California Award Recipient: 'Promising' Results from Chinese Stem Cell Trial for Knee Arthritis

Cellular Biomed has a four-year U.S. history

A Chinese biomedical firm that popped up last month with an award from the $3 billion California stem cell agency is working with the University of Southern California and Children's Hospital in Los Angeles to ready an arthritis therapy for a clinical trial in the United States.

The publicly traded enterprise is Cellular Biomedicine Group, Inc., which has an office in Cupertino, Ca., as well as China. It was awarded $2.3 million from the California Institute for Regenerative Medicine or CIRM, as the state stem cell agency is formally known.

The company said in a press release that the therapy, known as AlloJoin, is already in a phase one clinical trial in China where it is showing "promising interim 3-month safety data." The company described the therapy as an “off-the-shelf, allogeneic, human adipose-derived, mesenchymal stem cell" treatment.

The company said it is working with C. Thomas Vangsness, Jr., at the Keck School of Medicine at USC, and Qing Liu-Michael of the Broad Center for Regenerative Medicine, also at USC. Vangsness will be principal investigator on the company's phase one U.S. trial.


The company said the CIRM grant is the first step in bringing its arthritis treatment to the United States. It is also contributing $572,993 to the work  being funded by the state agency.

In an interview last week with Javier Hasse of Benzinga, an online financial information site, Tony Liu, chief executive officer of Cellular, said his company is also working on  immune cell therapies involving cancer. He said his company's focus is on China because of the size of the market.

Liu said,

"In China, 57 million people have a knee issue; in the U.S., 27 million [people] have a knee issue. Stem cells can help knees regenerate by doing two things. First, by helping with the pain, providing symptom relief and functional improvements. Secondly, they regenerate the cartilage, which originally caused the knee problem. Nowadays, patients can only opt between pain pills or a knee replacement.

Today, if you do a knee replacement, you are looking at tens of thousands [of dollars]. So, any way you look at it, [it’s a] multi-billion [market] for knee treatments."

Liu continued,

“Our management team was educated in the U.S., and has experience managing large businesses.... “Our chief scientific officer is a former MedImmune/AstraZeneca plc (ADR) (NYSE: AZN) director. Some of our oncology scientists are from there as well. We also have scientists from the National Cancer Institute. We also have a person who is leading our manufacturing capabilities who worked for Harvard for 30 years and a top German company, leading research for seven years total.”

“So, we have this kind of people with skills come to China. Our company has 130 people with PhDs, and more than 30 with post-doctorate studies, so there is a lot of brain power, I believe, and we have a  common vision that is to create the best, first in class, biotech business in China.”

As for the company's finances, Liu said,

"CBMG’s stock is really thinly traded. Much of the stock is owned by those who have been with the company for a long time; so, they don’t sell. Having said this, there are many reasons that drive stocks: the U.S. election, the pricing discussion… Many investors don’t discriminate, and just punish biotech as a whole. However, CBMG is not really subject to most of these pricing pressures. In fact, because we have a different cost structure, I expect CBMG to do extremely well." 

Diabetes to Arthritis: California Awards $33 Million for Clinical Stage Stem Cell Work

The California stem cell agency today approved nearly $33 million for clinical stage research projects testing treatments for type 1 diabetes, arthritis of the knee, ALS and an immunodeficiency affliction.

The awards were quickly approved with little discussion during a meeting at the Oakland headquarters of the California Institute for Regenerative Medicine or CIRM, as the agency is formally known.

The award likely to have an impact on the most people -- if it is successful -- is a relatively small, $2.3 million award to the Cellular Biomedicine Group,  a Chinese firm with operations in Cupertino, Calif. The stem cell agency by law only finances work in California. The research would also be supported by $572,993 in co-funding.

The project is aimed at treating osteoarthritis of the knee. More than 51 million people in the United States suffer from arthritis, which is particularly common in the knee.

The goal of the research is to regenerate knee cartilage through the use of a mesenchymal progenitor cell treatment, according to the agency's application review summary. The funding would go to manufacture the product and complete work to secure Food and Drug Administration approval for a phase one safety trial. A treatment for the public would likely be years in the future.

