"This more detailed publication was consistent with or improved from the summary results presented at ESMO (Free ESMO Whitepaper) last fall," said Mike Sherman, president and CEO of Endocyte. "The response rates demonstrated to date are encouraging, especially since no agent has been proven to improve survival in this heavily pre-treated patient population. We look forward to beginning enrollment in our global phase 3 VISION trial of 177Lu-PSMA-617 this quarter."

Mr. Sherman continued, "We also look forward to Professor Hofman presenting additional updates at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting in June, with new data from the trial’s expansion to 50 patients. Given the expected immaturity of survival data in the additional 20 patients, our focus will be on the PSA and RECIST response rates."

Updated Data Disclosed in The Lancet Oncology

The journal article published today in The Lancet Oncology reviews the design and results to date of the original 30 patients from this phase 2 trial. This publication provides a more comprehensive summary than previously disclosed of patient characteristics, treatment regimen and more mature outcome data, including updated Kaplan-Meier curves estimating overall survival and PSA progression-free survival (PFS) as well as a swimmer’s plot of the 30 patients.

This study evaluated a heavily pre-treated patient population, 87% of which had received > 1 line of prior chemotherapy (80% docetaxel and 47% cabazitaxel) and 83% received prior abiraterone acetate and/or enzalutamide.

Observations in this study include a PSA reduction of at least 50% from baseline (PSA50) in 57% of patients, a PSA reduction of at least 80% from baseline (PSA80) in 43% of patients and a PSA reduction of > 96% in 20% of patients who were identified as ‘exceptional responders’. Regarding disease progression and survival, a median PSA PFS of 7.6 months and a median overall survival (OS) of 13.5 months were observed. Both the median PSA PFS and the median OS reflect improved outcomes versus the 6.3 months and 12.7 months for each endpoint, respectively, previously presented at the 2017 ESMO (Free ESMO Whitepaper) Congress.

Notably, patients with a PSA50 response had median PSA PFS of 9.9 months and median OS of 17.0 months compared to PSA PFS of 4.1 months and median OS of 9.9 months for those who did not achieve a PSA50 response. Additionally, clinically meaningful improvements in quality of life measures were observed.

17 patients (57%) had prostate cancer working group 2 (PCWG2) RECIST 1.1 evaluable nodal or visceral target lesions following CT scan at baseline. Confirmed objective responses were seen in 14 (82%) of these 17 patients, including complete and partial response rates of 29% and 53%, respectively. This response rate is greater than the 71% PCWG2 RECIST 1.1 objective response rate previously reported.

177Lu-PSMA-617 was well tolerated, with no significant dose-limiting toxicities observed. The most common treatment-related toxicity was Grade 1 xerostomia (dry mouth) seen in 87% of patients, which is higher than previously reported (63%), but generally didn’t require any intervention. The occurrence of treatment-related Grade 3-4 hematologic toxicity was low and comparable to the largest retrospective published cohort.1

"Positive momentum continues to build throughout our product pipeline," said Thomas J. Schall, Ph.D., President and Chief Executive Officer of ChemoCentryx. "A major goal is on the near horizon: the completion of patient enrollment in our global Phase III ADVOCATE pivotal trial of avacopan for the treatment of ANCA-associated vasculitis, while a second trial of avacopan in the orphan kidney disease of C3G is well underway. Standing also on the threshold of a new value-creating era, we intend to expand avacopan’s scope into orphan dermatological disease with the launch of clinical trials in HS in 2018. Advances continue with our CCR2 inhibitor CCX140, with trials launched in primary FSGS, a devastating disease with no approved therapies. With such progress continuing, we are laying the foundation for commercialization of these novel therapies in the U.S. in order to bring the benefits of our precision medicines to those enduring these serious diseases."

Recent Highlights

Patient enrollment in ChemoCentryx’s Phase III ADVOCATE pivotal trial of avacopan for the treatment of ANCA-associated vasculitis is nearing completion with over 85% of the 300 patient target enrolled to date. The trial will evaluate the safety and efficacy of avacopan following 52 weeks of treatment. The ADVOCATE trial is designed to show the effect of avacopan on improving active vasculitis, as well as testing durable clinical benefit, which is one of the major limitations of the current standard of care. The Company’s CMA application for avacopan for the treatment of ANCA-associated vasculitis is currently under review by the EMA.

ChemoCentryx has reached approximately 30% of the patient enrollment target in its clinical trial evaluating avacopan for C3G. C3G is a rare disorder that often affects the young, requiring dialysis and often kidney transplant with relapsing disease common. There is no approved effective treatment.

In 2018, ChemoCentryx plans to launch clinical trials of avacopan in HS, an inflammatory and chronic skin disease characterized by recurrent, painful, boil-like nodules under the skin.

