The topline data released today is from a period of one year of vaccination of all patients and represents an interim dataset after half of the treatment period.

A total of 20 subjects (median age 59, range 24 to 73) with AML (risk groups good, intermediate, poor: 13, 5, 2), in morphologic complete remission (CR) or complete remission with incomplete hematologic recovery (CRi) after induction or consolidation therapy, not eligible for allogeneic hematopoietic stem cell transplantation, were enrolled into this safety and feasibility Phase I/II trial, vaccinated and followed up for 12 months. Subjects in this trial had AML that was positive for Wilms Tumor-1 (WT-1) antigen with or without positivity for Preferentially Expressed Antigen in Melanoma (PRAME). Vaccination with dendritic cells, presenting the antigens WT-1 and PRAME, was carried out monthly, with a higher frequency within the first 6 weeks. AML diagnoses had been established with a median of 9.8 months before the first vaccination (range 4.5 to 17.5 months), and the last chemotherapy infusion had been performed at a median of 6.9 months (range 2 to 14.8 months).

The vaccinations were well tolerated with no serious adverse events (SAEs) related to the treatment. The most common adverse events (AEs) were injection site related, accounting for 35% of all AEs and mild in nature (Grade 1). The feasibility of the manufacture of the dendritic cell vaccine in these chemotherapy-pretreated subjects was already presented earlier this year (abstract AACR (Free AACR Whitepaper)).

After a 12-months treatment period, the overall survival was 89% (18 of 20 patients, 95% confidence interval: 61 to 97%) and the progression free survival was 60% (12 of 20 patients, 95% confidence interval: 36 to 78%). Most relapses, 5 out of 8, occurred within the first 80 days after the start of the vaccination, out of which the 2 deaths were in patients with relapses on days 45 and 64, which could point to a starting relapse upon entering the study.

The completion of the ongoing trial is scheduled for the end of 2019 following a two-year treatment period.

Dr. Yngvar Floisand, Head Physician of the Department of Hematology at the Oslo University Hospital and Principal Investigator of the trial, comments: "The interim results after one year of treatment demonstrate an excellent safety profile and a very good manufacturability of Medigene’s personalized DC vaccines. The initial data on the efficacy of the therapy point in the right direction, but we have to complete the two-year trial period for a conclusive evaluation."

Dr. Kai Pinkernell, CMO and CDO of Medigene AG, comments: "We are pleased about these first encouraging interim results from our ongoing safety and feasibility trial with our DC vaccine. AML is a serious disease with poor long-term prognosis and we are committed to developing new treatment options for those patients in urgent need."

Medigene intends to present the detailed data from the interim analysis at a scientific conference in the near future.

About acute myeloid leukaemia (AML): Acute myeloid leukaemia is a malignant disease of the hematopoietic system, affecting mainly adults above 60 years of age. In Germany, about 3,600 cases are registered annually.

AML is caused by uncontrolled growth of dysfunctional hematopoietic precursor cells in the bone marrow. These cells prevent the generation of normal blood cells, causing a decrease in erythrocytes and platelets, for example. Typical symptoms of AML include anemia, fever, increased risk of infection, and bleeding. AML progresses rapidly and may be fatal within a few weeks or months, if untreated.

AML treatment is often started with intensive chemotherapy, followed by consolidation with or without allogeneic hematopoietic stem cell transplantation. Unfortunately, a significant proportion of patients suffer a relapse of the original disease. Depending on the biologic risk profile of the disease, age and co-morbidity the long-term survival is highly variable.

About Medigene’s DC vaccines: In addition to Medigene’s development focus on T cell-receptor modified T cells (TCR-Ts), the Company has developed a new generation of antigen-tailored dendritic cell (DC) vaccines.

