"Auryxia prescriptions grew 18 percent in the third quarter compared to the second quarter of 2017, reflecting continued adoption of Auryxia; however, this growth was offset by a change in our payer mix," said Greg Madison, president and chief executive officer of Keryx Biopharmaceuticals. "Our confidence in Auryxia remains strong with brand awareness and clinical experience expanding. With the approval of Auryxia for the treatment of iron deficiency anemia in patients with chronic kidney disease, not on dialysis, we are thrilled to have the opportunity to now make Auryxia available to millions of people in the United States living with this condition. With a medicine that can treat two complications of chronic kidney disease, we believe we have a strong foundation from which to build a leading kidney care company."

Third Quarter 2017 Financial Results

Approximately 24,900 Auryxia prescriptions were written in the third quarter of 2017, representing 18 percent growth over the second quarter of 2017.
Keryx reported third quarter 2017 net U.S. Auryxia product sales of $13.6 million; sequential quarter prescription growth was offset by an increase in the gross-to-net adjustment due to a change in the mix of business, with greater prescription volume coming from patients with Medicare Part D insurance.
Given the potential of the additional Auryxia indication on future prescription demand and the dynamics surrounding Auryxia’s payer mix, prescription demand growth and the resulting net U.S. Auryxia product sales in the third quarter, Keryx is withdrawing its 2017 financial guidance.
Recent Business Highlights

The FDA approved Auryxia for an additional indication for the treatment of iron deficiency anemia in adults with chronic kidney disease, not on dialysis. Additional information on the approval is available in a separate press release issued today by Keryx Biopharmaceuticals.
Three abstracts related to Auryxia – one oral presentation and two poster presentations – were presented at the American Society of Nephrology’s (ASN) 2017 Kidney Week. The accepted abstracts are available online on the ASN conference website.
Third Quarter September 30, 2017 Financial Results
"Third quarter net U.S. product sales were lower than anticipated due to a change in the payer mix for Auryxia as well as lower-than-expected growth in prescriptions," said Scott Holmes, senior vice president and chief financial officer of Keryx Biopharmaceuticals. "The growth in Medicare Part D prescriptions, aided by the two large payer contracts added in March and June of this year, outpaced growth in the remainder of the business, leading to a faster acceleration in our gross-to-net adjustment than anticipated. The broad payer coverage across Medicare Part D and commercial plans we have today is critical to continued adoption of Auryxia for the treatment of hyperphosphatemia and positions us well in terms of access for those patients with iron deficiency anemia and chronic kidney disease, not on dialysis."

Total revenues for the quarter ended September 30, 2017 were $15.0 million, compared with $6.3 million during the same period in 2016. Total revenues for the third quarter of 2017 include $13.6 million in net U.S. Auryxia product sales, compared to $5.1 million in the third quarter of 2016. Total revenues also include $1.4 million in license revenue during the third quarter of 2017 and $1.3 million in the third quarter of 2016.

Cost of goods sold for the quarter ended September 30, 2017 were $5.9 million, compared with $18.2 million during the same period in 2016.

Selling, general and administrative expenses for the quarter ended September 30, 2017 were $22.7 million, as compared to $20.5 million during the same period in 2016. The increase was related to the continued commercialization of Auryxia, and preparations for Auryxia’s launch in iron deficiency anemia.

Research and development expenses for the quarter ended September 30, 2017 were $9.3 million, as compared to $8.7 million during the same period in 2016. The increase was primarily related to manufacturing and clinical activities to support the long-term growth of Auryxia.

Net loss for the quarter ended September 30, 2017 was $23.5 million, or $0.20 per share, compared to a net loss of $41.7 million, or $0.39 per share, for the comparable period in 2016.

Cash and cash equivalents as of September 30, 2017 totaled $114.0 million compared to $111.8 million as of December 31, 2016.

