A better test for the tumor-targeting of CAR-T therapies

On November 6, 2020 Ludwig Cancer Research scientists reported that have developed a method to significantly improve the preclinical evaluation of chimeric antigen-receptor (CAR) T cell therapies, in which the immune system’s T cells are extracted from a patient, engineered to target a specific tumor-associated molecule and then grown and reinfused for cancer treatment (Press release, Ludwig Institute For Cancer Research, NOV 6, 2020, View Source [SID1234570273]). Published in the Journal of Experimental Medicine, the study also reports the construction and evaluation of co-engineered CAR-T cells and applies the method to examine their effects on tumors in a mouse model of the skin cancer melanoma.

Though CAR-T therapies have been approved for blood cancers, their application to solid tumors has proved challenging. This is in part because the complex microenvironments of solid tumors dampen immune responses in a variety of ways, not least through the recruitment of various suppressive immune cells.

"Most of the studies on CAR-T therapies have been done using human T cells in mice that lack their own immune system—because if they had one, it would attack the human CAR-T cells," said Melita Irving, a researcher at the Ludwig Institute for Cancer Research Lausanne Branch who led the study with Ludwig Lausanne Director George Coukos. "But the tumor microenvironment can have a huge impact on your T cell product, so we’re really interested in doing studies using engineered mouse T cells in immunocompetent mice. This allows us to observe the dynamic interplay between the immune system and the CAR-T cells that we transfer."

Trouble is that mouse T cells are difficult to engineer and expand optimally in culture in the numbers required to rigorously model CAR-T cell therapies. For the current study, the Ludwig Lausanne team first developed a protocol to overcome those difficulties. It involved, among other things, the sequential use of three immune signaling molecules known as interleukins (IL-2, 7 and 15) in the cultivation and expansion of the engineered T cells.

They showed that CAR-T cells cultured using the protocol are markedly activated when exposed to their target. The cells also show signs of being more youthful and have molecular features common to memory T cells that grow briskly when stimulated by their targets.

"This means that when you transfer these cells, they’re very robust cells and can really expand quickly to control tumors," said Irving.

Irving, Coukos and colleagues then engineered their cultured mouse T cells to co-express, along with the chimeric antigen receptor, the IL-15 protein—which promotes the formation of memory T cells. They then examined the efficacy of these "fourth generation" (4G) CAR-T cells against a mouse model of melanoma and compared their activity to that of ordinary mouse CAR-T cells generated using the novel protocol.

"We saw better tumor control by the IL-15 expressing CAR-T cells and better proliferation and persistence of the CAR-T cells themselves," said Irving. The 4G CAR-T cells were also less prone to programmed cell death and expressed lower levels of a cell surface protein named PD-1, which promotes T cell suicide.

Their analysis revealed that the 4G CAR-T cells were not just killing cancer cells more efficiently. They were also reprogramming the microenvironment of the tumor to augment such killing. Their use resulted in an activation of natural killer cells—which target cancer cells—in the tumor microenvironment, and a marked decline in M2 macrophages, which suppress anti-tumor immune responses and support tumor growth.

"We hope that our publication of this protocol will help the T cell engineering community in general and enable a more robust preclinical evaluation of T cell therapies," said Irving.

This study was supported by Ludwig Cancer Research, the European Research Council, the Biltema Foundation and Oncosuisse.

In addition to his Ludwig post, George Coukos directs the Department of Oncology at the University Hospital of Lausanne (CHUV-UNIL) and co-directs the Swiss Cancer Center, Léman. Melita Irving is also a group leader within the department of oncology, UNIL CHUV.

"We submitted our NDA for ibrexafungerp for the treatment of vaginal yeast infections ahead of schedule and, with approval anticipated in mid-2021, we continue to progress towards our transition into a fully integrated commercial-stage antifungal company with an initial focus on women’s health," said Marco Taglietti, M.D., President and Chief Executive Officer of SCYNEXIS. "In parallel, we are also advancing clinical trials evaluating ibrexafungerp’s potential to treat invasive fungal infections in the hospital setting, with additional data read-outs expected in 2021."

Ibrexafungerp Update

SCYNEXIS recently announced the submission of its NDA to the U.S. Food and Drug Administration (FDA) for oral ibrexafungerp for the treatment of VVC, also known as vaginal yeast infection. The submission occurred in October and SCYNEXIS expects to receive FDA feedback on the acceptability of this submission in December. As a qualified infectious disease product (QIDP), ibrexafungerp is expected to receive a six-month priority review following NDA acceptance with a PDUFA date anticipated in mid-2021.

