"This past quarter, we began an important new period for CRISPR Therapeutics with the treatment of the first patient in our clinical trial for CTX001 in hemoglobinopathies," said Samarth Kulkarni, Ph.D., Chief Executive Officer of CRISPR Therapeutics. "This is a significant landmark for the Company and we continue to enroll patients in our trials for both beta thalassemia and sickle cell disease. With the acceptance of our IND and CTA for CTX110, we look forward to the initiation of our clinical trials for our allogeneic CAR-T programs in the near-term and hope to bring other CAR-T programs to the clinic in the next six to twelve months."

Recent Highlights and Outlook

Hemoglobinopathies

Beta thalassemia
In April 2019, CRISPR Therapeutics and its partner, Vertex, announced that the U.S. Food and Drug Administration (FDA) had granted Fast Track Designation for CTX001, an investigational, autologous, gene-edited hematopoietic stem cell therapy, for the treatment of transfusion-dependent beta thalassemia (TDT). In February 2019, CRISPR and Vertex announced that the first patient had been treated with CTX001 in a Phase 1/2 clinical study of patients with TDT, marking the first company-sponsored use of a CRISPR/Cas9 therapy in a clinical trial. Enrollment in the Phase 1/2 study in patients with TDT is ongoing.

Sickle Cell Disease
The companies are also evaluating CTX001 for the treatment of sickle cell disease (SCD) and received Fast Track Designation for CTX001 from the FDA in January 2019 for SCD. The companies announced in February 2019 that the first patient had been enrolled in a Phase 1/2 clinical study of CTX001 in severe SCD in the U.S. and is expected to be infused with CTX001 in mid-2019. Enrollment in the Phase 1/2 study in patients with SCD is ongoing.
Immuno-Oncology

CTX110
Earlier this year, the FDA approved CRISPR Therapeutics’ Investigational New Drug (IND) application for CTX110, its wholly-owned allogeneic CAR-T cell therapy targeting CD19+ malignancies. Additionally, the Company has obtained approval from Health Canada for its Clinical Trial Application (CTA). CRISPR Therapeutics remains on track to initiate a Phase 1/2 trial to assess the safety and efficacy of CTX110 in the first half of 2019 and continues to work closely with various clinical sites to begin the trial. The Company’s proprietary CRISPR-based allogeneic CAR-Ts have the potential to create the next-generation of cell therapies that may have a superior product profile compared to current autologous therapies and allow accessibility to broader patient populations.

CRISPR Therapeutics continues to advance additional allogeneic CAR-T candidates including: CTX120, targeting B-cell maturation antigen (BCMA) for the treatment of multiple myeloma; and CTX130, targeting CD70 for the treatment of solid tumors and hematologic malignancies. Earlier this month, the Company presented preclinical data targeting multiple solid tumor types with anti-CD70 allogeneic CAR-T cells, further demonstrating consistent expression, durability, selectivity and potent cell killing. The Company also presented data targeting CD33 that showed potent preclinical activity against acute myeloid leukemia (AML) cells. These data were presented during poster sessions at the 2019 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting.

CRISPR Therapeutics will present additional data at the upcoming 2019 American Society of Gene and Cell Therapy (ASGCT) (Free ASGCT Whitepaper) Annual Meeting demonstrating the potential of CRISPR/Cas9 allogeneic CAR-T cell candidates for multiple oncology targets. CRISPR/Cas9 allogeneic CAR-T cells show consistently high percent CAR expression, while maintaining durable potency, low exhaustion, and lack of alloreactivity (#841). The Company will also present data evaluating homology-independent CRISPR/Cas9 off-target assessments methods (#134).
Corporate Development

The U.S. Patent Office issued four patents to Dr. Emmanuelle Charpentier, together with The Regents of the University of California and University of Vienna (collectively, CVC). Additionally, CVC was recently granted its third patent in Europe. These patents expand CVC’s wide-ranging CRISPR-Cas9 gene-editing patent portfolio.

Earlier this year, CRISPR Therapeutics announced strategic collaborations with StrideBio, Inc. and ProBioGen. The Company continues to examine new technologies and capabilities in support of existing programs.

In February, CRISPR Therapeutics proposed to elect John T. Greene and Katherine A. High, M.D. to its Board of Directors at the Company’s upcoming annual general meeting to be held later this year. Together, they will bring significant strategic and operational experience to CRISPR Therapeutics.
First Quarter 2019 Financial Results

Cash Position: Cash as of March 31, 2019, was $437.5 million, compared to $456.6 million as of December 31, 2018, a decrease of $19.1 million. Cash used in operations drove the decrease, offset by $25.7 million in net cash provided by financing activities during the quarter.

