Overview of the studies
The source data includes three interventional trials of Annamycin, also called liposomal Annamycin or L-Annamycin in the trial titles and summaries.[1][2][3] These studies are in adults with cancer and focus on two main diseases: acute myeloid leukemia and metastatic soft-tissue sarcomas.[1][2][3]
The trials are designed to learn about safety, tolerability, dose selection, and early signs of benefit.[1][2][3] Two studies use Annamycin with cytarabine, which is another cancer drug named in the source data, and one study tests liposomal Annamycin alone in sarcoma.[1][2][3]
Studies in acute myeloid leukemia
Two trials in the source data study acute myeloid leukemia (AML).[2][3] One is a Phase 2/3 multi-center study in adults with refractory or relapsed AML, meaning the disease did not respond to treatment or came back after treatment.[2] The other is a Phase 1 study that evaluates safety, efficacy, and tolerability of liposomal Annamycin with cytarabine in patients with AML.[3]
The larger AML study compares L-Annamycin plus cytarabine with placebo plus cytarabine as second-line therapy, which means treatment given after the first treatment did not work well enough.[2] Its Part A looks for the best dose regimen, and Part B tests whether the chosen dose works better than placebo when both are given with cytarabine.[2]
The Phase 1 AML study also includes patients who are refractory to or relapsed after induction therapy, and the brief summary says it also considers first-line therapy in the source data.[3] This trial aims to find the maximum tolerated dose and the Recommended Phase 2 Dose, which are study terms for choosing a dose that is workable and can be tested further.[3]
Study in metastatic soft-tissue sarcoma
The sarcoma trial is a Phase 1b/2 study in patients with metastatic soft-tissue sarcomas after failure of at least one systemic therapy.[1] Systemic therapy means treatment that travels through the body, such as treatment given by vein or by mouth, although the source data does not list all prior treatments.[1]
This study tests weekly liposomal Annamycin as monotherapy, which means it is given by itself rather than with another anticancer drug.[1] The Phase Ib part is designed to establish safety and tolerability and to determine the Recommended Phase 2 Dose.[1] The Phase II part measures 3-month progression-free survival, a way to see whether the cancer stays from getting worse for at least three months.[1]
What the trials measure
The main outcomes in these studies are different, but they all help researchers judge whether the treatment is promising.[1][2][3] In the sarcoma study, the key outcomes are safety, tolerability, dose choice, and 3-month progression-free survival.[1] In the AML studies, the trials measure complete remission, dose selection, and in one study whether the patient may be eligible for hematopoietic stem cell transplantation.[2][3]
The AML Phase 1 study gives a detailed definition of complete remission in the source data: normal bone marrow appearance with fewer than 5% blasts, plus recovery of blood counts.[3] It also defines complete remission with incomplete recovery as CR with incomplete recovery of platelets and/or neutrophils, and partial response as a 50% or greater decrease in marrow blasts.[3]
The Phase 2/3 AML study uses the rate of CR after one treatment cycle as its main outcome, measured about 35 days plus or minus 14 days after treatment starts.[2] This kind of endpoint helps show how many people respond after the first cycle of treatment.[2]
Who may join these trials
The source data shows that the trials are for adult subjects with specific cancers.[2][3] The AML studies include adults with refractory or relapsed AML, while the sarcoma study includes patients with metastatic soft-tissue sarcomas after at least one prior systemic therapy.[1][2][3]
These are not general cancer studies for all patients. Each trial focuses on a specific disease group and treatment history, so people need to match the study rules listed in the trial data.[1][2][3]
Trial phases and study size
The trials cover early and later research stages.[1][2][3] The sarcoma study is Phase 1b/2 with 30 planned participants, the Phase 1 AML study has 24 participants, and the Phase 2/3 AML study plans 312 participants.[1][2][3]
The source data also lists the Phase 2/3 AML study as Phase 4 in the phase field, so the trial record contains a phase label that does not fully match the title.[2] In patient-friendly terms, this means the study record should be read carefully because different parts of the source data do not use the same phase label.[2]
Important terms explained
Liposomal means the drug is placed in a tiny fat-like carrier, which is how the trial names describe Annamycin in these studies.[1][2][3] Monotherapy means one drug is used by itself.[1]
Second-line therapy means treatment used after the first treatment does not work well enough or the disease returns.[2] Stem cell transplantation is a treatment approach mentioned in the Phase 1 AML study as an eligibility outcome, meaning the study checks whether a subject is fit enough for that next step of care.[3]
Interventional means the researchers give a treatment and then measure the results.[1][2][3] Authorised and completed are study status labels in the source data that show whether a trial is open for use or already finished.[1][2][3]
