On August 8, 2018 Clovis Oncology, Inc. (NASDAQ: CLVS) reported the randomization of the first patient in the Phase 3 ATHENA trial evaluating the combination of Clovis’ Rubraca(rucaparib), a poly (ADP ribose) polymerase inhibitor (PARP), and Bristol-Myers Squibb’s PD-1 inhibitor, OPDIVO (nivolumab), for the treatment of advanced ovarian cancer (Press release, Clovis Oncology, AUG 8, 2018, View Source [SID1234528526]). ATHENA, sponsored by Clovis, is part of a clinical collaboration with Bristol-Myers Squibb and is being conducted in association with the Gynecologic Oncology Group (GOG) and the European Network for Gynecological Oncological Trials (ENGOT). GOG and ENGOT are the two largest cooperative groups in the U.S. and Europe dedicated to the treatment of gynecological cancers.

"I am pleased the GOG and ENGOT are conducting the first trial designed to investigate whether the combination of a PARP inhibitor and PD-1 blocking antibody can demonstrate not only an improvement in progression-free survival in the first-line maintenance setting for women with advanced ovarian cancer, but also whether the combination can change the natural course of the disease by delaying or reducing recurrence following front-line therapy," said Brad Monk, M.D., FACS, FACOG, Arizona Oncology (US Oncology Network), Professor, Gynecologic Oncology at University of Arizona and Creighton University, Medical Director of US Oncology Research Gynecology program in Phoenix, Arizona and Lead Investigator of the ATHENA trial.

"Rubraca combination trials such as ATHENA are encouraging to see, because the possible implications are particularly meaningful for women with advanced ovarian cancer, who need a wide range of treatment options," said Dr. Rebecca Kristeleit, Clinical Senior Lecturer and Consultant Medical Oncologist, University College London, U.K. and ATHENA ENGOT/Non-U.S. Lead Investigator. "The participation by the GOG and the ENGOT in the evaluation of a PARP inhibitor in combination with a PD-1 agent reflects the interest around this approach."

ATHENA is a Phase 3, randomized, multinational, double-blind, placebo-controlled, four-arm trial evaluating Rubraca and Opdivo as maintenance treatment following response to front-line treatment in newly-diagnosed ovarian cancer patients. Response to treatment will be analyzed based on homologous recombination (HR) status of tumor samples. The primary endpoint is investigator assessed progression-free survival (PFS); secondary endpoints include overall survival (OS), objective response rate (ORR), duration of response (DOR), and safety.

"The initiation of the Phase 3 ATHENA trial is an important milestone for Clovis and a critical step towards helping women with advanced ovarian cancer, who are in need of new treatment options. We are particularly excited about the potential clinical utility of Rubraca in combination with Opdivo in this setting," said Patrick J. Mahaffy, President and Chief Executive Officer of Clovis Oncology. "The importance of this trial is also underscored by the participation of ENGOT and GOG, which we anticipate may facilitate enrollment."

The trial will enroll approximately 1,000 ovarian cancer patients at clinical trial centers in the United States and internationally. More information about the trial is available at www.clinicaltrials.gov, identifier NCT03522246.

About Rubraca (rucaparib)

Rubraca is an oral, small molecule inhibitor of PARP1, PARP2 and PARP3 being developed in multiple tumor types, including ovarian, metastatic castration-resistant prostate, and bladder cancers, as monotherapy, and in combination with other anti-cancer agents. Exploratory studies in other tumor types are also underway. Clovis holds worldwide rights for Rubraca. Rubraca is an unlicensed medical product outside of the U.S. and Europe.

Rubraca EU Authorized Use

Rubraca is licensed for adult patients with platinum sensitive, relapsed or progressive, BRCA mutated (germline and/or somatic), high-grade epithelial ovarian, fallopian tube, or primary peritoneal cancer, who have been treated with two or more prior lines of platinum based chemotherapy, and who are unable to tolerate further platinum based chemotherapy.

