News from the FDA/CDC

The US Food and Drug Administration (FDA) approved ribociclib (Kisqali, Novartis) in combination with an aromatase inhibitor for adult patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative stages II and III breast cancer at high risk for recurrence following surgery.

FDA also approved ribociclib and the aromatase inhibitor letrozole packaged together (Kisqali Femara Co-Pack, Novartis) for the same indication.

A rival cyclin-dependent kinase 4/6 (CDK4/6) inhibitor abemaciclib (Verzenio, Eli Lilly) carries a similar adjuvant indication, but use of this agent requires patients to be lymph node–positive.

There’s no such restriction for the new ribociclib indication, which “allows us to offer treatment with a CDK4/6 inhibitor to a significantly broader group of people,” lead investigator Dennis J. Slamon, MD, breast oncologist at the University of California Los Angeless, said in a Novartis press release.

The new indication joins ribociclib’s previous approval for advanced or metastatic HR-positive, HER2-negative breast cancer in combination with an aromatase inhibitor or fulvestrant.

The current approval was based on data from the NATALEE trial. NATALEE randomized 5101 patients with early-stage HR-positive, HER2-negative disease to either 400 mg ribociclib with an aromatase inhibitor or to an aromatase inhibitor alone following surgery. 

Invasive disease-free survival at 36 months was 90.7% in the ribociclib arm vs 87.6% with aromatase inhibitor monotherapy (hazard ratio [HR], 0.749; P = .0006). The trial included patients with and without lymph node involvement.

At 4 years (well beyond NATALEE’s 3-year treatment window), the ribociclib group continued to do better, with an invasive disease-free survival rate of 88.5% vs 83.6% in the control arm.

Overall survival data remain immature but with a trend towards improved survival in the ribociclib arm (HR, 0.715; P < .0001), according to a recent report from the 2024 European Society for Medical Oncology Congress.

There were no new safety signals in the trial. Adverse events in the ribociclib group included neutropenia (62.5% overall; 44.3% grade 3/4), liver-related events (26.4% overall; 8.6% grade 3/4), QT prolongation (5.3% overall; 1.0% grade 3/4), and interstitial lung disease/pneumonitis (1.5% overall; 0.0% grade 3/4), according to Novartis.

Ribociclib dosing for the adjuvant indication is lower than for metastatic disease, but patients are on the same schedule — two 200 mg tablets once daily for 21 days followed by 7 days off in 28-day cycles. Treatment continues for 3 years.

Forty-two 200 mg tablets cost about $15,000, according to drugs.com. A patient assistance program is available through Novartis.

The Food and Drug Administration (FDA) has approved benralizumab (Fasenra) for the treatment of adults with eosinophilic granulomatosis with polyangiitis (EGPA), formerly known as Churg-Strauss syndrome.

The drug is the second approved biologic for the treatment of EGPA. The first, mepolizumab (Nucala), was approved in 2017.

“This disease has a devastating impact on patients and the quality of their life, and they need more treatment options. The approval of another treatment in EGPA is welcome news to the approximately 15,000 patients living in the US with this difficult-to-treat rare disease,” said Joyce Kullman, executive director of the Vasculitis Foundation, in a press release on September 18. 

Benralizumab, developed by AstraZeneca, is a monoclonal antibody against the interleukin-5 alpha receptor expressed on eosinophils. The drug was first approved in 2017 as an add-on treatment for patients 12 years and older with severe eosinophilic asthma, and is now approved for use in children aged 6 years and older. 

The new indication was based on positive results from a noninferiority trial comparing benralizumab and mepolizumab. For the trial, published in the New England Journal of Medicine earlier in 2024, 140 adults with relapsing or refractory EGPA were randomized to a 30-mg subcutaneous injection of benralizumab or three separate 100-mg mepolizumab injections every 4 weeks for 1 year. At weeks 36 and 48, 59% of patients in the benralizumab group and 56% of patients in the mepolizumab group achieved remission (95% CI, –13 to 18; P = .73 for superiority). From week 42 to 52, 41% of patients who received benralizumab completely stopped taking oral glucocorticoids, compared with 26% of those who received mepolizumab.

“Patients often rely on long-term oral corticosteroids, which can cause serious and lasting side effects. Benralizumab is a much-needed treatment option, with data showing that not only is remission an achievable goal for EGPA patients, but benralizumab can also help patients taper off steroid therapy,” Michael Wechsler, MD, director of The Asthma Institute at National Jewish Health in Denver, Colorado, and the international coordinating investigator for the clinical trial, said in the press release.

