The Phase 1b/2 study is a U.S. multi-center, open-label, single-arm study that in Phase 1b will determine the maximum tolerated dose (MTD) or the recommended Phase 2 dose (RP2D) and safety of Annamycin. The Phase 2 portion of the study will explore the efficacy of Annamycin as a single agent for the treatment of subjects with STS with lung metastases, who have failed prior chemotherapy, and for whom new chemotherapy is considered appropriate. A minimum of 3 subjects will be enrolled in each of up to 6 cohorts of the Phase 1b portion of the study, or until an MTD is identified, whichever comes first. A maximum of 25 subjects will be enrolled at the RP2D to further evaluate efficacy.

"To witness the activity of Annamycin in the treatment of STS lung metastases, even this early in a Phase 1 trial, we believe is encouraging. Four of the five patients that have completed scans to date demonstrated a response to treatment, including three with extended and, in one case, continuing stable disease and one patient with a substantial (>30%) reduction in tumor size. These interim data bolster our optimism about the potential for Annamycin to address the limitations with the current standard-of-care treatment options for STS lung metastases. Ultimately, we believe Annamycin has the potential to bring a new and effective treatment option to patients with a significant unmet need. With these data now in hand, we are cautiously optimistic as we begin patient enrollment and dosing in the next cohort," commented Walter Klemp, Chairman and CEO of Moleculin.

Mr. Klemp added, "We are also encouraged by the pace of recruitment so far in this trial. To have completed 2 full cohorts in just the first 4 months of the study with only one site open is faster than we would have expected, especially for a rare disease like STS lung metastases. And, with more sites joining the study before the end of the year, we believe there is the potential for this pace of recruitment to continue or even accelerate."

"As with all of the patients treated so far in our acute myeloid leukemia trials, no patients in this STS trial have exhibited any signs of cardiotoxicity," Mr. Klemp concluded. "This is an important point because, even though anthracyclines are considered a cornerstone chemotherapy for many types of cancer, including STS lung metastases, all currently approved anthracyclines are significantly cardiotoxic. Annamycin was designed to overcome this problem and we believe it has the potential to become the first non-cardiotoxic anthracycline approved for use. This could not only reduce the risk of many current anthracycline treatment regimens, but it could also enable longer treatment periods without cardiac risk."

The summary of interim data from the first two cohorts of the study are as follows:

First Cohort:

One subject is ongoing and is currently in cycle 5 of treatment and expects to enter cycle 6 of treatment at the end of this month. The end of cycle 4 scan revealed stable disease.
One subject discontinued after 6 cycles (4.5 months) due to progressive disease. However, stable disease was maintained up to that point.
One subject discontinued after cycle 1. The end of study scan was performed, and stable disease was observed. The subject was discontinued from the study because cycle 2 treatment was delayed greater than 6 weeks from the prior dosing.
Second Cohort:

One subject is ongoing and is currently in cycle 3 of treatment. The end of cycle 2 scan revealed partial response (PR, >30% reduction in tumor size).
One subject was discontinued from the study after 2 cycles after the end of cycle scan revealed progressive disease.
One subject received one cycle of treatment to-date and discontinued treatment for reasons unrelated to Annamycin. The end of study scans are scheduled in the coming weeks.
These are interim data and should be considered preliminary and subject to change.

The Company has now opened enrollment in the third cohort of the Phase 1b portion of the study. Three subjects minimum (6 maximum) for each dosing cohort will be enrolled until a maximum tolerated dose is identified. Therefore, up to 36 subjects may be enrolled in the Phase 1b portion of the study.

Annamycin currently has Fast Track Status and Orphan Drug Designation from the U.S. Food and Drug Administration for the treatment of STS lung metastases, in addition to Orphan Drug Designation for the treatment of relapsed or refractory acute myeloid leukemia. For more information about the Phase 1b/2 study evaluating Annamycin for the treatment of STS lung metastases, please visit clinicaltrials.gov and reference identifier NCT04887298.

Study Design

In Phase 1b, Annamycin is administered as an intravenous (IV) infusion over 2 hours on Day 1, followed by 20 days off (1 cycle = 21 days). Subjects visit the study site every 21 days (±3 days) at which time safety monitoring, including adverse events (AEs), a physical examination, laboratory evaluations (clinical chemistry, complete blood count), vital signs, weight measurements, Eastern Cooperative Oncology Group (ECOG) performance status, and electrocardiograms (ECGs) will be performed, followed by an IV infusion of study drug. Additional laboratory evaluations (clinical chemistry, complete blood count) will be performed at 7 days (± 3 days) and 14 days (± 3 days) from the Annamycin infusion for additional safety monitoring during each cycle. Cardiac function will be followed by echocardiogram (ECHO) scans at screening, at the end of the first two cycles and then every other cycle thereafter, at the end of treatment visit, and if feasible, during follow up at 6 months (±1 month) and 1 year (±1 month) after study drug discontinuation. As long as the Investigator considers that the benefits of treatment with Annamycin continue to outweigh the risks, treatment will continue every 21 days until tumor progression is observed or unacceptable toxicity occurs.

