Among the findings presented at ASH (Free ASH Whitepaper) were the identification of CXCR4/CXCR2 expression ratio and bone marrow homing of myeloid cells as potential biomarkers of tipifarnib activity across the bone marrow cancers, myelodysplastic syndromes (MDS), acute myeloid leukemia (AML) and chronic myelomonocytic leukemia (CMML), further showing that the CXCL12/CXCR4 pathway is a potential therapeutic target of farnesyl transferase inhibitors.

"Although tipifarnib has previously demonstrated clinical responses in certain patients with AML and MDS, no molecular mechanism of action was identified that could explain the activity of the drug candidate in those patient populations," said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. "These new findings are exciting because they may define potential biomarkers for tipifarnib in bone marrow tumors and characterize a subgroup of patients that are most likely to derive clinical benefit from a targeted therapy such as tipifarnib."

Previously, Kura Oncology reported preliminary results from an ongoing Phase 2 clinical trial of tipifarnib in patients with peripheral T-cell lymphoma (PTCL) identifying the CXCL12/CXCR4 pathway as a potential target of tipifarnib. Specifically, high levels of CXCL12 gene expression and absence of single nucleotide gene variations in the 3′-untranslated region of the CXCL12 gene were associated with observed clinical activity of tipifarnib in these PTCL patients.

In the ASH (Free ASH Whitepaper) presentation entitled, "The CXCL12/CXCR4 Pathway As a Potential Target of Tipifarnib: Preliminary Results from an Open-Label, Phase II Study in Relapsed or Refractory Peripheral T-Cell Lymphoma," Kura Oncology extends these observations and provides data supporting the observed tipifarnib-derived clinical benefit for the CXCL12-positive population.

CXCL12 is a chemokine that is secreted in large amounts by lymph nodes, bone marrow stroma, liver, and lung, and plays key roles in tumor invasion, bone marrow homing and site of metastasis. Among its multiple functions, CXCL12 is essential for homing of myeloid cells to the bone marrow and lymphoid cells to lymph nodes and other organs.

Based on its initial observations in PTCL, the company investigated a role for the CXCL12/CXCR4 pathway and bone marrow homing of myeloid cells as biomarkers of tipifarnib activity in AML and MDS studies.

In the ASH (Free ASH Whitepaper) presentation entitled, "The CXCL12/CXCR4 Pathway As a Potential Target of Tipifarnib in Acute Myeloid Leukemia and Myelodysplastic Syndromes," Kura Oncology presented results that identify the ratio of CXCR4/CXCR2 gene expression and bone marrow homing of myeloid cells as potential biomarkers of the activity of tipifarnib in certain bone marrow tumors. The results were obtained by analyzing data from previous studies of tipifarnib in AML and MDS, as well as data from the ongoing Phase 2 clinical trial of tipifarnib in CMML.

"We were very encouraged to identify CXCR4/CXCR2 expression ratio and bone marrow homing as markers of tipifarnib’s activity in MDS, AML and CMML," said Antonio Gualberto, M.D., Ph.D., Chief Medical Officer at Kura Oncology. "Although our analysis is retrospective, the fact that we observe a consistent clinical benefit across different endpoints, treatment settings and indications gives us increased confidence in the potential for these biomarkers. Based on our preliminary data, we believe CXCL12/CXCR4 may have the potential to unlock the therapeutic value of farnesyl transferase inhibition across multiple bone marrow neoplasias."

About Tipifarnib

Kura Oncology’s lead candidate, tipifarnib, is a potent and selective inhibitor of the enzyme farnesyl transferase, a key cell signaling process implicated in cancer initiation and development. Tipifarnib has previously been studied in more than 5,000 patients in more than 70 clinical trials has a well-established safety profile and has demonstrated compelling and durable anti-cancer activity in certain patient subsets.

Leveraging advances in next-generation sequencing as well as emerging information about cancer genetics and tumor biology, Kura Oncology is seeking to identify patients most likely to benefit from tipifarnib. The company is conducting clinical and preclinical studies in multiple disease indications where tipifarnib has previously shown signs of activity with the goal of identifying and validating biomarkers associated with the observed clinical activity of tipifarnib.

In September 2017, Kura Oncology reported that its Phase 2 trial of tipifarnib in patients with HRAS mutant head and neck squamous cell carcinomas (HNSCC) achieved its primary efficacy endpoint prior to the completion of patient enrollment. The company is now planning to initiate a registration-enabling study of tipifarnib in HRAS mutant HNSCC in 2018.