Benralizumab is administered via subcutaneous injection. In adults with EGPA, the recommended dosage is 30 mg every 4 weeks for the first three doses, then once every 8 weeks.

The most common adverse reactions include headache and pharyngitis, according to the prescribing information. 

Benralizumab is also in development for the treatment of chronic obstructive pulmonary disease, chronic rhinosinusitis with nasal polyps, and hypereosinophilic syndrome.

The Food and Drug Administration (FDA) has approved atezolizumab and hyaluronidase-tqjs (Tecentriq Hybreza, Genentech) as a subcutaneous injection in adults, covering all approved indications of the intravenous (IV) formulation.

Approved indications include non–small cell lung cancer (NSCLC), SCLC, hepatocellular carcinoma, melanoma, and alveolar soft part sarcoma. Specific indications are available with the full prescribing information at Drugs@FDA.

This is the first programmed death–ligand 1 inhibitor to gain approval for subcutaneous administration.

“This approval represents a significant option to improve the patient experience,” Ann Fish-Steagall, RN, Senior Vice President of Patient Services at the LUNGevity Foundation stated in a Genentech press release.

Subcutaneous atezolizumab and hyaluronidase-tqjs was evaluated in the open-label, randomized IMscin001 trial of 371 adult patients with locally advanced or metastatic NSCLC who were not previously exposed to cancer immunotherapy and who had disease progression following treatment with platinum-based chemotherapy. Patients were randomized 2:1 to receive subcutaneous or IV administration until disease progression or unacceptable toxicity.

Atezolizumab exposure, the primary outcome measure of the study, met the lower limit of geometric mean ratio above the prespecified threshold of 0.8 (cycle 1C trough, 1.05; area under the curve for days 0-21, 0.87).

No notable differences were observed in overall response rate, progression-free survival, or overall survival between the two formulations, according to the FDA approval notice.

The confirmed overall response rate was 9% in the subcutaneous arm and 8% intravenous arm.

Adverse events of any grade occurring in at least 10% of patients were fatigue, musculoskeletal pain, cough, dyspnea, and decreased appetite.

The recommended dose for subcutaneous injection is one 15 mL injection, which contains 1875 mg of atezolizumab and 30,000 units of hyaluronidase.

Injections should be administered in the thigh over approximately 7 minutes every 3 weeks. By contrast, IV administration generally takes 30-60 minutes.

The US Food and Drug Administration (FDA) has approved lazertinib (Lazcluze) in combination with amivantamab-vmjw (Rybrevant) for upfront treatment of adults with locally advanced or metastatic non–small-cell lung cancer (NSCLC) who have EGFR exon 19 deletions or exon 21 L858R substitution mutations as detected by an FDA-approved test. 

This marks the first approval for lazertinib. Amivantamab was initially approved by the FDA in 2021 and carries a few indications for locally advanced or metastatic NSCLC. Both drugs are manufactured by Janssen Biotech Inc.

“Patients will now have the option of a potential new first-line standard of care with significant clinical benefits over osimertinib,” study investigator Alexander Spira, MD, PhD, director, Virginia Cancer Specialists Research Institute, said in a news release from Johnson & Johnson . 

Lazertinib is an oral, highly selective, third-generation EGFR tyrosine kinase inhibitor that can penetrate the brain and amivantamab is a bispecific antibody targeting EGFR and MET.

The approval was based on results from the phase 3 MARIPOSA trial, which showed that the combination reduced the risk of disease progression or death by 30% compared with osimertinib.

The MARIPOSA trial randomly allocated 1074 patients with exon 19 deletion or exon 21 L858R substitution mutation-positive locally advanced or metastatic NSCLC and no prior systemic therapy for advanced disease to amivantamab plus lazertinib, osimertinib alone, or lazertinib alone.

Lazertinib plus amivantamab demonstrated a statistically significant improvement in progression-free survival compared with osimertinib (hazard ratio, 0.70; P < .001). Median progression-free survival was 23.7 months with the combination vs 16.6 months osimertinib alone and 18.5 months with lazertinib alone.

The median duration of response was 9 months longer with the combination compared with osimertinib (25.8 months vs 16.7 months).