About Iron Deficiency Anemia in Adults with Chronic Kidney Disease, not on Dialysis
One out of every seven adults in the U.S. has chronic kidney disease. This disease carries a significant burden with complex issues requiring many different medications. A common complication of CKD is iron deficiency anemia. Iron is an essential mineral for the human body and is typically obtained from the diet. It is a critical component of human blood as it is necessary to make healthy red blood cells. People with chronic kidney disease often have anemia as a result of insufficient iron (called iron deficiency anemia) and do not produce enough hemoglobin, the component of the red blood cell that carries oxygen throughout the body. Iron deficiency anemia can negatively impact a patient’s quality of life and is associated with cardiovascular complications and increased mortality risk. Based on market research, Keryx estimates that nephrologists currently treat 650,000 people for iron deficiency anemia who have chronic kidney disease and are not on dialysis. There are estimated to be an additional 250,000 – 400,000 people under the care of a nephrologist who have chronic kidney disease and iron deficiency anemia but are not treated today. The prevalence and severity of iron deficiency anemia increases as kidney disease progresses.

About Auryxia (ferric citrate) tablets
Auryxia (ferric citrate) was approved by the U.S. Food and Drug Administration on September 5, 2014 for the control of serum phosphorus levels in adults with chronic kidney disease on dialysis and approved on November 6, 2017 for the treatment of iron deficiency anemia in adults with chronic kidney disease not on dialysis. Auryxia tablets were designed to contain 210 mg of ferric iron, equivalent to 1 gram of ferric citrate, and offers convenient mealtime dosing. The starting dose of Auryxia for the treatment of hyperphosphatemia for patients on dialysis is six tablets per day (two per meal) and for the treatment of iron deficiency anemia in patients not on dialysis is three tablets per day (one per meal). For more information about Auryxia and the U.S. full prescribing information, please visit www.Auryxia.com.

IMPORTANT U.S. SAFETY INFORMATION FOR AURYXIA (ferric citrate)

CONTRAINDICATION

AURYXIA (ferric citrate) is contraindicated in patients with iron overload syndromes, e.g., hemochromatosis.

WARNINGS AND PRECAUTIONS

Iron Overload: Increases in serum ferritin and transferrin saturation (TSAT) were observed in clinical trials with AURYXIA in patients with chronic kidney disease (CKD) on dialysis treated for hyperphosphatemia, which may lead to excessive elevations in iron stores. Assess iron parameters prior to initiating AURYXIA and monitor while on therapy. Patients receiving concomitant intravenous (IV) iron may require a reduction in dose or discontinuation of IV iron therapy.
Risk of Overdosage in Children Due to Accidental Ingestion: Accidental ingestion and resulting overdose of iron-containing products is a leading cause of fatal poisoning in children under 6 years of age. Advise patients of the risks to children and to keep AURYXIA out of the reach of children.
ADVERSE REACTIONS

Most common adverse reactions with AURYXIA were:

Hyperphosphatemia in CKD on Dialysis: Diarrhea (21%), discolored feces (19%), nausea (11%), constipation (8%), vomiting (7%) and cough (6%)
Iron Deficiency Anemia in CKD Not on Dialysis: Discolored feces (22%), diarrhea (21%), constipation (18%), nausea (10%), abdominal pain (5%) and hyperkalemia (5%)
SPECIFIC POPULATIONS

Pregnancy and Lactation: There are no available data on AURYXIA use in pregnant women to inform a drug-associated risk of major birth defects and miscarriage. However, an overdose of iron in pregnant women may carry a risk for spontaneous abortion, gestational diabetes and fetal malformation. Data from rat studies have shown the transfer of iron into milk, hence, there is a possibility of infant exposure when AURYXIA is administered to a nursing woman.
To report suspected adverse reactions, contact Keryx Biopharmaceuticals at 1-844-445-3799

The Company continues to expand its pipeline, and recently announced that it has entered into an exclusive worldwide license agreement with Vitae Pharmaceuticals, Inc., a subsidiary of Allergan plc, for a portfolio of preclinical, orally-available small molecule inhibitors of the interaction of Menin with the Mixed Lineage Leukemia ("MLL") protein. Syndax plans to initially study these compounds for the treatment of a genetically-defined subset of acute leukemias with chromosomal rearrangements in the MLL gene ("MLL-r").