Dendritic cells (DC) can take up antigens, process them and present peptides on their surface in a form that can induce antigen-specific T cells to mature and proliferate. In this way, T cells recognize and eliminate tumor cells which bear the same antigen peptide on their surface. Dendritic cells can also induce natural killer cells (NK cells) to attack tumor cells. The scientific team of Medigene has developed new, fast and efficient methods for generating autologous (patient-specific) mature dendritic cells which have the relevant characteristics to generate very strong T cell and NK cell immune responses. The dendritic cells can be loaded with various tumor antigens to treat different forms of cancer. Since an immune response builds up over the total time of administration of the DC vaccine, this form of therapy is particularly designed for patients who suffer from a tumor disease which has been reduced to such an extent by chemotherapy that the prevention of the recurrence of the tumor disease is the main goal

On December 19, 2018 An obscure sliver of RNA with a grim-sounding name is unexpectedly taking center stage as a linchpin in transforming pre-leukemic cells into full-blown leukemia (Press release, Apexian Pharmaceuticals, DEC 19, 2018, View Source [SID1234532135]). Apexian Pharmaceuticals’ reported that latest studies in collaboration with Indiana University’s Simon Cancer Center investigator Dr. Reuben Kapur show promise for halting that transformation.

These results, published December 6, 2018, in Cell Stem Cell, explain how a long noncoding RNA called Morrbid becomes hyperactivated after an acute inflammatory insult. Morrbid’s overzealous signaling functionally alters the bone marrow’s myeloid cells (precursors to white blood cells) when those cells are deficient in a tumor-suppressor gene called TET2. The cells mature rapidly, increase in absolute numbers, become resistant to programmed cell death, and churn out high levels of inflammatory proteins in a sustained, self-perpetuating response.

Inflammation has long been suspected of contributing to cancer, but these results establish a causative link. Dr. Kapur’s and Apexian’s results also support others’ findings that Morrbid controls myeloid cell lifespan.

Using a mouse model that mimics human acute myeloid leukemia, Dr. Kapur and Apexian’s Chief Science Officer, Mark Kelley, PhD demonstrated that Apexian’s flagship compound APX3330 could reduce Morrbid’s activity. Blocking both the precancerous cells’ growth and the cells’ production of inflammatory proteins.

Such anti-inflammatory therapy could be of clinical value in people carrying TET2 mutations.

"Our ongoing pre-clinical research continues to identify the role that APX3330 plays in impacting disease including hematological disorders, said Dr. Mark Kelley, Chief Scientific Officer. "Inflammation plays a critical role in the growth and survival of blood stem cells with pre-leukemia mutations such as TET2 and increases the risk of blood related cancers. APX3330 blocked this change from pre-leukemia to leukemia in the mouse models

"The CTA approval for the first clinical trial of INKmune is a major milestone for the company," said RJ Tesi, M.D, chief executive officer and co-founder of INmune Bio. "INKmune is our second cancer program to enter the clinic and will be tested in women with relapsed and refractory ovarian cancer, which accounts for more deaths than any other cancer of the female reproductive system."

Modern cancer therapy strives to harness the patient’s immune system to help control the cancer. Natural killer (NK) cells of the innate immune system must function normally to eliminate residual disease – the cancer left over after traditional cancer therapy that is the cause of cancer relapse. INKmune is a novel cancer therapy that may switch on the patient’s NK cells to attack residual disease that can be the cause of treatment failure.

"This approval represents external validation of our pre-clinical data set using Tumor Primed NK cells against a range of cancer cells which are insensitive to NK killing," says Dr. Mark Lowdell, chief scientific officer and co-founder of INmune Bio. "The way that INKmune activates the patient’s own immune system means that it could be used for many types of cancer; women with ovarian cancer are just the first of many patients we hope to treat with INKmune."

Today, ovarian cancer ranks fifth in cancer deaths among women. In 2018 alone, the American Cancer Society estimated 22,240 new cases in the US. Unfortunately, when ovarian cancer relapse occurs, the average survival is between 12 to 18 months, and fewer than 1 in 10 patients survive beyond five years following standard chemotherapy treatment.
