Plasmacytoid dendritic cell neoplasms.

Review

Author: Kim, Youjin ; Lee, Yoo Jin ; Park, Sang Hyuk ; Jo, Jae-Cheol

Plasmacytoid dendritic cells (pDCs) are type I interferon-producing cells that modulate immune responses. There are two types of pDC neoplasms: 1) mature pDC proliferation (MPDCP) associated with myeloid neoplasm and 2) blastic pDC neoplasm (BPDCN). MPDCP is a clonal expansion of mature pDCs that is predominantly associated with chronic myelomonocytic leukemia. In contrast, BPDCN is a clinically aggressive myeloid malignancy involving the skin, bone marrow, lymphatic organs, and central nervous system. There are various types of skin lesions, ranging from solitary brown or violaceous to disseminated cutaneous lesions, which often spread throughout the body. The expression of CD4, CD56, CD123, and pDC markers (TCL-1, TCF4, CD303, and CD304, etc.) are typical immunophenotype of BPDCN. Historically, BPDCN treatment has been based on acute leukemia regimens and allogeneic hematopoietic cell transplantation in selected patients. Recent advances in molecular biology and genetics have led to the development of targeted agents, such as tagraxofusp (a recombinant fusion protein targeting CD123), anti-CD123 CAR-T cells, XmAb14045, and IMGN632. Lastly, this review provides a comprehensive overview of pDC neoplasms.

Abstract:

This study aimed to identify a recommended phase II dose and evaluate the safety, tolerability, pharmacokinetics/pharmacodynamics, and preliminary clinical activity of JNJ‐63709178, a CD123/CD3 dual‐targeting antibody, in patients with relapsed or refractory acute myeloid leukemia. Intravenous (i.v.) and subcutaneous (s.c.) administration of JNJ‐63709178 were evaluated. The i.v. infusions were administered once every 2 weeks (cohorts 1–5 [n = 17]) or twice weekly (cohorts 6–11 [n = 36]). A twice‐weekly s.c. dosing regimen with step‐up dosing was also studied (s.c. cohorts 1–2 [n = 9]). Treatment‐emergent adverse events (TEAEs) greater than or equal to grade 3 were observed in 11 (65%) patients in cohorts 1–5 and 33 (92%) patients in cohorts 6–11. At the highest i.v. dose (4.8 μg/kg), 5 (71%) patients discontinued treatment due to TEAEs. For s.c. administration (n = 9), eight (89%) patients experienced TEAEs greater than or equal to grade 3 and injection site reactions (≤ grade 3) emerged in all patients. At 4.8 μg/kg (i.v. and s.c.), the mean maximum serum concentrations were 30.3 and 3.59 ng/ml, respectively. Increases in multiple cytokines were observed following i.v. and s.c. administrations, and step‐up dosing strategies did not mitigate cytokine production or improve the safety profile and led to limited duration of treatment. Minimal clinical activity was observed across all cohorts. The i.v. and s.c. dosing of JNJ‐63709178 was associated with suboptimal drug exposure, unfavorable safety profiles, limited clinical activity, and inability to identify a recommended phase II dose.

UPDATED: Novartis washes its hands of another bispecific at the center of $2.5B Xencor deal

