The published dataset (as of 22 June 2018) includes 74 evaluable patients; all patients received Betalutin as a single administration and have six or more months of follow-up. The complete dataset will be presented at ASH (Free ASH Whitepaper).

The conclusions from the updated study results are that Betalutin is well-tolerated and has promising anti-tumour activity in recurrent iNHL, especially in follicular lymphoma (FL) patients. Key results are:

Patients Number of patients (n) Overall Response Rate (ORR) Complete Responses (CR)
All iNHL patients 74 61 % 26 %
FL patients 57 65 % 24 %
3L FL patients (≥2 prior therapies) 37 70 % 27 %
FL patients in Arm 1
(40 mg lilotomab followed by 15 MBq/kg Betalutin) 25 64 % 28 %
FL patients in Arm 4
(100 mg/m2 lilotomab followed by 20 MBq/kg Betalutin) 16 69 % 19 %
The median duration of response (mDoR), when treated with a single administration of Betalutin, was 13.3 months for all patients (20.5 months for those with a CR) based on a median follow-up of 9.1 months (range 4.9-49.5 months). Twenty-six patients (35%) have remained free of disease progression for more than 12 months.

Betalutin therapy was well tolerated with no unexpected safety findings and the safety profile is both predictable and manageable.

The data continue to highlight the encouraging clinical profile of single-agent Betalutin therapy in iNHL patients, particularly in those with FL, the primary NHL population for which Betalutin is being developed.

Two recommended Phase 2 doses were identified from this study and are now being compared in the pivotal, randomised Phase 2b PARADIGME trial in relapsed, anti-CD20 refractory FL patients who have received two or more prior therapies.

Arne Kolstad, lead investigator of LYMRIT 37-01 and senior consultant in medical oncology and radiotherapy, Oslo University Hospital Radiumhospitalet, said: "Patients with relapsed/refractory follicular lymphoma have a need for effective treatment options that improve their quality of life, especially elderly patients. The clinical profile that Betalutin is consistently showing in this patient population is very encouraging."

Lisa Rojkjaer, Chief Medical Officer of Nordic Nanovector, commented: "We are very pleased with the clinical data. The results from Arm 4 further support the decision to compare the 100 mg/m2 lilotomab + 20 MBq/kg Betalutin dosing regimen from Arm 4 with the 40 mg lilotomab + 15 MBq/kg regimen from Arm 1 in the pivotal phase 2b PARADIGME trial. The emerging data on the durability of the responses together with the safety profile of Betalutin and the convenience of a single administration underscore the potential of Betalutin for the treatment of patients with advanced-stage follicular lymphoma."

Sierra Oncology to Report Clinical Data at ASH 2018 from Translational Biology Study of Momelotinib in Transfusion Dependent Patients

On November 1, 2018 Sierra Oncology, Inc. (Nasdaq: SRRA), a clinical stage drug development company focused on advancing targeted therapeutics for the treatment of patients with significant unmet needs in hematology and oncology, reported that clinical data from a translational biology study of momelotinib in 41 transfusion dependent patients with myelofibrosis (MF) will be reported in a poster at ASH (Free ASH Whitepaper) 2018 (Press release, Sierra Oncology, NOV 1, 2018, View Source [SID1234530529]). The impact of momelotinib on serum hepcidin, along with markers of iron storage and availability, erythropoiesis and inflammation were investigated to explore the biological mechanisms underlying the favorable effects of momelotinib on MF-associated anemia.

"The results from this translational biology clinical study provide further evidence for momelotinib’s unique anemia benefit," said Dr. Christian Hassig, Chief Scientific Officer of Sierra Oncology. "Moreover, the findings provide clinical evidence that reinforce the differentiated profile of momelotinib as a potent inhibitor of ACVR1, a principal driver of hepcidin production in the liver. As with many inflammatory diseases associated with chronic anemia, myelofibrosis is characterized by high hepcidin, resulting in functional iron deficiency. In myelofibrosis, high levels of hepcidin are inversely correlated with survival. The observed reduction in hepcidin and restoration of iron homeostasis, coupled with net increases in various measures of erythropoiesis, provide important translational biomarker data accounting for the compelling transfusion-independence rates of 34-39% achieved in this transfusion dependent study population."

"As noted in our recent KOL call* featuring Dr. Srdan Verstovsek, one of the investigators in this clinical study, almost every myelofibrosis patient develops anemia and it typically becomes worse over time, often leading to transfusion dependency, yet there are no approved therapies to treat this facet of the disease," stated Dr. Nick Glover, President and Chief Executive Officer of Sierra Oncology. "Momelotinib inhibits JAK1, JAK2 and ACVR1, and is therefore uniquely positioned to address disease-related cytopenia in myelofibrosis, including anemia and transfusion dependency, while also improving splenomegaly and constitutional symptoms."

Sierra is currently preparing for discussions with regulators to determine the registration path for momelotinib and anticipates reporting next steps in the first half of 2019.

About the study (ClinicalTrials.gov Identifier NCT02515630):
In this Phase 2 open-label, translational biology study 41 transfusion-dependent (TD; ≥4 units red blood cells [RBC] transfusion in the 8 weeks prior to first dose of momelotinib) patients with primary or post-ET/PV MF (platelets ≥50 K) received 200 mg momelotinib once daily for 24 weeks.

By week 24, 14 (34.1%, 90% CI: 22.0–48.1%) patients had a ≥12-week transfusion-independent response (TI-R) and 39.0% had no RBC transfusion for ≥8 weeks at any time (90% CI: 26.2-53.1%).
At every study visit, median blood hepcidin decreased 6 hours after dosing with momelotinib. Serum iron, transferrin, hemoglobin, reticulocytes, and hematocrit increased at week 2 in patients with TI-R. Following this peak, serum iron decreased while hemoglobin, hematocrit and platelet count increased through week 24.
Adverse events (AEs) were consistent with previous studies of momelotinib in myelofibrosis, with cough, diarrhea, nausea, and fatigue as the most common. AEs ≥Gr 3 were experienced by 21 patients, most commonly anemia and neutropenia.

Cash Position: As of September 30, 2018, cash, cash equivalents and investments were $164.3 million, as compared to cash and cash equivalents of $38.2 million as of December 31, 2017. This increase was due to net proceeds of $81.3 million from the issuance of Series C Preferred Stock, net proceeds of $75.8 million from Evelo’s initial public offering and $5.0 million of additional drawings from Evelo’s existing debt facility, partially offset by cash used to fund operating activities for the first nine months of 2018. Evelo

expects that its cash, cash equivalents and investments will enable it to fund its planned operating expenses and capital expenditure requirements into the second half of 2020.

Research and Development Expenses: R&D expenses were $11.2 million for the three months ended September 30, 2018, compared to $5.3 million for the three months ended September 30, 2017. The increase of $5.9 million was due primarily to increases in costs related to Evelo’s inflammation and oncology clinical development programs, gut-body network platform expenses as well as increased personnel costs.

General and Administrative Expenses: G&A expenses were $5.2 million for the three months ended September 30, 2018, compared to $2.7 million for the three months ended September 30, 2017. The increase of $2.5 million was due primarily to increased general and administrative personnel costs, professional and consulting fees, and facility expenses supporting Evelo’s growing organization and public company infrastructure.

Net Loss Attributable to Common Stockholders: Net loss attributable to common stockholders was $(15.9) million for the three months ended September 30, 2018, or $(0.50) per basic and diluted share, as compared to a net loss attributable to common stockholders of $(9.9) million for the three months ended September 30, 2017, or $(2.61) per basic and diluted share.
