CTL019 for multiple myeloma

by juliofrippo on Tue Jul 08, 2014 9:24 am

According to a recent news release (see below), a personal immunotherapy (CTL019) has resulted in a complete response (cancer undetectable) in 89 percent of patients suffering with acute lymphoblastic leukemia. This therapy targets protein CD19 which produces cancer cells.

I believe that CD19 is the protein that is also prevalent in multiple myeloma patients. Ongoing testing is also being conducted with other cancers including multiple myeloma. The article didn't give any information on the test results for multiple myeloma patients.

Does anyone have any additional information on this therapy?

Novartis personalized cell therapy CTL019 receives FDA Breakthrough Therapy designation

  • Designation supports the advancement of CTL019 to help address the unmet need of patients with relapsed/refractory acute lymphoblastic leukemia (r/r ALL)
  • The filing was submitted by the University of Pennsylvania's Perelman School of Medicine which is conducting the CTL019 Phase I/II clinical trials
  • Novartis and Penn have exclusive global collaboration to research, develop and commercialize CAR T cell therapies for the investigational treatment of cancers
Basel, July 7, 2014 - Novartis announced today that the United States Food and Drug Administration (FDA) has granted Breakthrough Therapy status to CTL019, an investigational chimeric antigen receptor (CAR) therapy for the treatment of pediatric and adult patients with relapsed/refractory acute lymphoblastic leukemia (r/r ALL). The Breakthrough Therapy filing was submitted by the University of Pennsylvania's Perelman School of Medicine (Penn) which has an exclusive global agreement with Novartis to research, develop and commercialize personalized CAR T cell therapies for the treatment of cancers.

This is the fifth Breakthrough Therapy designation for Novartis, continuing the company's trajectory as a leader in developing innovative therapies to help treat diseases in which there remains significant unmet medical need[1],[2],[3],[4]. Novartis' Zykadia(TM) (ceritinib, previously known as LDK378), for the treatment of anaplastic lymphoma kinase positive (ALK+) metastatic non-small cell lung cancer (NSCLC), is one of the first medicines to receive an FDA approval following earlier receipt of Breakthrough Therapy designation by the FDA[5].

"This Breakthrough Therapy designation underscores the potential of CTL019 as a life-saving therapy for patients with relapsed/refractory ALL, who are in desperate need of new treatment options," said David Epstein, Division Head, Novartis Pharmaceuticals. "Novartis welcomes increased dialogue with the FDA and a potentially expedited review to streamline the development of CTL019 and hopefully bring this promising therapy to patients as quickly as possible."

According to the FDA, Breakthrough Therapy designation is intended to expedite the development and review of new medicines that treat serious or life-threatening conditions if the therapy has demonstrated substantial improvement over an available therapy on at least one clinically significant endpoint. The designation includes all of the fast track program features, as well as more intensive FDA guidance. It is a distinct status from both accelerated approval and priority review, which can also be granted to the same drug if relevant criteria are met[6].

"This is a major milestone as we are now one step closer in helping address the high unmet needs of this patient population," said Carl H. June, M.D., Richard W. Vague Professor in Immunotherapy in the department of Pathology and Laboratory Medicine in the Perelman School of Medicine and director of Translational Research in the Abramson Cancer Center of the University of Pennsylvania. "We are excited about the strength of the positive early data seen in pediatric and adult patients with relapsed/refractory acute lymphoblastic leukemia and look forward to building upon these findings as we continue advancing the CTL019 clinical program in Phase II trials."

Novartis recently established the Cell and Gene Therapies Unit under the leadership of Usman Azam, Global Head, to bring an intense focus on advancing innovative cell-based therapies, including the development of CARs. Novartis holds the worldwide rights to CARs developed through the collaboration with Penn for all cancer indications, including the lead program, CTL019.

About CTL019
CTL019 uses CAR technology to reprogram a patient's own T cells to "hunt" cancer cells that express specific proteins, called CD19. After they have been reprogrammed, the T cells (now called CTL019) are re-introduced into the patient's blood; they proliferate and bind to the targeted CD19+ cancer cells and destroy them.

Because CTL019 is an investigational therapy, the safety and efficacy profile has not yet been established. Access to investigational therapies is available only through carefully controlled and monitored clinical trials. These trials are designed to better understand the potential benefits and risks of the therapy. Because of uncertainty of clinical trials, there is no guarantee that CTL019 will ever be commercially available anywhere in the world.

Hi JulioFrippo,

Thanks for your posting. This doesn't completely address the questions you've asked, but, just as an FYI, you can find a lot of background information about CTL019 in this recent forum posting we made:

"Pfizer bets on Cellectis (and CAR-T)"

The posting includes a number of links to articles at The Beacon and elsewhere that describe the technology behind CTL019 and efforts being made to develop other treatments similar to it.

Finally, this thread here in the forum with regularly updated information about research into this approach to treating multiple myeloma:

"CAR T-cell immunotherapy for multiple myeloma" (started Apr 7, 2014)

Hope that helps a bit.

The 19 in CTL019 is short for CD19, the target found on all B cells and almost all cancerous B cells. Plasma cells and cancerous plasma cells (multiple myeloma) do not express CD19. However, the UPenn team is working on other targets for CAR T cells to treat multiple myeloma.

While CD19 is not found on multiple myeloma cells, there are studies to show that it is found on the multiple myeloma cancer stem cell, although this is controversial, and no company is de­vel­oping their CD19 CAR T cell products to treat these putative cancer stem cells. There are CAR T cell products in development that do target multiple myeloma cells, but right now it is the use of CAR T cells that target CD19 that is farthest ahead and showing promising results in the treatment of B-cell leukemia and lymphoma.
