Results from the CALM (UCART19 in Advanced Lymphoid Malignancies) study will be shared as an oral presentation by Reuben Benjamin, principal investigator and consultant hematologist at King’s College Hospital, United Kingdom, on December 11 at 7.15 pm (EST). The CALM study is an open label, dose-escalation study designed to evaluate safety, tolerability and antileukemic activity of UCART19 in patients with relapsed or refractory CD19-positive B-cell acute lymphoblastic leukemia (B-ALL). The study was initiated in the UK in August 2016.

The PALL (Pediatric Acute Lymphoblastic Leukemia) study is a phase 1, open label, study to evaluate the safety and the ability of UCART19 to induce molecular remission in pediatric patients with relapsed or refractory B-ALL. PALL was initiated in the UK in June 2016. Waseem Qasim, principal investigator of the PALL study and consultant in pediatric immunology and reader in cell and gene therapy at Great Ormond Street Hospital for Children, United Kingdom, will present results from the trial during a poster session on December 9 from 5.30 pm to 7.30 pm.

Servier is a sponsor of both studies. In 2015, Servier acquired exclusive rights from Cellectis for UCART19, which is being codeveloped by Servier and Pfizer.

About UCART19

UCART19 is an allogeneic CAR T-cell product candidate being developed for treatment of CD19-expressing hematological malignancies, gene edited with TALEN. UCART19 is initially being developed in acute lymphoblastic leukemia (ALL) and is currently in Phase I. The current approach with UCART19 is based on the preliminary positive results from clinical trials using autologous products based on the CAR technology. UCART19 has the potential to overcome the limitation of the current autologous approach by providing an allogeneic, frozen, “off-the-shelf” T cell based medicinal product.

In November 2015, Servier acquired the exclusive rights to UCART19 from Cellectis. Following further agreements, Servier and Pfizer began collaborating on a joint clinical development program for this cancer immunotherapy. Pfizer has been granted exclusive rights by Servier to develop and commercialize UCART19 in the United States, while Servier retains exclusive rights for all other countries.

Cellectis Announces Two Oral Presentations and One Poster Presentation at the 2017 ASH Annual Meeting

“Previously reported top-line data from the pivotal Phase 3 DUO study significantly favored duvelisib monotherapy over ofatumumab, an approved standard of care treatment for patients with relapsed or refractory CLL/SLL, achieving a statistically significant improvement in median PFS and a hazard ratio (HR) of 0.52 (p<0.0001), with a consistent and manageable safety profile," said Robert Forrester, President and Chief Executive Officer of Verastem. "We look forward to sharing the detailed results from the DUO study with the medical community at ASH (Free ASH Whitepaper) this year."

Verastem recently announced that a meeting was held with the U.S. Food and Drug Administration (FDA) regarding the regulatory path for duvelisib. Based on the meeting with, and written feedback from the FDA, Verastem intends to submit a New Drug Application (NDA) requesting the full approval of duvelisib for the treatment of patients with relapsed or refractory CLL/SLL and accelerated approval for the treatment of patients with relapsed or refractory follicular lymphoma (FL). Along with the clinical data from the DUO study, the duvelisib NDA submission will also contain the favorable results from the Phase 2 DYNAMO study in double-refractory indolent non-Hodgkin’s lymphoma (iNHL), which also achieved its primary endpoint with an ORR of 46% (p<0.0001). In the subset of patients enrolled in the DYNAMO study with double-refractory FL (n=83), duvelisib demonstrated an ORR of 41%. The Company expects to submit the duvelisib NDA during the first quarter of 2018.

Details for the ASH (Free ASH Whitepaper) 2017 presentations are as follows:

About Duvelisib
Duvelisib is a first-in-class investigational, dual inhibitor of phosphoinositide 3-kinase (PI3K)-delta and PI3K-gamma, two enzymes known to help support the growth and survival of malignant B-cells and T-cells. PI3K signaling may lead to the proliferation of malignant B-cells and is thought to play a role in the formation and maintenance of the supportive tumor microenvironment.1,2,3 Duvelisib is currently being evaluated in late- and mid-stage extension trials, including DUO, a randomized, Phase 3 monotherapy study in patients with relapsed or refractory chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL),4 and DYNAMO, a single-arm, Phase 2 monotherapy study in patients with refractory indolent non-Hodgkin lymphoma (iNHL).5 Both DUO and DYNAMO achieved their primary endpoints and Verastem intends to submit a New Drug Application (NDA) requesting the full approval of duvelisib for the treatment of patients with relapsed or refractory CLL/SLL, and accelerated approval for the treatment of patients with relapsed or refractory follicular lymphoma (FL). Duvelisib is also being developed by Verastem for the treatment of peripheral T-cell lymphoma (PTCL), and is being investigated in combination with other agents through investigator-sponsored studies.6 Information about duvelisib clinical trials can be found on www.clinicaltrials.gov.
