Utilizing CD30 expression as a rational target for therapy of lymphoma


Rituximab, identified through pivotal lymphoma research, was the first monoclonal antibody approved by the US FDA in 1997. Since the success of rituximab, monoclonal antibodies have been a major focus for development of targeted agents for lymphoma treatment. A major hurdle in the development of a new antibody is finding a new target antigen. CD30 is an attractive therapeutic target antigen, because it has been identified as a marker of Reed–Sternberg cells in Hodgkin lymphoma (HL) [1], it is known to be expressed on anaplastic large cell lymphoma (ALCL), some cases of mediastinal large cell lymphoma, primary effusion lymphoma and multiple myeloma. However, its expression on normal tissues is restricted to a small number of activated B- and T-lymphocytes [2]. Thus, based on its expression pattern, CD30 could be an ideal therapeutic target.

Naked CD30 targeting antibodies and modified/engineered anti-CD30 antibodies

Although CD30 is considered an ideal target, the results from early clinical trials with first-generation naked monoclonal antibodies targeting CD30 have been disappointing.

Iratumumab (MDX-60) is a fully humanized anti-CD30 monoclonal antibody. Of 72 patients with HL or ALCL, clinical responses were observed in 6 (4 complete response [CR] and 2 partial response [PR]) [3]. SGN-30 is a chimeric anti-CD30 monoclonal antibody. In a phase I trial, one CR was reported in a patient with cutaneous ALCL [4]. In a phase II trial for HL or ALCL, 7 responses (2 CR, 5 PR) in patients with ALCL were reported in 79 patients. Unfortunately, there were no responders in the 38 HL patients [5].

XmAb2513 is a modified anti-CD30 antibody with increased binding affinity to the Fc receptor. In vitro data showed more potent and efficacious cell killing than first-generation anti-CD30 monoclonal antibodies XDA-060 and SGN-30. In clinical trials, only phase I data are available. Therefore, the data are insufficient to assess whether the response is better than that with unmodified antibodies [6].


Radiation itself is quite an efficient tool for killing lymphoma cells. If a good radiation source, a well-targeted monoclonal antibody and a conjugation technique are available, a radioimmunotherapeutic agent can be a good option in lymphoma treatment. Already radioimmunoconjugations using diverse radionuclides (including 90Y and 131I) are being investigated. In a preclinical animal model, the survival of mice was significantly prolonged by treatment with anti-CD30 antibody HeFi-1 coupled to 90Y [7]. The novel anti-CD30 monoclonal antibody Ki-4 conjugated with 131I (total dose 0.0035–0.99 Gy) was trialed in 22 patients with refractory or relapsed HL. One CR, 5 PRs, and 3 minor responses were achieved. However, 7 patients experienced grade 4 hematologic toxicity 4 to 8 weeks after treatment. Therefore, the development of this drug did not continue [8].

Antibody–drug conjugate: brentuximab–vedotin (SGN-35)

Brentuximab–vedotin (SGN-35) is an anti-CD30 monoclonal antibody conjugated to monomethyl auristatin E (MMAE), a synthetic antitubulin agent. Through binding with CD30, brentuximab–vedotin is internalized. Inside the lysosomes of lymphoma cells, free MMAE is released. Therefore, no immune response is required to achieve efficacy [9].

Two phase I trials with different schedules (treatment every 3 weeks or weekly) have been conducted. In the schedule with treatment every 3 weeks, the maximal tolerated dose was 1.8 mg/kg. Objective responses were observed in 17 of 45 relapsed or refractory CD30-positive hematologic malignancies including HL and ALCL. Of the responders, 11 achieved CR [10]. In a phase II trial with 102 patients with relapse after autologous stem cell transplantation (ASCT), who were treated with 1.8 mg/kg every 3 weeks, the overall response was around 75% (32% CR) with a median duration of response of 6.7 months. In a single arm phase II trial including 58 relapsed systemic ALCL patients, the overall response was 86% (58% CR), with a median duration of response of 12.6 months.

Based on these excellent outcomes, brentuximab–vedotin was approved by the FDA in August 2011. In HL patients, brentuximab–vedotin is indicated after the failure of ASCT or after the failure of at least two prior regimens of combination chemotherapy if the patients are not ASCT candidates. In systemic ALCL patients, it is approved after failure of at least one prior multiagent chemotherapy.

Overcoming the limitations of anti-CD30 targeting antibodies

Based on its expression patterns, CD30 should be a good therapeutic target. However, it can be shed in a soluble form, resulting in a reduction in the effect of anti-CD30 monoclonal antibodies by competitive binding. Thus, developing a monoclonal antibody targeting membrane-associated CD30 epitopes (Ep2: amino acids 107–153, Ep7 amino acids 282–338) may have potential advantages [11]. Although antibodies have exquisite selectivity for tumor over normal tissue, antibody localization to tumors is inefficient. Diabodies (50–55 kDa) can penetrate tumor more rapidly and accumulate more drug in tumors because they are smaller than IgG (150 kDa). An anti-CD30 diabody–drug conjugate (diabody-vcF4) showed potent antitumor activity and tolerable toxicity in a mouse model [12].

Future directions

After the early success of anti-CD30 monoclonal antibodies, a variety of clinical trials are ongoing. These antibodies can be combined as a part of first-line treatment, for example, combining ABVD with different levels of SGN-35, as part of salvage combination chemotherapy, maintenance, or as part of a conditioning regimen. After more information is obtained through clinical trials in the near future, new therapeutic strategies can be defined.
