Stainwei Granted US Patent for anti-VEGF Monoclonal Antibody and its anti-PD-1 mAb demonstrating prolonged anti-tumor activity in pre-clinical studies

On May 3, 2017 Stainwei Biotech, Inc. (Stainwei), a Chinese biotech company located in Biobay industrial park in Suzhou, China, reported that it has received a patent certificate (Patent No. US9,580,498) issued by the United States Patent and Trademark Office (USPTO) for its novel humanized anti-VEGF monoclonal antibody (mAb code name: hPV19) (Press release, Suzhou Stainwei Biotech, APR 27, 2018, View Source [SID1234525751]). This patent was issued through a pathway of PCT application (PCT/CN2013/086542) filed by Stainwei in 2013. Prior to receiving the US patent, Stainwei has already received two patent certificates for this antibody from China Intellectual Property Office in 2015 and 2016. Stainwei is dedicated to innovation and development of novel therapeutic antibody drugs targeting cancers, age-related macular degeneration (AMD) and immune-related diseases.

A phase I clinical trial evaluating the safety and efficacy of hPV19 in cancer patients is ongoing in China. According to the data released by the company, hPV19 has a unique antigen recognition site (epitope), composed of amino acid sequences different from other commercially available antibodies targeting the same antigen. In both in-vitro and in-vivo experiments, hPV19 showed a 6-8 times higher biological activity than Avastin (generic name: bevacizumab, Roche/Genentech’s anti-VEGF mAb, the world’s first and so far still the only FDA-approved anti-VEGF mAb drug on the market). "In pre-clinical animal studies and early stage clinical trials in cancer patients, hPV19 has also demonstrated an excellent safety and tolerance profile," said Dr. Qunmin Zhou, the company’s co-founder. "We are excited to test its efficacy in the ongoing clinical trials. We are also excited to hopefully bring to the market a unique, non-biosimilar, and stronger therapeutic agent that can benefit our patients."

Meanwhile, Stainwei has filed a PCT patent application for a new formulation of hPV19 mAb intended for the treatment of age-related macular degeneration (AMD), diabetic macular edema (DME) and other eye-disorders associated with VEGF-mediated vascular over-growth. Stainwei has completed preclinical experiments and an application for Investigational New Drug (IND) in AMD and DME will be submitted to China-FDA soon.

The company’s another promising product is a novel anti-PD-1 monoclonal antibody named hAb21 (humanized IgG4-kappa version). hAb21 binds to human PD-1 antigen at a unique site (epitope), which is different from that of Keytruda (Merck) and Opdivo (Bristol-Myers Squibb). hAb21 has shown a remarkable anti-tumor activity in human PD-1 gene knock-in mouse models.

Figure: Effect of hAb21 mAb on tumor growth in knock-in mice expressing human PD-1 (Human PD-1 gene knock-in mice were inoculated with 1×106 syngeneic MC38 tumor cells. When tumors reached 50 mm3 in size,mice were randomized into 3 groups. Intra-peritoneal (i.p) injections with 200 ug mAb (pembrolizumab or hAb21) or saline were given on days 6, 10, 13 and 17 after inoculation. A: Tumor growth in early-stage; B: Tumor growth in both early- and later-stage).

As illustrated in the above figure, syngenic MC38 tumors implanted in the PD-1 gene knock-in mice were completely rejected within 7-10 days without re-growth thereafter in all 6 mice in the group treated with hAb21. Furthermore, repeated MC38 tumor inoculation was performed to those mice on day 30, and tumors were again completely rejected within 10-14 days without further hAb21 treatment. All 6 mice survived to day 60 and received MC38 inoculation for the third time (experiment on-going). In the same knock-in mice treated with Keytruda (pembrolizumab), complete tumor rejection was observed in only 1 out of 6 mice, while initial tumor regression followed by re-growth after the completion of Keytruda treatment were found in the other 5 mice, which all died of tumor progression.

Based on these encouraging results, Stainwei has filed a patent application for hAb21, and is currently carrying out IND-enabling studies. An IND indication for advanced solid tumors is expected to be submitted to China-FDA and US-FDA in the second-half of 2017.

