Summary of Recent Highlights by Modality

Prophylactic vaccines:

Moderna is developing vaccines against viral diseases where there is unmet medical need – including complex vaccines with multiple antigens for common diseases, as well as vaccines against epidemic and pandemic threats to global public health.

hMPV+PIV3 (mRNA-1653): In February, Moderna announced positive data from a planned interim analysis of safety and immunogenicity from its Phase 1 study of mRNA-1653 in healthy adults. mRNA-1653 is designed to protect against human Metapneumovirus (hMPV) and Parainfluenza Virus Type 3 (PIV3), two viruses that cause respiratory illnesses. It is a combination vaccine that consists of two distinct mRNA sequences encoding the fusion (F) proteins of hMPV and PIV3 formulated in Moderna’s proprietary lipid nanoparticle (LNP) technology. Moderna plans to advance mRNA-1653 into a Phase 1b study of pediatric subjects.
Zika Vaccine (mRNA-1893): Moderna’s follow-on Zika vaccine candidate, mRNA-1893, continues to progress toward an IND filing. There will be no further development of Moderna’s first Zika candidate, mRNA-1325. The Biomedical Advanced Research and Development Authority (BARDA) remains committed to its grant of up to approximately $125 million for development of a Zika vaccine.*
Publication of Note: In February, Moderna researchers published new data in the scientific journal Molecular Therapy: Nucleic Acids that demonstrate how mRNA vaccines delivered with a proprietary Moderna lipid nanoparticle (LNP) show enhanced tolerability and comparable immunogenicity relative to legacy LNPs.
Cancer Vaccines: These programs focus on stimulating a patient’s immune system with antigens derived from tumor-specific mutations to enable the immune system to elicit a more effective antitumor response.

Personalized Cancer Vaccine (PCV) (mRNA-4157): In February, Moderna and Merck submitted a new protocol to the FDA to commence a randomized Phase 2 study to assess whether post-operative adjuvant therapy with mRNA-4157, in combination with Merck’s PD-1 inhibitor KEYTRUDA, improves recurrence-free survival compared to KEYTRUDA alone. The study has a primary endpoint of recurrence-free survival with a primary analysis at 12 months and will be conducted with patients that have had complete resection of cutaneous melanoma but remain at high risk of recurrence.

Moderna’s PCV is designed and manufactured individually based on the DNA sequence of a patient’s tumor, encoding for peptides containing mutations found in their cancer in order to deliver multiple unique and personalized neoantigens in a single vaccine. Moderna’s PCV now includes up to 34 neoantigens, up from 20. Moderna has also fully operationalized its personalized vaccine unit at its manufacturing site in Norwood, Mass., which is expected to further enhance supply chain management and enable the Company to accelerate manufacturing of individualized cancer treatments for patients.
Intratumoral Immuno-oncology: These programs aim to drive anti-cancer T cell responses by injecting mRNA therapies directly into tumors.

OX40L + IL23 + IL36γ (Triplet) (mRNA-2752): mRNA-2752 has cleared dosing of the first cohort of patients in the Phase 1 study and the dosing of a second cohort has commenced. mRNA-2752, also known as the Triplet, is an intratumoral injection comprising three mRNAs encoding for OX40L + IL23 + IL36γ for the treatment of advanced or metastatic solid tumor malignancies or lymphoma. The open-label, multi-center study is evaluating the safety and tolerability of mRNA-2752 as a single agent and in combination either with AstraZeneca’s durvalumab or tremelimumab, and will assess anti-tumor activity, protein expression in tumors and pharmacokinetics.
IL12 (MEDI1191): An IND has been opened for a Phase 1 study of mRNA encoding IL12 injected intratumorally in advanced or metastatic solid tumors. Moderna’s strategic collaborator AstraZeneca will lead this open-label, multi-center study of intratumoral injections of MEDI1191 alone and in combination with a checkpoint inhibitor. Moderna provided the preclinical data package to support the IND submission and will provide clinical supply for this trial. MEDI1191 is an mRNA encoding for IL12, a potent immunomodulatory cytokine, which aims to enhance immune response in immunologically "cold" tumors.
Publication of Note: In January, Moderna announced the publication of pre-clinical data in the scientific journal Science Translational Medicine that showed local delivery of the Triplet (mRNA-2752) induced a broad immune response and caused tumor regression in both injected lesions and distant un-injected tumors in mice. When combined with checkpoint inhibitors, mRNA-2752 was able to induce responses in tumor models that are otherwise unresponsive to checkpoint inhibitors.
Localized Regenerative Therapeutics: These programs focus on the potential for the localized production of proteins to be used as a regenerative medicine for damaged tissues.