All four cohorts of ENCORE 601, an open-label, Simon two-stage design, Phase 1b/2 clinical trial evaluating the combination of entinostat, the Company’s class I selective HDAC inhibitor, plus Merck’s anti-PD-1 (programmed death receptor-1) blocking therapy, KEYTRUDA, continue to proceed on schedule. Enrollment in the first stage of the cohort of patients with microsatellite stable colorectal cancer (MSS-CRC) is complete, and a decision on whether to continue to the second stage is expected in the first quarter of 2018. Enrollment in the second stage of the PD-(L)1 refractory non-small cell lung cancer (NSCLC) cohort is complete, and Syndax expects to share updated data from this cohort in the first half of 2018.

"As we near the end of 2017, the momentum we’ve built throughout the year continues to yield meaningful progress and growth for our pipeline of potential best-in-class candidates," said Briggs W. Morrison, M.D., Chief Executive Officer of Syndax. "The recent expansion of our pipeline represents what we believe will be a long-term value enhancing transaction for the Company, while also potentially changing the treatment paradigm for acute leukemic patients harboring MLL translocations, where there exists a high unmet need. For entinostat, the ENCORE 601 program remains on track and we look forward to presenting data from both NSCLC cohorts, as well as biomarker data from the melanoma cohort, at the upcoming SITC (Free SITC Whitepaper) Annual Meeting. We are also developing a global registration plan for entinostat in combination with a PD-1 inhibitor for patients with PD-1 refractory melanoma. We anticipate sharing details of our plan in the first half of 2018, in parallel with the full Phase 2 data from the melanoma cohort of ENCORE 601.

Pipeline Updates

The Phase 3 registration trial of entinostat plus exemestane in advanced HR+, HER2- breast cancer, E2112, is 83% enrolled as of the end of October. ECOG-ACRIN Cancer Research Group, the trial sponsor, has notified the Company that the Data Safety Monitoring Committee (DSMC) completed the final progression free survival analysis and the first interim analysis for overall survival. The results of this analysis are held confidentially by the ECOG-ACRIN study statistician and the DSMC. No communication regarding this analysis will be released until completion of enrollment, which ECOG-ACRIN expects will occur in the first half of 2018.
The ENCORE 601 cohort enrolling NSCLC patients naïve to PD-(L)1 therapy has satisfied the pre-specified efficacy criteria for advancement to the second stage, with ≥ 4 responses out of 17.
Enrollment in the second stage of the ENCORE 601 cohort enrolling patients with PD-(L)1 refractory NSCLC is complete. Data from this cohort is expected to be available in the first half of 2018.
Following a meeting with the U.S. Food and Drug Administration (FDA) in June, the Company is continuing to meet with individual regulatory agencies in Europe to align on a global registration plan for entinostat in combination with a PD-1 inhibitor for patients with PD-(L)1 refractory melanoma. The Company anticipates being in a position to outline a regulatory plan for this indication around the time that full Phase 2 data from the melanoma cohort of ENCORE 601 are available in the first half of 2018.
An oral presentation highlighting the data from stage one of both the ENCORE 601 NSCLC cohorts, as well as a poster presentation covering the biomarker data from the ENCORE 601 melanoma cohort, will be presented at the upcoming Society of Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) Annual Meeting. The Company anticipates sharing full Phase 2 trial data from both the PD-(L)1 refractory NSCLC and melanoma cohorts at a medical congress in the first half of 2018. Details on both SITC (Free SITC Whitepaper) presentations are available here.
Enrollment in the first stage of the cohort enrolling patients with microsatellite stable (MSS)–CRC is complete, and a decision on whether to advance to the second stage is expected in the first half of 2018. At least 2 confirmed objective responses are required to proceed to the second stage.
Enrollment continues in the ENCORE 602 and ENCORE 603 trials, both of which are aimed at exploring the ability of entinostat to enhance the efficacy of checkpoint (PD-L1) inhibitor therapies. ENCORE 602, the Phase 1b/2 clinical trial evaluating the combination of entinostat plus Genentech’s PD-L1 inhibitor, TECENTRIQ, in patients with triple negative breast cancer, is now expected to complete enrollment in the Phase 2 portion in the first half of 2018, with results anticipated in the second half of the year. ENCORE 603, the Phase 1b/2 clinical trial evaluating entinostat in combination with Pfizer/Merck KGaA’s BAVENCIO in patients with ovarian cancer, continues to enroll patients into the Phase 2 portion and is on track to complete enrollment in the first half of 2018, with results anticipated in the first half of 2019.
Dosing of patients with solid tumors in the Phase 1 multiple ascending dose (MAD) clinical trial of SNDX-6352, the Company’s anti-CSF-1R monoclonal antibody, has commenced. A poster highlighting the safety, pharmacokinetic and pharmacodynamic data from the single ascending dose (SAD) trial of SNDX-6352 in healthy volunteers will be presented at the upcoming SITC (Free SITC Whitepaper) Annual Meeting. Details on the presentation are available here.
The Company entered into an exclusive worldwide license agreement with Vitae Pharmaceuticals, Inc., a subsidiary of Allergan plc, for a portfolio of preclinical, orally-available small molecule inhibitors of the interaction of Menin with the MLL protein. These compounds have potential application in the treatment of a genetically-defined subset of acute leukemias with chromosomal rearrangements in the MLL gene ("MLL-r"). The Company expects to initiate clinical trials in 2019.