"The first quarter of 2018 marked several significant milestones across our business," said Clay Siegall, Ph.D., President and Chief Executive Officer of Seattle Genetics. "We delivered record ADCETRIS sales that were up 36 percent from the first quarter of 2017, received FDA approval for ADCETRIS in frontline advanced Hodgkin lymphoma, completed the acquisition of Cascadian Therapeutics and were granted FDA Breakthrough Therapy Designation for our late-stage program enfortumab vedotin in metastatic urothelial cancer. Looking ahead, we are on track to achieve several additional milestones this year, which include reporting data from our phase 3 ECHELON-2 trial of ADCETRIS, completing enrollment of urothelial cancer patients who have received both a platinum-based therapy and a CPI in the pivotal trial of enfortumab vedotin, and initiating a pivotal trial of tisotumab vedotin in cervical cancer. We are striving to build a global oncology company with multiple transformative therapies, and we believe our recent progress illustrates our dedication to making a meaningful difference in patients’ lives."

ADCETRIS Program Activities

Label Expansion in Frontline Hodgkin Lymphoma: The U.S. Food and Drug Administration (FDA) approved ADCETRIS in combination with chemotherapy in adult patients with previously untreated Stage III or IV classical Hodgkin lymphoma. The approval is based on the successful outcome of the phase 3 ECHELON-1 clinical trial. In addition, data from the ECHELON-1 trial converted the U.S. accelerated approval of ADCETRIS for the treatment of adults with systemic anaplastic large cell lymphoma (sALCL) after failure of at least one multi-agent chemotherapy regimen to regular approval.
ECHELON-2 Phase 3 Trial: Data are expected in 2018 from the ECHELON-2 phase 3 trial in frontline CD30-expressing peripheral T-cell lymphoma (PTCL), also known as mature T-cell lymphoma (MTCL). Approximately 4,000 people are diagnosed annually with CD30-expressing PTCL.
ADCETRIS is not currently approved for use in frontline PTCL.

Enfortumab Vedotin (EV) Program Activities

Breakthrough Therapy Designation Granted: The FDA granted Breakthrough Therapy Designation to EV for patients with locally advanced or metastatic urothelial cancer who were previously treated with checkpoint inhibitors (CPI) based on data from a phase 1 trial.
EV-201 Pivotal Trial Enrollment Update: By the end of the third quarter of 2018, Seattle Genetics and Astellas expect to complete enrollment in the ongoing EV-201 pivotal trial of patients with locally advanced or metastatic urothelial cancer who previously received both a platinum-based chemotherapy and a CPI therapy. Positive data in this subgroup could serve as the basis for a Biologics License Application (BLA) submission under the FDA’s accelerated approval regulations. In addition, the companies plan to continue enrollment in EV-201 for patients who previously received a CPI but not a platinum agent. The additional data could potentially serve as the basis for a second labeled indication.
EV-301 Phase 3 Trial Planned: Seattle Genetics and Astellas plan to initiate in 2018 a phase 3 trial called EV-301 in patients with metastatic urothelial cancer who received prior CPI. The phase 3 trial is intended to support global regulatory submissions for approval and serve as a confirmatory trial in the United States to support conversion of a potential accelerated approval to regular approval.
Tucatinib Program Activities

Cascadian Therapeutics Acquisition Complete: In March 2018, Seattle Genetics completed its acquisition of Cascadian Therapeutics for $10.00 per share in cash, or approximately $614 million. The most advanced program in the Cascadian pipeline is tucatinib, an oral tyrosine kinase inhibitor that is highly selective for HER2.
HER2CLIMB Pivotal Trial: Enrollment is ongoing in the tucatinib HER2CLIMB trial, a global randomized pivotal trial for patients with HER2-positive (HER2+) metastatic breast cancer, including patients with or without brain metastases. The HER2CLIMB trial is expected to be fully enrolled in 2019.
Tisotumab Vedotin (TV) Program Activities

