group 1 only: Any prior therapy with a bispecific antibody targeting CD3 and CD20.
7. Known risk of allergy to the study drugs, MEN1703 (group 1 and 2) or glofitamab (group 1) or their excipients
8. Contraindication to all uric acid lowering agents.
9. Major surgery within 1 month prior to first dose of study drug.
10. Hematopoietic stem cell transplant within 4 months prior to first dose of study drug.
11. Requires systemic immune-modulating therapy (regardless of dose) or has confirmed history or current autoimmune disease or other diseases resulting in permanent immunosuppression.
12. Exposed to live or live attenuated vaccine(s) within 4 weeks prior to signing the informed consent form (ICF).
13. Evidence of ongoing and uncontrolled systemic bacterial, fungal, or viral infection, except for documented Grade Common Terminology Criteria for Adverse Events (CTCAE) ≤2 infections with evidence of improvement or without evidence of worsening infection.
14. Known human immunodeficiency virus (HIV) infection
15. Current active liver disease from any cause
16. Ongoing drug-induced pneumonitis.
17. Ongoing inflammatory bowel disease.
18. Active known second malignancy
19. Received an agent known to be a sensitive CYP2D6 substrate or a CYP2D6 substrate with a narrow therapeutic range, a strong or moderate CYP2D6 inhibitor, or a BCRP inhibitor within 14 days or 5 half-lives (whichever is shorter), prior to the first dose of study drug.
20. Cardiac dysfunction is defined as myocardial infarction within 6 months of study entry, New York Heart Association (NYHA) Class III or IV heart failure, uncontrolled dysrhythmias, or poorly controlled angina.
21. Receiving treatment for active, ongoing thromboembolic event. Note: Does not apply to prophylactic treatment to prevent or avoid reoccurrence of a prior resolved event. To review with Medical Monitor where further risk assessment is needed.
22. History of serious ventricular arrhythmia (e.g., VT or VF, ≥3 beats in a row), or QT interval corrected for heart rate (QTc) ≥480 ms.

    Note: QTc values up to 500 ms will be acceptable where patient's medical history e.g., bundle branch block, is known to cause mild QTc prolongation and the condition is well controlled.
23. Any disease, syndrome or condition which may significantly affect drug intake via oral route.
24. Planning to become pregnant or breastfeed during treatment and for 1 month after the last dose of study drug.
25. Any other prior or current medical condition, intercurrent illness, surgical history, physical or 12-lead electrocardiogram (ECG) findings, laboratory abnormalities, or extenuating circumstance (e.g., alcohol or drug addiction) that, in the investigator's opinion, could jeopardize patient safety or interfere with the objectives of the study.