Click here to access the current Summary of Product Characteristics. Healthcare professionals should report any suspected adverse reactions via their national reporting systems.

Rubraca U.S. FDA Approved Indications and Important Safety Information

Rubraca is indicated as monotherapy for the maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in a complete or partial response to platinum-based chemotherapy.

Rubraca is indicated as monotherapy for the treatment of adult patients with deleterious BRCA mutation (germline and/or somatic) associated epithelial ovarian, fallopian tube, or primary peritoneal cancer who have been treated with two or more chemotherapies and selected for therapy based on an FDA-approved companion diagnostic for Rubraca.

Select Important Safety Information

Myelodysplastic Syndrome (MDS)/Acute Myeloid Leukemia (AML) occur uncommonly in patients treated with Rubraca, and are potentially fatal adverse reactions. In approximately 1,100 treated patients, MDS/AML occurred in 12 patients (1.1%), including those in long term follow-up. Of these, 5 occurred during treatment or during the 28-day safety follow-up (0.5%). The duration of Rubraca treatment prior to the diagnosis of MDS/AML ranged from 1 month to approximately 28 months. The cases were typical of secondary MDS/cancer therapy-related AML; in all cases, patients had received previous platinum-containing regimens and/or other DNA damaging agents. Do not start Rubraca until patients have recovered from hematological toxicity caused by previous chemotherapy (≤ Grade 1).

Monitor complete blood counts for cytopenia at baseline and monthly thereafter for clinically significant changes during treatment. For prolonged hematological toxicities (> 4 weeks), interrupt Rubraca or reduce dose (see Dosage and Administration (2.2) in full Prescribing Information) and monitor blood counts weekly until recovery. If the levels have not recovered to Grade 1 or less after 4 weeks or if MDS/AML is suspected, refer the patient to a hematologist for further investigations, including bone marrow analysis and blood sample for cytogenetics. If MDS/AML is confirmed, discontinue Rubraca.

Based on its mechanism of action and findings from animal studies, Rubraca can cause fetal harm when administered to a pregnant woman. Apprise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment and for 6 months following the last dose of Rubraca.

Most common adverse reactions in ARIEL3 (≥ 20%; Grade 1-4) were nausea (76%), fatigue/asthenia (73%), abdominal pain/distention (46%), rash (43%), dysgeusia (40%), anemia (39%), AST/ALT elevation (38%), constipation (37%), vomiting (37%), diarrhea (32%), thrombocytopenia (29%), nasopharyngitis/upper respiratory tract infection (29%), stomatitis (28%), decreased appetite (23%), and neutropenia (20%).

Most common laboratory abnormalities in ARIEL3 (≥ 25%; Grade 1-4) were increase in creatinine (98%), decrease in hemoglobin (88%), increase in cholesterol (84%), increase in alanine aminotransferase (ALT) (73%), increase in aspartate aminotransferase (AST) (61%), decrease in platelets (44%), decrease in leukocytes (44%), decrease in neutrophils (38%), increase in alkaline phosphatase (37%), and decrease in lymphocytes (29%).

Most common adverse reactions in Study 10 and ARIEL2 (≥ 20%; Grade 1-4) were nausea (77%), asthenia/fatigue (77%), vomiting (46%), anemia (44%), constipation (40%), dysgeusia (39%), decreased appetite (39%), diarrhea (34%), abdominal pain (32%), dyspnea (21%), and thrombocytopenia (21%).

Most common laboratory abnormalities in Study 10 and ARIEL2 (≥ 35%; Grade 1-4) were increase in creatinine (92%), increase in alanine aminotransferase (ALT) (74%), increase in aspartate aminotransferase (AST) (73%), decrease in hemoglobin (67%), decrease in lymphocytes (45%), increase in cholesterol (40%), decrease in platelets (39%), and decrease in absolute neutrophil count (35%).

