On May 14, 2018 CStone Pharmaceuticals (CStone) reported dosing of the first patient in a Phase I clinical trial in Australia for CS1003, an investigational anti-programmed death-1 (PD-1) monoclonal antibody (mAb) (Press release, CStone Pharmaceauticals, MAY 14, 2018, View Source [SID1234526640]). The open-label, first-in-human (FIH) study is initiated at Scientia Clinical Research Ltd in Australia and will investigate the safety, tolerability, and preliminary efficacy of CS1003 in patients with advanced solid tumors.

"We are excited to announce initiation of clinical development for PD-1 inhibitor CS1003, our second pipeline candidate to enter Phase I studies in Australia after the CTLA-4 mAb CS1002 within one month," said Dr. Frank Jiang, Chief Executive Officer at CStone. "CS1003 is cross-reactive with human and mouse PD-1 which enables quick pre-clinical proof of concept experiments in combination with novel targets, leading to global first-in-combination potential. Because of this unique feature, CS1003 is critical to CStone’s combination strategy in cancer immunotherapy."

The launch of clinical studies for CS1003 is a key milestone for CStone, which now has three important checkpoint inhibitors for cancer therapy under clinical development. Alongside CS1001 (PD-L1) and CS1002 (CTLA-4), CS1003 will provide the backbone for CStone’s pipeline development of oncology combination therapies.

As noted by Dr. Jason Yang, Chief Medical Officer of CStone, "In preclinical studies, CS1003 demonstrated high affinity and selectivity for PD-1, as well as synergistic anti-tumor effects with multiple small-molecule drugs in animal models. The launch of this clinical program will allow us to gather important safety and efficacy data on CS1003. This will lay the foundation for future development of this molecule, in particular as the basis of combination therapies."

"We are excited to be enrolling our first patient treated with CS1003 and are hopeful that this novel immunotherapy drug will add to the available therapeutic options for advanced-stage tumors, either by itself or in combination with other drugs," said Dr. Charlotte Lemech, MBBS, BSc, FRACP, MD, lead investigator for this trial at Scientia Clinical Research Ltd.

The Phase Ia/Ib study includes a dose-escalation stage followed by a dose-expansion stage. Additional information on the trial can be found here.

About CS1003 and the PD-1/PD-L1 pathway

CS1003 is a humanized anti-PD-1 IgG4 monoclonal antibody developed by CStone using an internationally leading hybridoma platform. CS1003 has shown good tolerability and efficacy profile in preclinical in vivo studies.

PD-1, or programmed death-1, is an inhibitory checkpoint receptor expressed on T cells. Under normal circumstances, it binds with its ligands, programmed death ligand-1 or ligand 2 (PD-L1/PD-L2), inhibiting T cell and cytokine activation, serving to dampen the immune response in order to prevent damage to healthy tissues. However, studies have shown that PD-L1 can be abundantly expressed on the surface of many solid tumors as well as hematological malignancies. Cancer cells can therefore make use of the PD-1/PD-L1 pathway to successfully avoid immune system recognition and attack. Targeting of the PD-1/PD-L1 checkpoint by anti-tumor drugs can block the "tumor immune evasion mechanism" and restore anti-cancer immune ability in patients.

Currently, there are two anti-PD-1 antibodies approved globally: Opdivo (nivolumab) from Bristol-Myers Squibb and Keytruda (pembrolizumab) from Merck, Sharp & Dohme. Unlike other anti-PD-1 mAbs, CS1003 recognizes both human and murine PD-1, providing a unique competitive advantage during efficacy testing in syngeneic mouse tumor models particularly for development of effective combination therapies.

"We are very pleased with the clinical results we have generated to date for MT-3724, which we expect to enter Phase II studies in relapsed/refractory DLBCL patients in the second half of 2018," said Eric Poma, Ph.D., CEO and CSO of Molecular Templates. "In the next twelve months, we expect our clinical pipeline to expand significantly as we file INDs for MT-4019 as well as our ETBs targeting HER2 and PD-L1."

Company Highlights and Upcoming Milestones

Corporate

At the American Association of Cancer Research (AACR) (Free AACR Whitepaper) annual meeting in April 2018, preclinical data were presented for Molecular’s ETBs targeting PD-L1 (which incorporates Molecular’s Antigen Seeding Technology – a differentiated immune-oncology approach) and HER2.
On March 2, 2018, Molecular closed a $10 million debt facility with Perceptive Advisors. The proceeds were used to repay an existing debt facility with Silicon Valley Bank and will support Molecular’s build out of its GMP manufacturing facility, to support Molecular’s own pipeline as well as partnerships. The first tranche of $5 million was received in 1Q18 and the second tranche of $5 million is due to be received in 3Q18.
MT-3724

MT-3724 (an ETB targeting CD20) is in an ongoing Phase Ib expansion study intended to better define the single agent overall response rate in heavily pre-treated diffuse large B-cell lymphoma (DLBCL) patients with additional updates expected in 2Q18.
Molecular also expects to initiate Phase II combination studies with MT-3724 in earlier lines of DLBCL in 2H18.
MT-4019

MT-4019 (an ETB candidate designed to target CD38-expressing myeloma cancer cells) is progressing through IND enabling studies.
Takeda and Molecular are evaluating CD38 ETBs and could potentially select a drug candidate for development by the end of 3Q18. If the two companies do not select a joint candidate for development, Molecular anticipates filing an IND application for MT-4019 in 3Q18 and initiating a Phase I clinical trial in 2H18.
Research

Molecular expects to file an IND application for an ETB targeting HER2 in 4Q18.
Molecular expects to file an IND application for an ETB targeting PD-L1 (with antigen seeding) in 1Q19.
Several other ETB candidates are in pre-clinical development, targeting both solid and hematological cancers.
Takeda Multi-Target Collaboration

In December 2017, Takeda selected two targets for further research using Molecular’s ETBs. This triggered $4 million in milestone payments, which were paid by Takeda in 2Q18.
Financial Results

The net loss attributable to common shareholders for the first quarter was $8.7 million, or $0.32 per basic and diluted share. This compares with a net loss attributable to common shareholders of $1.6 million, or $7.56 per basic and diluted share for the same period in 2017.

Revenues for the first quarter of 2018 were $0.5 million, compared to $1.9 million for the same period in 2017. Revenues for the first quarter of 2018 and 2017 were comprised of grant revenue from the Cancer Prevention & Research Institute of Texas, and revenues from collaborative research and development agreements. Total research and development expenses for the first quarter of 2018 were $6.7 million, compared with $1.1 million for the same period in 2017. Total general and administrative expenses for the first quarter of 2018 were $2.9 million, compared with $1.8 million for the same period in 2017.