Publication of Note: In February, Moderna announced the publication of data from a Phase 1a/b study in Nature Communications showing the potential of mRNA encoding for vascular endothelial growth factor A (VEGF-A) as a regenerative therapeutic. When injected directly into the skin of patients with diabetes mellitus, the mRNA encoding VEGF-A was well tolerated, showed protein expression as demonstrated by dose-dependent protein translation and demonstrated protein pharmacology with evidence of increased blood flow. The data supported advancement of AZD8601, which now is in an ongoing Phase 2a study led by AstraZeneca.
Systemic Secreted Therapeutics: In this modality, mRNA is delivered systemically to create proteins that are secreted outside the cell with the aim of producing pharmaceutically active proteins with therapeutic effects across the human body.

Antibody Against the Chikungunya Virus (mRNA-1944): Dosing of the first cohort has been completed in Moderna’s Phase 1 study evaluating the safety and tolerability of escalating doses of mRNA-1944 via intravenous infusion in healthy adults. This is the first monoclonal antibody encoded by mRNA to be dosed in a human and the first development candidate from the Company’s systemic therapeutics modalities to start clinical testing. Moderna announced the dosing of the first patient in the study in February. mRNA-1944 encodes a fully human IgG antibody originally isolated from B cells of a patient with a prior history of potent immunity against chikungunya infection and is composed of two mRNAs that encode the heavy and light chains of this anti-chikungunya antibody within Moderna’s proprietary lipid nanoparticle (LNP) technology. This formulation was developed by Moderna and is utilized for IV delivery of each of its systemic therapeutics, including its rare disease programs.
Systemic Intracellular Therapeutics: These programs aim to deliver mRNA into cells within target organs as a therapeutic approach for diseases caused by a missing or defective protein.

Methylmalonic Acidemia (MMA) (mRNA-3704): The FDA has granted Fast Track designation for mRNA-3704, the first for a Moderna investigational medicine. Moderna now has an open IND and is preparing to begin a Phase 1/2 open-label, multi-center, multiple ascending dose study of mRNA-3704 in pediatric patients with isolated MMA due to MUT enzyme deficiency. The objectives of the study are to evaluate safety and tolerability, assess the pharmacodynamic response and characterize the pharmacokinetic profile of mRNA-3704. The program previously received Rare Pediatric Disease Designation by the FDA and Orphan Drug Designation by both the FDA and the European Medicines Agency (EMA). This is Moderna’s first rare disease program to advance into clinical trials.

Bio-Path Announces Clinical Update to Interim Analysis of Phase 2 Prexigebersen Trial in Acute Myeloid Leukemia

On March 6, 2019 Bio-Path Holdings, Inc., (NASDAQ: BPTH), a biotechnology company leveraging its proprietary DNAbilize antisense RNAi nanoparticle technology to develop a portfolio of targeted nucleic acid cancer drugs, reported a clinical update to the previously reported interim analysis from the Phase 2 trial of prexigebersen (BP1001) for the treatment of acute myeloid leukemia (AML) and provides its plans for the compound’s clinical development moving forward toward registration (Press release, Bio-Path Holdings, MAR 6, 2019, View Source [SID1234534065]).

The open-label Phase 2 study in Stage 1 evaluated the efficacy and safety of prexigebersen in conjunction with low dose cytarabine (LDAC), a therapeutic regimen well-established in treatment of AML patients who cannot or elect not to be treated with more intensive chemotherapy. The primary objective of the study is to determine whether the combination of prexigebersen and LDAC provides greater efficacy than would be expected with LDAC alone in a de novo patient population. Subsequently, Stage 2 of the study added a second cohort that is evaluating the efficacy and safety of prexigebersen in conjunction with Decitabine in addition to the cohort evaluating prexigebersen in conjunction with LDAC.

In April 2018, Bio-Path completed an initial interim analysis of 17 evaluable patients from Stage 1 of the Phase 2 study. These results showed a promising safety and efficacy profile with 47% of patients having a response comprised of four complete response (CR) patients, including one CRi (complete response with incomplete hematologic recovery) and four patients with stable disease. Recently, the data from the 17 evaluable patients was updated, and following a meeting with the principal investigators of the study, those results now show that the efficacy profile has improved to where 11 (65%) of the 17 evaluable patients had a response, including five (29%) who achieved CR (including one CRi) and one morphologic leukemia free state (MLFS), and six stable disease responses, including two patients who had greater than a 50% reduction in bone marrow blasts. Importantly, through investigation by the principal investigators, it was observed that 68% of these patients were secondary AML patients, an extremely difficult class to treat.

The efficacy data from the 17 evaluable patients was very favorable in this challenging population compared to the reported CR (complete response), CRp (complete response with incomplete platelet recovery), and CRi rates with LDAC treatment alone of 7-13%1 in this patient population. Additionally, a study of newly approved Venetoclax plus LDAC in these newly diagnosed patients reported a 42% CR/CRh (complete response with incomplete hematologic response) response rate; however, this study had only 46% secondary AML compared to 68% in the Bio-Path 17-patient interim analysis.