The most common adverse reactions (≥ 20%) were rash, nail toxicity, infusion-related reactions (amivantamab), musculoskeletal pain, edema, stomatitis, venous thromboembolism, paresthesia, fatigue, diarrhea, constipation, COVID-19, hemorrhage, dry skin, decreased appetite, pruritus, nausea, and ocular toxicity. 

“A serious safety signal of venous thromboembolic events was observed with lazertinib in combination with amivantamab and prophylactic anticoagulation should be administered for the first four months of therapy,” the FDA noted in a statement announcing the approval.

Results from MARIPOSA were first presented at the European Society for Medical Oncology 2023 Congress and published in The New England Journal of Medicine in June. Longer-term follow-up data from MARIPOSA will be presented at the International Association for the Study of Lung Cancer 2024 World Congress on Lung Cancer in September.

The Food and Drug Administration (FDA) has approved durvalumab (Imfinzi; AstraZeneca) both before and after surgery in patients with resectable non–small cell lung cancer (NSCLC) without EGFR mutations or ALK rearrangements. The agency approved durvalumab alongside platinum-containing chemotherapy in the neoadjuvant setting and as monotherapy in the adjuvant setting.

The approval comes shortly after a meeting of FDA’s Oncology Drug Advisory Committee, where agency personnel took AstraZeneca to task for not following its request to include an arm in the approval study, AEGEAN, to clarify whether or not treatment after surgery was necessary. 

Even so, advisers at the July 25 meeting voted “yes” to approving the neoadjuvant/adjuvant indication to give patients another immunotherapy option in NSCLC. However, the committee voted unanimously that, going forward, the agency should require — instead of simply request — that companies seeking combined neoadjuvant/adjuvant NSCLC indications show that patients actually need treatment after surgery. 

The new approval is durvalumab’s first indication for resectable NSCLC. The agent has been previously approved for unresectable or metastatic disease as well as extensive-stage small cell lung cancer, locally advanced or metastatic biliary tract cancer, unresectable hepatocellular carcinoma, and advanced or recurrent endometrial cancer. 

AEGEAN included 802 patients with previously untreated and resectable stage IIA-IIIB squamous or nonsquamous NSCLC. Patients were randomly assigned to receive either durvalumab (400 patients) or placebo (402 patients) on a background of platinum-based chemotherapy every 3 weeks for four cycles then, following surgery, durvalumab or placebo once a month for a year. 

The pathologic complete response rate was 17% in the durvalumab arm vs 4.3% in the placebo arm. At 12 months, event-free survival was 73.4% with durvalumab vs 64.5% with placebo. Overall survival differences have not been tested for statistical significance, but there was “no clear detriment” with durvalumab, FDA said in a press release. 

Adverse reactions in 20% or more of durvalumab recipients included anemia, nausea, constipation, fatigue, musculoskeletal pain, and rash; 1.7% of durvalumab recipients and 1% of placebo recipients could not have surgery because of side effects during neoadjuvant treatment. 

The dosage for patients weighing > 30 kg is 1500 mg every 3 weeks before surgery and every 4 weeks afterward. For patients who weigh less than that, the recommended dosage is 20 mg/kg. 

Durvalumab costs around $1,053 for 120 mg, according to drugs.com.

The US Food and Drug Administration (FDA) granted accelerated approval for Livdelzi (seladelpar, Gilead Sciences, Inc.) for primary biliary cholangitis (PBC) in combination with ursodeoxycholic acid (UDCA) in adults who fail to respond adequately to UDCA, or as monotherapy in those who can’t tolerate UDCA. 

Livdelzi, a selective agonist of peroxisome proliferator–activated receptor delta, is not recommended in adults who have or develop decompensated cirrhosis.

PBC is a rare, chronic, autoimmune disease of the bile ducts that affects roughly 130,000 Americans, primarily women, and can cause liver damage and possible liver failure if untreated. The disease currently has no cure.

The FDA approved Livdelzi based largely on results of the phase 3 RESPONSE study, in which the drug significantly improved liver biomarkers of disease activity and bothersome symptoms of pruritus in adults with PBC.

The primary endpoint of the trial was a biochemical response, defined as an alkaline phosphatase (ALP) level < 1.67 times the upper limit of the normal range, with a decrease of 15% or more from baseline, and a normal total bilirubin level, at 12 months.

After 12 months, 62% of patients taking Livdelzi met the primary endpoint vs 20% of patients taking placebo.