Co-administration of Rubraca can increase the systemic exposure of CYP1A2, CYP3A, CYP2C9, or CYP2C19 substrates, which may increase the risk of toxicities of these drugs. Adjust dosage of CYP1A2, CYP3A, CYP2C9, or CYP2C19 substrates, if clinically indicated. If co-administration with warfarin (a CYP2C9 substrate) cannot be avoided, consider increasing frequency of international normalized ratio (INR) monitoring. Because of the potential for serious adverse reactions in breast-fed children from Rubraca, advise lactating women not to breastfeed during treatment with Rubraca and for 2 weeks after the last dose. You may report side effects to the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. You may also report side effects to Clovis Oncology, Inc. at 1-844-258-7662.

Second Quarter 2018 Financial Results

Cash, cash equivalents and short-term investments totaled $335.1 million as of June 30, 2018, compared to $374.1 million as of December 31, 2017.

Revenue was $21.3 million for the three months ended June 30, 2018, compared to $8.8 million for the three months ended June 30, 2017. The increase was primarily attributable to the recognition of $9.9 million in revenue of the $21 million (net of the associated sublicense fee of $4 million) milestone payment from AbbVie related to the clearance of the CX-2029 IND, an increase of $1.6 million in revenue related to the Amgen collaboration, an increase of $1.4 million in revenue related to the BMS collaboration, and an increase of $0.7 million in revenue from the collaboration extension agreement with ImmunoGen, partially offset by a decrease in revenue of $0.5 million from the termination of the Pfizer collaboration in March 2018.

Research and development expenses decreased by $2.5 million during the three months ended June 30, 2018 compared to the corresponding period in 2017. The net decrease was primarily attributed to a $10.0 million sublicense payment to UCSB in Q2 2017, which was triggered by the $200 million upfront payment from BMS, offset by a $4.6 million increase in lab contracts and services and clinical trial expenses related to CX-072 and CX-2009 into phase 1 / 2 clinical development, an increase of $2.5 million in personnel related expenses due to an increase in headcount and a $0.4 million sublicense fee payable to UCSB for the IND success criteria achieved on the AbbVie CD71 Agreement in Q2 2018.

General and administrative expenses increased by $3.0 million during the three months ended June 30, 2018 compared to the corresponding period in 2017. This increase was largely attributed to an increase of $1.4 million in personnel related expenses due to increases in headcount, an increase of $1.0 million in consulting expenses and an increase of $0.5 million in legal fees.

On August 8, 2018 PDL BioPharma, Inc. ("PDL" or the "Company") (NASDAQ: PDLI) reported its financial results for the three and six months ended June 30, 2018 including (Press release, PDL BioPharma, AUG 8, 2018, View Source [SID1234528766]):

Second Quarter Financial Highlights

Total revenues of $46.6 million.

GAAP net loss attributable to PDL’s shareholders of $112.3 million or $(0.76) per share.

GAAP net loss includes a one-time $133.3 million, net of tax, non-cash accounting charge related to the impairment of an intangible asset from Noden Pharma DAC, due to the increased probability of a generic version of aliskiren being launched in the United States by Anchen, offset by a $19.7 million, net of tax, non-cash decrease in the fair value of the contingent liability related to a reduced estimate of the probability in paying milestones to Novartis for Tekturna.

Non-GAAP net income attributable to PDL’s shareholders of $14.7 million. A reconciliation of GAAP to non-GAAP financial results can be found in Table 3 at the end of this news release.

Cash, cash equivalents, short-term investments and other investments of $395.7 million as of June 30, 2018.

Repurchased 6.8 million shares of common stock in the open market during the quarter for $19.4 million.

"Our financial results for the second quarter reflect higher product sales resulting from our change in strategy to equity and product investments, and we continue to have a strong cash balance to pursue acquisitions. While we are disappointed with the write down of the Noden asset, the impairment is not an indication of the performance of the business this quarter, but rather is based upon uncertainty in the future generic aliskiren competition in the United States," said John P. McLaughlin, CEO of PDL.