"These updated interim data from Stage 1 of our Phase 2 study of prexigebersen in de novo AML patients give strong evidence of the safety and efficacy profile of our lead compound and underscore its potential to provide meaningful treatment improvement in this difficult-to-treat patient population," said Peter Nielsen, President and Chief Executive Officer of Bio-Path. "We were particularly pleased with these results, especially when you consider that the large percentage of these patients are secondary AML patients. The CR/CRp/CRi rate for LDAC treatment alone for the class of patients in this study was benchmarked at 7-13%1, whereas prexigebersen treatment with LDAC is currently showing a 29% CR/CRi/MLFS rate, with a highly favorable safety profile."

"Prexigebersen with its efficacy and safety profile, is an ideal combination candidate with frontline therapy. Our aim is to match prexigebersen with the leading frontline therapies to improve treatment options for patients. Consequently, we maintain an in-depth knowledge of all new therapies and therapies in development. As the treatment landscape evolves, we continue to nimbly respond to those advances and the plans for our registration-directed clinical development program for prexigebersen as a treatment for AML reflects these changes," concluded Mr. Nielsen.

The recent approval of the frontline therapy Venetoclax provides an opportunity for combining prexigebersen with the combination Venetoclax plus Decitabine for the treatment of de novo AML patients. Venetoclax is a drug whose activity is against the anti-apoptotic protein Bcl-2 based on neutralizing the protein’s BH3 domain. It is also an approved treatment in chronic lymphocytic leukemia (CLL) patients; however, with the exception of some patients treated with allogeneic hematopoietic cell transplantation (HCT), disease relapse invariably occurs, often times due to BH3 domain mutation over time. Bio-Path’s BP1002 is a drug candidate that targets the Bcl-2 protein, just as Venetoclax. However, BP1002 activity is based on blocking the Bcl-2 messenger RNA, and not the BH3 domain. As a result, Bio-Path believes that BP1002 could provide an alternative to Venetoclax CLL patients who have relapsed. Likewise, Bio-Path believes there will be AML patient relapses from Venetoclax treatments, representing an additional opportunity for Bio-Path to treat those patients with BP1002.

As a result, Bio-Path intends to file for registration of BP1002 for the treatment of Venetoclax relapses in both CLL patients and AML patients. The planned modification of the Company’s Phase 2 clinical program in AML to include Venetoclax combination treatment with prexigebersen will give Bio-Path early experience with treating Bcl-2 driven anti-apoptosis in these patients.

Registrational Clinical Development Program

After treating nearly 70 patients, Bio-Path believes it now has a plan with definable paths to registration. Results to date have shown prexigebersen, with its efficacy and safety profile, to be an ideal combination candidate with frontline therapy. The Principal Investigators of the Phase 2 study and Bio-Path’s Scientific Advisory Board helped prepare the revised clinical program for prexigebersen in AML. The new registration-directed plan is as follows:

·Amend the existing Stage 2 prexigebersen + Decitabine Phase 2 AML cohort in untreated de novo patients to add untreated high risk myelodysplastic syndrome (MDS) patients. High risk MDS patients are typically treated with Hypomethylating agents alone and the combination treatment may benefit these patients.
·Cancel the Stage 2 prexigebersen + LDAC Phase 2 AML cohort in untreated de novo patients. Although Bio-Path has had good success with prexigebersen + LDAC, there is a strong preference by oncologists for Decitabine over LDAC as the combination therapy drug partner in treating these patients.
·Amend the existing Phase 2 protocol to add a cohort of prexigebersen in combination with Decitabine in refractory/relapsed AML patients. This is based on the Company’s experience in this setting, including the Phase 1b safety segment combination treatment in refractory/relapsed patients. Refractory/relapsed high risk MDS patients will be included in this cohort.

·Preclinical efficacy studies are underway for prexigebersen + Decitabine + Venetoclax triple combination to confirm the incremental efficacy benefit of the triple combination.
·Amend the protocol of the Phase 2 trial to perform a small safety assessment of the triple combination prexigebersen + Decitabine + Venetoclax in the refractory/relapsed AML plus high risk MDS patient cohort.
·Following a successful safety assessment, initiate a registration-directed cohort of the trial by adding Venetoclax to the prexigebersen + Decitabine combination treatment of refractory/relapsed AML plus high risk MDS patients.
·Amend the protocol of the Phase 2 trial to initiate a Prexigebersen + Decitabine + Venetoclax registration-directed trial for untreated AML and high risk MDS patients, to determine if more durable responses and longer survival is observed compared to patients treated with the Decitabine + Venetoclax combination.

The result from these transformational steps will be two registration-directed cohorts of Bio-Path’s Phase 2 clinical trial in AML, both studying the triple combination prexigebersen + Decitabine + Venetoclax but in two separate patient populations, including untreated AML plus untreated high risk MDS patients, and refractory/relapsed AML plus refractory/relapsed high risk MDS patients. Bio-Path expects that many of the Venetoclax patients will relapse and that Bio-Path second drug candidate BP1002 targeted to Bcl-2 can replace Venetoclax enabling continued patient treatment with the triple combination. We expect this to result in a third registration-directed clinical program, specifically for BP1002 in Venetoclax treatment failures.