Tumor response is monitored every 6 weeks (±1 week) from Cycle 1 Day 1 during treatment, at the End of Treatment visit, and then every 3 months (±1 month) until disease progression using RECIST criteria. Those subjects who leave the study after a maximum response is achieved and who do not start another therapy will be followed every 3 months (±1 month) for progression-free survival (PFS). If a subject receives further therapy after discontinuing from the study, they will only be followed for overall survival (OS) and if feasible, follow-up ECHO scans at 6 months (±1 month) and 1 year (±1 month) after study drug discontinuation.

About Annamycin

Annamycin is the Company’s next-generation anthracycline that has been shown in animal models to accumulate in the lungs at up to 30-fold the level of doxorubicin. Importantly, Annamycin has also demonstrated a lack of cardiotoxicity in recently conducted human clinical trials for the treatment of acute myeloid leukemia (AML), and the Company believes that the use of Annamycin may not face the same usage limitations imposed on doxorubicin. Annamycin is currently in development for the treatment of AML and STS lung metastases.

Geron Announces Completion of Patient Enrollment in IMerge Phase 3 Clinical Trial in Lower Risk Myelodysplastic Syndromes

On October 18, 2021 Geron Corporation (Nasdaq: GERN), a late-stage biopharmaceutical company focused on the development and commercialization of treatments for hematologic malignancies, reported the completion of patient enrollment in the IMerge Phase 3 clinical trial to evaluate imetelstat, a first-in-class telomerase inhibitor, in lower risk myelodysplastic syndromes (MDS) (Press release, Geron, OCT 18, 2021, View Source [SID1234591453]). Based upon current planning assumptions, Geron expects top-line results for IMerge Phase 3 to be available at the beginning of January 2023.

"Completing patient enrollment in IMerge Phase 3 brings us one step closer to delivering imetelstat as a potential treatment alternative for patients with lower risk MDS who are relapsed or refractory to ESAs. Achieving durable transfusion independence remains a significant medical need for these patients," said Aleksandra Rizo, M.D., Ph.D., Geron’s Chief Medical Officer. "I would like to thank all of the patients and their families, the investigators, clinical site staff, as well as our employees for supporting the achievement of this important milestone."

Patients from the IMerge Phase 2 clinical trial achieved durable transfusion independence with imetelstat treatment, including transfusion-free periods greater than one year, irrespective of the disease subgroup, such as ringed sideroblast positive or ringed sideroblast negative. Such durability provides significant and meaningful clinical benefit to lower risk MDS patients given their chronic anemia and the debilitating impact of serial blood transfusions. In addition, depletion of cytogenetic abnormalities and reductions in key driver mutations associated with lower risk MDS were observed, and these results were also correlated with transfusion independence. Based on the IMerge Phase 2 data, taken together, the durability, molecular and cytogenetic data provide strong evidence for disease-modifying activity of imetelstat, which has the potential to differentiate it from other currently approved and investigational treatments in lower risk MDS today.

About IMerge Phase 3

IMerge Phase 3 is a double-blind, randomized, placebo-controlled Phase 3 clinical trial with registrational intent. The trial is designed to enroll approximately 170 transfusion dependent patients with Low or Intermediate-1 risk myelodysplastic syndromes (MDS), also referred to as lower risk MDS, who have relapsed after or are refractory to prior treatment with an erythropoiesis stimulating agent (ESA). The primary endpoint is the rate of red blood cell (RBC) transfusion independence (TI) for any consecutive period of eight weeks or longer, or 8-week RBC-TI rate. Key secondary endpoints include the rate of RBC-TI lasting at least 24 weeks, or 24-week RBC-TI rate, and the rate of hematologic improvement-erythroid (HI-E), defined as a reduction of at least four units of RBC transfusions over eight weeks compared with the prior RBC transfusion burden.

About Myelodysplastic Syndromes

Myelodysplastic syndromes are a group of diverse blood disorders that develop because bone marrow cells do not mature into healthy blood cells. There are approximately 60,000 people living with the disease in the United States. Approximately 70% of MDS patients are categorized in the lower risk groups at diagnosis, according to the International Prognostic Scoring System that assigns relative risk of progression to acute myelogenous leukemia and overall survival by taking into account the presence of a number of disease factors, such as cytopenias and cytogenetics. The predominant clinical problem in lower risk MDS is chronic anemia, and many patients become dependent on red blood cell transfusions which leads to iron overload, heart and kidney complications, decreases in quality of life and shorter overall survival.

About Imetelstat

Imetelstat is a novel, first-in-class telomerase inhibitor exclusively owned by Geron and being developed in myeloid hematologic malignancies. Data from Phase 2 clinical trials provide strong evidence that imetelstat targets telomerase to inhibit the uncontrolled proliferation of malignant stem and progenitor cells in myeloid hematologic malignancies resulting in malignant cell apoptosis and potential disease-modifying activity. Imetelstat has been granted Fast Track designation by the United States Food and Drug Administration for both the treatment of patients with non-del(5q) lower risk MDS who are refractory or resistant to an erythropoiesis-stimulating agent and for patients with Intermediate-2 or High-risk myelofibrosis whose disease has relapsed after or is refractory to janus associated kinase (JAK) inhibitor treatment.