Phase 1 Data for Flotetuzumab, MacroGenics’ CD123 x CD3 DART® Molecule, Presented at 59th Annual ASH Meeting

On December 11, 2017 MacroGenics, Inc. (NASDAQ:MGNX), a clinical-stage biopharmaceutical company focused on discovering and developing innovative monoclonal antibody-based therapeutics for the treatment of cancer, as well as autoimmune disorders and infectious diseases, reported the presentation of clinical data from its ongoing Phase 1 study of flotetuzumab in an oral session at the 59th Annual Meeting of the American Society of Hematology (ASH) (Free ASH Whitepaper) in Atlanta, Georgia (Press release, MacroGenics, DEC 11, 2017, View Source [SID1234522556]). John E. Godwin, M.D., Program Leader, Hematologic Malignancies at Earle A. Chiles Research Institute at Providence Cancer Center in Portland, Oregon presented "Preliminary Results of a Phase 1 Study of Flotetuzumab, a CD123 x CD3 Bispecific DART Protein, in Patients with Relapsed/Refractory Acute Myeloid Leukemia and Myelodysplastic Syndrome."

The ongoing Phase 1, first-in-human study of flotetuzumab was designed to determine safety, tolerability, maximum tolerated dose and initial anti-leukemic activity in patients with relapsed or refractory acute myeloid leukemia (AML) or intermediate-2/high risk myelodysplastic syndrome (MDS). To date, a total of 57 patients have been enrolled, including 11 AML patients in the dose expansion cohort.

Consistent with the dose escalation data that was previously presented at ESMO (Free ESMO Whitepaper) Congress 2017 in September, flotetuzumab has continued to demonstrate acceptable tolerability in patients treated to date in the dose expansion cohort. Infusion-related reaction and cytokine release syndrome (CRS) were the most common adverse events observed, with Grade 3 CRS occurring in 9 of 57 patients (15.8%). Implementation of a two-step, lead-in dose as well as early intervention with anti-cytokine therapy has helped to limit the severity and incidence of CRS.

As of the data cut-off date, of the eight evaluable patients in the dose expansion cohort who received a lead-in dose followed by 500 ng/kg/day of flotetuzumab via continuous IV infusion, six patients (75%) have evidence of anti-leukemic activity, with three of these patients experiencing an objective response. This included two patients who experienced CR/CRi and one patient who achieved MLF (morphologic leukemia-free state).

The duration of response for the eight patients who have achieved a MLF, CRi or CR in the dose escalation and dose expansion cohorts ranged from 1.0 to 5.8 months, with five of these responses still ongoing as of the November 30, 2017 data cut-off.

Further, in a translational data poster presentation, MacroGenics also described studies that support a rationale for using checkpoint blockade as an approach to potentially enhance the anti-leukemic activity of flotetuzumab. Among these findings, modulation of the PD-1/PD-L1 pathway was observed in patients treated with flotetuzumab, and the combination of flotetuzumab and PD-1/PD-L1 inhibitors was shown to synergistically enhance T-cell mediated cytotoxicity against AML cell lines in vitro.

"We continue to be encouraged by the tolerability and anti-leukemic activity of flotetuzumab as well as by the early data regarding the durability of responses observed in patients from our ongoing Phase 1 study of flotetuzumab," said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. "In addition, given the data-supported rationale for combining flotetuzumab with anti-PD-1, we intend to initiate a combination study with the anti-PD-1 mAb, MGA012, in the coming months, while we continue to enroll the AML and MDS dose expansion cohorts. We look forward to sharing additional flotetuzumab clinical data in 2018."

About Flotetuzumab

Flotetuzumab (also known as MGD006 and S80880) is a clinical-stage molecule that recognizes both CD123 and CD3. CD123, the Interleukin-3 receptor alpha chain, has been reported to be over-expressed on cancer cells in a wide range of hematological malignancies, including AML and MDS. The primary mechanism of action of flotetuzumab is believed to be its ability to redirect T lymphocytes to kill CD123-expressing cells. To achieve this, the DART molecule combines a portion of an antibody recognizing CD3, an activating molecule expressed by T cells, with an arm that recognizes CD123 on the target cancer cells.

Flotetuzumab is currently being evaluated at 13 clinical sites in the U.S. and Europe in a Phase 1 study designed to assess the safety, tolerability, maximum tolerated dose and initial anti-leukemic activity of the molecule in patients with relapsed/refractory AML or intermediate-2/high risk MDS. MacroGenics retains full development and commercialization rights to flotetuzumab in the U.S., Canada, Mexico, Japan, South Korea and India. Servier participates in the development of flotetuzumab and has exclusive rights to this molecule in all other countries. The U.S. Food and Drug Administration has granted orphan drug designation to flotetuzumab for the treatment of AML.

