ASH 2024 Preview for Community Oncologists: The Show and After Show

The American Society of Hematology (ASH) Annual Meeting and Exposition aims to educate oncology providers across an array of hematologic malignancies, with a focus on novel agents, drugs across the FDA pipeline, and more.

, co-hosts Kristie L. Kahl and Andrew Svonavec offer a glimpse at some of the presentations guaranteed to spark one’s curiosity, spur debate, and enhance the field even further. Some key highlights include:

 Continued advancements in CAR T-cell therapy are expected to revolutionize the treatment of hematologic malignancies.

 Bispecific antibodies, such as Epcoritamab (Epkinly), offer a novel approach to target multiple antigens on cancer cells.

 The assessment of MRD is becoming increasingly important in predicting treatment response and overall survival.

Advances in Acute Lymphoblastic Leukemia (ALL)

Blinatumomab (Blincyto) in pediatric ALL:

 The addition of blinatumomab to chemotherapy has shown promise in improving disease-free survival in high-risk pediatric ALL. This combination therapy may offer a more effective treatment option for young patients.

Acalabrutinib (Calquence) in mantle cell lymphoma (MCL):

 The FDA is set to review the approval of acalabrutinib with bendamustine or rituximab (Rituxan) for previously untreated MCL, based on data from the phase 3 ECHO trial (NCT02972840).

Asciminib (Scemblix) in chronic phase chronic myelogenous leukemia (CML-CP):

 The FDA recently granted accelerated approval to asciminib for newly diagnosed CML-CP. This tyrosine kinase inhibitor has shown favorable safety and tolerability profiles.

The biologics license application (BLA) of the subcutaneous formulation of nivolumab (Opdivo) coformulated with human hyaluronidase (rHuPH20) has been accepted by the FDA.

Findings from the CheckMate -67T (NCT04810078) support this BLA of subcutaneous nivolumab as the trial met its coprimary pharmacokinetic end points and key secondary end point of overall response rate (ORR) vs intravenous (IV) nivolumab in clear cell renal cell carcinoma.

The FDA has set a Prescription Drug User Fee Act (PDUFA) goal date for December 29, 2024.

The FDA has accepted the BLA of the subcutaneous formulation of nivolumab coformulated with rHuPH20, also known as subcutaneous nivolumab, for all previously approved adult solid tumor indications of nivolumab as a monotherapy, monotherapy maintenance following completion of the combination therapy with nivolumab plus ipilimumab (Yervoy), or in combination with chemotherapy or cabozantinib (Cabometyx).

Results from the phase 3 CheckMate -67T trial of subcutaneous nivolumab support this application. In the trial, experts sought to evaluate subcutaneous nivolumab vs its intravenous (IV) formulation.

 Here, the subcutaneous form demonstrated noninferior pharmacokinetics and efficacy, as well as consistent safety compared with the IV formulation of nivolumab among patients with advanced or metastatic clear cell renal cell carcinoma (ccRCC) who have received prior systemic therapy.

A PDUFA goal date has been set for December 29, 2024. With this, subcutaneous nivolumab shows promise to become the first and only subcutaneously administered PD-1 inhibitor.

“We believe subcutaneous nivolumab has the potential to make a significant difference in the lives of patients, which is reinforced by the FDA’s acceptance of our application,” said Gina Fusaro, PhD, vice president, global program lead, Bristol Myers Squibb, in a press release.

“[Nivolumab] is a foundational PD-1 inhibitor approved for many different types of cancer, and our continued investment in research that puts patients first remains a priority. If approved by the FDA, the subcutaneous administration of nivolumab would provide patients and their physicians with a new option that delivers the same well-known benefits as IV [nivolumab] but with the improved convenience of an injection administered in 3 to 5 minutes rather than a 30- to 60-minute infusion,” Fusaro continued.

The phase 3, randomized, open-label CheckMate -67T trial is exploring subcutaneous administration of nivolumab coformulated with rHuPH20 vs IV nivolumab for the treatment of patients with advanced or metastatic ccRCC who were previously treated with systemic therapy.

In the study, 495 patients were randomly assigned to receive either subcutaneous nivolumab or IV nivolumab. Enrollment was open to patients with a histological confirmation of ccRCC, advanced RCC not amenable to curative or radiation therapy, metastatic RCC, those who received no more than 2 prior systemic therapies, those with intolerance or progression after last treatment regimen within 6 months of randomization, and those with a Karnofsky performance score ≥ 70 at screening.

Experts assessed the coprimary end points of time-averaged serum concentration over 28 days and trough serum concentration at steady-state of subcutaneous nivolumab vs IV nivolumab. A key secondary end point of the trial was ORR.

The study met its coprimary pharmacokinetic end points and key secondary end point of ORR with subcutaneous nivolumab in this patient population.

 Subcutaneous nivolumab was noninferior in regard to time-averaged nivolumab serum concentration over 28 days and steady-state trough serum concentration vs treatment with IV nivolumab. Additionally, subcutaneous nivolumab also demonstrated a noninferior ORR compared with IV nivolumab.