Here are the other winners today of California stem cell cash with links to the summaries of the reviews.

Caladrius Biosciences of New Jersey won $12.2 million for a clinical trial for young people ages 12-17 for newly diagnosed type 1 diabetes. The firm plans to use regulatory T cells from the patients themselves to treat the disease. Caladrius has a California location in Mountain View. (Caladrius' press release can be found here.)

St. Jude's Research Hospital in Memphis, Tenn., was awarded $11.9 million for a phase one/two trial to treat infants with X-linked severe combined immunodeficiency. The trial would aim at enrolling at least six patients suffering from the catastrophic affliction. The treatment would use the patients own bone marrow stem cells after the cells were specially handled. The agency said in a press release that St. Jude's is working with UC San Francisco. (St. Jude's press release can be found here.)

Cedars-Sinai Medical Center in Los Angeles was awarded $6.2 million for a phase 1/2A trial to test a treatment for ALS, which has no treatment or cure. The CIRM review summary said a "huge unmet need" existed. About 20,000 persons in the United States suffer from the affliction.

CIRM's press release did not identify the researchers involved in any of the awards.

The agency is on a push to support more clinical trials, which are the last and most expensive research prior to the possibility of winning federal approval for widespread use of a therapy.

Currently the agency is participating in 27 trials and is planning on adding 37 more in the next 40 months. The agency is expected to run out of funds for new awards in June 2020 and has no source of future financing.

The awards were previously approved behind closed doors by the agency's out-of-state reviewers, who do not disclose publicly their economic or professional interests. The agency's directors rarely overturn a positive decision by the reviewers.

All of the winners have links to two or more members of the 29-member CIRM governing board. Those members are not allowed to vote on applications where they have conflicts of interest.
About 90 percent of the funds awarded by the board since 2005 have gone to institutions that have ties to members of the board, past or present, according to calculations by the California Stem Cell Report.

(Editor's note: An earlier version of this item incorrectly said the total amount of awards was $37 million.)

Millions More on the Way: California Stem Cell Agency Beefing Up Fight to Reverse Arthritis

California's $3 billion stem cell agency appears ready to back with millions of dollars a proposed therapy intended to reverse arthritis -- an affliction that affects 40 million Americans --  and push the treatment into clinical trials.

It would be the first ever disease-modifying therapeutic for osteoarthritis if it clears clinical trials, which could take years.

Peter Schultz, chief executive officer of the Scripps Research Institute, last month indicated that the therapy was all but assured of funding by the California Institute for Regenerative Medicine (CIRM), as the stem cell agency is formally known.

Shultz' disclosure came at the end of an Oct. 20 article by Bradley Fikes in the San Diego Union Tribune. Schultz said,

"We’re just finishing (toxicology studies) with a regenerative medicine for osteoarthritis that [the California Institute for Regenerative Medicine] wants to fund. That’ll be dosed in patients probably in the first quarter of next year."

Schultz did not respond to a request for additional comment from the California Stem Cell Report. The stem cell agency itself does not identify applicants, with a few notable exceptions, for funding unless they actually receive awards.

Schultz, however, has already received about $10 million for a therapy (see here and here) aimed at tweaking cells to reverse the course of arthritis, which would be the basis for a clinical trial.

In an undated progress report filed with CIRM, Schultz said,

 "A unique and unexplored therapeutic opportunity exists to induce somatic stem cells to regenerate the damaged tissue and reverse the chronic destructive process. Because limited joints are affected in most (osteoarthritis) patients, intra-articular (IA) drug injection is an attractive treatment approach that allows high local drug concentration with limited systemic exposure. Targeting resident stem cells pharmacologically also avoids the risks and costs associated with cell-based approaches."

Schultz also said in the CIRM document,

"The primary objective of this project is to develop a non-invasive, therapeutic for the regeneration of cartilage in OA. This new therapy will target the resident MSCs in the joint, stimulate production of new cartilage matrix, promote repair and thus limit additional joint damage and improve joint pain and function."