Planned Pivotal Trial Initiation: Seattle Genetics and Genmab plan to advance TV into a pivotal phase 2 trial for recurrent or metastatic cervical cancer that relapses or progresses after standard of care treatment for cervical cancer. The single-arm trial is designed to enroll approximately 100 women and could potentially support registration under the FDA’s accelerated approval regulations. The trial is expected to begin in the first half of 2018.
Expanding Clinical Development Program: Seattle Genetics and Genmab plan to initiate in 2018 a phase 2 trial of TV as part of a combination regimen in women with first-line metastatic cervical cancer. In addition, a phase 2 trial is expected to begin in 2018 to evaluate TV monotherapy in a range of other solid tumors.
Other Recent Activities

Initiated Ladiratuzumab Vedotin (LV) Combination Trial: The first patient was treated in a phase 1b/2 clinical trial of LV in combination with the CPI pembrolizumab for first-line metastatic triple negative breast cancer. The trial is part of a broad clinical development program evaluating LV both as monotherapy and in combination regimens.
Initiated SGN-CD48A Trial: The first patient was dosed in a phase 1 clinical trial of SGN-CD48A for patients with relapsed or refractory multiple myeloma. SGN-CD48A is an investigational antibody-drug conjugate (ADC) targeted to CD48 that employs the company’s latest ADC technology.
Pipeline Updates: Based on portfolio and resource prioritization, Seattle Genetics is no longer planning to develop denintuzumab mafodotin and its clinical-stage PBD-based ADC programs.
AACR Presence: Data from multiple research and early clinical abstracts were presented at the 2018 American Association for Cancer Research (AACR) (Free AACR Whitepaper) annual meeting. These data presentations illustrated the company’s novel antibody and ADC technologies, rationale for combining ADCs with CPIs, and its proprietary immuno-oncology programs. Additionally, Seattle Genetics reported preclinical data describing novel empowered antibody SEA-BCMA for multiple myeloma, which is expected to enter a phase 1 clinical trial during 2018.
ADC Collaborator Milestone: Seattle Genetics achieved a milestone payment under its ongoing collaboration with AbbVie triggered by a phase 2 trial initiation of an ADC for cancer. As of March 31, 2018, the company had generated approximately $400 million from its ADC collaborations, primarily from upfront and milestone payments.
Pieris Collaboration: Seattle Genetics entered into a collaboration and license agreement with Pieris Pharmaceuticals to develop targeted bispecific immuno-oncology treatments.
PharmaMar Collaboration: Seattle Genetics licensed exclusive worldwide rights to certain PharmaMar molecules for use in the development of ADCs.
First Quarter 2018 Financial Results

Total revenues in the first quarter ended March 31, 2018 increased to $140.6 million, compared to $109.1 million for the same period in 2017. Revenues in the first quarter of 2018 included:

ADCETRIS net sales of $95.4 million, a 36 percent increase from net sales of $70.3 million in the first quarter of 2017.
Royalty revenues of $15.7 million, compared to $17.0 million in the first quarter of 2017. Royalty revenues are primarily driven by international sales of ADCETRIS by Takeda. The decrease was a result of the company adopting the new accounting standards for revenue recognition.
Amounts earned under the company’s ADCETRIS and ADC collaborations totaling $29.6 million, compared to $21.8 million in the first quarter of 2017.
Total costs and expenses for the first quarter of 2018 were $234.4 million, compared to $168.4 million for the first quarter of 2017. Costs and expenses in the first quarter of 2018 included:

Research and development expenses of $152.5 million, compared to $118.2 million for the same period in 2017. The increase in 2018 reflects tucatinib development activities and $35.0 million in upfront costs related to technology licensing with Pieris and PharmaMar. In addition, 2018 expenses reflect increased activities for tisotumab vedotin, ladiratuzumab vedotin and the company’s pipeline programs.
Selling, general and administrative expenses of $66.2 million, compared to $38.4 million for the same period in 2017. The increase reflects transaction costs associated with the acquisition of Cascadian Therapeutics and increased commercial costs to support the launch of ADCETRIS in frontline Hodgkin lymphoma.
Non-cash, share-based compensation cost for the first quarter of 2018 was $16.8 million, compared to $14.5 million for the first quarter of 2017.

Net loss for the first quarter of 2018 was $111.7 million, or $0.73 per share, compared to a net loss of $60.0 million, or $0.42 per share, for the first quarter of 2017. Net loss for the quarter includes a non-cash charge of $18.8 million associated with Seattle Genetics’ common stock holdings in Immunomedics and Unum Therapeutics.