Third Quarter 2017 Financial Results

As of September 30, 2017, Syndax had cash, cash equivalents and short-term investments of $120.6 million and 22.3 million shares issued and outstanding. In October 2017, the Company reported the sale of 2.0 million common shares in a registered direct offering with net proceeds of $24.8 million.

Third quarter 2017 research and development expenses decreased to $12.2 million from $12.3 million for the comparable period in the prior year. The decrease was primarily due to increased clinical trial activities of $3.9 million and increased employee compensation expense of $0.9 million, offset by a $5.0 million upfront payment in 2016 related to the in-license of SNDX-6352 from UCB. The increase in clinical trial activities was primarily due to additional cohorts added to ENCORE 601, increased activities in ENCORE 602 and ENCORE 603, costs related to SNDX-6352, Phase 1 clinical pharmacology trials and CMC activities. The increase in employee compensation costs was primarily due to increased headcount.

General and administrative expenses totaled $3.6 million during the third quarter of 2017 compared with $3.3 million in the comparable period in the prior year. The increase in general and administrative expenses was primarily due to an increase in non-cash stock-based compensation of $0.4 million and an increase in salary expense of $0.2 million due to increased headcount, offset by decreased legal fees of $0.3 million.

For the three months ended September 30, 2017, Syndax reported a net loss attributable to common stockholders of $15.1 million, or $0.68 per share, compared to $15.0 million, or $0.84 per share, for the comparable prior year period.

Financial Guidance

Today the Company provided operating expense guidance for the fourth quarter and full year 2017. For the fourth quarter and full year 2017, research and development expenses are expected to be $15 to $18 million and $47 to $50 million, respectively, and total operating expenses are expected to be $19 to $22 million and $63 to $66 million, respectively. Research and development expenses for the fourth quarter includes $5.0 million paid to Allergan in connection with the Menin-MLL license. This expense will be offset on a cash basis with a $5.0 million development milestone earned in the fourth quarter under our agreement with KHK.

On November 7, 2017 Calithera Biosciences, Inc. (Nasdaq:CALA), a clinical stage pharmaceutical company focused on discovering and developing novel small molecule drugs directed against tumor metabolism and tumor immunology targets for the treatment of cancer reported that initial data from the ongoing trial of CB-839 in combination with Opdivo in patients with melanoma, renal cell carcinoma and non-small cell lung cancer will be presented Saturday, November 11th, 2017, at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) Annual Meeting (Press release, Calithera Biosciences, NOV 7, 2017, View Source [SID1234535250]). Calithera also announced it has expanded its existing clinical collaboration with Bristol-Myers Squibb, evaluating CB-839 in combination with Opdivo. CB-839 is an orally bioavailable glutaminase inhibitor currently in Phase 2 trials, and Opdivo is a PD-1 immune checkpoint inhibitor designed to overcome immune suppression.