The Company’s CCR2 inhibitor CCX140 is currently being studied in two sub-populations of primary FSGS, an orphan kidney disease with no approved treatment option. One trial involves sub-nephrotic primary FSGS patients, whose disease cause is idiopathic; and the other trial is for primary FSGS patients with nephrotic syndrome, where reduction in proteinuria may constitute the registration endpoint. Further support of CCR2’s role in FSGS is highlighted in the peer reviewed findings published in March in the journal PLOS-ONE.
First Quarter 2018 Financial Results

Cash, cash equivalents and investments totaled $177.1 million at March 31, 2018.

Revenue was $9.5 million for the first quarter of 2018, compared to $8.2 million for the same period in 2017. Revenue recognized represents amortization of the upfront license fee commitments, milestone payments and collaboration funding from Vifor pursuant to the Avacopan Agreement, Avacopan Amendment and CCX140 Agreement. The increase from 2017 to 2018 was primarily due to the Company’s adoption of Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers effective January 1, 2018.

Research and development expenses were $14.7 million for the first quarter of 2018, compared to $10.0 million for the same period in 2017. The increase from 2017 to 2018 was primarily due to continued patient enrollment of the avacopan Phase III ADVOCATE pivotal trial in patients with ANCA-associated vasculitis and start-up expenses related to the CCX140 and avacopan Phase II clinical trials in patients with FSGS and C3G, respectively.

General and administrative expenses were $4.7 million for the first quarter of 2018, compared to $4.6 million for the same period in 2017. The increase from 2017 to 2018 was primarily due to higher employee-related expenses partially offset by a decrease in professional legal fees.

Net loss for the first quarter of 2018 was $9.4 million, compared to $6.0 million for the same period in 2017.

Total shares outstanding at March 31, 2018 were approximately 49.1 million shares.

The Company expects to utilize cash and investments between $65 million and $75 million for the twelve months ending December 31, 2018.

"Rhabdomyosarcoma is the most common type of tissue sarcoma in children. While initial response to treatment is generally favorable, there is an important need for new treatments, especially in children who experience relapse." said John Friend, M.D., chief medical officer of Cellectar. "Cellectar is committed to working closely with the FDA to fully evaluate the potential for targeted delivery of CLR 131 to address this currently unmet medical need."

Orphan drug designation provides seven-year market exclusivity, increased engagement and assistance from the FDA, tax credits for certain research, research grants and a waiver of the New Drug Application user fee. Rhabdomyosarcoma is recognized by the FDA as an orphan disease, usually defined as a condition that affects fewer than 200,000 people nationwide.

About Rhabdomyosarcoma

Rhabdomyosarcoma (RMS), a malignant tumor of mesenchymal origin, is the most common soft tissue sarcoma in children, accounting for approximately 40% of childhood soft tissue sarcomas in the United States. The incidence is about 4.5 cases per 1 million per year in children younger than 15 years and more than 50% are younger than 10 years at diagnosis. Approximately 340 new cases are diagnosed each year in North America and the prognosis is favorable with a 64% 5-year survival in children aged birth to 19 years [Ward 2014]. At least one-third of all patients will experience disease progression or relapse, and 95% of all failures occur within 3 years. The median progression free survival following the first recurrence or progression is approximately nine months.

About CLR 131

CLR 131 is Cellectar’s investigational radioiodinated PDC therapy that exploits the tumor-targeting properties of the company’s proprietary phospholipid ether (PLE) and PLE analogs to selectively deliver radiation to malignant tumor cells, thus minimizing radiation exposure to normal tissues. CLR 131, is in a Phase 2 clinical study in relapsed or refractory (R/R) MM and a range of B-cell malignancies and a Phase 1 clinical study in patients with (R/R) MM exploring fractionated dosing. In 2018 the company plans to initiate a Phase 1 study with CLR 131 in pediatric solid tumors and lymphoma, and a second Phase 1 study in combination with external beam radiation for head and neck cancer.

On May 9, 2018 BioSpecifics Technologies Corp.

"We are enthusiastic about the sustained year-over-year revenue growth of our CCH product, XIAFLEX, in its marketed indications, Dupuytren’s Contracture and Peyronie’s Disease, and by the potential progress of the broader CCH development pipeline. During the first quarter of 2018, XIAFLEX became commercially available in Canada for Peyronie’s Disease and our partner Endo reported updated data from the Phase 2b clinical trial of CCH for the treatment of cellulite at the American Society for Aesthetic Plastic Surgery," said Thomas L. Wegman, President of BioSpecifics. "We also remain focused on identifying and developing CCH for medically necessary indications, and we remain on track to report preliminary data later this year for our ongoing Phase 1 clinical trial in uterine fibroids, a painful condition of the reproductive tract in which benign tumors contain large amounts of collagen and we are excited by the potential of CCH to alleviate patients’ symptoms and ultimately avoid invasive surgery."