As of March 31, 2018, Seattle Genetics had $399.9 million in cash and investments, excluding its Immunomedics and Unum common stock investments, which were valued at $179.5 million. The cash and investments balance reflects net proceeds of $658.2 million from the company’s equity financing completed in February 2018, which was primarily used to fund the March 2018 acquisition of Cascadian Therapeutics for approximately $614.1 million.

2018 Financial Outlook

As a result of the recent approval of ADCETRIS in combination with chemotherapy in adult patients with previously untreated Stage III or IV classical Hodgkin lymphoma, the company’s full year 2018 ADCETRIS sales guidance provided in February 2018 no longer reflects management’s expectations and is being withdrawn. For the second quarter of 2018, Seattle Genetics expects sales of ADCETRIS will be in the range of $105 million to $110 million.

As a result of expenses totaling approximately $50 million in the first quarter of 2018 related to the acquisition of Cascadian and upfront technology in-licensing costs, as well as additional forecasted operating costs attributed to the tucatinib program, the company increased its expectations for 2018 operating expenses and other costs as follows:

A Phase 3 study evaluating lumacaftor/ivacaftor in children with CF ages 12 to <24 months is planned to start in the second half of 2018.

TRIPLE COMBINATION REGIMENS
Phase 3 program of VX-659 and VX-445 underway: In a separate press release today, Vertex announced that it is initiating two Phase 3 studies to evaluate VX-445, tezacaftor and ivacaftor as an investigational triple combination regimen for people with CF ages 12 and older. The first Phase 3 study will evaluate approximately 360 people with CF who have one copy of the F508del mutation and one minimal function mutation. The second Phase 3 study will evaluate approximately 100 people with CF who have two copies of the F508del mutation and is supported by Phase 2 data that were reported today.

In addition, Vertex announced today that the first patients have been dosed in the Phase 3 study evaluating the investigational triple combination regimen VX-659, tezacaftor and ivacaftor for use in people with CF ages 12 and older who have one F508del mutation and one minimal function mutation. Enrollment is ongoing.

SICKLE CELL DISEASE & β-THALASSEMIA
Planned initiation of Phase 1/2 trial of CTX001 in β-thalassemia in 2018: CRISPR Therapeutics, together with Vertex, has filed clinical trial applications (CTAs) in various European countries to conduct a Phase 1/2 trial of CTX001, an autologous gene-edited hematopoietic stem cell therapy for

4

patients suffering from β-thalassemia. Approval for the first of these CTAs has been received, and clinical trials are expected to begin in Europe in 2018. The Phase 1/2 trial of CTX001 is designed to assess the safety and efficacy in adult transfusion-dependent β-thalassemia patients. Additionally, the companies plan to submit an Investigational New Drug (IND) Application for CTX001 in sickle cell disease in the U.S. in the first half of 2018.

PAIN
Phase 2 study of VX-150 shows significant relief of acute pain: During the first quarter, Vertex announced positive data from a Phase 2 proof-of-concept study evaluating VX-150, a selective NaV1.8 channel inhibitor, for the treatment of acute pain following bunionectomy surgery. This Phase 2 study was the second positive proof-of-concept study for VX-150. A third Phase 2 study of VX-150 is currently ongoing in neuropathic pain with data expected in early 2019. Vertex also recently initiated a Phase 1 study of a second NaV1.8 inhibitor, VX-128, in healthy volunteers.

Non-GAAP Financial Measures
In this press release, Vertex’s financial results and financial guidance are provided in accordance with accounting principles generally accepted in the United States (GAAP) and using certain non-GAAP financial measures. In particular, non-GAAP financial results and guidance exclude (i) stock-based compensation expense, (ii) revenues and expenses related to business development transactions including collaboration agreements, asset acquisitions and consolidated variable interest entities, (iii) non-operating tax adjustments and (iv) other adjustments, including gains or losses related to the fair value of the company’s strategic investments in CRISPR and Moderna Therapeutics, Inc. These results are provided as a complement to results provided in accordance with GAAP because management believes these non-GAAP financial measures help indicate underlying trends in the company’s business, are important in comparing current results with prior period results and provide additional information regarding the company’s financial position. Management also uses these non-GAAP financial measures to establish budgets and operational goals that are communicated internally and externally and to manage the company’s business and to evaluate its performance.

