Trial Summary
What is the purpose of this trial?
This trial is testing ASTX660, a new drug for patients with advanced cancers who have no other treatment options. It works by blocking proteins that help cancer cells survive, making it easier to kill them.
Will I have to stop taking my current medications?
The trial protocol does not specify if you must stop taking your current medications. However, you cannot take certain treatments like chemotherapy, radiotherapy, or monoclonal antibodies within a specific time before starting the trial. It's best to discuss your current medications with the trial team.
What safety data is available for ASTX660 in humans?
How is the drug ASTX660 unique for treating cancer?

Treatment Details
Interventions
- ASTX660
Trial OverviewASTX660 is being tested in this Phase 1/2 trial to find the safest dose, see how well it works against certain cancers, and understand its effects on the body. Participants will receive ASTX660 directly without comparison to another drug.
Participant Groups
9Treatment groups
Experimental Treatment
Group I: Phase 2 - Cohort 6Experimental Treatment1 Intervention
Treatment with ASTX660 for cervical carcinoma not responsive or relapsed after standard therapy.
Group II: Phase 2 - Cohort 5Experimental Treatment1 Intervention
Treatment with ASTX660 for other tumor types that are characterized by a molecular feature that may confer sensitivity to ASTX660 (eg, oncogenic activation of the NF-κB pathway or documented amplification of the gene loci encoding c-IAP1 or c-IAP2), pending confirmation in writing by the Astex medical monitor.
Group III: Phase 2 - Cohort 4Experimental Treatment1 Intervention
Treatment with ASTX660 for relapsed or refractory cutaneous T-cell lymphoma (CTCL).
Group IV: Phase 2 - Cohort 3Experimental Treatment1 Intervention
Treatment with ASTX660 for progressive or relapsed peripheral T-cell lymphoma (PTCL).
Group V: Phase 2 - Cohort 2Experimental Treatment1 Intervention
Treatment with ASTX660 for relapsed or refractory diffuse large B-cell lymphoma (DLBCL).
Group VI: Phase 2 - Cohort 1Experimental Treatment1 Intervention
Treatment with ASTX660 for recurrent/metastatic head and neck squamous cell carcinoma (HNSCC) not responsive or relapsed after standard therapy.
Group VII: Phase 1 - Part 3 (optional)Experimental Treatment1 Intervention
The purpose of the optional Part 3 is to allow for exploration of an alternative dosing regimen of ASTX660 based on emerging safety, PK, and pharmacodynamic (PD) data from Parts 1 and 2 (using the original every-other-week dosing regimen), with agreement of the DSRC. If Part 3 is conducted, the plan is to enroll up to 18 evaluable subjects in 1 or more cohorts using a standard 3+3 study design.
Group VIII: Phase 1 - Part 2 (completed)Experimental Treatment1 Intervention
Dose-expansion stage to confirm tolerability of ASTX660 at the RP2D using the every-other-week daily dosing regimen. Up to a total of 12 subjects (including the 3 or 6 subjects treated at the RP2D in Part 1) will be treated at the RP2D.
Group IX: Phase 1 - Part 1 (completed)Experimental Treatment1 Intervention
Dose-escalation stage to identify the MTD and the RP2D, defined as either the MTD or a dose below the MTD that the Data and Safety Review Committee (DSRC) agree shows adequate pharmacological evidence of target engagement and/or clinical activity. Subjects will receive ASTX660 once a day for 7 consecutive days every other week of each 28-day cycle (ie, \[7 days on/ 7 days off\] ×2; daily dosing on Days 1-7 and 15-21). The starting dose will be escalated stepwise in successive cohorts of 3 to 6 evaluable subjects each (standard 3+3 study design), until the RP2D is determined.

Findings from Research
A total of 3120 adverse event cases related to avapritinib were reported to the FDA, with 44% occurring within the first 30 days of treatment, highlighting the importance of monitoring patients closely during this period.
The study found that elderly male patients are at a higher risk for serious adverse events, indicating that clinicians should exercise caution when prescribing avapritinib to this demographic.

A post-marketing pharmacovigilance study of avapritinib: Adverse event data mining and analysis based on the United States Food and Drug Administration Adverse Event Reporting System database.Rong, L., Xie, M., Jiang, M., et al.[2023]
A meta-analysis of 53 Phase II/III/IV trials involving nearly 20,000 patients revealed that molecular target anticancer drugs significantly increase the risk of serious adverse events (SAEs) by 57% and fatal adverse events (FAEs) by 51% compared to placebo.
The overall incidence rates for SAEs and FAEs were found to be 26.9% and 2.3%, respectively, highlighting the need for careful monitoring and preventive measures for patients receiving these treatments.

Risk of serious adverse event and fatal adverse event with molecular target anticancer drugs in cancer patients: A meta-analysis.Wang, Z., Yang, X., Wang, J., et al.[2020]
A review of 12 targeted anticancer drugs revealed that 39% of serious adverse drug reactions (ADRs) and 39% of potentially fatal ADRs were not reported in the corresponding pivotal randomized clinical trials (RCTs), highlighting a gap in safety information for oncologists.
After a median of 4.3 years post-approval, 42% of these drugs received boxed warnings from the FDA, indicating that significant safety concerns can emerge long after initial approval and may not be adequately addressed in early clinical trial reports.