"Last week we announced an amended agreement with Depomed to purchase Depomed’s remaining interests in future royalties for $20 million in a transaction we view as highly attractive to our shareholders," he added. "While we are shifting our strategy away from royalty agreements, our familiarity with the Depomed assets and our past success with them supported this investment decision. We expect to begin realizing a return on this investment by late 2020 with meaningful cash returns expected through 2026."

Revenue Highlights

Total revenues of $46.6 million for the three months ended June 30, 2018 included:
◦
Product revenues of $31.8 million, which consisted of $25.9 million from sales of Tekturna and Tekturna HCT in the United States and Rasilez and Rasilez HCT in the rest of the world (collectively, the Noden Products), and $5.9 million for product sales of the LENSAR Laser System;
◦
Net royalty payments from acquired royalty rights and a change in fair value of the royalty rights assets of $12.8 million, which consisted of the change in estimated fair value of our royalty right assets, primarily related to the Depomed royalty asset;

Royalties from PDL’s licensees to the Queen et al. patents of $1.2 million, which consisted of royalties earned on sales of Tysabri; and
◦
Interest revenue from note receivable investment to CareView Communications of $0.8 million.

Total revenues for the second quarter of 2018 were $46.6 million, compared with $143.8 million for the second quarter of 2017, reflecting PDL’s strategic shift to a pharmaceutical business model and the decline in royalty income from the expired Queen et al. patents.
◦
Product revenues were $31.8 million, a 69% increase from $18.8 million for the prior year due to sales of the Noden Products and the LENSAR Laser System, the latter of which PDL did not begin to recognize until May 2017. Product revenues accounted for 68% of total revenues compared with 13% in the second quarter of 2017;
◦
Product revenues from Noden Products were $10.4 million in the U.S. and $15.5 million in the rest of the world.
◦
PDL recognized $12.8 million in revenue from royalty rights – change in fair value, compared with $83.7 million in the prior-year period. The decrease was primarily due to a higher prior year royalty rights – change in fair value as a result of the increase in fair value of the Depomed, Inc. royalty asset in the second quarter of 2017 based upon revised future cash flows;
◦
PDL received $19.4 million in net cash royalties from its royalty rights for the second quarter of 2018, compared with $34.6 million for the prior-year period. The decrease is mainly due to the launch of the authorized generic for Glumetza in February 2017 sold by a subsidiary of Bausch Health Companies Inc. (formerly Valeant Pharmaceuticals International, Inc.) and included a retroactive payment in the second quarter of 2017;
◦
Royalties from PDL’s licensees to the Queen et al. patents of $1.2 million, compared with $16.3 million for the second quarter of 2017 as product supply of Tysabri manufactured prior to patent expiry in the U.S. have been extinguished and ex-U.S. product supplies are rapidly being depleted; and
◦
Interest revenues decreased primarily due to the sale of the kaléo, Inc. note receivable in September 2017.

Total revenues for the six months ended June 30, 2018, were $85.1 million, compared with $189.3 million for the prior-year period:
◦
Product revenues were $55.1 million, a 75% increase from $31.4 million for the prior-year period. Product revenues for 2018 consisted of $44.2 million from sales of the Noden Products and $10.9 million for product sales of the LENSAR Laser System;
◦
PDL recognized $23.9 million in net royalty payments from acquired royalty rights and a change in fair value of the royalty rights assets, compared with $96.9 million for the prior-year period;
◦
PDL received $38.0 million in net cash royalties from its royalty rights year-to-date 2018, compared with $48.1 million for the prior-year period;
◦
Royalties from PDL’s licensees to the Queen et al. patents of $4.0 million, compared with $30.4 million for the prior-year period; and
◦
Interest revenue from note receivable investment to CareView Communications of $1.5 million.