"This trial is designed to include patients who are currently receiving checkpoint inhibitor therapy and experiencing disease progression at the time of enrollment. There is significant unmet need among these patients, and the responses observed would not be expected with treatment with Opdivo alone in this population," said Susan M. Molineaux, Ph.D., founder, Chief Executive Officer and President of Calithera Biosciences. "The expanded clinical collaboration with Bristol-Myers Squibb will help us pursue our strategy of developing CB-839 in combination with Opdivo with the hope of improving treatment options for patients with cancer."

Calithera is conducting a Phase 1/2 trial (NCT02771626) in collaboration with Bristol-Myers Squibb designed to evaluate the safety, tolerability and efficacy of CB-839 in combination with Opdivo in patients with renal cell carcinoma, melanoma or non-small cell lung cancer. The study will be expanded to enroll additional melanoma patients. As part of the expanded collaboration, melanoma development costs will be shared, and a joint development committee will be established to guide the development and regulatory strategy.

The ongoing study enrolled three cohorts of patients who have received a checkpoint inhibitor (PD-1/PD-L1) in the most recent line of therapy.

Among 16 evaluable melanoma patients, all of whom were progressing on a checkpoint inhibitor at study entry, one patient achieved a complete response and two patients achieved partial responses. The overall response rate in this cohort was 19%, and the overall disease control rate was 44%.
Among six evaluable non-small cell lung cancer patients, all of whom were progressing on a checkpoint inhibitor at study entry, 67% experienced stable disease.
Among eight evaluable renal cell carcinoma patients, 75% were progressing and 25% had stable disease at study entry.

Stable disease was achieved in 75%, all of whom were progressing on a checkpoint inhibitor at study entry. The study enrolled one cohort of renal cell carcinoma patients who have received a checkpoint inhibitor in any prior line of therapy, but never achieved a response to checkpoint therapy.

Among seven evaluable checkpoint inhibitor experienced renal cell carcinoma patients, with a median of four prior lines of therapy, 57% experienced stable disease.

The study enrolled one cohort of renal cell carcinoma patients who were previously treated with VEGF inhibiting therapy, and were naïve to checkpoint inhibitors. Among 19 evaluable checkpoint inhibitor naïve renal cell carcinoma patients, four patients (21%) achieved a partial response and disease control rate was 74%. Fifty percent of the enrolled patients remain on study treatment.

An analysis of all safety evaluable patients demonstrated that CB-839 was well tolerated when combined with Opdivo in melanoma, renal cell carcinoma and non-small cell lung cancer patients. During dose escalation of the combination therapy, there was one report of dose limiting Grade 3 ALT increase, however no maximum tolerated dose was reported. The majority of adverse events reported have been mild to moderate with the most common being fatigue, nausea and photophobia. With 3.7% immune-related adverse events Grade ≥ 3, the data suggest there was no apparent increase in the rate or severity of immune related events compared to historical rates.

Dr. Funda Meric-Bernstam from MD Anderson Cancer Center will present the results on Saturday, November 11, 2017, in an oral and poster session (Abstract #O16), "A phase 1/2 study of CB-839, a first-in-class glutaminase inhibitor, combined with nivolumab in patients with advanced melanoma, renal cell carcinoma or non-small cell lung cancer." The oral presentation slides and the poster will be available on the Company’s website in the publication section at View Source

Calithera will webcast a clinical update on CB-839 on Saturday, November 11th at 3:30 p.m. Pacific Time/ 6:30 p.m. Eastern Time. The call can be accessed by dialing (855) 783-2599 (domestic) or (631) 485-4877 (international), and referring to conference ID 1878409. To access the live audio webcast or the subsequent archived recording, visit the Investors section of the Calithera website at www.calithera.com. The webcast will be recorded and available for replay on Calithera’s website for 30 days.