In addition, significantly more patients taking Livdelzi than placebo had normalization of the ALP level (25% vs 0%). The average decrease in ALP from baseline was 42.4% in the Livdelzi group vs 4.3% in the placebo group.

At 12 months, alanine aminotransferase and gamma-glutamyl transferase levels were reduced by 23.5% and 39.1%, respectively, in the Livdelzi group compared with 6.5% and 11.4%, respectively, in the placebo group.

A key secondary endpoint was change in patient-reported pruritus.

At baseline, 38.3% of patients in the Livdelzi group and 35.4% of those in the placebo group had moderate to severe pruritus, with a daily numerical rating scale (NRS) score ≥ 4 out of 10.

Among these patients, the reduction from baseline in the pruritus NRS score at month 6 was significantly greater with Livdelzi than with placebo (change from baseline, -3.2 vs -1.7 points). These improvements were sustained through 12 months.

Improvements on the 5-D Itch Scale in both the moderate- to severe-pruritis population and the overall population also favored Livdelzi over placebo for itch relief, which had a positive impact on sleep.

“The availability of a new treatment option that can help reduce [the] intense itching while also improving biomarkers of active liver disease is a milestone for our community,” Carol Roberts, president, The PBCers Organization, said in a news release announcing the approval. 

The most common adverse reactions with Livdelzi were headache, abdominal pain, nausea, abdominal distension, and dizziness.

The company noted that the FDA granted accelerated approval for Livdelzi based on a reduction of ALP. Improvement in survival or prevention of liver decompensation events have not been demonstrated. Continued approval of Livdelzi for PBC may be contingent on verification and description of clinical benefit in confirmatory trial(s).

The Food and Drug Administration has approved denileukin diftitox-cxdl (Lymphir, Citius Pharmaceuticals) for adults with relapsed or refractory stage 1-3 cutaneous T-cell lymphoma after at least one prior systemic therapy.

The immunotherapy is a reformulation of denileukin diftitox (Ontak), initially approved in 1999 for certain patients with persistent or recurrent cutaneous T-cell lymphoma. In 2014, the original formulation was voluntarily withdrawn from the US market. Citius acquired rights to market a reformulated product outside of Asia in 2021. 

This is the first indication for Lymphir, which targets interleukin-2 receptors on malignant T cells.

This approval marks “a significant milestone” for patients with cutaneous T-cell lymphoma, a rare cancer, company CEO Leonard Mazur said in a press release announcing the approval. “The introduction of Lymphir, with its potential to rapidly reduce skin disease and control symptomatic itching without cumulative toxicity, is expected to expand the [cutaneous T-cell lymphoma] treatment landscape and grow the overall market, currently estimated to be $300-$400 million.” 

Approval was based on the single-arm, open-label 302 study in 69 patients who had a median of four prior anticancer therapies. Patients received 9 mcg/kg daily from day 1 to day 5 of 21-day cycles until disease progression or unacceptable toxicity.

The objective response rate was 36.2%, including complete responses in 8.7% of patients. Responses lasted 6 months or longer in 52% of patients. Over 80% of subjects had a decrease in skin tumor burden, and almost a third had clinically significant improvements in pruritus. 

Adverse events occurring in 20% or more of patients include increased transaminases, decreased albumin, decreased hemoglobin, nausea, edema, fatigue, musculoskeletal pain, rash, chills, constipation, pyrexia, and capillary leak syndrome.

Labeling carries a boxed warning of capillary leak syndrome. Other warnings include visual impairment, infusion reactions, hepatotoxicity, and embryo-fetal toxicity. Citius is under a postmarketing requirement to characterize the risk for visual impairment.

The company expects to launch the agent within 5 months.

The US Food and Drug Administration (FDA) has approved vorasidenib (Voranigo, Servier) for the treatment of certain isocitrate dehydrogenase (IDH)–mutant diffuse gliomas, marking the first approval of a targeted therapy for these types of brain tumors.

Specifically, the oral targeted inhibitor of IDH1 and IDH2 was approved for use after surgery in adults and children aged 12 years or older who have grade 2 astrocytoma or oligodendroglioma with a susceptible IDH1 or IDH2 mutation. According to the FDA, surgery includes biopsy, subtotal resection, or gross total resection. 

Mutations in IDH1 are present in around 80% of grade 2 gliomas, whereas IDH2 mutations are more infrequent, occurring in about 4%. 