Revenues: Total collaboration revenues were $0.3 million for the first quarter of 2019 compared to $1.4 million for first quarter of 2018. CRISPR’s collaboration revenue is attributable to its research partnerships with Casebia and Vertex. Cost sharing on the Vertex co-development and co-promotion agreement related to hemoglobinopathies is not included in revenue, but instead as an offset to expense in R&D.

R&D Expenses: R&D expenses were $33.8 million for the first quarter of 2019 compared to $19.5 million for the first quarter of 2018. The increase was driven by headcount and services expense supporting the advancement of the hemoglobinopathies program, the broadening of the wholly-owned immuno-oncology portfolio, as well as increased investment in the Company’s CRISPR/Cas9 platform research.

G&A Expenses: General and administrative expenses were $14.9 million for the first quarter of 2019 compared to $8.8 million for the first quarter of 2018. The increase was driven by headcount-related expense and external professional and consulting service expense.

Net Loss: Net loss was $48.4 million for the first quarter of 2019 compared to a loss of $28.3 million for the first quarter of 2018, driven predominantly by increased R&D expense in the quarter.

Forbius’ AVID200, a Novel TGF-beta 1 & 3 Inhibitor, Cleared by Health Canada to Commence Phase 1 Clinical Trial in Solid Tumors

On April 29, 2019 Forbius, a clinical-stage company that develops novel biologics for the treatment of cancer and fibrosis, announced that it has received a no objection letter from Health Canada for its clinical trial application (CTA) to conduct a Phase 1 trial in solid tumors with immuno-oncology candidate AVID200, a rationally designed and highly potent inhibitor of TGF-beta 1 & 3 (Press release, Forbius, APR 29, 2019, View Source [SID1234535642]).

AVID200-03 (NCT03834662) is a Phase I, open label, dose-escalation trial to establish the recommended phase 2 dose (RP2D) of AVID200 in patients with advanced or metastatic malignancies. The trial is currently enrolling patients at centers in the U.S. and will now be expanded to additional clinical sites in Canada to recruit a total of up to 36 patients.

TGF-beta 1 & 3 are the main oncogenic TGF-beta isoforms expressed by many solid tumors and represent promising immuno-oncology targets. These TGF-beta isoforms are implicated in T-cell suppression, fibrosis in the tumor microenvironment, and resistance to immunotherapeutics such as nivolumab (Opdivo) and pembrolizumab (Keytruda) (Chakravarthy et al., Nature Comm., 2018; Tauriello et al., Nature, 2018; Mariathasan et al., Nature, 2018).

About AVID200 and the AVID200-03 Trial
AVID200 is an isoform-selective and highly potent inhibitor of TGF-beta 1 & 3 undergoing Phase 1 clinical testing in solid tumors and fibrotic diseases. TGF-beta 1 & 3 are the principal disease-driving isoforms, while TGF-beta 2 is responsible for normal cardiac function and hematopoiesis.

AVID200’s selectivity for TGF-beta 1 & 3 was designed to achieve optimal efficacy while circumventing cardiac and other safety issues that have limited the applicability of older-generation, non-selective TGF-beta inhibitors. Therefore, AVID200 is positioned to be an effective and well-tolerated therapeutic in a variety of clinical settings, including in combination with anti-PD-(L)1 therapy.

AVID200-03 (NCT03834662) is an open label, multicenter, dose-escalation study to evaluate the safety, pharmacokinetics, pharmacodynamics, and antitumor effects of AVID200 in patients with advanced or metastatic solid tumor malignancies.

MorphoSys and I-Mab Biopharma Announce First Patient Dosed in Phase 3 Clinical Study of MOR202/TJ202 in Multiple Myeloma

On April 29, 2019 MorphoSys AG (FSE: MOR; Prime Standard Segment, MDAX & TecDAX; NASDAQ: MOR) and I-Mab Biopharma (I-Mab), a China-based clinical stage biopharmaceutical company exclusively focused on the development of innovative biologics in immuno-oncology and autoimmune diseases, reported that the first patient has been dosed in a phase 3 randomized and multi-center clinical study in Taiwan to evaluate MorphoSys’s investigational human CD38 antibody MOR202/TJ202 in combination with lenalidomide in patients with relapsed or refractory multiple myeloma (Press release, MorphoSys, APR 29, 2019, View Source [SID1234556333]). I-Mab has exclusive rights for development and commercialization of MOR202/TJ202 in China, Taiwan, Hong Kong and Macao.