Spark Therapeutics and Pfizer Announce Longer-term Preliminary Data Showing Consistent and Sustained Factor IX Levels in Hemophilia B at 59th American Society of Hematology (ASH) Annual Meeting and Exposition

On December 11, 2017 Spark Therapeutics (NASDAQ:ONCE), a fully integrated gene therapy company dedicated to challenging the inevitability of genetic disease, and Pfizer Inc. (NYSE:PFE), reported that, with a cumulative follow-up of more than 13 patient years of observation, all 11 participants in the ongoing Phase 1/2 clinical trial of investigational SPK-9001 for the treatment of patients with hemophilia B had discontinued routine infusions of factor IX concentrates and shown sustained steady-state factor IX activity levels with no serious adverse events, thrombotic events or factor IX inhibitors observed (Press release, Pfizer, DEC 11, 2017, View Source [SID1234522561]). Based on individual participant history for the year prior to the study, the overall annualized bleeding rate (ABR) was reduced by 97 percent (calculated based on data after week four; 95 percent based on data after infusion) to a mean of 0.3 (0.5) annual bleeds, compared to a mean of 10.5 bleeds annually before SPK-9001 administration. Overall annualized infusion rate (AIR) was reduced 99 percent (calculated based on data after week four; 97 percent based on data after infusion) to a mean of 0.8 (1.7) annual infusions, compared to a mean of 62.5 infusions per year before SPK-9001 administration. Data on all 11 participants were presented today by Lindsey A. George, M.D., attending physician in the Division of Hematology at Children’s Hospital of Philadelphia and principal investigator of the trial, at the 59th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition in Atlanta.

"We believe these longer-term data are meeting critical goals of our hemophilia programs," said Katherine A. High, M.D., president and head of research and development at Spark Therapeutics. "Now, with four participants followed for more than 18 months, we continue to see consistent levels of factor IX activity, no serious adverse events, as well as a sustained reduction in both the symptoms of hemophilia and the prophylactic and disease management protocols that were used prior to infusion with SPK-9001."

As of the Nov. 29, 2017 data cutoff, the mean steady-state factor IX activity level at 12 weeks post-administration for the 11 participants was 36 percent of normal (range as of the data cutoff: 15 to 78 percent). As of the data cutoff, the last participant to be infused, who received SPK-9001 manufactured using an enhanced process, was out eight months following SPK-9001 infusion, with a mean factor IX activity level of 60 percent. Spark Therapeutics will enroll up to four additional participants in the current Phase 1/2 clinical trial who will receive SPK-9001 manufactured using an enhanced process to test its comparability to the SPK-9001 received by the first 10 participants enrolled in the ongoing trial.

In this open-label, non-randomized and multicenter Phase 1/2 clinical trial, there were no serious adverse events during or following infusion with SPK-9001, and no participants experienced thrombotic events or developed factor IX inhibitors. Two participants developed an asymptomatic and transient increase in liver enzymes that resolved with a tapering dose of oral corticosteroids. One participant with severe joint disease administered factor for suspected joint bleeding, while a second participant recorded one spontaneous bleed.

About Hemophilia B
Hemophilia, a rare genetic bleeding disorder that causes the blood to take a long time to clot because of a deficiency in one of several blood clotting factors, is almost exclusively found in males. People with hemophilia are at risk for excessive and recurrent bleeding from modest injuries, which have the potential to be life threatening. People with severe hemophilia often bleed spontaneously into their muscles or joints, or rarely into other critical closed spaces such as the intracranial space, where bleeding can be fatal. The incidence of hemophilia B is one in 25,000 male births. People with hemophilia B have a deficiency in clotting factor IX, a specific protein in the blood. Hemophilia B also is called congenital factor IX deficiency or Christmas disease. The current standard of care requires recurrent intravenous infusions of either plasma-derived or recombinant factor IX to control and prevent bleeding episodes. There exists a significant need for novel therapeutics to treat people living with hemophilia.

About the SPK-FIX Program and SPK-9001
SPK-9001 is a novel investigational vector that contains a bio-engineered adeno-associated virus (AAV) capsid and a codon-optimized, high-activity human factor IX gene enabling endogenous production of factor IX.

Spark Therapeutics and Pfizer entered into a collaboration in December 2014 for the SPK-FIX program, including SPK-9001, under which Spark Therapeutics is responsible for conducting all Phase 1/2 studies for any product candidates, while Pfizer will assume responsibility for pivotal studies, any regulatory activities and potential global commercialization of any products that may result from the collaboration.