Prior to the approval, which was based on progression-free survival (PFS) and safety findings from the pivotal phase 3 INDIGO trial, patients with this type of glioma had limited treatment options, said a Servier spokesperson.

The approval of vorasidenib marks “one of the biggest advances in low-grade glioma in more than two decades” and “will empower patients to take active control of their disease with a once-daily pill,” according to the spokesperson.

In the INDIGO trial, 331 patients were randomly assigned to receive 40 mg of vorasidenib once daily (n = 168) or placebo (n = 163). At a median follow-up of 14.2 months, the median PFS was more than twice as long among those who received vorasidenib vs placebo: 27.7 months vs 11.1 months, respectively (hazard ratio [HR] for disease progression or death, 0.39). The time to next intervention was also significantly longer with vorasidenib vs placebo (median not reached vs 17.8 months, respectively; HR, 0.26).

The 61% reduction in the risk for tumor progression or death observed in the trial represents “a significant sign of efficacy that has the potential to change the landscape in this disease,” first author Ingo K. Mellinghoff, MD, of Memorial Sloan Kettering Cancer Center, New York City, told this news organization in 2023, when presenting the findings at the 2023 American Society of Clinical Oncology conference. These findings were simultaneously published in The New England Journal of Medicine.

Glenn Lesser, MD, a discussant at the 2023 meeting, commented on the “striking” findings. The results are “statistically highly significant, and more importantly, they’re clinically very, very significant,” said Dr. Lesser, from Wake Forest Baptist Health in Winston-Salem, North Carolina.

Vorasidenib can also potentially delay the use of toxic chemotherapies and radiation for many years in patients with these tumors, Dr. Lesser added.

Adverse events of grade 3 or higher occurred in 22.8% of those who received vorasidenib and in 13.5% of those in the placebo group. Increased alanine aminotransferase levels of grade 3 or higher occurred in 9.6 vs 0% of patients in the groups, respectively.

The most common adverse reactions with vorasidenib, affecting at least 15% of treated patients, include fatigue, headache, COVID-19, musculoskeletal pain, diarrhea, nausea, and seizure. The most common grade 3 or 4 laboratory abnormalities were increased alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transpeptidase as well as decreased neutrophils. 

The recommended dose of vorasidenib for adults is 40 mg given orally once daily until disease progression or unacceptable toxicity. In children aged 12 or older, the recommended dose is 40 mg given orally once daily for those weighing ≥ 40 kg, and 20 mg given orally once daily for those weighing < 40 kg.

Vorasidenib can also potentially delay the use of toxic chemotherapies and radiation for many years in patients with these tumors, Dr. Lesser added.

Adverse events of grade 3 or higher occurred in 22.8% of those who received vorasidenib and in 13.5% of those in the placebo group. Increased alanine aminotransferase levels of grade 3 or higher occurred in 9.6 vs 0% of patients in the groups, respectively.

The most common adverse reactions with vorasidenib, affecting at least 15% of treated patients, include fatigue, headache, COVID-19, musculoskeletal pain, diarrhea, nausea, and seizure. The most common grade 3 or 4 laboratory abnormalities were increased alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transpeptidase as well as decreased neutrophils. 

The recommended dose of vorasidenib for adults is 40 mg given orally once daily until disease progression or unacceptable toxicity. In children aged 12 or older, the recommended dose is 40 mg given orally once daily for those weighing ≥ 40 kg, and 20 mg given orally once daily for those weighing < 40 kg.

The US Food and Drug Administration (FDA) has approved afamitresgene autoleucel (afami-cel) (Tecelra, Adaptimmune LLC) to treat advanced synovial sarcoma. 

Afami-cel — the first engineered cell therapy for a solid tumor — is indicated specifically for adults with unresectable or metastatic synovial sarcoma who have received prior chemotherapy, are positive for several human leukocyte antigens (HLAs), and whose tumors express melanoma-associated antigen A4, as determined by FDA-authorized companion diagnostic devices.

The single-dose treatment targets solid tumors expressing melanoma-associated antigen A4, a protein highly expressed in synovial sarcoma.

Synovial sarcoma is a rare form of cancer, which affects about 1000 people in the US each year. Malignant cells develop and form a tumor in soft tissues, often in the extremities. 