Operating Expense Highlights

Operating expenses for the three months ended June 30, 2018 of $171.7 million increased $140.6 million from $31.1 million for the three months ended June 30, 2017. The increase was a result of the impairment of the Noden intangible asset of $152.3 million due to the increased probability of a generic version of aliskiren being launched in the United States, partially offset by the $22.5 million decrease in fair value of the contingent liability related to reduced estimate in the probabilities in paying milestones to Novartis for Tekturna.

Cost of product revenue for the three months ended June 30, 2018 increased as a result of the Noden Products and LENSAR contributing additional cost of product revenue of $8.4 million and $1.6 million, respectively, due to increased revenue from Noden Products and recognition of costs of goods for ex-U.S. revenue and increased revenue from LENSAR, which PDL did not begin to recognize until May 2017. General and administrative expenses of $14.5 million, increased compared with $11.3 million a year ago, with the increase due to a full quarter of expenses from LENSAR in 2018 versus a partial quarter as a result of its acquisition in May 2017, operation growth for Noden and expenses related to business development activities. Sales and marketing expenses were $5.4 million, compared with $3.6 million in the prior-year period, with the increase due to an increase in marketing efforts for Noden and LENSAR, and research and development costs decreased based upon the completion of a pediatric trial for Tekturna.

Operating expenses for the six months ended June 30, 2018 were $205.9 million, a $147.9 million increase from $58.0 million for the prior-year period, with the increase primarily a result of the impairment of the Noden intangible asset of $152.3 million, as well as a result of Noden and LENSAR contributing additional cost of product revenue of $14.0 million and $4.0 million, respectively, which was due to increased revenue in Noden and recognition of costs of goods for ex-U.S. revenue and increased revenue from LENSAR, which PDL did not begin to recognized until May 2017, partially offset by the decrease in fair value of the contingent liability.

Stock Repurchase Programs

PDL repurchased 8.2 million shares of its common stock under the $25.0 million share repurchase program during the six months ended June 30, 2018, for an aggregate purchase price of $23.6 million, or an average cost of $2.89 per share, including trading commission. All shares repurchased were retired.

From July 1, 2018 to July 5, 2018, the Company completed this stock repurchase program with the repurchase of 0.6 million shares of its common stock at a weighted average price of $2.44 per share, for a total of $1.4 million.

Since initiating its first stock repurchase program in March 2017, the Company has used $55.0 million to repurchase a total of 22.0 million shares of its common stock.

Other Financial Highlights

PDL had cash, cash equivalents, short-term investments and other investments of $395.7 million as of June 30, 2018, compared with $532.1 million as of December 31, 2017.

The reduction in cash balance for the six months ended June 30, 2018 was primarily a result of the retiring of the remaining $126.4 million of principal from PDL’s 4.0% Convertible Senior Notes due 2018, plus $2.6 million of accrued interest, and common stock repurchases of $23.6 million.

Vical recently announced plans to explore a range of strategic options to enhance shareholder value. The company retained MTS Health Partners, L.P. to assist in the strategic review process. There is no set timetable for the review process and there can be no assurance that the process will result in a transaction.

Vical had cash and investments of $54.3 million at June 30, 2018. The Company’s cash burn for the second quarter of 2018 was $4.0 million, which was consistent with the Company’s full year 2018 guidance of between $20 million and $24 million. The Company anticipates ending 2018 with a minimum of $40 million, which, in the absence of a strategic transaction, Vical believes to be sufficient to fund operations through the announcement of top-line data from its Phase 2 clinical trial of VL-2397, expected in 2020.