The CIRM document included an accounting of achievements in the research involving animals. The document said,

"We have demonstrated efficacy in preclinical in vivo models of a potential drug candidate for the treatment of osteoarthritis. The small molecule functions by selectively differentiating meschenchymal stem cells to chondrocytes to repair damaged cartilage."

In another CIRM document, Schultz reported that "a scale-up manufacturing process has been developed and confirmed feasible" and would be used in the initial clinical trials.

An award could be made publicly to Schultz before the end of the year at meetings of the full board of the stem cell agency in 10 days or in December.

California Stem Cell Agency Awards $1.7 Million to Help Treat Arthritis

Directors of the California stem cell agency, as expected, this morning approved $1.7 million to help push an arthritis treatment into clinical trials. The funds went to Peter Schultz, director of the California Institute for Biomedical Research. We will have more details later today.

California Spending More than $19 Million on Search for Stem Cell Arthritis Therapy

Stem cell agency summary of Peter Schultz proposal

Highlights
First in class therapy
Avoids risks, costs
Uses drug-like kartogenin
The California stem cell agency tomorrow is set to boost its spending on arthritis to $19.5 million with a new grant to a San Diego researcher who is preparing a clinical trial for his possible therapy.

The agency’s governing board is all but certain to approve a $1.7 million award to Peter Schultz of the Scripps Research Institute in La Jolla on top of the $6 million he has already received.

Meeting behind closed doors, the agency’s blue-ribbon scientific reviewers earlier this summer approved the application on a 12-0 vote. The agency board almost never overturns a positive decision by its reviewers.

The review summary said the proposed therapy would be “first in class regenerative medicine” for osteoarthritis as well as cartilage injury. Currently no disease-modifying drugs are approved for clinical treatment of arthritis, which afflicts 27 million people in the United States. The award is to assist in preparation for a federally approved clinical trial.

Schultz, who has close ties to Merck and who is also director of the California Institute for Biomedical Research, laid out some details of his approach in an earlier progress report to the stem cell agency.

He said,

“Because limited joints are affected in most (osteoarthritis) patients, intra-articular drug injection is an attractive treatment approach that allows high local drug concentration with limited systemic exposure. Targeting resident stem cells pharmacologically also avoids the risks and costs associated with cell-based approaches.”

 Schultz continued,

“Cartilage contains resident mesenchymal stem cells (MSCs) that can be differentiated in vitro to form chondrocytes. This observation suggests that intra-articular injection of a small molecule that promotes chondrogenesis in vivo will preserve and regenerate cartilage in OA-affected joints. Using an image-based screen, we identified a drug-like small molecule, kartogenin (KGN), that promotes efficient and selective chondrocyte differentiation from MSCs in vitro. Intra-articular injection of KGN also shows beneficial effects in surgery-induced acute and enzyme-induced chronic cartilage injury models in rodents, as well as positive effects in incapacitance pain models.”

The agency has already pumped in around $17 million for arthritis research, including funds given earlier to Schultz.

As usual, the award tomorrow involves an institution that has a representative on the agency board. About 88 percent of the money that the agency has handed out since 2005 -- $1.9 billion -- has gone to institutions that have ties to agency directors, according to calculations by the California Stem Cell Report.

The stem cell agency does not identify the winning applicants for awards until after the board acts. However, based on information on the agency's Web site, the California Stem Cell Report was able to verify that Schultz was the applicant up for approval tomorrow.

Tomorrow’s teleconference meeting is scheduled for only one hour beginning at 9 a.m.. The main session will be in San Francisco, which has another location there as well. Other locations where the public can participate include Irvine, San Diego, Napa, Redwood City, two in Sacramento, Los Gatos, San Francisco, Elk Grove, Beverly Hills, Fresno, Los Angeles, Cambridge, Ma., and Ballard, Ca., in Santa Barbara County. Specific addresses can be found on the agenda.

The public can also make comments  on any issue during the board session.

(Editor's note: The figures on CIRM's total spending for arthritis have been increased from an earlier version of this story. The previous figures were based on erroneous numbers on the agency's "arthritis fact sheet," which did not include a $2.3 million award to Schultz in March.)