First Quarter 2018 Financial Results

BioSpecifics reported net income of $4.0 million for the first quarter ended March 31, 2018, or $0.55 per basic share and $0.54 per share on a fully diluted basis, compared to net income of $3.3 million, or $0.47 per basic share and $0.46 per share on a fully diluted basis, for the same period in 2017.

The Company adopted Accounting Standard Codification (ASC) 606, Revenue from Contracts with Customers, as of January 1, 2018, applying the modified-retrospective method, changed the timing of its recognition of royalty and mark-up on cost of goods sold revenue. Beginning in 2018, BioSpecifics recorded these royalty revenues based on estimates of the net sales and mark-up on cost of goods sold that occurred during the relevant period thereby eliminating the previously utilized one quarter lag. Previously, these amounts were not recognized until they were fixed and determinable. In addition, deferred revenue associated with the pre-payment of foreign mark-up on cost of goods sold revenue will no longer be recognized over time based on sales by non-affiliated sub-licensees of Endo outside of the U.S. and, under ASC 606, would have been recognized when the Company amended its License Agreement in 2016. Prior period amounts have not been adjusted and the Company recognized a cumulative-effect adjustment to retained earnings on January 1, 2018 of $10.3 million.

Total revenue for the first quarter ended March 31, 2018 was $7.1 million, compared to $7.7 million for the same period in 2017. The decrease in total revenues for the quarterly period was primarily due to lower mark-up on cost of goods sold revenue in the U.S and prepaid foreign mark-up on cost of goods sold revenue recognized under new revenue standard ASC 606, as of January 1, 2018, which was partially offset by an increase in royalties associated with slightly higher overall net sales of XIAFLEX.

Licensing revenue consists of licensing fees, sublicensing fees and milestones. BioSpecifics recognized licensing revenue for the first quarter ended March 31, 2018 and 2017 of approximately $4,409 in each period.

Research and development (R&D) expenses for the first quarter ended March 31, 2018 were $0.2 million compared to $0.3 million for the same period in 2017.

General and administrative expenses for the first quarter ended March 31, 2018 were $2.1 million, compared to $2.4 million for the same period in 2017.

Provision for income taxes for the first quarter ended March 31, 2017 were $1.1 million, compared to $1.8 million for the same period in 2017.

As of March 31, 2018, BioSpecifics had cash and cash equivalents and investments of $64.2 million, compared to $65.1 million as of December 31, 2017. The Company’s cash and cash equivalents and investments were slightly lower due to the timing of Endo’s payment of its quarterly XIAFLEX royalties, which was received in April 2018.

CCH Pipeline Updates and Anticipated Upcoming Milestones

BioSpecifics manages the development of collagenase clostridium histolyticum (CCH) for the treatment of uterine fibroids and has the right to initiate the development of any new potential indication not licensed by Endo. Endo’s licensed indications include Dupuytren’s Contracture and Peyronie’s Disease, both approved and marketed; in addition to cellulite, adhesive capsulitis, human and canine lipoma, lateral hip fat and plantar fibromatosis.

In April 2018, Endo presented clinical data from the Phase 2b study of CCH for the treatment of cellulite during the Premier Global Hot Topics session at the annual meeting of the American Society for Aesthetic Plastic Surgery (ASAPS). A statistically significant proportion of CCH subjects reported being "Satisfied" or "Very Satisfied" with their cellulite treatment compared to placebo subjects. CCH was also well-tolerated by all dose groups. Most adverse events (AEs) were mild to moderate and primarily limited to the local injection area such as injection site bruising (approximately 75 percent) and injection site pain (approximately 59 percent) with 92 percent of all related AEs were mild to moderate in the CCH group compared to 96 percent in the placebo group.
In April 2018, Paladin Labs, a subsidiary of Endo, announced the commercial availability of XIAFLEX in Canada for the treatment of Peyronie’s Disease.
In February 2018, Endo initiated two Phase 3 clinical trials of CCH for the treatment of cellulite. Top-line results are expected in the first quarter of 2019.
BioSpecifics is conducting an ongoing Phase 1 clinical trial of CCH for the treatment of uterine fibroids with data expected later this year. This Phase 1 open-label dose escalation study is being conducted at the Department of Gynecology & Obstetrics at Johns Hopkins University and is designed to enroll 15 female subjects treated prior to hysterectomy. The trial will assess the safety and tolerability of a single injection of CCH directly into the uterine fibroid under transvaginal ultrasound guidance. The secondary endpoints will assess symptoms of pain and bleeding, quality of life throughout the study in addition to size, collagen content and rate of apoptosis of CCH treated fibroids.