Program updates include:

VL-2397 Antifungal Candidate

The multinational Phase 2 registration trial comparing VL‑2397 to standard first-line treatment for invasive aspergillosis in immunocompromised adults with acute leukemia or recipients of an allogeneic hematopoietic cell transplant is ongoing (ClinicalTrials.gov Identifier: NCT03327727). Vical expects to conduct the trial in approximately 40 major cancer and transplantation centers in North America, Europe and Asia. The FDA has advised that VL‑2397 would be eligible for a Limited Use Indication (LUI) approval for the treatment of invasive aspergillosis for patients with limited treatment options. The FDA has also granted Vical Qualified Infectious Disease Product (QIDP), Orphan Drug and Fast Track designations for VL‑2397 for the treatment of invasive aspergillosis. VL-2397 has a novel mechanism of antifungal action and could be the first therapeutic in a new class of antifungals.
VR-CHB01 Hepatitis B Virus (HBV) Therapeutic Candidate

The Company is pursuing preclinical development of a novel treatment for chronic HBV infection based on its DNA and lipid-delivery technologies. The initial aim of this program will be to demonstrate proof of concept for inhibiting HBV infection in an in vivo model. The Company expects to complete the initial stage of preclinical development in the fourth quarter of 2018.

On August 7, 2018 Syndax Pharmaceuticals, Inc. ("Syndax," the "Company" or "we") (Nasdaq: SNDX), a clinical stage biopharmaceutical company developing an innovative pipeline of cancer therapies, reported its financial results for the second quarter ended June 30, 2018. In addition, the Company provided a clinical and business update (Press release, Syndax, AUG 7, 2018, View Source [SID1234528501]). As of June 30, 2018, Syndax had $98.4 million in cash, cash equivalents and short-term investments.

"We made great progress across multiple programs during the first half of this year, including presentation of data from all three cohorts of ENCORE 601 and completion of target enrollment in ENCORE 602 and 603. We also initiated the first combination trial for the SNDX-6352 program, which will evaluate its safety in combination with durvalumab (IMFINZI)," said Briggs W. Morrison, M.D., Chief Executive Officer of Syndax. "We continue to expect the progression free survival results from E2112, our ongoing Phase 3 trial of entinostat plus exemestane in HR+, HER2- breast cancer, later this quarter, and the third prespecified interim analysis of overall survival in November. We also anticipate sharing next steps for the entinostat-KEYTRUDA (pembrolizumab) combination program in both non-small cell lung cancer and melanoma by the end of the year."

The Company also announced today that it plans to initiate a Phase 1 trial of its monoclonal antibody inhibitor of Colony-Stimulating Factor 1 Receptor (CSF-1R), SNDX-6352, in patients with chronic graft versus host disease (cGVHD). Enrollment in this trial is anticipated to begin by the end of the year, with initial data expected in the second half of 2019.

"We are excited to begin the evaluation of SNDX-6352 as a treatment for cGVHD, a novel clinical path for a CSF1-R inhibitor," said Michael L. Meyers, M.D., Ph.D., Chief Medical Officer of Syndax. "Preclinical findings support that CSF-1R inhibition may serve as an effective approach for treating this debilitating, often deadly side effect of allogenic hematopoietic stem cell transplantation. We look forward to learning more about the potential of SNDX-6352 in this indication."

Pipeline Updates

The Phase 3 registration trial of entinostat plus exemestane in advanced hormone receptor positive, human epidermal growth factor receptor 2 negative (HR+, HER2-) breast cancer, E2112, is 98% enrolled as of the end of July. ECOG-ACRIN Cancer Research Group, the trial sponsor, had notified the Company that the Data Safety Monitoring Committee (DSMC) completed the final progression free survival (PFS) analysis in November 2017. The trial is proceeding as planned, and Syndax continues to anticipate that enrollment will be complete in the third quarter of 2018, at which time the result of the PFS analysis will be released to the Company. In addition, interim overall survival (OS) analyses are scheduled to occur every May and November. Two interim OS analyses have already occurred, with the next analysis expected this November.

The Company presented data from a subset of PD-(L)1 refractory non-small cell lung cancer (NSCLC) patients enrolled in the expanded Phase 2 ENCORE 601 cohort (n = 57) at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting in June. Updated data from all patients (n = 76) enrolled in this cohort will be presented at the World Conference on Lung Cancer Meeting in Toronto next month, including updated results from the Company’s biomarker analyses. The Company expects to communicate its development plans for entinostat in this indication in the fourth quarter.