"The initiation of our first phase 3 trial represents another important milestone in advancing MOR202/TJ202 towards registration with the hope of providing more therapeutic options for multiple myeloma patients globally. With planned enrollment of 291 patients, this will be a broad trial of this second most common blood cancer worldwide," said Dr. Joan Shen, M.D., Head of R&D at I-Mab. "In parallel with our pivotal phase 2 trial of MOR202/TJ202 in combination with dexamethasone, the phase 3 study will further assess the efficacy of MOR202/TJ202 as a potential second line treatment in multiple myeloma."

Under I-Mab’s fast-to-market development strategy, the phase 3 study, if successful, could lead to a biologics license application (BLA) in Greater China. The randomized, open-label, parallel-controlled, multicenter study will be conducted in mainland China and Taiwan to evaluate the efficacy and safety of the combination of MOR202/TJ202 plus lenalidomide (LEN) and dexamethasone (DEX) versus the combination of LEN and DEX in patients with relapsed or refractory multiple myeloma who received at least one prior line of treatment. The primary endpoint is to evaluate the progression-free survival (PFS) comparing the efficacy of MOR202/TJ202 plus LEN/DEX versus LEN/DEX.

The dosing of the first patient triggers a milestone payment of USD 3 million to MorphoSys.

"We are delighted that our partner I-Mab has started a phase 3 trial of MOR202/TJ202 in combination with lenalidomide in Asia in addition to the ongoing phase 2 trial of MOR202 in combination with dexamethasone. We see a high medical need for the treatment of patients with multiple myeloma in the Chinese region and look forward to supporting I-Mab in developing this investigational compound for these patients," said Dr. Malte Peters, Chief Development Officer of MorphoSys AG.

With MorphoSys’s support through a licensing agreement in November 2017, I-Mab is currently leading the clinical development of MOR202/TJ202 in Greater China, including mainland China, Hong Kong, Macao and Taiwan. In addition to Taiwan, I-Mab has filed an investigational new drug (IND) application to China’s National Medical Products Administration in August 2018. Previously on March 20, 2019, MorphoSys and I-Mab announced the first patient dosing of MOR202/TJ202 in a phase 2 multi-center clinical study in Taiwan in patients with relapsed or refractory multiple myeloma.

About MOR202/TJ202
MOR202/TJ202 is an investigational human monoclonal antibody derived from MorphoSys’s HuCAL antibody technology. The antibody is directed against CD38 on the surface of multiple myeloma cells, which has been characterized as one of the most strongly and uniformly expressed antigens on the surface of malignant plasma cells. According to its suggested mode of action, the antibody recruits cells of the body’s immune system to kill the tumor through antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP). The antibody does not involve complement dependent cytotoxicity, or CDC, an additional immune mechanism involved in tumor cell killing. Scientific research suggest that an anti-CD38 antibody may have therapeutic potential also in other cancers as well as autoimmune diseases. Based on an exclusive regional licensing agreement signed in late 2017, I-Mab owns the exclusive rights for development and commercialization of MOR202/TJ202 in China, Taiwan, Hong Kong and Macao.

ONC213 is the fourth molecule in the company’s pipeline of "imipridone" family of anti-cancer small molecules that target G protein-coupled receptors, following ONC201, ONC206 and ONC212. As with other members of the imipridone class, ONC213 has very attractive chemical and biological properties including oral bioavailability, chemical stability and a large therapeutic index.

"We are delighted by the decision of the US Patent Office to grant Composition of Matter to the novel molecule ONC213," said Martin Stogniew, Ph.D., Chief Development Officer of Oncoceutics. "This patent paves the way for future generations of imipridones to enter the clinic and eventually benefit the lives of patients."

ONC213 has demonstrated anti-cancer activity and safety in various preclinical oncology models across hematological malignancies and solid tumors tested in the lab of Principal investigator Dr. Yubin Ge, Associate Professor of Oncology at the Karmanos Cancer Institute and Wayne State University School of Medicine. Results presented at the 61st American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting demonstrated that ONC213 targets leukemic stem cells in patient-derived xenograft mouse models, is well tolerated and combines synergistically with Bcl-2 inhibitor Venetoclax. Dr. Ge recently received a grant from the Kids Without Cancer and the Children’s Hospital of Michigan Foundation to further determine the mechanism of action of ONC213 and enable biomarker selection for clinical studies.

"Our team at the Karmanos Cancer Institute is excited by the potential of ONC213 as a new type of cancer therapy," said Dr. Yubin Ge. "We look forward to continuing development of this novel agent as it makes its way towards the clinic."
