Study of SLS009 (Formerly GFH009) a Potent Highly Selective CDK9 Inhibitor in Patients With Hematologic Malignancies and High-Risk Newly Diagnosed AML

Plain-language summary
SLS009 (formerly GFH009) is a potent and highly selective CDK9 inhibitor. In this study the safety, tolerability, and antitumor activity of single agent SLS009 are assessed in two dose escalation groups (Group 1 in patients with relapsed/refractory AML, Group 2 in patients with relapse/refractory lymphoma/CLL/SLL). The safety, tolerability, and antitumor activity of SLS009 in combination with venetoclax and azacitidine in patient with relapsed/refractory AML who have relapsed on or are refractory to venetoclax-based regimens are being assessed in five cohorts of the expansion Group 3. Groups 4 and 5 have been added to evaluate efficacy, safety, and tolerability of GFH009 in combination with venetoclax and azacitidine in newly diagnosed AML patients who are less likely to benefit from standard induction treatment with venetoclax plus HMA only regimens.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria
. Male or female ≥ 18 years. For Group 3 Cohorts 4 and 5 only male or female ≥18 years and pediatric patients 12-18 years and ≥40 kg body mass
. Written informed consent must be obtained prior to any screening procedures
. For AML, acute promyelocytic leukemia (APL) patients are not included in the study.
. Adequate hepatic function as evidenced by meeting all the following requirements:
. Measured or calculated (determined by the Cockcroft-Gault equation) serum creatinine clearance (CrCl) ≥ 60 mL/min (glomerular filtration rate can be alternative to CrCl) for adult patients or serum creatinine ≤ 1.5 x ULN; or if serum creatinine \> 1.5 x ULN, then serum creatinine clearance (CrCl) ≥ 50 mL/min (estimated by Cockcroft-Gault formula or other appropriate formula) for pediatric patients. Whether the value is calculated by equation or measured directly can be based on institutional standard practice.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Safety and Tolerability: Dose Limiting Toxicities (DLTs)
. Eastern cooperative oncology group (ECOG) performance status 0-2.
. The electrolytes and uric acid level need to be stable judged by investigators for at least 3 days before the first dose of GFH009 (Medical intervention is permitted).
Exclusion criteria
. Uncontrolled medical conditions such as hypertension (systolic blood pressure \> 160 mmHg and/or diastolic blood pressure \> 100 mmHg), a history of hypertensive crisis, or a history of hypertensive encephalopathy.
. History of previous exposure to any other CDK9 inhibitors.
. Known hypersensitivity to the study drug or excipients of the preparation or any agent given in association with this study.
. Severe cardiovascular disease within 6 months of study entry, including any of the following:
. Patients with prior treatment with cardiotoxic agents who have experienced drug induced cardiotoxicities during or after treatment, where cardiotoxic agents include but are not limited to anthracyclines (doxorubicin, daunorubicin, epirubicin, idarubicin, mitoxantrone); trastuzumab and trastuzumab based ADCs; tyrosine kinase inhibitors (sunitinib, imatinib); alkylating agents (cyclophosphamide).
. Patients who are on systemic antibiotics are eligible to participate as long as the antibiotics are not expected to have significant DDI with GFH009 (A list of approved concomitant medications will be provided to investigators. If any antibiotic is not included in the approved list, it can be discussed with the sponsor or designated CRO on a case-by-case basis).
. Active hepatitis B or hepatitis C virus infection. Patients with chronic HBV infection with active disease who meet the criteria for anti HBV therapy have to be on a suppressive antiviral therapy prior to enrollment.
. Concomitant medications that are strong CYP3A4 inhibitors or strong inducers within 7 days prior to the first dose. Avoid consumption of Seville orange (and juice), grapefruit or grapefruit juice, grapefruit hybrids, pomelos, star citrus fruits or St. John's wort within 7 days of first dose.
