Nanjing Sanpower, a major China conglomerate, has "sold" its Dendreon pharmaceutical subsidiary by transferring Dendreon to another of Sanpower's holdings, the China retail company Cenbest, in exchange for $868 million of stock.

Sanpower explains that Dendreon, as part of Cenbest, will find it easier to raise the money it needs to expand, probably into CAR-T or some other cell therapy. Before the transaction, Sanpower owned 33% of Cenbest. Now it owns 42%.

Trials and Approvals

Gilead Sciences (NSDQ: GILD) received approval from the China National Drug Administration of its combination-drug treatment for HIV-1. Genvoya is a single tablet made up of four drugs including tenofovir alafenamide. According to Gilead, Genvoya is the first TAF-based single tablet regimen approved in China for HIV. Since 2003, China has been providing free antiretroviral treatment to all patients with HIV.

BeiGene (NSDQ: BGNE; HK: 06160), a Beijing oncology biopharma, dosed the first patient in a China Phase III trial of its PD-1 antibody as a first-line treatment for lung cancer. According to BeiGene's count, the trial is the ninth indication for the PD-1 candidate, tislelizumab. The latest trial combines tislelizumab with chemotherapy to treat China patients with squamous non-small cell lung cancer. One year ago, BeiGene out-licensed global rights (ex-Asia) for tislelizumab to Celgene (NSDQ: CELG) in a $1.4 billion agreement.

I-Mab Biopharma, a Shanghai company developing immuno-oncology and immuno-inflammation drugs, has been approved to begin China trials of a novel type 2 diabetes treatment. The candidate, TJ103, is an injected, humanized long-acting recombinant glucagon-like peptide-1 (hGLP-1) fused with a hybrid Fc (hyFc). Unlike many diabetes drugs, members of the GLP-1 class have a low risk of causing hypoglycemia. China does not currently have any approved long-acting GLP-1 treatments, I-Mab noted.

Shanghai's I-Mab BioPharma submitted an IND in China for approval to conduct clinical trials of its immuno-oncology multiple myeloma treatment. TJ202/MOR202 is a mAb that is directed against CD38, activating the immune system's killer cells. One year ago, I-Mab in-licensed China rights to the candidate from Germany's MorphoSys (FSE: MOR; NSDQ: MOR) in a $120 million agreement. MorphoSys has started Phase II trials of the drug in Germany and Austria.

IPO Watch

So far, two young China biopharmas have debuted on the Hong Kong exchange, encouraged by the much-heralded new IPO rules for pre-revenue companies. Unfortunately, the market's response has been lukewarm. Ascletis (HK: 1672) raised $400 million, about the middle of its projected range, but after a week and a half of trading, the company's new shares have declined 15%. BeiGene (NSDQ: BGNE; HK: 6160) raised $900 million, pricing the offering at the bottom of the range (and a small discount to its NASDAQ quote). It has declined 5% from its offering price in three trading sessions. There are six other pre-revenue China biopharmas that have filed for Hong Kong IPOs and several more planning to do so. The post-IPO performance of the first two could dampen the pricing of these offerings.