A centerpiece of Novartis’ $2.5 billion bispecifics deal with Xencor has been sidelined, the California biotech said in its third quarter earnings report Monday. Novartis terminated its ex-US rights to the program dubbed vibecotamab, a bispecific targeting CD123 and CD3 for acute myeloid leukemia. The move will take effect next February, Xencor said Monday. Xencor will drop development of the drug altogether as well, saying it has no future plans for in-house research. The Swiss biopharma previously handed back rights to the other Xencor drug involved in the partnership in January 2019. That program, a CD20 and CD3 bispecific called plamotamab, is now one of Xencor’s lead candidates, with updated Phase I data coming at ASH next month and a new partner signed in J&J’s Janssen. In Monday’s earnings call with analysts, Xencor CEO Bassil Dahiyat alluded to a tougher competitive landscape shrinking new opportunities in AML — following AbbVie and Roche’s 2019 approval of Venclexta — in response to a question about why Novartis backed out. He also noted CD123’s difficulty as a target, saying its “narrow therapeutic window” brings challenges in dosing frequency. “In spite of the very encouraging early complete remissions that we’ve had and continuing additional activity we’ve seen, all those pieces make the product profile and the competitive landscape tough, really frankly tough for us to want to pursue and our partner, Novartis, agree,” Dahiyat said. In an email to Endpoints News , a Xencor spokesperson said the deal remains ongoing, with the pair working on “a bispecific antibody and a non-bispecific antibody that incorporates another of our XmAb Fc domains.” Novartis and Xencor originally agreed to develop vibecotamab, previously known as XmAb14045, back in 2016 when the companies signed a deal giving Xencor $150 million upfront and promising another $2.4 billion in milestones. At the time, it had been the latest in a string of high-profile biopharmas to partner with Xencor, following Amgen, Merck and J&J, among others. But while vibecotamab was still a preclinical program in 2016, it soon ran into trouble in the clinic. The FDA slapped a hold on a Phase I study in February 2019 after two patients in the trial died, one from cytokine release syndrome and another from acute pulmonary edema following several doses. Regulators lifted the hold the following April, after Xencor amended study protocols to update how CRS is monitored and managed. It’s not clear if investigators ever determined whether the deaths were linked to the drug. Additional studies for vibecotamab had previously been scheduled for 2020, but Xencor said previously that plans had been affected by the Covid-19 pandemic. Now, though, those plans have been shelved. CD123 has given other drugmakers trouble in the past, as well as bispecifics with CD3. In 2016, the FDA put a full hold on a J&J program for the target combo, and Cellectis saw a patient death in 2017 for a CD123-targeting CAR-T candidate. Novartis, meanwhile, has its own in-house CD123 called JEZ567, being studied for AML. This article was updated to include comment from Xencor.

Novartis Walks Away from $2.6 Billion Xencor Collaboration

Taljat David/Shutterstock Shares of Xencor were down nearly 6% after the company announced Novartis terminated its rights to develop vibecotamab, a CD123 x CD3 blood cancer bispecific, which was part of a 2016 collaboration valued at $2.6 billion. Since the collaboration was first forged, Novartis has slowly stepped away from the partnership. In 2019, the Swiss pharma giant backed away from developing XmAb13676, a CD20 x CD3 bispecific antibody, following a strategic pipeline reprioritization. Now, Novartis is terminating rights to the vibecotamab program, effective February 2022. In 2019, shortly after Novartis dumped development rights to XmAb13676, the other asset was hit with a partial clinical hold by the U.S. Food and Drug Administration. The CD123 x CD3 blood cancer bispecific was assessed in a Phase I study for acute myeloid leukemia. Two patients in the trial died. CD123 is a tumor-associated antigen overexpressed on the surface of some tumor cells. The CD3 complex is a group of proteins on the surface of T-cells. Multiple companies have taken this approach against leukemia, but results have been less than encouraging. In 2016, Janssen and Genmab saw a hold placed on their CD123 x CD3 candidate for acute myeloid leukemia. Cellectis also caught a clinical hold on two Phase I trials of its CD123 asset, UCART123. Xencor announced Novartis’ decision in its third quarter financial report. The company stated that it would continue the ongoing study of vibecotamab, but it no longer intends further internal development of the drug once it is complete. There is still hope that something from the partnership with Novartis could be salvaged through the development of another asset. Earlier this year, the larger company selected a candidate to develop. The outcome for that study is still off in the future. Although the partnership with Novartis has taken a significant blow, Xencor could see fruit from a collaboration with Janssen. In October, the two companies entered into a partnership to advance the development of plamotamab and XmAb CD28 bispecific antibody combinations to treat patients with B-cell malignancies. Under terms of that deal, Janssen secured exclusive worldwide development and commercial rights to plamotamab, an investigational tumor-targeted XmAb bispecific antibody, currently in Phase I clinical development as a potential treatment for patients with CD20-expressing hematologic malignancies. Xencor is paying 20% of costs, including those for a subcutaneous formulation study that is expected to enter clinical studies in 2022. In the meantime, Xencor will continue, at its own expense, the combination study of plamotamab, tafasitamab and lenalidomide. Xencor is also partnered with Bristol Myers Squibb on the development of potential antibody treatment for COVID-19. The two companies will advance the development of Xencor’s Xtend Fc technology.