FDA Accepts BLA for Subcutaneous Nivolumab Across Various Solid Tumors

The FDA has approved the combination of sotorasib (Lumakras) and panitumumab (Vectibix) for the treatment of patients with previously treated 

 G12C-mutated metastatic colorectal cancer (CRC).

The approval is supported by data from the CodeBreaK 300 (NCT05198934) study.

The combination led to improvements in progression-free survival (PFS) and overall response rate (ORR) vs investigator’s choice of standard of care.

Sotorasib plus panitumumab has been approved by the FDA for the treatment of patients with previously treated CRC harboring a 

Data from the phase 3 CodeBreaK 300 study presented at the 

 support this approval. At a median follow-up of 7.8 months, the median PFS in patients treated with sotorasib 960 mg plus panitumumab was 5.6 months (HR, 0.49; 95% CI; 0.30-0.80), and the median PFS in patients treated with sotorasib 240 mg plus panitumumab was 3.9 months (HR, 0.58; 95% CI, 0.36-0.93). Comparatively, the median PFS in patients treated with investigator’s choice of trifluridine and tipiracil or regorafenib (Stivarga) was 2.2 months (95% CI, 1.9-3.9).

The most common grade 3 or higher treatment-related adverse effects in the combination arm were dermatitis acneiform (960 mg, 11%; 240 mg, 4%), hypomagnesemia (6%; 8%), rash (6%; 2%), and diarrhea (4%; 6%).

In September 2006, the FDA granted approval to panitumumab for the treatment of patients with EGFR-expressing, metastatic CRC with disease progression on or following fluoropyrimidine-, oxaliplatin-, and irinotecan-containing chemotherapy regimens.

In May 2021, the granted accelerated approval to sotorasib for the treatment of locally advanced or metastatic 

 G12C-mutated non–small cell lung cancer that had received at least 1 prior line of therapy, supported by data from the phase 2 CodeBreaK 100 study (NCT03600883).

In October 2023, the FDA’s Oncologic Drug Advisory Committee voted 10 to 2 that the PFS data from CodeBreaK 200 (NCT04303780) could not be reliably interpreted, as the PFS difference between the sotorasib and docetaxel control arms was small, and there was no difference in overall survival.

Polatuzumab vedotin ± rituximab ± bendamustine

What therapies would you consider for a patient like this? ​

Who is involved in the decision making?​

 More than half of you would think about tafasitamab [Monjuvi] plus lenalidomide [Revlimid] and then a little bit more than a third would consider the polatuzumab [Polivy] combination [with bendamustine and rituximab (Rituxan)], and some would consider a gemcitabine-based regimen.

It sounds like nearly all of you would treat this patient within the context of your practice …while waiting for cell therapy as opposed to referring for a clinical trial or [stem cell] transplant. I’d love to hear from somebody who chose the polatuzumab option. It gives you a lot of plus/minuses there. Would you add rituximab or bendamustine to this [regimen], and how would you use that combination?

 I voted for that. What I’ve seen our transplanters prefer is to do polatuzumab/rituximab without the bendamustine pending collection.

 So you base that on your prior experience with the CAR T-cell therapy group that you work with and that being their preference. What’s your experience with using that? How comfortable are you with it? How well does it work to control disease?

 It’s reasonably tolerated. It’s not clear that the bendamustine adds much besides toxicity. In my limited experience, it’s helped people and it’s gotten people to CAR T-cell therapy. It’s been OK.

 It does what you’re expecting it to do.

 Let’s go on to someone who uses a tafasitamab/lenalidomide regimen; does anyone want to comment on your experience with that?

 I’ve used tafasitamab/lenalidomide in this setting. The main reason is because I find it easy to manage in terms of adverse events. It mostly seems to be driven by the lenalidomide which we can easily dose modify, and we’re used to doing that with not just lymphoma but myeloma, etc.

 What dose of lenalidomide do you find you end up giving most of those patients?

 I feel like my patients don’t tolerate the lenalidomide as well as what I see typically in the trials. I’m often going down to 10 mg for a lot of my patients…that’s what I’ve been seeing.

 There is nothing [unusual] about your practice. Patients don’t tolerate lenalidomide at the starting dose [of 25 mg] that they’re using in most of the trials.

 I agree with Dr Arjunan. Lenalidomide is the 1 I always adjust. I’m using [closer to] 15 mg lenalidomide. Ten milligrams is even better [tolerated] but I push 15 mg.

 I agree with my colleagues. I like the idea that you can give tafasitamab for a limited period of time and then continue on lenalidomide. There’s a lot of familiarity with lenalidomide from other malignancies, and we know how to dose adjust and what to monitor for.

 Does anybody worry about giving a CD19-directed therapy with tafasitamab before giving a CD19-directed CAR T-cell therapy?

During a Targeted Oncology case-based roundtable event, Christopher R. Flowers, MD, MS, discussed the choice of bridging therapy for a patient with relapsed/refractory diffuse large B-cell lymphoma who may receive CAR (chimeric antigen receptor) T-cell therapy. 

This is the second of 2 articles based on this event.