Enrollment is ongoing in the Phase 3 CANDLE study, investigating the efficacy and safety of oral ibrexafungerp for the prevention of recurrent VVC, for which there is no approved therapy in the U.S. Pending successful completion of this trial, SCYNEXIS anticipates top-line results and the submission of a supplemental NDA for this indication in the second half of 2021.

Enrollment is ongoing in our refractory invasive fungal infections (rIFI) program, which comprises two open-label Phase 3 studies (FURI and CARES). Similar to the two interim analyses of previously reported data, SCYNEXIS intends to analyze the outcomes from the next cohort of patients that have completed their treatment course in both FURI and CARES studies and announce these findings when available.

Enrollment is ongoing in the Phase 2 SCYNERGIA study for patients with invasive aspergillosis evaluating oral ibrexafungerp in combination with voriconazole. Top-line data from this study are expected in the second half of 2021.

Pre-clinical activities are also ongoing towards the development of a liposomal intravenous formulation of ibrexafungerp.

Data presentations. In October 2020, SCYNEXIS presented ibrexafungerp data at two scientific conferences. The first was the Nurse Practitioners in Women’s Health (NPWH) held virtually on October 15-17, where SCYNEXIS showcased in vitro activity of ibrexafungerp against fluconazole-susceptible and -resistant Candida species, as well as data from the Phase 3 VANISH-303 trial in VVC. The second October conference was IDWeek 2020 held virtually on October 21-25. At this conference SCYNEXIS presented an interim analysis from its ongoing Phase 3 FURI trial in refractory infections and pre-clinical data highlighting the potential for ibrexafungerp use in invasive fungal infections. In August 2020, SCYNEXIS presented its full data set from the Phase 3 VANISH-303 VVC trial at the Infectious Diseases Society for Obstetrics and Gynecology (IDSOG). Some of the posters presented are available here.
Corporate Developments

On July 17, 2020, SCYNEXIS executed a 1-for-10 reverse split of its issued and outstanding common stock.
Third Quarter Financial Results

Cash and cash equivalents totaled $29.5 million as of September 30, 2020, compared to $48.4 million in cash, cash equivalents, and short-term investments at December 31, 2019.

Research and development expense for the three months ended September 30, 2020 decreased to $8.0 million from $9.3 million for the three months ended September 30, 2019. The decrease of $1.2 million, or 13%, for the three months ended September 30, 2020, was primarily driven by a decrease of $2.0 million in clinical development expense, and a decrease of $0.5 million in preclinical expense, offset in part by an increase in regulatory expense of $0.6 million, an increase of $0.3 million in chemistry, manufacturing, and controls (CMC) expense, and a net increase in other research and development expense of $0.4 million.

Selling, general and administrative expenses for the quarter ended September 30, 2020 increased to $3.5 million from $2.5 million for the quarter ended September 30, 2019. The increase of $1.0 million, or 40%, for the three months ended September 30, 2020 was primarily driven by a $0.8 million increase in professional fees and commercial related expenses recognized during the three months ended September 30, 2020.

Total other income was $12.4 million for the quarter ended September 30, 2020, compared to total other income of $3.8 million for the quarter ended September 30, 2019. During the quarter ended September 30, 2020 and 2019, SCYNEXIS recognized non-cash gains of $7.8 million and $1.8 million, respectively, on the fair value adjustment of the warrant liabilities and during the quarter ended September 30, 2020 and 2019, recognized non-cash gains of $5.3 million and $2.3 million on the fair value adjustment of the derivative liabilities, respectively.

Net income for the quarter ended September 30, 2020 was $0.9 million, or $0.09 per basic and ($0.28) per diluted share, compared to a net loss of $7.9 million, or ($1.43) per basic and ($1.45) per diluted share for the quarter ended September 30, 2019.

About Ibrexafungerp

Ibrexafungerp [pronounced eye-BREX-ah-FUN-jerp] is an investigational antifungal agent and the first representative of a novel class of structurally-distinct glucan synthase inhibitors, triterpenoids. This agent combines the well-established activity of glucan synthase inhibitors with the potential flexibility of having oral and intravenous (IV) formulations. Ibrexafungerp is currently in development for the treatment of fungal infections caused primarily by Candida (including C. auris) and Aspergillus species. It has demonstrated broad-spectrum antifungal activity, in vitro and in vivo, against multidrug-resistant pathogens, including azole- and echinocandin-resistant strains. The FDA has granted Qualified Infectious Disease Product (QIDP) and Fast Track designations for the formulations of ibrexafungerp for the indications of invasive candidiasis (IC) (including candidemia), invasive aspergillosis (IA) and VVC, and has granted Orphan Drug Designation for the IC and IA indications. Ibrexafungerp is formerly known as SCY-078. (Press release, Scynexis, NOV 6, 2020, View Source [SID1234570270])