Note 1: In the three months ended March 31, 2017, collaborative revenues were primarily attributable to a $230.0 million upfront payment earned from our collaboration with Merck KGaA, Darmstadt, Germany.
Note 2: The company recorded a gain of $92.5 million to "Other income (expense), net" in the three months ended March 31, 2018 related to an increase in fair value of our investment in CRISPR Therapeutics AG. The company adopted ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities effective January 1, 2018. Prior to the adoption of ASU 2016-01 on January 1, 2018, changes in the fair value of our investment in CRISPR were recorded to equity on the company’s consolidated balance sheets until the related gains and losses were realized; therefore, there was no comparable expense in the three months ended March 31, 2017.
Note 3: The company consolidates the financial statements of one of its collaborators as of March 31, 2018 and December 31, 2017. This VIE is consolidated because Vertex has licensed the rights to develop the collaborator’s most significant intellectual property asset. Each reporting period Vertex estimates the fair value of the contingent payments by Vertex to this collaborator. Any increase in the fair value of these contingent payments results in a decrease in net income attributable to Vertex (or an increase in net loss attributable to Vertex) on a dollar-for-dollar basis. The fair value of contingent payments is evaluated each quarter and any change in the fair value is reflected in the company’s statement of operations.
Note 4: In the three months ended March 31, 2018 and 2017, "Collaborative and transaction revenue and expenses" primarily consisted of (i) revenues and operating costs and expenses attributable to the company’s VIEs, (ii) changes in the fair value of contingent payments due to VIEs, and (iii) collaboration revenues and payments including those related to the company’s oncology collaboration with Merck KGaA, Darmstadt, Germany. In the three months ended March 31, 2018 "Collaborative and transaction revenue and expenses" included a $24.0 million increase in the fair value of contingent milestone payments and royalties payable by Vertex to BioAxone that was attributable to Vertex. In the three months ended March 31, 2017, "Collaborative and transaction revenue and expenses" included the $230.0 million upfront payment earned from Merck KGaA discussed in Note 1.
Note 5: In the three months ended March 31, 2018, "Other adjustments" primarily consisted of the increase in fair value of the company’s investment in CRISPR Therapeutics AG discussed in Note 2 above as well as a $2.9 million increase in the fair value of our investment in Moderna Therapeutics, Inc. In the three months ended March 31, 2017, "Other adjustments" primarily consisted of restructuring charges related to the company’s decision to consolidate its research activities into its Boston, Milton Park and San Diego locations and to close our research site in Canada.
Note 6: In the three months ended March 31, 2018, "Non-operating tax adjustments" consisted of excess tax benefits related to stock-based compensation. On a GAAP basis, the company recorded an excess tax benefit from income taxes related to stock-based compensation of $21.9 million in the first quarter of 2018 and expects to record excess tax benefits from incomes taxes of a similar nature in the second and third quarter of the 2018. In the fourth quarter of 2018, the company expects to record on a GAAP basis a provision for taxes related to stock-based compensation equal to the cumulative benefits recorded through the first three quarters of 2018. As a result, these excess tax benefits and provisions recorded on a quarterly basis are not expected to have any effect on the company’s GAAP annual provision for (benefit from) income taxes. Accordingly, in the first three quarters of 2018, the Company is excluding the excess tax benefits and in the fourth quarter of 2018 will exclude the provision for taxes from its Non-GAAP measures.
Note 7: In the three months ended March 31, 2018 and 2017, "Cost of sales" included $0.8 million and $0.5 million, respectively, in stock-based compensation expense. Beginning with the first quarter of 2018, the company is adjusting for the stock-based compensation expense recorded in "Cost of Sales" in its

11

reconciliation of "Non-GAAP net income attributable to Vertex" and "Non-GAAP cost of sales". In its Non-GAAP reconciliation, the company is not adjusting for the stock-based compensation expense recorded in "Cost of Sales" for the first quarter of 2017.