“Adults with metastatic synovial sarcoma, a life-threatening form of cancer, often face limited treatment options in addition to the risk of cancer spread or recurrence,” Nicole Verdun, MD, director of the Office of Therapeutic Products in the FDA’s Center for Biologics Evaluation and Research, said in the agency press release announcing the approval. “Today’s approval represents a significant milestone in the development of an innovative, safe and effective therapy for patients with this rare but potentially fatal disease.”

T-cell receptor therapy, like chimeric antigen receptor (CAR) T-cell (CAR-T) therapy, involves altering patient T cells to fight cancer. While CAR-T therapy inserts an artificial receptor to target a specific surface protein on cancer cells, the T-cell receptor therapy modifies existing receptors to recognize an array of antigens on the surface of cancer cells — a promising strategy for targeting solid tumors. 

The accelerated approval of afami-cel was based on the phase 2 SPEARHEAD-1 trial in 44 patients with synovial sarcoma who received a single infusion of the therapy. The trial had enrolled 52 patients, but 8 did not receive afami-cel, including 3 who died and 1 who withdrew. 

According to the FDA announcement, the overall response rate was 43.2%, with a median time to response of 4.9 weeks. The median duration of response was 6 months (95% CI, 4.6 months to not reached). Among patients who responded, 39% had a duration of response of 12 months or longer.

“These results suggest that a one-time treatment with afami-cel has the potential to extend life while allowing responders to go off chemotherapy,” said lead investigator Sandra D’Angelo, MD, a sarcoma specialist at Memorial Sloan Kettering Cancer Center in New York City, in a company press release.

The prescribing information includes a boxed warning for serious or fatal cytokine release syndrome.

The most common nonlaboratory adverse reactions, occurring in at least 20% of patients, included cytokine release syndrome, nausea, vomiting, fatigue, infections, pyrexia, constipation, dyspnea, tachycardia, hypotension, diarrhea, and edema. The most common grade 3 or 4 laboratory abnormalities, occurring in at least 20% of patients, included decreased lymphocyte count, neutrophil count, white cell blood count, red blood cell, and platelet count.

The recommended dose is between 2.68x109 to 10x109 MAGE-A4 T-cell receptor–positive T-cells. The FDA notice specifies not using a leukodepleting filter or prophylactic systemic corticosteroids.

The list price for the one-time therapy is $727,000, according to Fierce Pharma.

The US Food and Drug Administration (FDA) has expanded the approval of dostarlimab-gxly (Jemperli, GSK) in conjunction with carboplatin and paclitaxel, followed by single-agent dostarlimab-gxly, for adults with primary advanced or recurrent endometrial cancer.

Prior FDA approval of the combination was granted for adults with primary advanced or recurrent endometrial cancer that was mismatch repair deficient (dMMR) or microsatellite instability–high (MSI-H).

The expanded approval, granted following a priority review, was based on efficacy and safety demonstrated in the randomized, controlled, multicenter RUBY trial, which included 494 patients who were randomized to receive the dostarlimab-gxly regimen or placebo plus carboplatin and paclitaxel, followed by placebo.

Researchers observed a significant improvement in median overall survival with treatment vs placebo in the overall population — 44.6 vs 28.2 months, respectively (hazard ratio [HR], 0.69). Median progression-free survival was also significantly better in the treatment vs placebo group — 11.8 vs 7.9 months, respectively (HR, 0.64).

“Today’s expanded approval will offer even more patients the opportunity for improved outcomes,” Matthew Powell, MD, of Washington University School of Medicine, and principal investigator on the RUBY trial, said in a press release. “This is the only immuno-oncology treatment regimen that has shown a statistically significant overall survival benefit for the full patient population, which is a meaningful step forward in treating this challenging cancer.”

Adverse reactions occurring in at least 20% of patients receiving dostarlimab-gxly include anemia, increased creatinine levels, peripheral neuropathy, decreased white blood cell counts, fatigue, nausea, alopecia, low platelet counts, increased glucose levels, lymphopenia, neutropenia, liver function test abnormalities, arthralgia, rash, constipation, diarrhea, decreased albumin levels, abdominal pain, dyspnea, decreased appetite, increased amylase levels, urinary tract infection, and vomiting. Immune-mediated adverse reactions with dostarlimab-gxly were similar to those previously reported.

The recommended dostarlimab-gxly dose, according to the full prescribing information, is 500 mg every 3 weeks for six cycles administered before carboplatin and paclitaxel if given on the same day, followed by 1000 mg monotherapy every 6 weeks until disease progression or unacceptable toxicity, or up to 3 years.