The Company presented data from a subset of PD-1 refractory melanoma patients enrolled in the expanded Phase 2 ENCORE 601 cohort (n = 34) at the ASCO (Free ASCO Whitepaper) Annual Meeting in June. Updated results from the full cohort (n = 55) are expected by the end of this year, at which time the Company will make a decision on registration plans for entinostat in this indication.

Enrollment in the expanded stage 1 ENCORE 601 cohort of patients with microsatellite stable colorectal cancer (MSS-CRC, n = 37) is expected to complete in the third quarter. A decision on whether to continue to the second stage of this cohort is expected in the first half of 2019.

Target enrollment in both the Phase 2 portion of ENCORE 602, the Phase 1b/2 clinical trial evaluating the combination of entinostat plus Genentech’s PD-L1 inhibitor, atezolizumab (TECENTRIQ), in patients with triple negative breast cancer, and the Phase 2 portion of ENCORE 603, evaluating entinostat in combination with Pfizer/Merck KGaA’s PD-L1 inhibitor, avelumab (BAVENCIO), in patients with ovarian cancer, is complete. Topline results from each study are anticipated in the first half of 2019.

ENCORE 606, the Phase 1b/2 trial evaluating entinostat in combination with NKTR-214, Nektar’s CD122-biased agonist, is expected to begin enrolling patients in the first half of 2019.

Dosing of patients with solid tumors in the Phase 1/1b trial evaluating the safety of SNDX-6352 continues as planned. Testing of SNDX-6352 in combination with durvalumab (IMFINZI), AstraZeneca’s human monoclonal antibody directed against PD-L1, was recently initiated, and dosing of patients with SNDX-6352 as a monotherapy is ongoing. The Company anticipates identifying the recommended Phase 2 dose and schedule for SNDX-6352 monotherapy and in combination with durvalumab in the first half of 2019.

The Company expects to commence enrollment in a Phase 1 dose escalation trial of SNDX-6352 in patients with cGVHD by the end of the year. The objectives of this trial are to evaluate the safety and preliminary efficacy of SNDX-6352 in cGVHD and to identify a recommended Phase 2 dose and schedule. Initial results are anticipated in the second half of 2019.

Development of the Company’s portfolio of Menin-Mixed Lineage Leukemia (MLLr) inhibitors is ongoing. The Company continues to expect clinical trials to initiate in the first half of 2019.
Second Quarter 2018 Financial Results

As of June 30, 2018, Syndax had cash, cash equivalents and short-term investments of $98.4 million and 22,705,794 shares issued and outstanding.

On June 18, 2018, the Company signed an exchange agreement with Biotechnology Value Fund and certain affiliated funds ("BVF") under which BVF exchanged 2,000,000 shares of common stock for 2,000,000 Warrant Shares. BVF can exercise the Warrant Shares at an exercise price per share equal to $0.0001 per share. The warrant is issued for a period of 20 years.

In the third quarter of 2018, through August 6th, the Company sold 633,231 shares of its common stock with net proceeds of approximately $4.4 million pursuant to its at-the-market arrangement.

Second quarter 2018 research and development expenses increased to $14.9 million from $9.9 million for the comparable period in the prior year. The increases were primarily due to increased activities in manufacturing for SNDX-6352, increased development activities for the Menin-MLLr and ENCORE 602 programs partially offset by completion of pharmacology trials and lower program cost for E2112. Employee compensation increased due to increased headcount.

General and administrative expenses totaled $4.5 million during the second quarter of 2018, compared to $4.3 million for the comparable period in the prior year. The increase in general and administrative expenses was primarily due to increased pre-commercialization activities and increased patent related legal expenses.

For the three months ended June 30, 2018, Syndax reported a net loss attributable to common stockholders of $18.4 million or $0.74 per share compared to $13.6 million or $0.70 per share for the comparable prior year period.
